4.0 BIOTIC RESOURCES
4.1 Terrestrial Communities
Three terrestrial communities were identified in the study area: maintained/disturbed,
Mesic Mixed Hardwood Forest (Coastal Plain Subtype), and Coastal Plain Small Stream
Swamp (Blackwater Subtype). Figure 4 shows the location and extent of these terrestrial
2 October 2017
Natural Resources Technical Report Bridge 080178, Bladen County, NC
communities in the study area. A brief description of each community type follows.
Scientific names of all species identified are included in Appendix B.
4.1.1 Maintained/Disturbed
The maintained/disturbed community occurs throughout the study area in places where
the vegetation is periodically mowed or maintained, such as roadside shoulders,
residential lawns, and utility easements. Dominant vegetation in this community is
comprised of low growing grasses, herbs, and woody vines, including evening primrose,
Chinese lespedeza, Japanese knotweed, ragweed, crabgrass, bicolor lespedeza, morning
glory, muscadine grape, wooly mullein, fescue, passion flower, as well as mimosa,
mockernut hickory, and smooth sumac saplings.
4.1.2 Mesic Mixed Hardwood Forest (Coastal Plain Subtype)
The Mesic Mixed Hardwood Forest (Coastal Plain Subtype) is found in mesic upland
areas protected from fires, primarily on north-facing river bluffs and ravine slopes, less
commonly on upland flats or islands surrounded by peatland or swamp communities.
This community exists in a portion of the northeast quadrant, and in the southeast and
southwest quadrants of the study area. Dominant species in this community include
white oak, tulip poplar, pignut hickory, and loblolly pine in the overstory. Ironwood,
horse sugar, sweetgum, beech, American holly, beauty berry, sassafras, and Chinese
privet comprise the midstory, while roundleaf greenbrier, muscadine grape, yellow
jessamine, Japanese honeysuckle, blueberry, and ebony spleenwort dominate the
understory.
4.1.3 Coastal Plain Small Stream Swamp (Blackwater Subtype)
The Coastal Plain Small Stream Swamp (Blackwater Subtype) is found in the floodplains
of small blackwater streams in which separate fluvial features and associated vegetation
are too small or poorly developed to distinguish. This community bisects the project area
into the northern and southern quadrants. Dominant species in this community include
river birch, red maple, swamp chestnut oak, water oak, tulip poplar, and swamp tupelo in
the overstory. Ironwood, titi, red bay, dog hobble, tag alder, buttonbush, and Chinese
privet comprise the midstory, while Japanese stiltgrass, orange jewelweed, wisteria,
netted chain fern, climbing hempvine, giant cane, roundleaf greenbrier, and tearthumb
dominate the understory. Wetland site WA is classified as a North Carolina Wetland
Assessment Method (NCWAM) Riverine Swamp Forest and is located within the Coastal
Plain Small Stream Swamp (Blackwater Subtype) community.
4.1.4 Terrestrial Community Impacts
Terrestrial communities in the study area may be impacted by project construction as a
result of grading and paving of portions of the study area. At this time, decisions
regarding the final location and design of the proposed bridge replacement have not been
made. Therefore, community data are presented in the context of total coverage of each
type within the study area (Table 4). Once a final alignment and preliminary design have
been determined, probable impacts to each community type will be calculated.

4.2 Terrestrial Wildlife
Terrestrial communities in the study area are comprised of both natural and disturbed
habitats that may support a diversity of wildlife species (those species actually observed
are indicated with *). Mammal species that commonly exploit maintained/disturbed
habitats, forested habitats, wetlands, and stream corridors found within the study area
include species such as eastern gray squirrel, gray fox, striped skunk, white-footed
mouse, eastern cottontail, raccoon, Virginia opossum, beaver*, and white-tailed deer.
Birds common to the area include red-shouldered hawk*, white-breasted nuthatch*,
tufted titmouse*, barred owl*, northern cardinal*, fish crow*, American crow*, Carolina
wren*, and summer tanager*. Reptile and amphibian species that may use terrestrial
communities located in the study area include the rough green snake, green frog*,
copperhead snake, rat snake, eastern box turtle, eastern fence lizard, southern toad, green
anole, gray treefrog, and five-lined skink.
4.3 Aquatic Communities
The aquatic community in the study area consists of a large perennial stream. Species
that could be expected in Browns Creek include various shiners, white catfish, Eastern
mudminnow, various sunfish, and various darters.
4.4 Invasive Species
Eight species from the NCDOT Invasive Exotic Plant List for North Carolina were found
to occur in the study area. Mimosa (Moderate threat), Japanese knotweed (Threat),
Chinese lespedeza (Threat), Japanese honeysuckle (Moderate threat), and bicolor
lespedeza (Moderate threat) were observed in the maintained-disturbed community.
Chinese privet (Threat), Japanese stilt grass (Threat), and wisteria (Moderate threat) were
observed in the Mesic Mixed Hardwood Forest (Coastal Plain Subtype) and Coastal Plain
Small Stream Swamp (Blackwater Subtype) communities. NCDOT will manage for
these invasive plant species as appropriate.
5.0 JURISDICTIONAL ISSUES
5.1 Clean Water Act Waters of the U.S.

