Box 6006 Raleigh, NC 27628 PREFACE The North Carolina Office of Coastal Management and the North Carolina Natural Heritage Program, both units of the Department of Natural Resources and Community Development, have commissioned a series of natural areas inventories for ten counties in the coastal zone of this state. The Washington County inventory was conducted in 1982 and was financed by a Coastal Energy Impact Program (CEIP) grant. CEIP funded the Washington County survey because of the potential environmental impacts of peat mining and other energy -related development. The recommendations made in this report by J. Merrill Lynch and S. Lance Peacock are advisory. Their inventory and recom- mendations are designed to help state and federal agencies, county officials, resource managers, landowners and developers work out effective land management and preservation mechanisms to protect the six outstanding or exemplary natural areas described in this report. Agencies such as the N.C. Division of Environmental Management, Division of Land Resources, Division of Marine Fisheries, Wildlife Resources Commission, the U.S. Fish and Wildlife Service, U.S. Army Corps of Engineers, National Marine Fisheries Service, and Environmental Protection Agency should find this report useful, as may university re- searchers, private consultants, and private conservation groups. The Office of Coastal Management will use the report in assessing permit applications and for federal and state consistency reviews. Merrill Lynch and Lance Peacock are experienced field bio- logists, who have previously been employed with the N.C. Natural Heritage Program and are most familiar with natural habitats throughout the North Carolina coastal plain region. The investi- gators were exceptionally well qualified to identify, describe, and evaluate the most outstanding natural areas of the project region. Project investigators were instructed to identify those natural areas that contain highly unique, endangered, or rare natural features, or highest quality representations of rela- tively undisturbed natural habitats, and which may be vulnerable to threats and damage from land use changes. The investigators were advised not to report on Lake Phelps or Lake Pungo, which are both in protected status. (1) Pungo Lake. The 10,000-acre Pungo National Wildlife Refuge includes the 2,800-acre lake. The lake hosts a large wintering population of waterfowl. The lake is bordered on the northern shore by a band of mature swamp tupelo forest and on the east by a disturbed area of pocosin. The lake and portions of swamp forest and pocosin is recognized on the State Registry of Natural Heritage Areas. ii r (2) Lake Phelps. The 16,000-acre lake is the second largest natural lake in North Carolina. It is administered by the N.C. Division of Parks and Recreation. The lake contains several rare aquatic plant species and is a documented site for the endangered Waccamaw killifish (Fundulus waccamensis). The lake is also recognized on the State Registry of Natural Heritage Areas. The Office of Coastal Management, and the Coastal Resources Commission which it serves, implement the Coastal Area Manage- ment Act of 1974 (CAMA). Under this statute, the North Carolina Coastal Management Plan has been prepared and approved. It includes the definition and designation of various Areas of Environmental Concern (AEC). In many cases, AECs coincide with natural areas that are herein recommended for preservation or special management. Peat mining has particular implications for these natural areas, some of which overlay exploitable peat deposits. Mining will remove natural vegetation, permanently alter the hydrology of the region, lower surface soil types from high organic histo- soils to the clayey, sandy, and loamy soils typical of other parts of the outer coastal plain. Thus, natural communities, once mining is complete, almost certainly could never be re- established or reclaimed on mined -out land. Preservation of the best natural areas, and appropriate hydrological management is necessary prior to and during active peat mining. The Natural Heritage Program is most pleased to have had this opportunity to conduct this project for the Office of Coastal Management. The inventory has documented a number of high -quality natural areas that possess natural elements of statewide priority and are important parts of North Carolina's natural diversity. Most of the identified sites were previously unknown and undocumented by the state's scientific community. The Natural Heritage Program hopes that these areas will be protected for the benefits of present and future generations of North Carolina and for the preservation of the state's truly exceptional natural heritage. Charles E. Roe, Coordinator N.C. Natural Heritage Program November 16, 1982 i i i ABSTRACT. Six natural areas are described and delineated for Washington County as a result of a field survey December 1981-September 1982. The natural areas contain almost 14,200 acres and at least 36 significant features. The great majority of the natural area acreage is privately owned (98%). The only publicly owned natural areas are contained in Pettigrew State Park. A large fraction of the natural area acreage is com- prised of wetland forests. iv ACKNOWLEDGEMENTS The assistance of the following individuals is gratefully acknowledged: 1.

Chapel Swamp z 0 INTRODUCTION Washington County is in the northeastern section of North Carolina situated in the coastal plain province. The county has a total area of 420 square miles, including 336 square miles of land and 84 square miles of water. The 269,000 acres encompass a variety of habitats, ranging from open lakes and sounds to freshwater marshes, wooded swamps and pocosins, to upland hardwood, pine, and mixed forests. Washington County is primarily a rural county with only two municipalities, Plymouth, the county seat, and Roper. The 1970 census reported a county -wide population of 14,114, one of the least populated counties in the state. In addition to Albemarle Sound, it has contiguous boundaries with Tyrrell, Hyde, Beaufort, Martin, and Bertie Counties (Figure 1). The county lies across the divides of two major river basins. The northwestern part drains into the Roanoke River Basin, and the southern part drains into the Pungo River Basin. The rest of the county drains into Albemarle Sound. Elevation ranges from sea level at the Albemarle Sound to about 50 feet near the town of Hoke in the southwest corner. Geomorphologically, the county is divided into two coastal plain marine terraces, separated by two parallel scarps, which run northeast -southwest across the extreme western side. The Suffolk Scarp, otherwise known as the Pinetown Scarp, is a distinct sand ridge which marks an old ocean shoreline formed during a higher Pleistocene sea level. The toe, or base, of this scarp is about 25 feet and the marine terrace to the east is known as the Pamlico Terrace. West of the scarp is another relatively flat marine surface known as the Talbot Terrace, an older feature formed by an even higher Pleistocene sea. Two major freshwater lakes are a dominant part of the county landscape. Lake Phelps is 16,600 acres in size and is located in the southeastern portion of the county south of Creswell. It is the second largest natural lake in North Carolina. Pungo Lake, 2560 acres, is located in the southeastern portion of the county about three miles southwest of Lake Phelps. GEOLOGY The generalized geology of Washington County dates from the Cretaceous Period to the Recent. The county is underlain by a thick section of sedimentary deposits which consist mainly of sand, clay, marl, and limestone. Occurring throughout most of 1 the county is the Eocene Castle Hayne limestone, a chalky -white sandy -shell limestone or dense silicified gray limestone. Out- crops of this formation are not known for the county. Overlying the Castle Hayne are various deposits of the Miocene Yorktown formation consisting of blue -gray marls, sands, and shell beds interbedded with massive, dark, sandy clays. Overlying the York- town are the undifferentiated deposits of interbedded sands and clays of Pleistocene and Recent age which form the Talbot and Pamlico terraces mentioned earlier. SOILS AND VEGETATION The soils of Washington County are fairly diverse and play a major role in the geographical distribution and ecology of the major vegetation associations. The county has been mapped into seven basic soil associations each of which represent a distinct pattern of drainage, soils, relief and vegetation. Each unit is a unique natural landscape with a corresponding assemblage of vegetation types. Soils information is taken from Soil Survey of Washington County, N.C., Soil Conservation Service, 1981. 1) Augusta-Altavista-Wahee Association: These are nearly level, somewhat poorly drained and moderately well - drained soils that have a loamy surface layer and a loamy or clayey subsoil; on low ridges or stream terraces along small streams which drain into the Roanoke River or Albemarle Sound. Natural Area represented: Chapel Swamp Percentage of land area of county = 13% Because of their better drainage and location along the Roanoke River and Albemarle Sound, these soils were among the first to be cleared and placed in cultivation. The earliest settlements in the county around the present-day towns of Plymouth and Roper arose in areas dominated by this soilscape. Original vegetation probably consisted of a mixture of upland oaks, such as white, southern red, and black, with American beech, loblolly and shortleaf pines, and mockernut and pignut hickories. The Chapel Swamp natural area contains the best remaining example of this soilscape. 2) Cape Fear -Portsmouth -Roanoke Association: These are nearly level, very poorly drained and poorly drained soils that have a loamy surface layer and a loamy or clayey subsoil; on stream or marine terraces along interstream divides. 2 Natural Areas Represented: Pettigrew State Park (Lake Phelps) Percentage of land area of county: 40% This landscape occupies much of the county in the poorly drained interior situated between the upper reaches of the drainages and the peat -dominated wetlands in the central and southeastern sections. Essentially these are flat upland non -alluvial wetlands dominated by mineral soils. Most of the soilscape has been drained, cleared and converted to agriculture. Much of the remaining acreage, owned by large timber corporations, has been or is in the process of being drained and converted to large scale loblolly pine tree farms. Even though this landscape occupies a substantial part of the county, very little natural vegetation remains and that which is left has been subjected to extensive logging operations. The Lake Phelps baldcypress natural area, although included in this associ- ation unit, is probably not a typical vegetation type, because of the influence of adjacent Lake Phelps. The natural vegetation probably consisted of a number of wet- land hardwood and softwood species, including baldcypress, swamp blackgum, loblolly pine, tulip -poplar, American beech (locally), swamp chestnut, laurel, willow, water, and cherrybark oaks, red maple, and sweetgum. Ashe (1894) mentioned the occurrence of oak flats in coastal plain lowlands slightly drier than more typical swamps dominated by cypress and gum. Perhaps this landscape could best fit into his oak flats vegetation type. 3) Dorovan association: These are nearly level, very poorly drained soils that are dominantly muck throughout; on low-lying alluvial floodplains and in large undrained swamps. Natural Areas Represented: 1) Conaby Creek -Roanoke River 2) Bull's Neck Swamp Percentage of land area in county: 9% This landscape is restricted primarily to the Roanoke River basin and the Bull's Neck Swamp along Albemarle Sound. Minor areas occur along the Welch, Deep, and Mackey's Creek drainages and along the Scuppernong River. These wetlands are almost all below 5 feet in elevation and occupy deep peat or muck deposits in drainage basins. Because of their wetness, inaccessibility and flooding susceptibility, they have remained the least disturbed of the seven major soilscapes by drainage and clearing operations. The original vegetation probably consisted of baldcypress and swamp blackgum with scattered Atlantic white cedar, loblolly and 3 pone pines, sweetbay, redbay, and red maple. Today selective logging has removed most of the merchantable cypress, and much of the swamp is dominated by second -growth stands of gum and maple. Logging operations and associated roads and ditches constitute almost 100% of the disturbance to these areas, although some sand and gravel is being mined in parts of the Roanoke River basin. 4) Belhaven-Wasda-Roper Association: These are nearly level, very poorly drained soils that have a mucky surface layer and a dominantly loamy subsoil; on broad, level flats. Natural Areas Represented: 1) Van Swamp 2) East Dismal Swamp Percentage of land area of county: 25% This soilscape occupies much of what once was known as the East Dismal Swamp, an interior wetland which covered most of the county west of Lake Phelps. Up until fairly recently, most of the acreage was forested wetland. Difficulty of drainage, abundance of undecomposed cypress and cedar logs in the mucky soils, and lack of sufficient capital were the factors primarily responsible for thwarting development. All of this changed, however, in the 1950's and 1960's, when large capital investments combined with new draining and clearing tech- nology to open up these lands to agricultural development. Since that time the majority of the soilscape has been cleared, drained, and converted to corn and soybean production. Various blocks of natural vegetation persist in one form or another and two natural areas, Van Swamp and East Dismal Swamp, contain the best remaining examples of this once extensive wet- land ecosystem. The bulk of this landscape occurs in the central part of the county west and northwest of Lake Phelps. A smaller area lies in Van Swamp in the southwest corner. In general this association is surrounded on the north, west, and south by slightly higher, somewhat better drained mineral soils of the Cape Fear -Portsmouth -Roanoke association. To the east and southeast the mucky soils are bounded by a slightly higher "dome" of very deep peat, the Pungo association discussed next. The natural vegetation of the soilscape was probably originally dominated by great swamp forests of cypress, swamp blackgum, and 4 Atlantic white cedar. Numerous other wetland species were also present in varying proportions. Today, in the remaining forested areas, red maple and swamp blackgum predominate with sweetbay and redbay. The two natural areas contain the remaining mature second -growth and old - growth stands. 5) Pungo Association: These are nearly level, very poorly drained soils that are muck to a depth of 51 inches or more; on broad, level flats. Natural Areas Represented: Van Swamp Percentage of county land area: 7% This soilscape occupies almost the entire southeast corner of the county south of Lake Phelps. A small, disjunct area lies with- in Van Swamp in the county's southwest corner. This soilscape occupies the area of deepest peat accumulation, presumably along a filled -in paleo-channel of the Alligator River. About 8,000 yrs. before present, peat began filling in the former stream channel by vertical deposition, then began spreading over the adjacent landscape laterally. Eventually the mantle of peat spread out over most of central Washington County. The highest or deepest portion of this peat "dome" is the area occupied by the Pungo soilscape. The original vegetation was probably dominated by pond pine over a dense layer of evergreen and deciduous shrubs and bay trees. During extended droughts, the upper layers of the peat would dry out, and largescale wildfires occurred. Fire resistant species such as pond pine and the shrubs were better adapted to this fire -maintained regime and so dominated the landscape. This pond pine -dense shrub vegetation type overlying peat wetlands is the classical "pocosin." Because both Pungo and Phelps Lakes lie adjacent to the deep peat areas, it has been suggested that both formed as a result of peat fires which burned down to the underlying mineral layers. Enlargement of the burned areas occurred when water filled them and wind and water currents combined to erode the peat margins, gradually creating the large freshwater lakes which are present today. Recently, the potential use of peat as an alternative energy source has generated interest in mining the deep deposits. The southeast corner of the county was ditched and a series of access roads were constructed in the 1960's and 1970's. Peat mining on 5 an experimental basis was begun by First Colony Farms, a major land development corporation. Peat Methanol Associates has leased rights to First Colony Farms peat, and proposes to mine an area about the size of Lake Phelps, and immediately adjacent to that lake, over a 30-year period. Methanol from the peat will be exported to urban centers to the north. This ditching and road construction has altered what once was an excellent example of tall pond pine pocosin (high pocosin) and has degraded the natural integrity of the site. Present ditching and road construction activities in Van Swamp threaten to damage that area's significant natural features. The sixth and seventh Soil Associations, Dragston-Conetoe- Altavista and Conetoe-Wickham-Tarboro, occupy only a minor pro- portion of the county, totalling 60 of the land area. No natural areas were found on either Association, due to their limited extent and generally high agricultural productivity. Original vegetation probably consisted of mesic to somewhat xeric hardwoods, with lob - lolly pine and possibly some longleaf pine. Some of the more steeply sloping mesic sites supported herb assemblages more characteristic of Piedmont slopes. A few such sites were sampled during this sur- vey. Species such as bloodroot, indian cucumber root, mayapple, wild ginger, bellwort and others were present. OTHER VEGETATION COMMUNITIES In addition to the natural vegetation types just discussed, there are several other minor communities which exist in the county. Along the south shore of Lake Phelps is a narrow zone of fresh- water marsh. This marsh is described in the Pettigrew State Park natural areas site report. Small areas of freshwater marsh also occur at the mouth of Deep Creek along Albemarle Sound. Floating aquatic communities of cow -lily and water lily occur along the shallow water margins of Conaby Creek and the Roanoke River. The rest of the county is currently dominated by various agri- cultural and silvicultural lands. 0 Soils Hydroperiod Shrubs Pond Pines TABLE 1 SELECTED CHARACTERISTICS OF OTTE'S POCOSIN TYPES (from Otte, 1981) low high pond pine pond pine nocosin nocosin woodland forest greater than four two to four feet of one to two feet of peaty sand to one feet of peat peat peat or two feet of sandy peat abundant surface flooded in wet sea- flooded or saturated saturated in wet sea- water in wet season; son; water table in wet season but son; water table drops saturated year-round below surface but dropping to mineral into mineral sediments except in severe remains within or- layer in dry season in dry season drought ganic layer in dry season height is two to height is four to height six to fif- height ten to twenty four feet on moss eight feet; tallest teen feet; shrub feet; generally mats; four to six on hummocks; density layer usually closed feet on hummocks; is closed closed density of lower shrubs open; of taller shrubs closed height to ten feet; height to 25 feet; up to 60 feet tall mostly less than 50 trees widely scat- widely scattered and 2 feet dbh; feet tall, dbh to tered, gnarled scattered, less 12 inches; canopy than 50% cover generally closed MF.THnMMay The natural areas inventory of Washington County was under- taken to identify and describe the remaining sites within the county which contain significant natural values. The "study was carried out from December 1981 to September 1982 and utilized other data collected by various biologists familiar with the county. Study sites were selected by various reconnaissance methods. Most of the rural primary and secondary roads in the county were travelled in addition to many private logging and agricultural roads. A complete set of 1:24000 scale aerial orthophotoquad maps were examined along with 1:2000 scale black and white aerial photographs. Two low altitude aerial reconnaissance flights were conducted using a Cessna 172 fixed wing aircraft. Conversations with numerous people familiar with the natural lands of the county were also conducted. Foresters, soil scientists, land surveyers, sportsmen, farmers, and others with first-hand ex- perience were consulted. An attempt was made to accumulate all of the scientific liter- ature pertinent to the county's natural resources. After all the sources of information were gathered and evaluated, a number of potential natural area sites were identified for further study. A total of about 15 field days was spent visiting and in- ventorying each of the potential natural area sites. Natural areas were selected on the basic of several criteria. A primary factor used to assess an area's significance was the degree of past man -induced disturbances. Areas of old -growth timber which had been disturbed relatively little by previous logging cycles were given a high priority. The county was divided up into seven major,"soilscapes" or broad vegetation associations (see preceding section on Soils and Vegetation) and an attempt was made to identify and inventory an undisturbed example representative of each major soilscape. Emphasis was not on the unique or the un- usual. Rather, a representative example of all of the county's major vegetation or habitat types in an undisturbed, old -growth condition was sought for. Another important factor used in assessing a site's signifi- cance was its "wilderness" aspect. Large roadless or near roadless areas, while maybe not containing pristine habitats, were often con- sidered significant because of their inaccessibility and remoteness. Because areas with wilderness values are becoming increasingly rare in the N. C. coastal plain, it was felt this criteria was important in assessing a site's overall biological significance. 8 The value of a site for game and non -game wildlife habitat was also used as a selection criteria. An attempt was made to adequately survey the vertebrate faunal diversity of each site and make com- parisons with adjacent areas and other potential natural areas. In this way, the relative importance of an area for wildlife values could be determined. The diversity of habitats within the natural areas as well as the aerial extent of the site also entered into the evaluation. Large tracts containing a diversity of habitat types and allowing movement of large, wide -roaming mammals were given a higher priority over smaller, more restrictive and less diverse sites. As a result of this study, it is felt that all of the major large tracts containing significant natural areas have been iden- tified. Time and budget restraints prevented an adequate survey of all the small blocks of woodlands scattered in the county. It is possible that additional significant sites remain undiscovered in the remaining small tracts. Six significant natural areas were identified ranging in size from 149 acres to 6450 acres. These tracts cover a variety of edaphic and biotic habitat types ranging from mesic upland hard- woods to swamp forest and upland pocosin to freshwater lakeshore marsh. Each of the natural areas has been influenced in varying degrees by past and present cultural disturbances; however, it is felt these disturbances have not been severe enough to significantly reduce their biological integrity. All but one of these sites are exclusively wetland habitats. The six natural areas are: 1) Van Swamp: 2450 acres. Palustrine, non -alluvial swamp forest and pond pine pocosin. 2) East Dismal Swamp: 1630 acres. Palustrine, non - alluvial swamp forest. 3) Pettigrew State Park (2 natural areas) Total acreage: 250. Lakeshore baldcypress stand and freshwater marsh system. 4) Conaby Creek -Roanoke River: 3240 acres. Palustrine and riverine swamp forest associated with drainage basin. 5) Bull's Neck Swamp: 6450 areas. Palustrine swamp forest associated with drainage basin. 6) Chapel Swamp: 149 acres. Alluvial swamp forest and mesic upland hardwoods. 9 All of the described natural areas in Washington County, with the single exception of Pettigrew State Park, are privately owned. Lake Phelps, a 16,000-acre lake administered by the N.C. Division of Parks and Recreation, is not described in this report. A second natural area not described is the Pungo Lake National Wildlife Refuge. The 10,000 acre refuge contains the lake (2,800 acres) and adjacent altered pocosin and swamp forest lands. A research natural area containing 1,000 acres of low shrub pocosin vegetation is located on the east side of the lake. The primary natural value of the refuge is as a wildlife habitat, principally for wintering and migratory waterfowl. Portions of both Lake Phelps and Pungo. Lake Refuge are registered State Natural Heritage Areas. THREATS As discussed in several places in the following report, the original forests of the county have been entirely removed except for a few scattered remnant tracts or woodlots. The total acreage of the six natural areas represents only 14,169 acres, or about 6.50 of the total land area in the county. Large areas have been drained and cleared for agriculture, particularly within the past thirty years. Much of the re- maining area not devoted to row/crop agriculture is managed for loblolly pine production. The remaining natural lands are all threatened by eventual conversion to agricultural or silvicultural production. The only natural areas presently protected are located within the Pettigrew State Park at Lake Phelps. Both the Van Swamp and East Dismal Swamp natural areas, examples of a once extensive wetland swamp forest system, are in immediate danger of being permanently altered by timber interests. The Bull's Neck Swamp and Conaby Creek -Roanoke River natural areas are less seriously threatened at the present time. These two areas lie within extensive drainage basins, a factor which has impeded development. The Chapel Swamp natural area, which contains the only example of an upland forest type, is probably the least threatened of the privately owned natural areas. It is also the only one exclusively in family farm ownership. The others are wholly or substantially controlled by large corporations. Peat mining is an additional threat to the remaining swamp forest wetlands of the county, particularly those in Van Swamp. Much of southeastern Washington County, which once was an ex- tensive swamp forest and pocosin wetland, has been altered by clearing and drainage operations connected with peat mining operations underway there. 10 The future for the unprotected natural lands in the county looks bleak. Unless steps are taken immediately to insure their protection, the last remnants of the once great forests of the county will disappear forever. Along with the demise of the natural areas, species diversity will undoubtedly decrease. Mammals, birds, and other animals which depend on large tracts of relatively undisturbed forests will be replaced by other, more widespread species which are adapted to open farmland and other disturbed habitats. C MM17SION Washington County has undergone vast land use changes in its recent past. The opening up of the vast swamp forests and pocosins to agriculture has had a profound effect on all aspects of the county's development: economical, sociological, as well as en- vironmental. Despite these large-scale changes, there remain several tracts of land in the county which contain remnant ecosystems representative of the forested wetlands which once dominated the landscape. These remaining natural areas are described in the following report. The future for these sites is not bright. It is hoped that this report will generate some interest and enthusiasm, not only within the scientific com- munity but also among the residents of Washington County, so that these priceless remnants of our natural heritage can be saved and future generations will have the opportunity to see the closest approximation of the original Washington County landscape. 11 NATURAL AREA INVENTORY FORM (To be prepared for each site) Basic Information Summary Sheet 1.

