Dear Mr. Dorney:

This letter transmits the Final Monitoring Report for the Hobucken Bridge Replacement
mitigation monitoring. We have completed all of the required three years of monitoring and have
transferred these lands to the State of North Carolina for permanent management by North
Carolina Wildlife Resources Commission (NCWRC) as North Carolina Game Lands as
described in the Mitigation Plan, Hobucken Bridge Replacement, Atlantic Intracoastal Waterway
Bridge, Pamlico County, North Carolina, dated August 1994 (Revision 2, May 1995 provided
previously). With the transmittal of the enclosed Final Monitoring Report (August 1999-March
2001) Hobucken Bridge Mitigation, Atlantic Intracoastal Waterway Bridge, Pamlico County,
North Carolina, and contingent on no objections being raised by regulatory agencies, we will
consider our mitigation obligation for this project complete.
Our findings regarding compliance with Success Criteria on the monitoring activities are
discussed in the subject report. Based on previous coordination with regulatory agencies it has
been determined that wetland hydrology and soils occur in all 15 two-acre tracts and that
construction compliance has been met. The Year 2 Monitoring Report found that general
vegetative requirements of at least 320 target trees/acre with greater than 50 percent target trees
would be met at the end of the three year monitoring period. However, results from final
monitoring indicated a reduction in the total number of trees on the site. It is expected that
prolonged flooding from wind tides due to hurricanes is a likely cause of this decline. It appears
that the young target trees were affected more than the older pines. While the number of target
trees exceeds the 320 target tree/acre goal, the percent of target trees is 44 percent and does not
meet the >% 50 criteria. Due to the high numbers of non-target loblolly pine and adequate
numbers of target trees (496/acre) it is not considered practical to offset these percentages by
planting of additional target species. Selective clearing of mature trees over time during normal
forestry management would be a more appropriate way to balance the hardwood to pine
distribution on the site. Although specific target species to non-target distribution have not been
fully met, this goal is achievable by future standard NCWRC forestry management practices, and
we therefore conclude that this site is generally successful.

Please consider the findings of the monitoring report and determine if the site is
acceptable to your agency. If found unacceptable please described or identify remediation that
would be required by your agency for your acceptance. Please provide any comments by
November 1, 2005. If we have not received your comments by that date, we will assume that you
have no objections. If you have any questions or would like to discuss the technical aspects of
the monitoring report, please contact Mr. Charles Wilson, Environmental Resources Section, at
[phone]. This same letter is being sent to Dr. Gerald Miller, Project Officer,
Environmental Protection Agency, Region 4; Mr. Pete Benjamin, U.S. Fish and Wildlife Service,
Raleigh Field Office; Mr. Tommy Hughes, North Carolina Wildlife Resources Commission.

COMPLIANCE WITH MITIGATION GOALS
Our primary objective is to restore functional wetland values (primarily wildlife
habitat) in a degraded wetland and provide new state-owned game management lands
to offset wetland and gameland losses as a result of the construction of the Hobucken
Bridge Replacement project. The mitigation plan includes land acquisition, site
preparation and planting, and protection of the site from encroachments. As shown in
Table 3, based on observed site conditions and vegetative sampling, with the exception
of distribution ratios of target to non-target trees stated goals were met to the degree
practical within the monitoring period. It is expected that distribution ratios will also be
met over time by standard forest management practices.

STATUS
OBJECTIVE END OF YEAR 3
1. Restore functional wetland values (primarily wildlife Met
habitat) on 15 acres of presently degraded wetland to
offset 7 acres of wetland losses.
2. Improve wildlife habitat on adjacent 15 acres of presently Met

Explanation: Thirty (30) acres of pine plantation has been acquired, selectively
cleared and developed as planned. Hydrology has been confirmed over the entire
30-acre site. Future land use has been changed form pine plantation to conservation.
The area has been transferred to the State of North Carolina. The Wildlife Resources
Commission (NCWRC) will manage the land as game lands.
Compliance with Mitigation Goals is summarized in Table 3.