5.2 Clean Water Act Permits
The proposed project has been designated as a CE for the purposes of National
Environmental Policy Act (NEPA) documentation. As a result, a Nationwide Permit
(NWP) No. 23 will likely be applicable. A NWP No. 33 may also apply for temporary
construction activities such as stream dewatering, work bridges, or temporary
causeways that are often used during bridge construction or rehabilitation. The
USACE holds the final discretion as to what permit will be required to authorize project
construction. If a Section 404 permit is required then a Section 401 Water Quality
Certification (WQC) from the NCDWR will be needed.
5.3 Coastal Area Management Act Areas of Environmental Concern
Bladen County is not a designated coastal county in North Carolina; therefore, Coastal
Area Management Act (CAMA) regulations do not apply.
5.4 Construction Moratoria
As of September 29, 2017, the North Carolina Wildlife Resources Commission
(NCWRC) does not require an in-water construction moratorium for this project.
5 October 2017
Natural Resources Technical Report Bridge 080178, Bladen County, NC
5.5 N.C. River Basin Buffer Rules
There are no buffer rules in effect for the lower Cape Fear River Basin.
5.6 Rivers and Harbors Act Section 10 Navigable Waters
Browns Creek has not been designated by the USACE as a Navigable Water under
Section 10 of the Rivers and Harbors Act.
5.7 Wetland and Stream Mitigation
5.7.1 Avoidance and Minimization of Impacts
The NCDOT will attempt to avoid and minimize impacts to streams and wetlands to the
greatest extent practicable in choosing a preferred alternative and during project design.
At this time, no final decisions have been made with regard to the location or design of
the preferred alternative.
5.7.2 Compensatory Mitigation of Impacts
The NCDOT will investigate potential on-site stream and wetland mitigation
opportunities once a final decision has been rendered on the location of the preferred
alternative. If on-site mitigation is not feasible, mitigation will be provided by North
Carolina Department of Environmental Quality (DEQ) Division of Mitigation Services
(DMS).
5.8 Endangered Species Act Protected Species
As of July 21, 2016 (Bladen County), the United States Fish and Wildlife (USFWS) lists
seven federally protected species for Bladen County (Table 7). A brief description of
each species' habitat requirements follows, along with the Biological Conclusion
rendered based on survey results in the study area. Habitat requirements for each species
are based on the current best available information from referenced literature andlor
USFWS.