Prose Description of Natural Area The Van Swamp natural area is a 2450-acre tract of swamp forest and pond pine pocosin wetlands located in southwestern Washington County. The natural area contains the last remnant stands of natural vegetation within the entire Van Swamp com- plex of Washington County. The original swamp system extended from near Plymouth in Washington County southwest to the com- munity of Pinetown, Beaufort County, a distance of roughly fifteen miles. Deforestation and conversion of the original swamp forest vegetation to managed pine plantations has re- duced the swamp to its present dimensions in extreme south- western Washington and adjacent Beaufort Counties (See Fig. 1) . Originally, Van Swamp occupied an area of about 13,440 acres in southwestern Washington County from Plymouth south to the Beaufort County line, a distance of about nine miles. Roughly rectangular in size and averaging 3-4 miles wide, Van Swamp was a sizeable wetland system with no well-defined drainage outlets. It was essentially a landlocked upland bog: a non -alluvial, palustrine wetland system. Today, a network of drainage ditches have tamed the swamp and most of the original swamp and pocosin vegetation has been cleared and converted to intensively managed pine plantations. What remains of the natural ecosystem is a small chunk in the south- western corner of the county. Geologically, Van Swamp is a relatively flat basin, bordered on its eastern and western mar- gins by two parallel, eastward -facing scarps. The older scarp along the western margin is known as the Pinetown scarp or Pinetown shoreline. The younger, topographically lower scarp on the east is called the Union Chapel shoreline (See Fig 2). Both of these scarps probably represent old beach ridges formed during periods of high sea levels during the Pleistocene Epoch (Mixon and Pilkey 1976). The area between the scarp, i.e., Van Swamp, consists of ancient beach ridges and back - dune flats. The elevation of the Van Swamp flat is generally between 30-40 feet msl. The tow of the Union Chapel Scarp is consistently 17-21 msl, whereas the toe of the Pinetown Scarp is about 38-40 feet msl (Mixon and Pilkey 1976). These two scarps are the dominant landforms in the area and are clearly visible on aerial photographs taken by the Apollo 9 spacecraft in 1969 (Mixon and Pilkey, 1976). The pro- nounced ridges along the crest of the scarps have effectively blocked the drainage of Van Swamp and as a result initiated the formation of the wetland system. In order to understand the ecological systems within the natural area, it is important that an overall picture of the { entire Van Swamp area be outlined. 14 The natural area contains the wettest, most poorly drained portion of Van Swamp. It also contains the only organic deposits deep enough to be mapped by soil scientists as histosols (peat soils) in the Washington County portion of Van Swamp. The rest of Van Swamp (outside the natural area) consists of poorly drained, wet, loamy or sandy mineral soils. The peat deposits began forming about 6000-8000 years ago when a small stream draining the swamp through a narrow break in the Union Chapel scarp became blocked. Drainage was impeded and a shallow body of water was im- pounded. The peat sediments accumulated both vertically and laterally, filling in the original channel and spreading out over the adjacent flats (Otte, pers. comm. 1982). Since that time.the peat has continued to accumulate and now has reached a depth of over 10 feet in places. It is easy to envision why the area underlain by these peat deposits has remained in a relatively natural con- dition while adjacent areas within the Van Swamp complex have been drastically altered. The better drained mineral soils of Van Swamp required relatively little investment in equipment and money and were easily converted using modern day technology to tree farms. The difficulty of draining the peat and the cost of site preparation ef- fectively stopped the tree farms at the margin of the peat fields. The peat however, did not exclude selective timber operations in this section from the early 1900's to the pre- sent day. Tramrodds were constructed and lumber was hauled out by rail. More recently several logging roads have been constructed and additional cutting undertaken. The natural area of Van Swamp is not pristine. All of it has been selectively timbered at least once within the past century. However, at least up to the present day, these disturbances have not seriously affected the natural hydrological and ecological processes which have been going on since pre -settlement times. The following paragraphs will describe the present day vegetation assemblages of the remnant Van Swamp wetland system. The N ssa sylvatica var. biflora/Acer rubrum/Persea borbonia community type (swamp black-gum/red maple/red bay); (CT 1) occurs in small, irregularly shaped patches through- out much of the natural area. This community is characterized by a canopy height ranging from 60-80 feet tall, an average canopy trunk diameter (above butt swell) of 14-17 inches, an estimated age of 75 + years, and a distinct three -tiered 15 stratification (canopy-subcanopy-tall shrub). On the best sites swamp black gum forms a closed canopy. Isolated large gums up to 32 inches dbh are scattered throughout the community along with several other species which reach the canopy but are not dominant: loblolly pine (Pinus taeda), bald cypress (Taxodium distichum), sweet - bay (Magnolia virginiana) , and Atlantic white cedar (Chamaecyparis thyoides). The subcanopy dominated by red maple also contains the tree species mentioned above. Redbay forms a dense tall shrub layer ranging from 10-25 feet in height. There is no dominant ground cover al- though species such as chain ferns (Woodwardia areolata, W. virginicd, sedges (Carex spp.), and royal fern (Osmunda regalis var. spectabilis) are scattered through- out. Vines are abundant in the community and include high - climbing species such as poison ivy (Rhus radicans), grape (Vitis sp.), laurel -leaved greenbriar (Smilax laurifolia) and yellow jessamine (Gelsemium sempervirens). During April when the yellow jessamine is in bloom, the flowers attract myriads of swallowtail butterflies including species such as palamedes, black, tiger, and spicebush. There are minor variations in species composition of the three layers. In some areas red maple does not form a dense subcanopy. In other places red maple and sweet - bay are co -dominants in the subcanopy. Truly large speci- mens of sweetbay are common throughout. Individuals of 10 inches dbh are common and some trees measure up to 14 inches dbh. Many are 60-75 feet tall. Sweet pepperbush (Clethra alnifolia) forms a locally dense low shrub layer, particu- larly along the canal banks where mineral spoil soils are exposed. The swamp blackgum stands represent the least dis- turbed sections of the swamp forest. Scattered very old stumps of Atlantic white cedar and cypress indicate the area was selectively timbered, probably during the early 1900's, a period during which many extensive logging oper- ations were underway in Washington County (Pat White, pers. comm., 1982). In those days, narrow gauge tramroads were built into the vast swamp areas and mostly high quality boles of cypress and cedar were removed. Today, large cull trees of deformed cypress and cedar remain in the swamp. Some cull cypress trees are up to 4 feet in di- ameter and over 100 feet tall. Probably the original swamp forest vegetation type of Van Swamp was cypress/ swamp blackgum-Atlantic white cedar. Early descriptions of cypress -dominated swamp forests are common in the literature (Pinchot and Ashe, 1897; Ashe, 1894). 16 The second swamp forest community type (CT 2) in the natural area is Pinus taeda-Nyssa sylvatica var. biflora/ Acer rubrum/Persea borbonia (loblolly pine -swamp blackgum/ red maple/redbay). This community is characterized by a canopy height of between 65-85 feet, an average canopy tree dbh of 12-14 inches, and an age estimated to be between 50-75 years old. It is similar in many respects to CT 1, discussed in the preceding paragraphs. Common trees in the canopy (but not dominant) include Atlantic white cedar, sweet - bay, cypress, and tulip poplar (Liriodendron tulipifera). Common subcanopy and shrub layer species include the above trees in transgressive age classes plus sweet pepperbush and fetterbush (Lyonia lucida). As in CT 1, vines are abundant and include poison ivy, yellow jessamine, and laurel -leaved greenbriar. Topographically and pedologically, this community appears to occupy the same areas as CT 1. The major difference between these communities, i.e., the dominance of loblolly pine in the canopy, is probably partly attributable to timber operations in the recent past. The smaller trunk diameters, partly open canopy cover, and greater variability of canopy and subcanopy heights indicate a wider range of age classes and a higher proportion of younger trees when compared with the vegetation structure of CT 1. This is particularly evident in certain section of the swamp where more recently cut stumps are pre- sent. However, some portions of the natural area, particularly in the corner north of SR 1101, contain many large, flattop old -growth pines and appear to be relatively undisturbed. This may be explained by a greater abundance of sandy mineral horizons close to the surface, a situation which is more favorable for loblolly pine germination and growth. Ashe (1915, P. 10) states that loblolly pine in the original forests of the coastal plain occurred among other places, in "... shallow interior swamps with loamy soils among maple, water oaks, and gums ... and in deep swamps in which it was not common and where it occurred with cypress, water gum, and water ash." The third community type (CT 3) represented in the natural area is Pinus serotina/mixed pocosin shrubs//Smilax laurifolia (pond pine/mixed pocosin shrubs//laurel-leaved greenbriar). This community is characterized by an open canopy of scattered pond pines 60-90 feet tall over a very dense tall shrub layer composes of a number of typical pocosin shrubs and small trees such as loblolly bay (Gordonia lasianthus), sweetbay, redbay, fetterbush, sweet gallberry (Ilex coriacea), and red maple. The shrub layer is inter- twined by dense tangles of laurel -leaved greenbriar. Several very large specimens of loblolly bay were seen during the course of the field work. One clump of trees was about 70 feet tall with one specimen measuring 27 inches in diameter. 17 This community is typical of many pond pine -evergreen shrub associations overlying deep peat areas in the eastern coastal plain of North Carolina. They are quite distinct, both structurally and floristically, from swamp forests which are usually dominated by combinations of swamp black - gum, cypress, and Atlantic white cedar. Vegetation of the evergreen sh xub bogs or pocosins have been described else- where in the literature (Kologiski, 1977; Wells, 1942; Wells, 1967). Most botanists agree that the evergreen shrub bogs or pocosins are 1) usually over moderate to deep peat layers; 2) have seasonal high water tables at or near the surface; 3) are almost always associated with non -alluvial, upland basins and interstream divides; 4) mostly are the result of blocked drainages with the major exception of carolina bays, and 5) are dominated by a diversity of fire resistant woody shrubs and usually containing at least a few scattered pond pines. The Van Swamp pond pine pocosin appears to be highly correlated with a particular soil series, Pungo muck (dysic, thermic Typic Medisaprists). This peat soil is characterized by upper organic horizons from 51 to more than 90 inches thick underlain by clayey mineral horizons. The seasonal water table is at or near the surface throughout much of the year. These soils differ from Belhaven muck in having much thicker organic layers (4-10 feet in depth). Recently, Otte (1981) has described a number of interrelated processes which he believes account for the distribution of pond pine pocosin in the peat dominated wet- lands of the coastal plain. He concludes that an important factor concerning the maintenance of pocosins is dizection of water flow. "Swamp forest peat (based on a number of samples) contains a higher average mineral content than does pocosin peat. This sediment is carried into the wetlands by surface runoff from the surrounding uplands. This runoff most likely also carries dis- solved nutrients that would not be available to a system fed primarily by precipitation (i.e., pocosins)." He contends that if surface runoff from adjacent highlands flows part -way into a peat -dominated wetland, but not all the way through, the outer margins of the wetland most likely would develop into swamp forest and the sediment -free, nutrient - deprived inner portions would likely develop pocosin vegetation. In Van Swamp the distribution of the pond pine pocosin seems to support this hypothesis. The pocosin vegetation occurs in a zone of very deep peat (mapped as Pungo muck) located in the east -central portion of the swamp. Shallower peat areas on either side of the pocosin are dominated by 18 %a �w Boa„Shf ..�+• / f 7• .\l Pow. 4T74 L, ` jl ,,yP �+• I��s fro r.