***The deed to the State for lands acquired for the Hobucken Bridge Project
("acting through its agency the Department of Transportation") was executed 3 Feb
2003 and is recorded in the records of Pamlico County, Deed Book 395, Page 164.
On March 28, 2003 the Pamlico County Clerk of the Court returned copy of recorded
deed to Mr. Albert E. Joyner, NCDOT, 1430 E. Arlington Blvd. Greenville NC 27858.
Mr. Tommy Hughes indicates that the mitigation land will be included in the next
publication of the NCDWR Game land map book as part of the Goose Creek Game
land.
COMPLIANCE WITH SUCCESS CRITERIA
CONSTRUCTION COMPLIANCE
Construction compliance was found to be acceptable as described in the previous
mitigation report.
4
SUCCESS CRITERIA
Compliance with success criteria is discussed below and summarized on Table 4.
The site will be considered successful if at the end of 3 years, site monitoring indicates
that the following conditions are met:
(1) The site has achieved development of at least 30 acres of palustrine
deciduous/mixed pine habitat, occupied by greater than >50 percent target tree
species, including planted and naturally occurring species. Inclusions of shrub or
emergent marsh are acceptable and will not be subtracted from the goal, with the
exception of any portion that occupies more than 50 percent of the total area.
Expected: Plot sampling indicates that the 30-acre site is a wetland occupied
by 44 percent target trees. Marsh and shrub inclusions do not occupy more
than 50 percent of the site.
Remediation: No remediation proposed. The > 50 percent target species
criteria, is achievable during long term management by proposed standard
forestry practices.
(2) Target trees are present at a density of at least 320 trees/acre.
Exceeded: Plot samples show target tree densities of 496 trees/acre greater
than 320 trees/acre.
(3) No tree species that comprises more than 20 percent of the total trees present
in the mitigation site will be counted as contributing to the 360 target trees/acre goal in
the final mitigation monitoring report.
Acceptable at Year 3: Plot samples, which are expected to represent site
conditions better than the point data, show red maple, a target species (25
percent) and loblolly pine a nontarget species (54 percent) exceed the
distribution criteria. All red maple trees in excess of the 20 percent target
were excluded from 360 target trees/acre goal as described in the July 1997 -
August 1999 August 1999 monitoring report.
Remediation: No remediation proposed. Dominance by red maple and
lobolly pine appears to be consistent with the adjacent reference forest where
these trees are also dominant species and, therefore, is considered a natural
condition in the project area. Based on several years experience with this
site it was determined that a "20 percent criteria" is too restrictive for existing
site conditions and compliance with this criteria is not expected to be practical
at this site. Based on coordination with regulatory agencies we have
modified the original success criteria regarding distribution to allow over 20
percent of a given species but to exclude the counting of any individual target
5
trees greater than 20 percent of total trees as contributing to the 360 target
trees/acre goal in the final mitigation monitoring report. For example if total
trees = 100 and 25 trees are red maple only 20 red maples would be counted
toward the success goal. This supports the objective of tree diversity in
manner that can be practically achieved at this site.
(4) Wetland hydrology (as defined in the 1987 U.S. Army Corps of Engineers
Wetland Delineation Manual) will be documented to exist in all wetland mitigation
sample plots.
Met: Hydrology was confirmed by sampling consistent with 404 wetland
delineation practices in all South Area tracts (6-15) on April 4, 1996.
Saturated soil to the ground surface was present in all areas with a soil
Chroma of 10YR2/1 or 10YR4/1. General observation of scattered areas of
standing water and/or growth of obligate hydrophites throughout the South
Area on July 22, 1997, continue to confirm site compliance with hydrology
requirements. Hydrology was confirmed in all North Area tracts by
observation of standing water, hydric soils, and the presence of obligate
hydrophytes including: Juncus, royal fern, Eleocharis and Ludwigia in each
two-acre tract (1-5) on July 22, 1997. General observation standing water
and/or growth of obligate hydrophites in plots (1-5) on June 17, 1998,
continue to confirm site compliance with hydrology criteria. Delineation was
conducted in all North Area tracts on October 13, 1999. Hydrology has been
documented to occur in all plots, in accordance with plan requirements.