American alligator
USFWS Recommended Survey Window: year-round (only warm days in winter)
Habitat Description: In North Carolina, alligators have been recorded in nearly every coastal
county, and many inland counties to the fall line. The alligator is found in rivers,
streams, canals, lakes, swamps, and coastal marshes. Adult animals are highly
tolerant of salt water, but the young are apparently more sensitive, with salinities
greater than 5 parts per thousand considered harmful. The American alligator
remains on the protected species list due to its similarity in appearance to the
Endangered American crocodile.
Biological Conclusion: Not Required
Species listed as threatened due to similarity of appearance do not require Section
7 consultation with the USFWS. However, an August 15, 2017 review of
NCNHP database indicates no known American alligator occurrence within 1.0
mile of the study area.
Red-cockaded woodpecker
USFWS optimal survey window: year-round; November-early March (optimal)
Habitat Description: The red-cockaded woodpecker (RCW) typically occupies open,
mature stands of southern pines, particularly longleaf pine, for foraging and
nesting/roosting habitat. The RCW excavates cavities for nesting and roosting in
living pine trees, aged 60 years or older, and which are contiguous with pine
stands at least 30 years of age to provide foraging habitat. The foraging range of
the RCW is normally no more than 0.5 miles.
7 October 2017
Natural Resources Technical Report Bridge 080178, Bladen County, NC
Biological Conclusion: No Effect
Suitable habitat in the form of open, mature stands of southern pines used for
foraging, nesting, and roosting were not present in the study area. Additionally,
an August 15, 2017 review of NCNHP database indicates no known RCW
occurrence within 1.0 mile of the study area. Subsequently, the proposed project
will have No Effect on the red-cockaded woodpecker.
Northern long-eared bat
USFWS Recommended Survey Window: June 1— August 15
Habitat Description: In North Carolina, the Northern long-eared bat (NLEB) occurs
in the mountains, with scattered records in the Piedmont and coastal plain. In
western North Carolina, NLEB spend winter hibernating in caves and mines.
Since this species is not known to be a long-distance migrant, and caves and
subterranean mines are extremely rare in eastern North Carolina, it is
uncertain whether or where NLEB hibernate in eastern North Carolina.
During the summer, NLEB roost singly or in colonies underneath bark, in
cavities, or in crevices of both live and dead trees (typically >3 inches dbh).
Males and non-reproductive females may also roost in cooler places, like
caves and mines. This bat also been found, rarely, roosting in structures like
barns and sheds, under eaves of buildings, behind window shutters, in
bridges, and in bat houses. Foraging occurs on forested hillsides and ridges,
and occasionally over forest clearings, over water, and along tree-lined
corridors. Mature forests may be an important habitat type for foraging.
Biological Conclusion: May Affect, Likely to Adversely Affect
The US Fish and Wildlife Service has developed a programmatic biological
opinion (PBO) in conjunction with the Federal Highway Administration
(FHWA), the US Army Corps of Engineers (USACE), and NCDOT for the
northern long-eared bat (NLEB) (Myotis septentrionalis) in eastern North
Carolina. The PBO covers the entire NCDOT program in Divisions 1-8,
including all NCDOT projects and activities. The programmatic determination
for the NLEB for the NCDOT program is "May Affect, Likely to Adversely
AffecY'. The PBO provides incidental take coverage for the NLEB and will
ensure compliance with Section 7 of the Endangered Species Act for five years
for all NCDOT projects with a federal nexus in Division 1-8, which includes
Bladen County, where Bridge 080178 is located.
Wood stork
USFWS Recommended Survey Window: June-September
Habitat Description: Wood storks are known to occur in several coastal North
Carolina counties, and records indicate that they have been breeding in North
Carolina since 2005. Wood storks typically construct their nests in medium to
tall trees that occur in stands located either in swamps or on islands
surrounded by relatively broad expanses of open water. In many areas, bald
8 October 2017
Natural Resources Technical Report Bridge 080178, Bladen County, NC
cypress and red mangrove trees are preferred. During the nonbreeding season
or while foraging, wood storks occur in a wide variety of wetland habitats,
including freshwater marshes and stock ponds, shallow, seasonally flooded
roadside or agricultural ditches, narrow tidal creeks or shallow tidal pools,
managed impoundments, and depressions in cypress heads and swamp
sloughs. Because of their specialized feeding behavior, the most attractive
feeding areas are swamp or marsh depressions where fish become
concentrated during dry periods.
Biological Conclusion: Unresolved
Suitable habitat in the form of inedium to tall trees that occur in stands located
either in swamps or on islands surrounded by relatively broad expanses of open
water was present in the study area. However, an August 30, 2017 survey of the
project area revealed no individuals of wood stork. Additionally, an August 15,
2017 review of NCNHP database indicates no known wood stork occurrence
within 1.0 mile of the study area. Pending surveys by the NCDOT personnel
the biological conclusion for the wood stork remains unresolved.
American chaffseed
USFWS Optimal Survey Window: May-August (1-2 months after a fire)
Habitat Description: American chaffseed generally occurs in habitats described as open,
moist to dryish Mesic Pine Flatwoods and longleaf pine flatlands, Pine Savannas,
Pine/Scrub Oak Sandhills, Sandhill Seeps, and other open grass/sedge-dominated
communities. This herb also occurs in the ecotonal areas between peaty wetlands
and xeric sandy soils and on the upper ecotones of, or sites close, to Streamhead
Pocosins. The species prefers sandy peat or sandy loam, acidic, seasonally moist
to dry soils in sunny or partly sunny areas subject to frequent fires in the growing
season. The plant is dependent on factors such as fire, mowing, or fluctuating
water tables to maintain its required open to partly-open habitat. Most extant
occurrences, and all of the most vigorous occurrences, are in areas subject to
frequent fire. This species is also known to occur on road cuts and power line
rights-of-way that experience frequent mowing or clearing. Soil series that it is
found on include Blaney, Candor, Gelead, Fuquay, Lakeland, and Vaucluse.
Biological Conclusion: No Effect
Suitable habitat in the form of open, moist to dryish Mesic Pine Flatwoods and
longleaf pine flatlands, Pine Savannas, Pine/Scrub Oak Sandhills, Sandhill Seeps,
and other open grass/sedge-dominated communities was not present in the study
area. Additionally, an August 15, 2017 review of NCNHP database indicates no
known occurrences within 1.0 mile of the study area. Subsequently, the proposed
project will have No Effect on the American chaffseed.