These margins probably receive a degree of sediment deposition from the adjacent mineral soils along the scarps. The deep peat "dome" in the center of Van Swamp receives little, if any, nutrient imput (other than that derived from precipitation). The thickness of the peat in this area may also inhibit nutrient uptake of plants due to their inability to reach underlying mineral layers. Man -induced disturbances such as intensive clearcutting and frequent wildfires can create pocosins from what originally was swamp forest (Otte, 1981). The timber cutting history of Van Swamp is not well-known and the question of whether the pond pine pocosin now present is a natural system or one created by past disturbances is open to debate. However, a comparison between the pond pine pocosin , vegetation and the distribution of deep peat can be made by reviewing Figs 3 and 4 . There is a high correl- ation of the distribution of the pond pine pocosin with the deeper peat deposits. The natural area provides an excellent opportunity to study the relationship between vegetation and the underlying soils, and the effects of sediment and nutrient recycling on vegetation systems. Finally, the wildlife values of the Van Swamp natural area should be mentioned. According to McClanahan (North Carolina Wildlife Resources Commission District Biologist, pers. comm. 1982), the Van Swamp area supports one of the largest and healthiest whitetail deer herds in Washington County. Scat and tracks are abundant along the roads throughout the natural area. A remnant black bear popu- lation is still present (a fresh set of tracks were seen near SR 1101). However, it is questionable whether enough habitat is available to support a viable breeding population. Bobcat, uncommon in many areas of the state, are also present within the swamp. Breeding bird diversity within the swamp is excellent for a coastal plain forest system; 43 species of breeding birds were recorded within the natural area in- cluding several species which are uncommon and local in the coastal plain and which are restricted to non -alluvial swamp and pocosin wetlands. Black -throated green and worm -eating warblers were recorded including the largest population of the former recorded anywhere in the county. Both species are probably decreasing in the coastal plain as a result of habitat destruction. Other species present which re- quire large wetland acreages and mature timber stands in- cluded the pileated woodpecker and the red -shouldered hawk, the latter considered threatened in the state (Cooper, et al, 1977) . 20 The breeding bird diversity is all the more remarkable considering the general homogeneity of the swamp forest stands, a minimal amount of edge effect and the complete absence of open water or terrestrial habitats. Probably no other area in Washington County of comparable size and ecological uniformity contains a comparable diversity of b 3neding birds. 21 llb. Prose Description of Site Significance: Van Swamp contains some of the finest remaining old - growth stands of swamp blackgum known in eastern North Carolina. Few examples of old -growth stands associated with a peat -dominated, palustrine wetland system are known in the state. The swamp also contains some of the largest specimens of sweetbay and loblolly bay seen by the authors anywhere in the state. Trees of "state champion" stature are present in the natural area. Van Swamp also contains a representative example of a pond pine pocosin vegetation type associated with a deposit of deep peat. The natural area illustrates the relationship of vegetation and peat soils with contiguous examples of both swamp forest and pond pine pocosin vege- tation types, both in a relatively undisturbed condition. The 2450-acre natural area is the last remnant of natural vegetation in Van Swamp, a wetland system which once encompassed over 13,000 acres before drainage and clearing operations reduced it to its present size. As a forested wetland ecosystem, the natural area functions as an important refuge for many wildlife species, including white-tailed deer, black bear, bobcat, and other furbearers. The site supports one of the largest deer herds in the county and also contains a small,remnant black bear population, a species which is much reduced in numbers throughout the coastal plain due to habitat destruction. Avian diversity is considered to be excel- lent for a coastal plain forest wetland. Forty-three species of breeding birds have thus far been recorded, including ten species of wood warblers. Two of those, the Black -throated green and worm -eating warblers, are uncommon and local breeders in the coastal plain. 22 N w 12.

Uses of natural area: The portion of the natural area owned by Georgia-Pacific Corporation is open to public hunting under the N. C. Wildlife Resources Commission's Gamelands program. Deer hunting is the primary activity. The area has been timbered periodically since historical times and is presently undergoing a considerable amount of logging. Almost all of Van Swamp north of SR 1101 has been ditches, drained and converted to intensive loblolly pine silviculture. The wetter portions of the swamp south of SR 1101 (underlain by the deepest peat deposits) contain the last remnants of natural swamp vegetation although this area is presently being ditched, apparently with the intent of conversion to pine planta- tion. 19, Uses of surrounding land: a.

The finest remaining relatively undisturbed swamp forest timber is being cut at the present time. Clearcutting is converting former hardwood swamp forest to managed loblolly pine plantations. Extensive ditching and draining operations in the wettest areas of the swamp are undoubtedly going to result in better drained conditions, alteration of the natural hydrological patterns, in- creased edge effect and the possibility of fire, and in general alter the natural qualities of the swamp. 23. Management and Preservation Recommendation: Drainage and cutting must be curtailed if any portion of the natural area is to be preserved in its natural state. Construction of lateral ditches presently being dug should cease. Water control devices will have to be built on the main ditches to control gravity flow of water out of the swamp and to simulate the more natural high water table conditions. The site should be proposed for inclusion in the Society of American Foresters' Natural Areas program as an excel- lent mature example of Forest type No. 104 -- Sweetbay-Swamp Blackgum - Red Maple. 30 Natural Characteristics Summar 24a.