Pondberry
USFWS Optimal Survey Window: February-October
Habitat Description: Pondberry occurs in seasonally flooded wetlands, sandy sinks, pond
margins, and swampy depressions. This deciduous, aromatic shrub occurs in
bottomland hardwood forests with perched water tables along inland areas of the
southeastern United States. In the Coastal Plain of the Carolinas, the species
occurs at the margins of limestone sinks and ponds and in undrained, shallow
depressions of longleaf pine and pond pine forests. Known occurrences in North
Carolina occur in the Small Depression Pocosin natural community, grow in soils
with sandy sediments and high-water table, contain high peat content in the
subsurface, and include a prevalence of shrubs due to historically frequent or
intense fires. It generally grows in somewhat shaded areas, but can tolerate full
sun.
Biological Conclusion: No Effect
Suitable habitat in the form of seasonally flooded wetlands, sandy sinks, pond
margins, and/or swampy depressions was present in the study area. However, an
August 30, 2017 survey of the study area revealed no individuals of Lindera
species present. Additionally, an August 15, 2017 review of NCNHP database
indicates no known occurrences within 1.0 mile of the study area. Subsequently,
the proposed project will have No Effect on the Pondberry.
Rough-leaved loosestrife
USFWS Optimal Survey Window: mid-May-June
Habitat Description: Rough-leaved loosestrife, endemic to the Coastal Plain and
Sandhills of North and South Carolina, generally occurs in the ecotones or edges
between longleaf pine uplands and pond pine pocosins in dense shrub and vine
growth on moist to seasonally saturated sands and on shallow organic soils
overlaying sand (spodosolic soils). Occurrences are found in such disturbed
habitats as roadside depressions, maintained power and utility line rights-of-way,
firebreaks, and trails. The species prefers full sunlight, is shade intolerant, and
requires areas of disturbance (e.g., clearing, mowing, periodic burning) where the
overstory is minimal. It can, however, persist vegetatively for many years in
overgrown, fire-suppressed areas. Blaney, Gilead, Johnston, Kalmia, Leon,
Mandarin, Murville, Torhunta, and Vaucluse are some of the soil series that the
plant occurs on.
Biological Conclusion: Unresolved
Suitable habitat in the form of disturbed habitats as roadside depressions,
maintained power and utility line rights-of-way, firebreaks, and trails was present
in the study area. However, an August 30, 2017 survey of the study area revealed
no individuals of rough-leaved loosestrife present. Additionally, an August 15,
2017 review of NCNHP database indicates no known occurrences within 1.0 mile
of the study area. Pending surveys by the NCDOT personnel in the appropriate

survey window the biological conclusion for the rough-leaved loosestrife remains
unresolved.
5.9 Bald Eagle and Golden Eagle Protection Act
Habitat for the bald eagle primarily consists of mature forest in proximity to large bodies
of open water for foraging. Large dominant trees are utilized for nesting sites, typically
within 1.0 mile of open water.
A desktop-GIS assessment of the project study area, as well as the area within a 1.0-mile
radius of the project limits, was performed on August 15, 2017 using 2014 color aerials.
There are two ponds > 2 acres in size located within 1 A miles of the project study area.
A visual survey for nest trees within 660 feet of the project study area was conducted on
August 30, 2017. No nest trees were observed. Additionally, a review of the NCNHP
database on August 15, 2017, revealed no known occurrences of this species within 1.0
mile of the project study area. The project is not expected to have any adverse effects on
the bald eagle.
5.10 Endangered Species Act Candidate Species
As of July 21, 2016, the USFWS lists no Candidate species for Bladen County.
5.11 Essential Fish Habitat
Bladen County is considered an inland county. No Essential Fish Habitat is present in or
within 1.0 mile of the study area.