Prose Description of Site: INTRODUCTION .The East Dismal Swamp Natural Area is a 1630-acre tract containing a mixture of bottomland hardwoods and swamp forest vegetation situated on a poorly drained upland flat along the western margin of the Pamlico Terrace. The natural area con- tains the best remaining example in Washington County of re- latively undisturbed natural vegetation within the once vast upland swamp and pocosin wetland complex known as the East Dismal Swamp. It should be noted here that the natural area was dis- covered at a rather late date during the course of field work. Consequently, the authors were unable to survey the vegetation communities and other biological aspects of the site with the same amount of time and detail other natural areas received. However, an initial assessment of the site's ecological sig- nificance was determined, based on observations made during a single site visit. The conclusion is that the site is of medium to high significance due to the relatively undisturbed, old -growth condition_ of the plant community and its status as the only known well-preserved example of a swamp forest eco- system remaining in the East Dismal Swamp. Further field work is urgently needed to document and substantiate the significance of the site which, based on preliminary obser- vations, appears to have countywide or regional significance. Pre-1950 topographic maps show the East Dismal Swamp covering almost all of Washington County from Lakes Phelps and Pungo west to the Union Chapel Scarp (N. C. Highway 32), and from U. S. Highway 64 south into Beaufort County. During the 1950's much of this swamp was drained, cleared, and converted to agricultural production by "super -farm" cor- porations. The remaining small blocks of wooded land have either been drained and converted to pine plantations by the timber industry or have been almost completely cut -over, leaving a heavily disturbed woodland bearing little, if any, resemblance to the swamp forest wetland system which once covered this region. The original extent of the East Dismal Swamp in Washington County alone is estimated to have comprised at least 70,000 acres. This figure is based on the wetland soil acreage de- rived from the county's general soils map (SCS 1981). Using 45 this figure, the natural area represents less than 3% of the original East Dismal Swamp wetland system, a miniscule rem- nant of the swamp forest and pocosin vegetation types which once dominated much of the Washington County landscape. The East Dismal Swamp natural area is situated on a broad, very flat, upland surface which is poorly drained due to the lack of stream drainages in the area. Elevation ranges from 16-18 feet above sea level. Topographically, the site is located on an upland, interstream flat. To the north and east, several minor tributaries drain the margins of the flat. Areas to the south and west of the natural area are drained by a series of interconnecting ditches and canals which drain eventually into the Pungo River. The natural area is situated on the Pamlico Terrace, the land surface containing surficial sediments deposited about 100,000 years B.P. when sea level was much higher and the Atlantic Ocean covered much of the outer coastal plain (Ingram and Otte 1982). About 18,000 years ago sea level was about 400 feet below present sea level during which time the Pamlico Terrace was dissected by stream erosion resulting in a dendritic pattern of stream valleys. Since that time sea level has been rising. About 10,000 years ago peat development began in shallow lakes and marshes along the stream courses. These blocked channels filled with peat and began flooding the adjacent low-lying areas. This flooding created a large, flat wetland on which a swamp forest became established and in which the decomposing vegetation eventually formed the organic soils covering much of East Dismal Swamp (op. cit. 1982). This blanket of organic deposits occupies the flat, poorly drained surface within the natural area. Almost the entire natural area has been mapped as the Belhaven muck soil series, a relatively shallow organic soil which has organic accumulations 16-51 inches thick. These shallow peats are a western extension of a much larger body of peat which lies adjacent to the southwestern and southern sides of Lake Phelps, about 6 miles SE of the natural area (op cit 1982). VEGETATION The natural area is dominated by an interesting assemblage of bottomland hardwoods and typical swamp forest species. One community type was determined from field observations: Nyssa sylvatica var. biflora/Acer rubrum-Magnolia virginiana/Persea borbonia (swamp blackgum/red maple-sweetbay/redbay; CT 1). 46 This community is characterized by an open to partially closed canopy 70-80 feet tall, average trunk diameters of 18-22 inches, and a distinct three -tiered stratification: canopy-subcanopy - tall shrub. Much of the area is dominated by swamp blackgum although locally, tulip poplar (Liriodendron tulipifera) is a common canopy constituent. Extremely large specimens of the latter tree are common, ranging in size up to 90 feet tall with dbh's of 24-36 inches. Also present in the canopy are occasional large loblolly pine (Pinus taeda) and baldcypress (Taxodium distichum). The subcanopy is composed of very large sweetbay along with red maple. Occasional scattered clumps or indi- viduals of Atlantic white cedar (Chamaecyparis thyoides) are present in this layer. Most of the cedars appear to be mature or old -growth in age. A dense tall shrub layer dominated by redbay is ubiquitous throughout the tract. There are no distinct low shrub or ground layers. Common species present in these layers include sweet pepperbush (Clethra alnifolia), highbush blueberry (Vaccinium corymbosum), and royal fern (Osmunda regalis var. spectabilis). Vines are conspicuous and abundant in all the vegetation layers. The most common species are climbing hydrangea (Decumaria Barbara), _ yellow jessamine (Gelsemium sempervirens), and Virginia creeper (Parthenocissus quinquefolia). Other minor plant communities may be present within the natural area. Time restraints and the late discovery of the site prevented a more thorough examination. Some portions of the tract appear to be more recently disturbed by selective timber cutting. These areas have a greater proportion of red maple and loblolly pine in the canopy than the least disturbed, old -growth sections. Unusually large specimens of several canopy and subcanopy components deserve mention. Scattered old -growth swamp black - gums are present with trunk diameters in excess of 30 inches. As in the Van Swamp natural area (see pp. ), sweetbay reaches an impressive size with many trees present which are in the 13-15 inch dbh range (maximum dbh = 18 inches) and with heights up to 75-80 feet. Scattered old -growth baldcypress are present as emergent "flattops", reaching 62 inches dbh and 100 feet in height. These old giants are probably "cull" trees left over from past logging operations due to trunk deformities and other defects. Old -growth, flattop loblolly pines are also present. Tulip poplars, mentioned earlier in the text, reach an impressive size. They, too, appear to be old -growth "cull" trees which re- main intact from earlier logging cycles. Apparently, early logging operation methods focused on the removal of the highest quality 47 timber, and often left smaller or deformed specimens of highly desirable species such as cypress, white cedar, and tulip -poplar remaining in the forest stands. This practice, known as high -grading, eventually reduced the dominance of baldcypress and Atlantic white cedar in the swamp forest stands, while at the same time increasing the dominance of swamp blackgum, red maple, and other less valuable timber species. The natural area contains a fairly sizable population of tall pawpaw (Asimina triloba), a tall shrub which usually is found on rich alluvium on second -bottoms and slopes along brownwater rivers and streams. Pawpaw also occurs in mesic hardwood stands in the coastal plain but almost always on mineral soils. In the natural area the species occurs on shallow peats which have underlying mineral horizons. Paw- paw is not known to occur on peat soils anywhere else in North Carolina. Its occurrence in the natural area would not be predicted based on its known habitat associations. The presence of tulip -poplar on peat soils is not generally well-known although it is mentioned in the literature. It is not known to be a dominant canopy tree in coastal plain wetlands. It usually occurs on moist mineral soils, particularly on sandy loams which are well -drained. Concerning its occurrence in the Pamli- marle Peninsula, Ashe (1894) writes: "Much of the swamp in Washington and Tyrrell Counties is thinly timbered with the savanna (pond) pine. There is a great deal of soft maple and yellow poplar scattered throughout the swamp ... Lumbering has been one of the leading industries of these counties for a great many years, the numerous canals and streams which penetrate the region affording great facilities for removing timber." Ashe (op cit) mentions tulip -poplar in descriptions of swamp forests in other coastal plain counties and notes its occur- rence along with bald -cypress and swamp blackgum. The presence of old -growth tulip -poplar along with bald - cypress, swamp blackgum, and Atlantic white cedar within the natural area probably represents an aggregation of spe- cies which, at least until modern times, was fairly typical 48 of upland swamp forests overlying peaty mineral or shallow organic soils. Examples of this aggregation containing old -growth timber are not known anywhere else in the county at the present time. Other natural areas in the county, such as Van Swamp, which contain similar upland swamp forests do not contain old -growth tulip -poplar, presumably because past logging activities have removed all standing timber and regeneration has not occurred. WILDLIFE AND AVIAN DIVERSITY The wildlife values of the natural area are probably sig- nificant. However, the discovery of the area during the latter stage of field work prevented a thorough inventory of the fauna, and many species particularly birds, were undoubtedly missed. Abundant tracks of white-tailed deer were present throughout and several eastern gray squirrels were observed. Habitat appears to be highly suitable for breeding black -throated green warblers, an uncommon and local coastal plain species. Due to the late date none were recorded. Black bear and bob- cat, although no sign of either was recorded, probably occur as either residents or as occasional visitors. The natural area, surrounded on three sides by square miles of cleared land, probably serves as an important woodland sanctu- ary for many game and non -game species, particularly those species characteristic of forested wetland systems. Hopefully, further field work will shed more light on the importance of the tract as habitat for wildlife species. 49 llb. Prose Description of Site Significance: The East Dismal Swamp Natural Area contains the last known remnant of mature, old -growth swamp forest vegetation remaining in a once extensive palustrine, peat -dominated wetland system which formerly covered over 70,000 acres of central and southern Washington County. The tract con- tains unusually large specimens of the swamp forest trees characteristic of the non -alluvial, "upland" wetlands associated with poorly drained peat or peaty mineral soils. Tulip -poplar, swamp blackgum, baldcypress, Atlantic white cedar, and loblolly pine are all present in what probably most closely resembles the original composition of the swamp vegetation before timber exploitation began. The once vast East Dismal Swamp has been almost com- pletely cleared of its swamp forest and converted to agricultural fields or managed tree farms. The natural area is the last known relatively undisturbed remnant of that wetland system remaining in the county. 50 Ln H 12.

Easily accessible to hunters, the site is bisected by several well -maintained, graded dirt roads which are apparently never gated. It is likely that the corporation which owns the natural area and much of the adjacent lands leases the hunting rights to a local gun club, a common practice in eastern North Carolina. Timbering activities have up to the present time been limited to low -intensity selective cutting. Old -growth stands along Wash- ington Avenue and Sherrill Road in the southern portion of the natural area have apparently not been timbered at all within the past 50-75 years. In this area cutting was probably limited to baldcypress and Atlantic white cedar, old stumps of which are present. Other sections appear to have undergone some moderate selective thinning, although there is not evidence of cutting within the past ten years or so. Outside the natural area boundaries, timber cutting has been both extensive and often intensive. Large tracts have been ditched, cleared, burned and reseeded in loblolly pine tree farms. Much of this activity appears to have taken place within the past ten years. Other stands have been high -graded repeatedly and now contain stands of young and medium -growth red maple, sweetgum, and loblolly pine. Ditching and drainage of these adjacent forests is a continuing practice; evidently as preparation for eventual conversion to intensively managed pine plantations. It should also be noted that a series of parallel lateral ditches about 700 feet apart have also been constructed in parts of the natural area. These ditches were built about ten years ago but were allowed to grow up and are now barely visible. Apparently at one time the timber company planned to drain and clearcut the site. Why this has not been done is not known. Possible reasons for the delay could be the difficulty of managing peat soils or unfavorable economic conditions. 19, Uses of surrounding land: a.

As mentioned in the preceding section, much of the land surrounding the site has been or is in the process of being drained and converted to loblolly pine plan- tations. The first stage in the conversion of swamp forest timber to managed pine plantation is the development of ade- quate drainage, i.e., construction of drainage ditches and canals. This stage has apparently been completed within the natural area as evidenced by a well -integrated series of lateral ditches. The next step involves clearing the vege- tation and bulldozing stumps and logs into windrows to be subsequently burned. It is probably a matter of only a few years before this next stage of site preparation is imple- mented in the natural area. 23. Management and Preservation Recommendation: It is highly recommended that the natural area be recog- nized as having superlative values as an endangered wetland system and be protected as an example of an old -growth swamp forest remnant of the once vast East Dismal Swamp complex. The timber company which owns the tract should be contacted and informed of the site's natural significance. The site is an excellent candidate for inclusion in the Society of American Forester's Natural Areas program which seeks to identify and protect examples of relatively undisturbed, mature stands of all the major forest types in the United States. The site could also be included on the N.C. Natural Heritage Program's Registry of Natural Heritage Areas as an excellent example of a swamp forest wetland containing sig- nificant aspects of the state's natural heritage. Steps should be taken immediately to address both of these options. Management of the site should be minimal. Access re- striction could be implemented with the addition of several gates. Agreements could be arranged for wildlife officers to periodically patrol the area to enforce state and local game laws. 55 Natural Characteristics Summar 24a.

Prose Description of Site The Pettigrew State Park Natural Areas are located on the northern and southern shores of Lake Phelps, a 16,000 acre natural lake, the second largest in North Carolina. Pettigrew State Park and Lake Phelps, both administered by the N.C. Division of Parks and Recreation, encompass the entire lake acreage below the mean high water line, in addition to two upland tracts along the northern and southern margins containing 270 and 500 acres, respectively. Lake Phelps is the dominating landform of the region. Elliptical in shape, it is located in southeastern Washington County with a small portion of its extreme eastern edge in Tyrrell County. The lake averages about 5 feet in depth and has a shallow, sandy bottom except in the northern and eastern portions where wind and water -borne silt and fine peat sediments have accumulated. The origin on Lake Phelps is unknown although several theories exist. One is that the lake is an example of a carolina bay, an elliptical depression with a NW -SE orientation and usually with a sand rim along the southeastern margin. Another theory is that Lake Phelps was formed by a peat fire which burned down to the underlying mineral layers during a severe drought below the normal water table. The depression thus formed eventually filled in with water. Later, wind and wave erosion helped to en- large the lake, smooth out the margins, and create the el- liptical shape (Otte, pers. comm. 1982). Whatever its origin, Lake Phelps is unique compared to the similar Pungo and Alligator (New) lakes to the south. These latter two lakes do not have a sandy bottom and are totally rimmed by deep peat deposits. They are also much more depauperate both floristically and faunistically, con- taining very small fish populations and little if any emergent marsh vegetation. Lake Phelps, on the other hand, supports a large population of both game and non -game fish, including the state endangered Waccamaw Killifish (N. C. Department of Natural Resources and Community Development, 1977). A number of swans, geese, and ducks use the lake for feeding and roosting during the winter months. The lake also supports a remnant old -growth stand of baldcypress along its north shore and a unique emergent and submergent marsh system along its southern shore. These two vegetation types are of statewide significance and are dis- cussed in detail in the following pages. 64 North Shore Baldcypress Stand This natural area is located along the north shore of Lake Phelps between the park headquarters on the east and the park boundary along Moccasin Canal on the west. State Road 1166 runs along part of the northern edge of the natural area. The 180-acre tract is very narrow and linear in shape, ranging from 350 to about 1300 feet wide, and is parallel to a three-mile section of the north shoreline. The boundaries of the natural area follow the park boundary on the north and the open water of the lake to the south. The vegetation of the natural area is composed of an old - growth stand of very large trees dominated by baldcypress. The community type is Taxodium distichum/Asimina triloba/mixed herbs and ferns (baldcypress/tall pawpaw/mixed herbs and ferns; CT 1). This community also contains scattered tulip -poplar (Liriodendron tulipifera), sweetgum (Liquidambar styraciflua), and American elm (U1 mus americana) in the canopy. The closed canopy averages about 90-100 feet in height. A distinct closed shrub layer dominated by tall pawpaw, 10-30 feet tall, is located under- neath. There is a 75-100% ground cover composed of various species of herbs and ferns. Most common species are Japanese honeysuckle (Lonicera japonica), jewelweed (Impatiens capensis), fa.se nettle (Boehmeria cylindrica), and Southern lady fern (Athyrium asplenioides). High -climbing vines are abundant and include species such as poison ivy (Rhus radicans), Virginia creeper (Parthenocissus quinquefolia), cross -vine (Anisostichus capreolata), trumpet creeper (Camp sis radicans), wild grape (Vitis sp.), and rattan -vine (Berchemia scandens). The sheer size of the baldcypress and other canopy trees is very impressive. Baldcypress average about 50 inches in diameter at breast height (dbh) with many trees exceeding 100 feet. The maximum dbh and height recorded is 76 inches and 120 feet, respectively. Sweetgum, tulip -poplar, and American elm also reach outstanding size. Average dbh values for the three species respectively are: 39, 27, and 21 inches. Tall pawpaw, usually a small to medium sized shrub, reaches a height of about 30 feet with dbh's better than 7 inches in the natural area. Although no tree cores were taken, the age of the bald - cypress is estimated to be close to 300 years (Department of Natural Resources and Community Development, 1977). The baldcypress stand (CT 1) is situated on Fortescue mucky loam, a very poorly drained soil limited in the county to narrow, slightly elevated rims along the northern and northwestern sides of Lake Phelps. This soil is characterized by an upper layer of mucky or silty clay loam about 21 inches 65 thick over a layer of muck. The upper layer of mineral soils was probably deposited by lake -borne sediments at a time when the lake level was higher than it is currently. There are several distinct differences in the vegetation as one moves across a transect taken from the park boundary (inward side) to the open water along the lake shore. The community just described reaches its best development in terms of tree size and structural zonation on the inward (upland) side of the natural area, i.e., the side most distant from the lake. This section is the best drained portion of the natural area and is not flooded by lake waters except possibly during severe storms such as hurri- canes. The percentage of sweetgum and tulip -poplar is highest in this section. Also the pawpaw and ground cover layers are best developed here. As one moves towards the lake, the bald - cypress become smaller, both in trunk diameter and in height, and the relative proportions of sweetgum and tulip -poplar be- come lower. Swamp blackgum (Nyssa sylvatica var. biflora) becomes more common in the canopy. Pawpaw thins out and is replaced by more flood tolerant shrubs such as Virginia willow (Itea virginica), elderberry (Sambucus canadensis), and button - bush (Cephalanthus occidentalis). The herb layer is dominated by moisture tolerant species such as tear -thumb (Polygonum sagittaefolium), jewelweed, and false nettle. Smaller stands of baldcypress extend out into the shallow waters of the lake. Here, in a more or less permanently flooded situation, they are the sole canopy species with no underlying shrub or herb layer present. Evidence that the water level of the lake has fluctuated in the past is reflected by the distinct age classes of the baldcypress which become successively younger towards the open water of the lake. The cypress fringe along the lake shore is characterized from the old -growth stand (CT 1) by younger trees of smaller stature, lack of a distinct closed shrub layer (and absence of pawpaw), and the presence of a very dense herbaceous ground cover. This vegetation type is sufficiently distinct to be designated as a community: Taxodium distichum/Boehmeria cylindrica-Impatiens capensis (Baldcypress/false nettle -jewel- weed). It is not considered to have a significance value which warrants its mention in the significance summary or biotic sum- mary table, however. Many wildlife species utilize the baldcypress stand (CT 1) for nesting, feeding and cover. At least 39 species of breeding birds are known to occur in the cypress stand itself and an additional 35 species use the lake and the surrounding farm- 66 lands during the winter months and in migration. Mammals known to occur in the cypress stand include resident opossum, raccoon, eastern gray squirrel, marsh rabbit, and white-tailed deer. Black bear pass through the area on rare occasions, wandering from the large poco- sin south of the lake. The large trees provide numerous cavities for denning and the dense shrubs provide important songbird feeding and nesting habitat. The area is also important because it is the last remaining densely wooded shoreline along the lake, the remainder of which has been cleared for agriculture or residential home development, or disturbed by logging activities and frequent fires. South Shore Marsh The second natural area within Pettigrew State Park is located along the southern margin of Lake Phelps. This natural area contains a freshwater marsh which occupies a narrow band 60-150 wide along the shore line and the shallow (less than 18 inches deep) margin of the lake. The plant community occurs on clean, quartz sands in shallow water. It is dominated by the community Panicum hemitomon-mixed aquatic herbs (Maidencane/mixed aquatic herbs; CT 2). Along with maidencane (an emergent marsh plant), other common aquatics include water milfoil (Myriophyllum tenellum), pickerelweed (Pontederia cordata), three -square (Scirpus americanus), pennywort (Hydrocotyle umbellata), pipewort (Eriocaulon pel- lucidum), duck potato (Sagittaria teres or isoctiformis), and needlerush (Juncus sp.). Species such as Pontederia, Errocaulon, Sagittaria and others usually occur in loose clumps and scattered individuals adjacent to the dense maidencane mats. Differences in water depth, substrate, and availability of sunlight are im- portant factors which determine the spatial arrangements of the various species. Maidencane, because of its size (2-3 feet) and dense stem development, often forms almost pure beds at the exclusion of other, much smaller aquatics. This 70-acre freshwater marsh community is restricted to the southern perimeter of the lake which is sheltered from the predominantly southwesterly winds. This marsh community is unique in the state because of its unusual species composition. Myriophyllum tenellum, for example, is a species of water mil - foil which grows in dense submerged mats. It is not known to 67 occur elsewhere in the state and the Lake Phelps site represents the southernmost occurrence in its range which extends through the New England states into the Maritime Provinces (Aiken 1981). Both Eriocaulon pellucidum and Sagittaria sp. (teres or isoetiformis) are listed as significantly rare plants in North Carolina and are known in the state from only a few scattered localities (N. C. Plant Protection Program, 1982, Cooper et al, 1977). The Sagittaria, because of an unclear taxonomic status, has not been determined to species as of this writing. The marsh vegetation along the south shore is a significant breeding area for many of the game and non -game fish living in the lake. The state endangered Waccamaw Killifish is known to occur on earth only from Lakes Waccamaw and Phelps (Cooper et al, 1977). The specimens at Lake Phelps have been found to differ slightly from the Lake Waccamaw specimens in some respects. This slight differentiation in the two disjunct populations tends to lessen the possibility that the Waccamaw Killifish was accidentally introduced by man into Lake Phelps (Lindquist and Yarbrough 1981). Habitat for the Killifish is reported to be shallow, sandy shores vegetated with dense stands of Panicum hemitomon (op. cit. 1981). The natural area in all likelihood provides critical habitat for this endangered fish. The marsh is not dense enough to provide suitable nesting and feeding cover for marsh birds, although some species such as bitterns, rails, and herons, undoubtedly use the area during migration. 68 llb. Prose Description of Site Significance: The Pettigrew State Park natural areas described in this re- port contain unique community types unknown elsewhere in North Carolina. The Baldcypress/pawpaw/mixed herbs community (CT 1) along the north shore is highly significant for several reasons. It contains some of the largest trees known from the entire Pamlimarle Peninsula, both in terms of overall height (many trees are in excess of 100 feet) and in trunk diameter (average dbh is about 50 inches). There are no other stands known in Washington County which compare in age and stature. The pre- sence of pawpaw as a dominant shrub species in association with cypress is not known to occur elsewhere in the state. Pawpaw is more typical of stream and river floodplains of the piedmont and upper coastal plain and is relatively rare in the outer coastal plain region of the state. The Maidencane-mixed aquatic herbs freshwater marsh com- munity (CT 2) along the south shore of the lake is also unique in North Carolina. No other freshwater marshes are known which contain this assortment of emergent and submergent species. The freshwater marsh community also contains a species of water milfoil, Myriophyllum tenellum, which is not known any- where else in the state and which reaches its southernmost occurrence here. It is more typical of marshes in the Canadian Maritime Provinces and the New England states. Also present are two other plants considered to be significantly rare in the state - Eriocaulon pellucidum, and Sagittaria sp. (teres or isoetiformis). Both species are known from only a few scattered localities in North Carolina. Also present within the lake itself and probably dependent on the marsh community for feeding/breeding habitat is a state endangered endemic fish, the Waccamaw Killifish. This species is known to occur in the world only in Lakes Waccamaw and Phelps (Cooper et al, 1977). Lake Phelps is the second largest natural lake in North Carolina. The natural areas along its northern and southern shores contain unique plant communities and rare species which are of statewide significance and represent remnants of two lake shore ecosystems which are integral parts of the overall Lake Phelps biological systems. 69 J O North Shore Baldcypress Stand 12.

Attitude of owner or custodian toward preservation (contacted?): The North Shore Baldcypress Stand is protected as a state natural area within the Pettigrew State Park. It is also recognized as a State Natural Heritage area by the N.C. Natural Heritage Program. The South Shore Freshwater Marsh is within park boundaries but is not officially recognized as a natural area. 75 18. Uses of natural area: The lake itself is used for a variety of recreational activities, including boating, sailing, fishing, and skiing. The north shore cypress stand is occasionally used by park hikers. Development of the western and southwestern margins of the lake for residential homes is of the greatest concern. Leakage of septic tanks, construction of piers, and other disturbances could adversely affect water quality and consequently, the endangered plant and animal populations. Clearing of vast acreages of land around the lake for agriculture has greatly increased the amount of wind-borne sediment deposited in the lake. This has resulted in in- creased rate of siltation, particularly in the eastern and northeastern sections. A detailed water management plan is needed to maintain water levels to sustain healthy fish populations and prevent damage to the freshwater marsh community. A management plan for the lake and the adjoining shoreline park property has been developed by the Master Planning Unit of the Division of Parks and Recreation (Department of Natural Resources and Community Development, 1977). 19, Uses of surrounding land: a.

Regulatory protections in force: The North shore natural area is protected as an official natural area by the Division of State Parks. No construction activities or other disturbances to the vegetation are allowed. The South shore natural area is not officially designated as a natural area; regulatory protection of this area is unclear. 76 22. Threats: The entire north shore bald cypress stand is protected as a state park natural area. There are no known threats to its natural integrity. The south shore marshes are protected as part of the state park but are not recognized as an outstanding natural area at the present time. Increasing development of the south shore for second -home development could adversely affect the marshes by increasing human activity in the area; i.e., swimming and wading uses and possible trampling of the vegetation. 23. Management and Preservation Recommendation: Current recognition of the north shore cypress stand as a state natural area subject to state park regulations seems suf- ficient to protect the natural integrity of the site. The south shore marshes need to be recognized as a unique natural area and periodically patrolled by park personnel to insure that human ` activities are kept at a minimum. Designation of this area as a state registered natural area would focus additional attention on the site and help insure its prdtection. The area should also be included in the N.C. Natural Heritage Program's Registry of Natural Heritage Areas. 77 Natural Characteristics Summar 24a.