C` A Pocosin is the full extent (>_ 90%) of its natural landscape size.
C` B Pocosin is < 90% of the full extent of its natural landscape size.
13. Connectivity to Other Natural Areas — landscape condition metric
13a. Check appropriate box(es) (a box may be checked in each column). Involves a GIS effort with field adjustment. This
evaluates whether the wetland is well connected (Well) and/or loosely connected (Loosely) to the landscape patch, the contiguous
metric naturally vegetated area and open water (if appropriate). Boundaries are formed by four-lane roads, regularly maintained utility
line corridors the width of a four-lane road or wider, urban landscapes, fields (pasture open and agriculture), or water > 300 feet wide.

C` D f" D From 10 to < 50 acres
C` E f" E < 10 acres
C` F f" F Wetland type has a poor or no connection to other natural habitats
13b. Evaluate for marshes only.
C` Yes f" No Wetland type has a surface hydrology connection to open waters/stream or tidal wetlands.
14. Edge Effect — wetland type condition metric (skip for all marshes)
May involve a GIS effort with field adjustment. Estimate distance from wetland type boundary to artificial edges. Artificial edges include
non-forested areas >_ 40 feet wide such as fields, development, roads, regularly maintained utility line corridors and clear-cuts.
Consider the eight main points of the compass.
C" A No artificial edge within 150 feet in all directions
C: B No artificial edge within 150 feet in four (4) to seven (7) directions
C` C An artificial edge occurs within 150 feet in more than four (4) directions or assessment area is clear-cut
15. Vegetative Composition — assessment area condition metric (skip for all marshes and Pine Flat)
C" A Vegetation is close to reference condition in species present and their proportions. Lower strata composed of appropriate
species, with exotic plants absent or sparse within the assessment area.
C: B Vegetation is different from reference condition in species diversity or proportions, but still largely composed of native species
characteristic of the wetland type. This may include communities of weedy native species that develop after clearcutting or
clearing. It also includes communities with exotics present, but not dominant, over a large portion of the expected strata.
C` C Vegetation severely altered from reference in composition. Expected species are unnaturally absent (planted stands of non-
characteristic species or at least one stratum inappropriately composed of a single species). Exotic species are dominant in
at least one stratum.
16. Vegetative Diversity— assessment area condition metric (evaluate for Non-tidal Freshwater Marsh only)
C: A Vegetation diversity is high and is composed primarily of native species (<10% cover of exotics).
C` B Vegetation diversity is low or has > 10% to 50% cover of exotics.
C` C Vegetation is dominated by exotic species (>50% cover of exotics).
17. Vegetative Structure — assessment area/wetland type condition metric
17a. Is vegetation present?
�' Yes f" No If Yes, continue to 17b. If No, skip to Metric 18.
17b. Evaluate percent coverage of assessment area vegetation for all marshes only. Skip to 17c for non-marsh wetlands.
C` A >_ 25% coverage of vegetation
C` B < 25% coverage of vegetation
17c. Check a box in each column for each stratum. Evaluate this portion of the metric for non-marsh wetlands. Consider structure
in airspace above the assessment area (AA) and the wetland type (WT) separately.

19. Diameter Class Distribution — wetland type condition metric
�' A Majority of canopy trees have stems > 6 inches in diameter at breast height (DBH); many large trees (> 12 inches DBH) are
present.
C` B Majority of canopy trees have stems between 6 and 12 inches DBH, few are > 12-inch DBH.
C` C Majority of canopy trees are < 6 inches DBH or no trees.
20. Large Woody Debris — wetland type condition metric
Include both natural debris and man-placed natural debris.
C` A Large logs (more than one) are visible (> 12 inches in diameter, or large relative to species present and landscape stability).

22. Hydrologic Connectivity— assessment area condition metric (evaluate for riparian wetlands only)
Examples of activities that may severely alter hydrologic connectivity include intensive
ditching, fill, sedimentation, channelization, diversion, man-made berms, beaver dams, and stream incision.
C: A Overbank and overland flow are not severely altered in the assessment area.
C` B Overbank flow is severely altered in the assessment area.
C` C Overland flow is severely altered in the assessment area.
C` D Both overbank and overland flow are severely altered in the assessment area.
Notes
Small stream swamp system. Downstream wetland system on eastern side of bridge severely impacted by mechanized clearing. Upstream
wetland system more open than would be normal. Historic aerial photos show extensive logging in past.