Prose Description of Site: The Conaby Creek -Roanoke River Natural Area is located in the northwestern corner of the county. The 3240-acre tract lies at the mouth of the Roanoke River at Albemarle Sound and includes a portion of Conaby Creek, a tributary of the Roanoke which enters the river at a point about one mile from its mouth. The natural area is situated entirely within the Roanoke River floodplain at an elevation between sea level and four feet. The entire tract is underlain by shallow to deep deposits of organic muck which are interbedded with layers of inorganic silts, sands, and clays deposited at various times by river flood- waters. The organic muck soils and permanent high water table are the primary factors which control the vegetation; a structur- ally diverse but ecologically rather depauperate assemblage of swamp forest and pocosin elements. The geological history of the area has recently been studied by Erlich (1980). A brief summary of the interesting geological development of the area follows. The lower Roanoke River basin is an example of a drowned river valley caused by flooding associated with rising sea level. During the Early Holocene Period (7000 years before present), the Roanoke River in the natural area was characterized by typical meandering stream depositional processes. At this time sea level was approximately 46 feet lower than present day levels; there- fore much of what is today covered by Albemarle Sound was at that time an exposed broad, flat plain containing the meandering channel of the Roanoke River. From 7000 years ago to the present the sea level has been gradually rising. Albemarle Sound has been gradually expanding, filling in the former river floodplain. As a consequence of the rising sea level, organic deposits began accumulating in the natural area, covering the inorganic muds and silts deposited during earlier times. Today a vast body of peat -dominated swamp forest wetlands have developed in the lower Roanoke River basin, including the entire natural area section. The vegetation of the natural area is a complex mosaic of various community types, of which all except one are tree -domi- nated swamp forest wetland types. The palustrine/riverine wet- lands have been influenced in the past by natural and man -induced events. The influence of Roanoke River floodwaters carrying sus- pended sediments such as silt and mud, storm and wind tides from adjacent Albemarle Sound, and past logging operations are some 97 of the factors which have combined to mold the vegetation makeup of the natural area. A description of the major community types and several of the minor ones follows in the following paragraphs. Note that only two communities have been given community type designations. The most widespread plant community is Pinus taeda/ Acer rubrum-Chamaecyparis thyoides/mixed wetland shrubs// Smilax laurifolia (loblolly pine/red maple -Atlantic white cedar/mixed wetland shrubs//laurel-leaved greenbriar; CT 1). This community occurs throughout much of the interior of the natural area away from the Conaby Creek -Roanoke River channels and Albemarle Sound. Though dominated by loblolly pine, the canopy contains scattered individuals of baldcypress (Taxodium distichum), pond pine (Pinus serotina), red maple, and locally dense patches of swamp blackgum (Nyssa sylvatica var. biflora). The loblolly pine canopy is typically open and varies from 60-80 feet in height with average dbh values of 10-15 inches. Scat- tered much larger pines are present throughout. The sub - canopy is usually closed and is dominated by varying pro- portions of red maple and Atlantic white cedar. Below the subcanopy is a very dense medium -tall shrub zone containing a mixture of species including sweetbay (Magnolia virginiana), redbay (Persea borbonia), sweet gallberry (Ilex coriacea), and fetterbush (Lyonia lucida). There is no distinct ground cover although chain ferns (Woodwardia virginica and W. areolata) are common along with various sedges (Carex spp.). The lower layers are intertwined by an almost impenetrable tangle of the vine laurel -leaved greenbriar (Smilax laurifolia). Other vines present include poison ivy (Rhus radicans) and climbing hydrangea (Decumaria barbara). Dense sphagnum mats are almost universally present. Along portions of Conaby Creek and the Roanoke River, swamp blackgum-dominated stands are common. This community is identified as Nyssa sylvatica var. biflora/Persea borbonia- Fraxinus caroliniana (swamp blackgum/redbay-Carolina water ash; CT 2). The canopy is usually closed and averages about 50-60 feet in height with an average dbh of 8-12 inches. The shrub layer is composed of redbay and Carolina water ash, two species which are not often found as associates in a swamp forest wet- land. The presence of the ash, a species typical of brownwater river swamps dominated by mineral sediments, is probably due to the silting influence of the channels, discussed in more detail below. The shrub layer is typically not as dense as in the loblolly pine dominated community (CT 1). The characteristic vine of that latter community, laurel -leaved greenbriar, is generally uncommon in the swamp blackgum stands. In some areas beds of lizard's tail (Saururus cernuus) form a distinct ground 98 cover. Other common ground cover species include various sedges (Carex spp.) and netted chain fern. The gum stands are also apparently influenced to some degree by minor and infrequent depositions of suspended silt, deposited during periods of overbank flooding along the channels. Occasional water tupelo (Nyssa aquatica) trees occur along the silty banks of the channels but these are not extensive enough to warrant community type designation. Along the Albemarle Sound shoreline a distinctive band of small to medium sized baldcypress, 30-50 feet high and with dbh's of less than 14 inches is present. This bald cypress fringe extends out into the shallow waters of the sound and are a graphic indication of the rising sea level. This is a minor community within the natural area and is not included in the biotic summary. Another minor community which deserves mention is the Atlantic white cedar -dominated stands which occur primarily along the margin of the valley wall or floodplain escarpment (southeastern edge of the natural area). These monospecific stands are composed of dense, closed stands of cedar 20-50 feet tall which are usually even -aged. A mixture of shrubs such as fetterbush and redbay is present underneath. These cedar stands occur over peat containing a mixture of sandy mineral soil washed in from the adjacent uplands. The communities described up to now represent forested palustrine or riverine wetland systems associated with deep peat or interbedded inorganic muds and peat. Another plant community, dissimilar from the others occurs along the margins of Conaby Creek and the Roanoke River. A submerged, aquatic community dominated by aquatic plants is present. Floating mats of cow -lily (Nuphar luteum var. luteum) and fragrant water -lily (Nymphaea odorata) are associated with other aquatic species such as bladderwarts (Utricularia spp.) and water-milfoils (Myriophyllum spp.). This community is in shallow, sheltered coves and backwaters along the channel margins. The entire natural area is essentially flat. Elevation ranges from sea level along the waterways to 5 feet along the floodplain margin. There are no subaerial topographic land - forms such as sand ridges present in the natural area. A mantle of organic sediments essentially covers the natural area from the channel margins inward to the valley wall. These organic soils are mapped as the Dorovan series: dysic, thermic Typic Medisaprists (SCS, 1981). These soils are characterized by an organic surface layer 51 to greater than 91 inches thick over unconsolidated fluvial inorganic sedi- ments. The peat has a mineral content of 5 to 20%. 99 The water table is at or very close to the surface year- round. The position of the natural area within a floodplain at or slightly above sea level is the primary reason for the high water table. The natural area is the only one of six natural areas in Washington County which is completely roadless. Several minor ditches have been constructed into the margins of the swamp but these have had little, if any, effect on the hydrology. Apparently, all logging operations up to the present have removed timber either by barge or by temporary skid -roads. Because of the inaccessibility of the swamp forest, little is known concerning the wildlife values of the natural area. White-tailed deer, river otter, and black bear are known to occur; the latter species probably only as an occasional visitor. The large size of the tract, combined with continuous riverbottom wetlands further upstream, comprises an extensive woodland corridor which undoubtedly serves as important habitat and refuge for many game and non -game mammals and birds. The lack of roads and the dense vegetation render the tract virtually inaccessible to man. This factor is significant because it pro- vides many species, particularly large wide -roaming mammals such as black bear, a safe refuge from hunting pressures. 100 llb. Prose Description of Site Significance: The Conaby Creek -Roanoke River natural area is the largest tract of roadless wilderness existing in Washing- ton County. Both black bear and river otter, considered rare throughout the coastal plain, occur respectively, within the extensive swamp forest and along the water- ways. The swamp forest contains extensive stands of second - growth loblolly pine, Atlantic white cedar, baldcypress, and swamp blackgum. Although not pristine, these forest stands are significant in their acreage and their inacces- sibility. The swamp forest serves as an important wildlife refugium. When combined with adjacent riverbottom wetlands of Bertie County upstream, the natural area encompasses the largest continuous, relatively undisturbed alluvial wetland ecosystem in northeastern North Carolina. 101 0 N 12.

Uses of natural area: The portion of the natural area owned by Georgia-Pacific Corporation is open to public hunting under the N. C. Wildlife Resources Commission Gamelands program. Because of the lack of roads, dense vegetation, and general inaccessibility it is un- likely that any section of the natural area receives much hunting pressure. The entire area has been timbered, primarily by tram and scid roads during the early 1900's. There is some evidence of fire in the 1930's (Pat White, pers. comm., 1982). There has apparently been no large scale logging operations within the past 70-80 years. This is the only truly roadless area remaining in Washington County. 19, Uses of surrounding land: a.

Regulatory protections in force: Dredge and fill permits under Section 404 of the Clean Water Act apply to the natural area and are regulated by the Army Corps of Engineers. 106 22. Threats: One landowner has recently asked for a federal dredge and fill permit to mine sand and gravel near the western margin of the natural area. This landowner also has property contained within the natural area. It is conceivable that future mining in the area is a possibility. Timber operations also pose a potential threat. Much merchantible timber remains in the area although access roads and ditches will need to be built in order to log the area using modern methods. Because of the high ash content of the peat deposits and their location within the floodplain, the possibility of future peat mining is considered to be very low (Lee Otte, pers. comm. 1982). 23. Management and Preservation Recommendation: The natural area should be preserved in its present roadless condition. Construction of access roads or drainage ditches should not be allowed so that the natural hydrological systems can remain intact. Some selective timbering by barge could be allowed without damage to the natural integrity of the site. The area should be considered an important wetlands resource and protected for its scenic, wildlife, and fisheries values. Any dredge and fill per- mit applications should be reviewed carefully. 107 Natural Characteristics Summar 24a.

Prose Description of Site: INTRODUCTION The Bull's Neck Swamp Natural Area occupies a large peninsula along the southern margin of Albemarle Sound in northeastern Washington County. The natural area encom- passes about 6450 acres containing a mosaic of wetland habitats over both organic and mineral soils. It is by far the largest significant natural area remaining in the county. Before describing the habitat diversity of the site, an introduction to the area's geology and developmental history will be outlined. According to Erlich (1980) Albemarle Sound is an example of a drowned river valley. About 8,000 to 10,000 years ago sea level was at least 46 feet lower than the present-day level. At this time the Albemarle Sound basin was a vast alluvial floodplain containing a meandering river channel and extensive swamp forests. Since that time rising sea levels have caused large scale flooding and enlargement of the Albe- marle Sound to its present dimensions. Parts of the original river floodplain have filled in with organic deposits caused by an accumulation of decomposing swamp forest and marsh vegetation. The present day lower portions of the Roanoke River basin (see Conaby Creek Natural Area site report, pp. ) and the Bull's Neck peninsula are examples of this organic sedimentation. Close examination of aerial photographs of Bull's Neck reveals a series of long, arcuate sand ridges representing a relic fluvial ridge and swale system which was probably formed during a low sea level stand. Some of these ridges rise 5-8 feet above modern sea level and have been cleared for cul- tivation. Other ridges (within the natural area boundary) are much lower, 1-4 feet msl; and are periodically flooded by storm tides. The mantle of organic deposits has apparently covered all but the highest portions of these low -elevation ridges. This topographic diversity has created areas of very deep peat (former sloughs between the ridges), areas of very shallow peat (overlying low, now -buried portions of the sand ridges), and areas of higher ridges domi- nated by loamy sands (not yet covered by the slowly advancing peat mantle). 119 This diverse geomorphology accounts partly for the habitat diversity of Bull's Neck. A complex history of past logging disturbances and wildfires combine to create a mosaic of vegetation types, all of which reflect patterns relating to soils, topography, degree of flooding, and human disturbance. VRGRTATTON The largest acreage, high -quality plant communities at Bull's Neck are the Nyssa sylvatica var. biflora/mixed wetland shrubs or Nyssa sylvatica var. biflora/Acer rubrum- Persea borbonia/mixed wetland shrubs (swamp blackgum/mixed wetland shrubs or swamp blackgum/red maple -red bay/mixed wetland shrubs; CT 1). These very similar stands are dominated by swamp blackgum in the canopy (maximum height 70 feet) with some denser, closed stands lacking a well- defined subcanopy and other more open ones containing a layer of red maple and redbay. Both have low shrub layers containing various proportions of species such as swamp azalea (Rhododendron viscosum), sweet gallberry (Ilex coriacea), fetterbush (Lyonia lucida), sweet pepperbush (Clethra alnifolia, and blueberry (Vaccinium sp.). There is essentially no herb layer although dense mats of - sphagnum moss are common and widespread. The gum - dominated stands also contain a good proportion of Atlantic white cedar (Chamaecyparis thyoides) in both the canopy and subcanopy layers. Also scattered in the canopy are baldcypress (Taxodium distichum) and loblolly pine (Pinus taeda). The average diameter of the gum canopy trees ranges from 12 to 18 inches, de- pending on cutting history. Scattered large trees up to 28" dbh are present. Charred stumps occur in scattered places in the gum stands indicating that fire has played some role in the ecology of the area. However, there is no evidence of fire in recent times; i.e. within the past fifty years. In areas where more intensive cutting has taken place, such as in portions of the southern and western margins of the natural area, loblolly pine and red maple are much more predominant in the canopy. Some areas which were intensively logged are dominated by these two early successional species. The gum stands occur in areas which are mapped as the Dorovan muck soil series. These organic soils average from 51 to greater than 99 inches in the depth of their muck surface horizons. They are very poorly drained and 120 are saturated for most of the year due to a high water table (SCS 1981). The gum stands are most extensive in the central portion of the site (see map) where organic soils of moderate depths are prevalent. Scattered throughout much of the natural area are dense stands of even -aged Atlantic white cedar (CT 2). These stands vary in height and average dbh depending on their age and cutting history. Stands sampled during this survey ranged from 20-30 feet in height and 3 inches average dbh up to 40-50 feet tall and 10 inches dbh. The white cedar stands are characterized by a very high stem density, exclusion of most other swamp forest trees and shrubs, and a uniform height and size. Fire, or more likely, previous clearcutting account for the even -aged and dense character of these stands. Other species present in the white cedar stands but usually of scattered occurrence include red maple and redbay. Mats of sphagnum moss are often common ground cover. The physiognomy of Atlantic white cedar is highly variable in the natural area. The species occurs as scattered individuals in the previously described gum- ' dominated -communities (CT 1) and also in the pond pine stands (CT 3) . The dense stands of Atlantic white cedar (CT 2) vary from less than one acre to about 220 acres in size. The dense stands (CT 2) occupy about 350 total acres, or about 5.4% of the natural area. The 220-acre stand is significant enough to describe in more detail. This stand is located near the northern point of the peninsula (Laurel Point) and has a distinctive linear, east -west alignment, about 1.5 miles long by 0.25 mile wide. Site surveys and inspection of aerial photo- graphs suggest that this stand occurs on shallow peat overlying a partially buried sand ridge. Its alignment is similar to exposed sand ridges to the south. Buell and Cain (1943) describe the general habitat of this species as "peat bog underlain by sand." They mention that hardwood or cypress swamps are more likely to de- velop where the underlying mineral layers are composed mainly of silts and clays. White cedar is also known to require open, sunny conditions for germination (op. cit.). The clearing agent was originally fire, although present timber clear cutting practices often create ideal conditions for the germination and establishment of cedar stands. As mentioned earlier in this discussion, logging activities have been prevalent in Bull's Neck at intervals 121 since the late 19th century. Tram roads were used to haul timber out during the early 1900's before the ad- vent of modern road and canal construction. It is likely that most if not all of the dense white cedar stands in Bull's Neck Swamp are the result of past timber_ cutting. The third high -quality community type located in Bull's Neck is Pinus serotina/Chamaecyparis thyoides- Acer rubrum/Myrica heterophylla-Baccharis halimifolia/ mixed marsh herbs (pond pine/Atlantic white cedar -red maple/bayberry-groundsel tree/mixed marsh herbs; CT 3). This community is dominated by an open stand of pond pine over an open subcanopy of Atlantic white cedar and red maple. A low shrub layer of bayberry and groundsel tree occurs throughout much of the com- munity over a mixture of marsh herbs. Common herbs include pickerelweed (Pontederia cordata), sedges (Carex spp.), tear -thumb (Polygonum sagittatum), and marsh pennywort (Hydrocotyle sp.). Canopy height ranges from 40-50 feet with trunk diameters of 8-12 inches. This community is restricted to the northernmost point of Bull's Neck in an area just north of the large white cedar stand previously described. It occupies an area of about 664 acres, or about 10% of the natural area. The area is underlain by Dorovan muck, already described. The community is an unusual one, containing an assemblage of species not typically found growing together. It appears to be in a state of transition from pond pine -white cedar forest to a shrub -marsh system. Almost all of the white cedars in the com- munity appear to be under stress and many have recently died. Dead cedar trunks are scattered throughout. Reasons for this are unclear. The pond pines appear to be healthy, although somewhat stunted and the red maples also seem to be relatively healthy. Could rising sea level coupled with increasing salinity be the reason for the cedar's demise? This seems to be a good possibility since other possible factors such as disease or insect predation should affect trees throughout the natural area. White cedar stands in other, more inland portions of the natural area seem to be thriving and healthy. 122 The three previous communities are all swamp forest systems over shallow to deep organic deposits. The fourth community type differs in having a mineral soil type and somewhat better drainage. This type, Pinus taeda/Acer rubrum (loblolly pine/red maple); CT 41 is located on loamy sand ridges scattered within the natural area and lying 2-4 feet in elevation above the surrounding peat - dominated wetlands. These ridges, the remnants of the ridge-and-swale system noted above, exist as isolated, elongated islands oriented generally in a east -west direction, and ranging from several acres to about 185 acres in extent. Most have been timbered extensively and are presently vegetated with young -growth stands of loblolly pine, red maple, and sweetgum. A few of the more remote islands, located in the southern portion of the natural area contain stands of pine 70-80 feet high. A diversity of shrubs and herbs occur including flowering dogwood (Cornus florida), bayberry, American holly, sourwood (Oxydendrum arboreum), American beech (Fagus grandifolia), various oak species (uercus spp.), tulip -poplar (Liriodendron tulipifera), Japanese honey- suckle (Lonicera japonica), partridgeberry (Mitchella repens), and poison ivy (Rhus radicans). Early tramroads apparently followed these islands, using them as convenient bridges to reach the less ac- cessible swamp forests. Later, road systems and canals were constructed across the larger ridges. Consequently, little timber remains today and the ecological signifi- cance of the pine ridges has been substantially reduced. The soils of the ridges are mapped as the Dragston loamy fine sand series, a somewhat poorly drained wet soil that is flooded occasionally. WILDLIFE AND AVIAN DIVERSITY Because of its large size, habitat diversity of pine ridges, cedar stands and hardwood swamps, Bull's Neck would be expected to represent highly significant wild- life habitat. In some respects the area does seem to have high wildlife values, in others it appears to be rather depauperate. Four days of field work in the area failed to reveal the presence of any white-tailed deer, a very unusual situation considering the habitat, and the fact that Washington County has one of the largest deer herds in the North Carolina coastal plain (Rod McClanahan, WRC Biologist, pers. comm. 1982). The apparent absence of deer in the area begs explanation. 123 However, black bear are known to occur (R. McClanahan, pers. comm., 1982) and a set of tracks and scat were ob- served. The size of this population is unknown. Inform- ation on the presence of other furbearers is not available. Breeding bird diversity is high, with at least 47 species known or suspected of nesting in the area. In this regard, Bull's Neck compares favorably with the Van Swamp natural area (See pp. ). Breeding birds include ten species of wood warblers and 5 species of woodpeckers, both considered excellent totals for the coastal plain. 124 llb. Prose Descriptiou of Site Significance Bull's Neck Swamp does not contain any highly significant or unique old -growth timber stands nor does it contain any out- standing wildlife populations or endangered species. Its chief value is the areal extent of the wetland forests; the largest continuous tract of swamp forest vegetation in a relatively natural state in the county. Only two major canal/roads tra- verse the peninsula and much of the swamp forests are virtually inaccessible. The area functions as a wildlife refugium, and its importance in this regard will surely increase as areas to the south continue to be drained and cleared for agriculture and silviculture. The swamp also has the largest acreage of pure Atlantic white cedar stands in the county (about 350 acres). It contains habitat supporting populations of at least two species considered rare or threatened in North Carolina, black bear and red -shouldered hawk, respectively. 125 12.

Uses of natural area: The Bull's Neck Swamp Natural Area has been registered in the past as a state gamelands (1980-81) although with a recent change in ownership the present gamelands status is uncertain. Because of the scarcity of white-tailed deer, the swamp is presently under very little hunting pressure. Locked gates or ditches prevent vehicular access by any land route. Since the area is bounded on three sides by. Albemarle Sound and Bull's Bay, the swamp shoreline is accessible by boat. Because of the swamp's dense forbidding vegetation there is little likelihood that anyone attempts to enter the swamp interior by this method. In the past the entire swamp has been logged, most recently in the 1950's and 1960's. 19, Uses of surrounding land: a. Wildland 80 % b. Agricultural land 20 % 20. Preservation Status: c. high -intensity forestry % d. developed % Cat * % *Description of preservation status 6 100 not protected by owner 21. Regulatory protections in force: The Army Corps of Engineers has jurisdiction over the area concerning Section 404 permit applications for dredging and filling operations. 131 22. Threats: The natural area is probably protected from most high - intensive operations because it is 1) very low in elevation (0-4 feet msl), 2) adjacent to navigable waterways and sub- ject to federal permit regulations, 3) subject to storm -tide flooding, and'4) it contains low -value peat reserves (high ash content). However, intensive timber operations could significantly decrease the swamp's natural significance. Large-scale ditching could lower the water table and com- bined with heavy cutting of the swamp gum, baldcypress, and white cedar, could result in the establishment of a swamp hardwoods community dominated by "weedy" species such as sweetgum and red maple. 23. Management and Preservation Recommendation: The area should be preserved in its natural state with no further road or canal construction. Timber operations should be limited to small (less than 50 acres) clearcuts or light selective cutting to maintain dominance by swamp blackgum and other dominant swamp trees and prevent invasion of early suc- cessional "weedy" species such as sweetgum and red maple. Its importance as a floodplain wetland ecosystem should be recognized by county planners and efforts should be made to preserve its natural integrity. 132 Natural Characteristics Summary 24a.

Prose Description of Site: The Chapel Swamp Natural Area is a 149-acre tract which contains the narrow alluvial floodplain and adjacent upland slopes of a small stream draining the southern margin of Albemarle Sound. The natural area contains the best preserved examples of upland slope and alluvial floodplain communities remaining in Washington County. Chapel Swamp is a small, low -gradient stream which drains a portion of the upland mineral soils which occur as a relatively narrow band 2-3 miles wide along the south side of Albemarle Sound. The stream is one of several lo- cated along the northern border of the county between Mackeys and the Tyrrell County line. The narrow alluvial floodplain along the meandering channel is dominated by swamp forest typical of alluvial brownwater rivers and streams of the coastal plain. The plant community of the floodplain is Nyssa aquatica/Saururus cernuus (water tupelo/lizard's tail; CT 1). It is dominated by water tupelo (Nyssa aquatica) in the canopy over a sparse, poorly -developed shrub layer of carolina water ash (Fraxinus caroliniana) and virginia willow (Itea virginica) over a ground layer locally domi- nated by dense patches of lizard's tail (Saururus cernuus). The water tupelo average about 60-70 feet in height and have an average diameter at breast height (dbh) of about 28 inches. Scattered very large, old -growth trees up to 45 inches dbh are present. Mixed with the gum are scattered baldcypress (Taxodium distichum) up to 90 feet tall and 43 inches dbh, cull trees which were not harvested during earlier periods of timber removal. Scattered very large cypress stumps indicate that the swamp forest community was probably dominated by cypress prior to logging activities. The water tupelo swamp forest stand is characterized by the distinct, swollen bases of the trees, an indication that deep flooding of the swamp is a periodic occurrence. Water lines on the trees indicate flooding depths of up to two feet. The swamp soils are mapped as Dorovan mucky silt loam overwash, an organic soil that has developed a shallow mineral surface horizon (SCS 1981). These silty loam soils apparently account for the presence of water tupelo, a species more com- monly associated with silty and clayey swamps of larger brown - water river bottoms. The water tupelo swamp is the only well - developed, mature stand known in Washington County. This species is at or very near the eastern margin of its range in the Pamli 149 marle Peninsula at this site. Adjacent to the swamp are a series of slopes which rise 5-6 feet above the floodplain. Along the gentle (2-60) slopes and the relatively flat ridgecrests the plant community (CT 2) occurs: Mixed upland hardwoods/Fagus grandifolia transgressives or Ostrya virginiana (Mixed hardwoods/American beech trans- gressives or hop hornbeam). This upland, terrestrial community contains several species of hardwoods, the two most common being white oak ( uercus alba) and American beech. Species also pre- sent in the canopy in smaller proportions include southern red oak (Quercus falcata var. falcata), tulip poplar (Liriodendron tulipifera), loblolly pine (Pinus taeda), black gum (Nyssa sylvatica var. sylvatica), and pignut hickory (Carya glabra). These upland hardwood stands average 60-70 feet in height and 20-22 inches dbh. A fairly well -developed subcanopy layer dominated by younger American beech and, locally, by hophorn- beam is present. Also present in the shrub layer are scattered clumps of silky camellia (Stewartia malacodendron), a tall shrub which is uncommon and local throughout most of the coastal plain. The natural area is the only known location for the species on the Pamlimarle Peninsula, excluding Beaufort County. The ground layer is typically sparse but contains small patches of lady fern (Athyrium asplenioides), New York fern (Thelypteris noveboracensis), mayapple (Podophyllum peltatu m), and other herbaceous species. - The upland hardwood stands represent a plant community which is of very limited extent in the county and which is - at the eastern limit of its range in the Pamlimarie Peninsula. Although topographically the region is no higher than the extensive wetlands of the East Dismal Swamp to the south, these slopes and low ridges are much better drained. The better drainage is the result of the series of dendritic stream basins, such as Chapel Swamp, which drain into ad- jacent Albemarle Sound, located about � to � mile away from the natural area. The soils of the uplands are mapped as the Altavista, Dogue, and Wahee series, all of which are fine sandy loams and differ only in minor degrees of drainage and mineral particle size content. Because of their better drainage, most of these soils have been cleared for agriculture for some time. Most of the earlier farming settlements of Washington County were in this zone of mineral soils along the south edge of Albemarle Sound. Geologically, the natural area lies on the Pamlico Terrace, a flat surface comprised of marine sediments de- posited some 100,000 years ago when sea level was much higher and the shoreline was along the Suffolk Scarp, at 150 about the present-day 25-foot contour level (Ingram and Otte, 1982). At about 18,000 years ago the sea had re- ceded to about 400 feet below the present level. At this time, downcutting by streams produced the series of slopes and dendritic drainages such as Chapel Swamp (op. cit.,1982). From 18,000 years BP to the present day sea level has been gradually rising and downcutting by the streams has essentially stopped. The upland hardwood stands which were probably much more extensive in the region during the low sea level period have been steadily encroached upon by rising waters of the sound and peat - dominated wetlands to the south. They can be considered a relict community which has persisted to the present day within the natural area because of adequate drainage as- sociated with the more dynamic topography. In terms of average size of trees, minimal degree of past timbering disturbances, and lack of non-native species invasion, the upland hardwood stands of the natural area are the best examples of this community type known in the Pamlimarle Peninsula. The water tupelo swamp forest is the best example of an old -growth, relatively undis- turbed alluvial floodplain stand in the Pamlimarle Penin- sula. Together these two forest types comprise a near - pristine example of an ecosystem which has almost com- pletely disappeared from the Washington County landscape. Because of the small size of the tract, the natural area is not believed to be of great significance as wild- life habitat, particularly for wide-ranging mammals. Despite its small size, the tract contains at least 30 species of breeding birds, including one species that deserves special mention because of its rarity in the Pamlimarle Peninsula. Several pairs of white -breasted nuthatches nest in the swamp and upland forests along Chapel Swamp. This species is known elsewhere in the county only from Van Swamp and Lake Phelps; populations are very local and scattered in adjacent Tyrrell, Beaufort, and Hyde Counties. In the Coastal Plain it usually occurs in brownwater river swamps and extensive mesic hardwood flats, primarily in areas with old -growth or mature, second -growth timber. 151 llb. Prose Description of Site Significance: The Chapel Swamp Natural Area contains the best examples of alluvial floodplain swamp forest and upland hardwood com- munities known in the county. The swamp forest dominated by water tupelo is the only example of that community type known in the county and is also significant because of the old -growth age of the stand and the relative lack of dis- turbance. The upland hardwoods community is equally sig- nificant in that it represents an old -growth, relatively undisturbed example of a climax forest type which is very limited in the outer coastal plain and which has in most regions been almost completely cleared for agriculture. Although the site contains no plant or animal species listed as endangered in the state, it does contain a significant population of silky camellia (Stewartia malacodendron) a tall shrub which is uncommon and local in the North Carolina coastal plain, and a breeding population of red - shouldered hawks, a species considered to be threatened throughout the state (Cooper, et al, 1977). The locally rare white -breasted nuthatch, a species of small bird, also occurs on the tract and is one of only three breeding populations known in the county. 152 H u, w 12.

Uses of natural area: Chapel Swamp is apparently used sparingly by squirrel and deer hunters in season. The highest -quality portion (see map) of the natural area has not been timbered within the past 50 years. Old stumps indicate that some selective cutting occurred sometime ago. The natural area is an essentially undisturbed but unfortunately small remnant of the upland hardwood and alluvial swamp forest communities which formerly occurred on the better drained soils along the south margin of Albemarle Sound. 19, Uses of surrounding land: a.

Regulatory protections in force: None known. 157 22. Threats: The threat of logging is always present as it is with most natural areas. Possible widening to four -lanes of the US 64 highway would remove a significant portion of the high - quality natural area. Additional clearing for agriculture is possible on the upland portions of the tract. 23. Management and Preservation Recommendation: The area could be protected if included in the North Carolina Natural Heritage Program's Registry of Natural Heritage Areas. The primary landowners should be contacted about a possible registry agreement. It is recommended that the tract be set aside in its present undisturbed condition and managed as a state or county natural area. The site would make an ideal location for a county or regional park as long as construction of parking lots and other facilities was limited to already cleared upland areas adjacent to the natural area. A series of interpretive trails could be built which il- lustrate the natural history of the area. 158 d 'Natural Characteristics Summary 24a.

Older cypress fringe has its trees standing in water while young cypress fringe occupies sandy beaches in front of eroding sand or clay banks. dbh - Diameter at breast height (diameter of tree in inches measured at a point 4.5 feet above the ground). ecological succession - Process by which one community of living organisms is gradually replaced by another. Usually each succes- sive community is more stable than the last, thus leading toward a final community especially well suited to the particular environ- mental conditions existing at that location. flood plain - Lowlands adjacent to a river or stream which become inundated during periods of high flow. Flood plains are a natural component of the river system and function as overflow storage areas. msl - Mean sea level. Pamlico Terrace - A low, flat, featureless, topographic surface extending over the Coastal Plain of the Southeastern U.S. at elevations less than 20 feet above sea level. It is considered the relict sea floor of the Sangamon Interglacial. Pamlimarle Peninsula - The peninsula bounded on the north by Albe- marle Sound and on the south by the Pamlico River. Includes all of Washington, Beaufort, and mainland portions of Dare and Hyde Counties. a s 172 peat - Accumulations of slowly decomposing plant remains. Peat is formed in swamps and marshes. Erosion of peat soils releases suspended organic matter into coastal waters as well as certain 'humic acids' which give water a tea colored stain. Pleistocene Epoch - That period of earth history which saw the advance and retreat of the four great Ice Ages. It is generally considered to have begun between 1 and 2 million years ago and to have continued up until about 18,000 years ago. relict beach ridge - Throughout the Southeastern U.S. ancient shorelines are detected at various elevations inland from the coast. These shorelines are often manifested as continuous ridges and are considered a product of higher stands of the sea during the Pleistocene Ice Ages. Sangamon Interglacial - A period of deglaciation (no continental ice sheets) during the Pleistocene Epoch between the Illinoian and Wisconsin Ice Ages. This period is generally considered to have taken place about 80-100,000 years ago. sp and spp - Species (singular and plural). Suffolk Scarp - A topographic ridge rising from 20 to 40 feet above sea level which runs parallel to the coast throughout North Carolina. It is considered an ancient shoreline formed during the Pleistocene Epoch. swamp forest - Type of forest characterized by seasonal flooding a and water saturated organic soils. Water tupelo, swamp black gum and bald cypress are dominant tree species. Talbot (Chowan) Terrace - A rather flat but stream -dissected sur- face lying at an average elevation of 40-45 feet throughout South- eastern United States. It is considered to have been a sea floor during the Pleistocene Epoch. In North Carolina it lies west of the topographic ridge known as the Suffolk Scarp. Yorktown Formation - An ancient deposit of clay and clayey sand which typically contains abundant marine fossils including clams, snails, whale vertebrae, and shark teeth. It occurs extensively over eastern North Carolina and is generally considered a deposi- tional product of the Miocene Epoch which took place 15-20 million years ago. 173 r CRESWELL, N.C.

This classificaton process will serve as a guide for future growth in the county and may be used with land use controls such as zoning, subdivision regulations, building codes, floodplain restrictions, and dredge and fill permits. This Land Classification System is based upon the county's existing land use pattern, population and economic fore- casts, natural and scenic features identified, soil types, and the local government's ability to finance services to growing areas. The System has five designations of land: Developed, Transi- tion, Community, Rural and Conservation. Here's what each category describes: DEVELOPED LAND CLASSIFICATION. This refers to large towns and cities having complete city services such as water, sewer, police protection, and fire protection. In Washington County, this category describes the Town of Plymouth. TRANSITION LAND CLASSIFICATION. This refers to fringe areas around "Developed" areas which are likely to grow in population to become "Developed" areas in the future. "Transi- tion" areas require the most detailed planning because local government must carefully weigh the cost of extending services against its ability to pay. In Washington County, the only "Transition" areas identified are near the Town of Plymouth and in parts of Roper. COMMUNITY LAND CLASSIFICATION. This refers to small towns and other areas where population growth is occurring, but not as fast as in the "Developed" and "Transition" areas. Consequently, the services planned are on a smaller scale. For example, a "Community" area's population may be large e- nough to support a public water system but not a public sewer system. In Washington County, "Community" areas describe Creswell and parts of Roper, the Macedonia area, the water- front communities along all of Albemarle Sound and the Lake- shore surrounding Lake Phelps. RURAL' LAND CLASSIFICATION. This refers to the prime areas for row crops and commercial forests which need to be reserved for that activity. These areas have few services planned in order to discourage manufacturing and other urban land uses. Instead these uses should be located nearer the towns where tax -supported services can be provided most efficiently. Most of the land in Washington County fits the "rural" description, except for the towns, the state park, the wildlife refuge, and the small beach communities. CONSERVATION LAND CLASSIFICATION. This refers to lands which need to be kept in their natural state in order to preserve some cultural or environmentally sensitive area for the public good. Such areas include historic sites like Somerset Place and the public trust waters of Albemarle Sound. IMPLEMENTATION After an extensive public participation program and the required public hearings, the Town's Land Use Plan was sub- mitted to the Coastal Resources Commission for approval. The boundaries of the Areas of Environmental Concern will be adopted by the Coastal Resources Commission near the end of 1977. These areas may include marshlands, beaches, sand dunes, navigable waters, national and state parks and areas of historial importance. Designation of an area as one of environ- mental concern does not prohibit use of that area. It is only a warning sign to be careful. Any development within an Area of Environmental Concern must have a permit. The Act does not require a permit for development outside Areas of Environmental Concern. The Act requires the following projects in Areas of Environmental Con- cern to obtain a permit from the Coastal Resources Commission: those projects currently needing state permits, those of greater than 20 acres in size, those that involve drilling or excavating natural resources on land or underwater, and those which involve construction of one or more structures having an area in excess of 60,000 square feet. Local governments will establish regulations for the types of developments in areas of environ- mental concern which will need permits from them. Local development regulations will be revised to conform to the plan requirements within the Areas of Environmental Concern. The objectives listed in the Plan will be implemented through the capital budgeting program and local development regulations. PERIODIC REVIEW Planning under the Coastal Area Management Act is recog- nized as a continuing process. The planning guidelines require that the Land Use Plan be periodically reviewed and revised in the light of changes in life style, economic pressure, and environmental pressure. The Town of Emerald Isle will review its Plan at a public meeting annually. Town citizens are requested to exercise their civic responsibility by helping the elected government maintain a development course which will not degrade the life -supporting capacities of Emerald Isle. 7 t SCALE: VI0 2AO 3110 4/10 5/10 %z MILE ROP t t SCALE: yo WASHINGTON COUNTY NORTH CAROLINA SCALE 1 0 1 2 3 4 MILES --4 �� � � MILE 0 01� SCALE FOR ENLARGEMENTS - N 1 N V „ O 130 uo , / WASH11�10%,.... ■ /"/ ■P& ■4\/ N� I o 0 1976 This report was financed in part by the National Oceanic and Atmospheric Administration, the Coastal Plains Regional Commission, and the State of North Carolina; and meets the requirements of the North Carolina Coastal Area Management Act of 1974.

Similar improvements were recommended for the Town of Plymouth. Its existing treatment facilities should be upgraded to meet state pollution requirements, as well as new industrial and residential needs in the town's fringe area. At this time, no other sewer service was proposed to other areas of the county. Funds for construction of the proposed water and sewer improvements could be derived from general obligation bonds, from the sale of revenue bonds, state and federal grants, or tap -on fees paid by new customers. Construction costs, paid through general obligation bonds, are repaid by all county taxpayers. Users of the service pay an additional cost to operate the plant and meet interest. Their payments could be derived from tap -on fees and monthly sewer bills. School facilities can be financed through a similar system of state and local bonds, and state and federal grants. Operating expenses and interest could be paid through property assess- ments and supplementary state and federal programs. The justification for "mortgaging the future" to have these facilities involves two considerations. First, most local residents feel that they live in a good county. Helping improve county services keeps it that way. This is based on the certainty which a number of county residents have that paying for better schools, tasteful water, or a fool -proof system for sewage disposal is better than doing without these things. Second, development is certain to occur in this region in the future. To a certain extent, it is dependent upon the availability of services and facilities from local government. If some adjacent county is chosen for new business or industry, then property owners here will not only lose the tax relief they may have had, but could also incur heavier taxes from services new residents need who live here but work elsewhere. Although new industry has not been quick to settle here, a defeatest mentality in itself deters investment and accelerates outmigration of our young people. A change in at- titude is necessary for us to accept our "smallness" as an asset worth retaining. At the same time, we all have a responsibility to remind our elected officials that our county has a particular need to plan and coordinate all its actions. These actions should insure that as our county grows, one set of serious problems will not be replaced by another. Economic Trends Large scale farming and forestry should continue to dominate the county's economic growth. During the early history of the county, Somerset Plantation's 100,000 acre farm could be considered as the forerunner of today's First Colony Farms. After the Civil War, the John L. Roper Lumber Company began acquiring property in eastern North Carolina that by 1910 exceeded 600,000 acres. The Roper Lumber Company encour- aged farmers to settle in the area and grow crops on their cleared tracts, thus accelerating the development of the coun- ty's agriculture. Today the Weyerhauser and Georgia-Pacific mills in Plymouth are the familiar evidence of this major trend's impact. Future major impact upon the local economy focuses on agriculture. In the next ten years, forest in the Newland Road area below Roper is expected to be cleared and brought into agriculture production. This is based upon the county's ac- celerated land clearing activity by corporate "superfarms." With improved management of population, a modern generation of agri-industry can become a new and important part of Washing- ton County's economy. Potential Areas of Environmental Concern One major requirement of the Coastal Area Management Program is to protect certain environmentally sensitive areas which will be known as Areas of Environmental Concern, or AEC's. Final designation of the AEC's will occur after a major However, until new jobs accompany increased farm produc- tion, population growth will be minimal as young and old alike move elsewhere for work. Countering this out -migration is the in -migration of families looking for second homes along our shores. Although this in -migration is continuing, it will be small compared to the growth of the popular resorts in Nags Head, Kill Devil Hills, Kitty Hawk, and elsewhere. Land Use Issues and Problems These major trends create land use issues: (1) How does "superfarming" affect the water used for drinking and recre- ation? (2) Should taxpayers or shoreline property owners pay the costs of bulkheading beach property lost to ,soil erosion? (3) How far out must utilities be extended to serve growing areas before they become economically feasible? Other problems include the need for more business and industry in the area to diversify the tax base; more and better housing; better police protection; dog control; storm drainage; and the need for more GOAL: TO PROVIDE FOR THE ECONOMIC NEEDS OF COUN- TY RESIDENTS BY ATTRACTING NEW BUSINESS AND INDUSTRY TO WASHINGTON COUNTY. (1) Establish an Economic Development Commission to encourage new industry in Washington County. Hire a full-time industrial developer as a staff for the Economic Development Commission (2) Recommend to the State Department of Transporta- tion that U.S. Highway 64 be widened to four lanes across the county. (3) Support the development of a community water system in the county. (4) Propose a Wenona-to-Pea Ridge road to the State Department of Transportation. (5) Work with the surrounding counties to petition the study of an interstate coastal highway. GOAL: TO PROTECT NATURAL AND CULTURAL RESOURCES (1) Improve storm drainage on all creeks in the coun- ty to minimize local flooding.

In the plan, stated goals and objectives deal with these issues and problems. Land Use Goals and Objectives An important part of any plan is setting goals and objectives. Carefully prepared goals and objectives represent local resi- dents' opinions and desires for their county's future growth. They are used in two ways. First, they describe the changes and improvements you told us you wanted, touching such topics as economic growth of the county, protection of natural re- sources, and improvement of local government. Secondly, they establish the framework for future policies, programs and land use regulations that help implement the plan. Through this process land use changes can be guided by your local govern- ment instead of occurring in a haphazard manner. The following list"of community objectives describe short - run priorities —things which could be accomplished in the next two years. GOAL: TO IMPROVE THE LEVEL OF SERVICE OF LOCAL GOVERNMENT (1) Improve county police protection, especially a- gainst breaking and entering. (2) Develop a Zenith emergency phone number system to eliminate long distance calls to Plymouth from Creswell. (3) Establish a dog catcher and kennel for dog control in the county. (4) Recruit adults to expand supervised league sports in . the county. (5) Expand efforts to publicize the Health Department's schedule of services to outlying areas. (6) Adopt a Minimum Housing Code. (7) Expand library services in the Creswell area. DEVELOPMENT OBJECTIVES FOR ROPER (1) Improve storm drainage within the town limits. (2) Study zoning and subdivision controls within the town and one -mile surrounding area. (3) Support plans for a community sewer system and improvements to the existing water system. (4) Support the demolition of unsafe buildings and the expansion of new housing in town. (5) Petition the county for increased police patrol service at night. DEVELOPMENT OBJECTIVES FOR CRESWELL (1) Develop zoning and subdivision controls within the town. (3) Construct additional housing of all types in this area. (4) Expand and publicize library and health care serv- ices in the Creswell area. (5) Petition the county for increased police patrol serv- ice at night. Implementing the Plan Without a scheme to develop the county in an orderly fashion, the very features which make this area attractive may disappear under the kinds of growing pains now experienced along the Outer Banks. Clearly, more jobs, better services, an attractive community in which to live, and the efficient use of taxes —these needs of the people —will demand better planning and management in the future from local government. So this plan is intended to be used in the future by the Board of County Commissioners, members of Town Councils, and others in government, as a guide for making policy and adopting pro- grams. Specific tools for carrying out the land use recommendations in the Plan are zoning, subdivision regulations, building and housing codes, flood plain ordinances, sediment control re- gulations, and dredge and fill permits. Each device performs a limited task, and only offers workable solutions to the county's growth problems when used together with the other tools. State law requires that the exercise of these powers be structured through a responsible body of government. In the case of Washington County, the County Commissioners, the various town council, and local planning boards have this authority. Very simply, local government has a responsibility to plan. Elected officials bear a responsibility to guide growth, just as they have a responsibility to plan and budget the county's resources for health services, drainage, and police and fire protection. All of these are a part of Washington County's public interest, and we expect our elected officials to define that interest and protect it. Growth is occurring; as citizens, we can let it continue on an unguided path, or we can try to steer it in a way that creates civic pride and requires less tax money to service. The choice and responsibility for good growth manage- ment is ours. It takes work —and revisions —but is almost always a good investment in time and money. Attend and participate in the meetings of your local planning board. We hope you will help when you can —please participate.