VEGETATION SAMPLING MARCH, 2001
HOBUCKEN BRIDGE REPLACEMENT MITIGATION SITE
HOBUCKEN, PAMLICO COUNTY, NORTH CAROLINA
1.0 Introduction
CZR Incorporated (CZR) completed vegetation sampling at the Hobucken Bridge Replacement
Mitigation Site, Pamlico County Hobucken, North Carolina during March 2001. The following report
details the sampling methods, results, and general field observations for this sampling period.
Hobucken Bridge Replacement Mitigation Site is located in the northeast quadrant of the
Atlantic Intracoastal Waterway crossing by NC Route 304 in Pamlico County, North Carolina. The high-
rise bridge replaces a swing bridge long operated by the U. S. Army Corps of Engineers, Wilmington
District (Corps). CZR was contracted by the Corps to sample vegetation at the wetland mitigation area
associated with construction of the Hobucken Bridge. Previous sampling at the site by CZR occurred
in 1997 and in 1999. Results were discussed in each of the two reports generated after sampling (CZR
1998, 1999). The mitigation area is accessed via a gravel road that turns northwesterly off NC 304
about one quarter mile east of the eastern base of the bridge.
The 30-acre site was a young loblolly pine (Pinus taeda) plantation prior to its conversion to a
mitigation site. The southern portion of the site was first planted in January 1996. In January 1997,
the northern portion was planted with limited replanting in the south. Limited replanting occurred in
the northern section in January 1999. Selected species of woody seedlings were planted in rows
roughly 9 to 13 feet apart throughout the mitigation site. The northern area, approximately 8.5-acres,
was cleared. Stump and root sprouts of several woody species are scattered through this section. A
thick stand of grasses and sedges including a panic grass (Panicum verrucosum) and a beak rush
(Rhynchospora inexpansa) occur in mats one to two feet thick and dominate most of the northern or
open portion of the site. This thick herbaceous layer creates excessive shade for intolerant woody
seedlings.
During the previous sampling most species of live seedlings in this portion of the site were
difficult to detect under the graminoid growth, but a few successful seedlings have now emerged
above this herb stratum. Loblolly pine and red maple seedlings (Acer rubrum) dominate the open
northern section of the mitigation area. Blackberry (Rubes argutus) is becoming more abundant as the
successional status of the open area matures.
In the southern portion of the site, outside the designated no-work areas where no trees were
planted, every other row of pines was cut prior to planting. Debris from the thinning was placed in
adjacent rows under uncut pines. Rows of planted seedlings alternated with rows of older loblolly pine
plantation. Planted pine provides substantial shade over the understory and may constitute a
competitive disadvantage to growth of the hardwood seedlings. Additional cover is provided by stump
and root sprouts of wax myrtle (Cerothamnus ceriferus), red maple, red bay (Persea palustris), and
sweet gum (Liquidambar styraciflua). Greenbriar (Smi/ax rotundifolia), and catbriar (Smilax bona-nox)
are abundant. Density of these species generally increases westward through the southern portion of
the site, at least outside the depression area habitats termed no-work areas. The herb stratum is less
continuous under the pine canopy than in the northern, more open section.
Most no-work areas at the time of the 2001 sampling were shallowly flooded and supported
little or no woody vegetation. These designated no-work areas were avoided during the sampling.
Switchcane (Panicum virgatum), soft rush (Juncus effusus) and scattered-rose mallow (Hibiscus
moscheutos) have made up the characteristic vegetation of these areas in the past. Herbaceous
vegetation was still primarily dormant at the time of the 2001 sampling. Wax myrtle and stunted
loblolly pine were more abundant around the peripheries of open areas.
2.0 Methods
A slightly modified version of the point-centered quarter (often called quarter-point or point-
quarter) method (Bonham 1989) was used to sample tree species (Reed 1988) throughout the
rtitigation area. This method began with the identification to species of the closest individual of a tree
species at least 18" tall, in each of 4 quadrants, around a randomly selected point. The diameter-at-
breast-height (DBH), was measured and recorded for each of four specimens. The diameter of any tree
less than 4.5 feet tall was measured at about 1 /3 of its height (from the ground) and recorded as, Not
DBH (n) in field notes and on data forms. Red bay and sweet bay were not considered trees.
Fifty points were selected for the entire 30-acre site from a random numbers table. The random
sample points were distributed so that 20 points (1-20) were located in the north area and 30 points
(21-50) were located in the south area. All sampling was accomplished outside of designated no-work
areas.
Random points were located in two stages using the site inspection lines through the area.
These inspection lines were established previously in the original sampling year and have been used
annually. Lengths of line segments were summed for these lines separately within the north and south
areas by adding line segments. The total length of each line for the north was divided into 20 equal
parts and by 30 equal parts for the south section. Resulting intervals (approximately 65.5 feet in the
north and 115 feet in the south) along these inspection transect lines from beginning to end were
measured and marked systematically as the beginning points for application of sets of random compass
headings and distances. Fifty randomly selected distances (maximum 200 feet) and compass headings
were located on a map of the site prior to the onset of field work. Distances between points along
inspection transects were measured using a tape. Random distances from these points were paced
using a handheld compass.
Since the original sampling, the long diagonal inspection trail in the northern section has
become overgrown and its original location is no longer discernible. In order to redefine the trail, an
azimuth (250 degrees) was estimated from the map and flagged. The location of this flagged line is
approximately the same as the older trail. The locations of other trails could be determined from signs
of previous survey activity.
Quadrat sampling was used in counting numbers of stems of trees and shrubs by species.
Quadrats 66 feet x 3.6 feet in size were established using randomly selected distances (maximum 200
feet) and compass headings applied from the approximate centers of each of fifteen 2-acre arid
sections. The centers of 2-acre blocks were located by measuring appropriate distances along
inspection corridors and eastward or westward to the approximate center of each block. Each quadrat
was defined from a point at the northwest corner. From this point the southwest and northeast
corners were located by measuring 36 feet south and 66 feet east, respectively. The southeast corner
was located by measuring 36 feet south of the northeast corner. Corners were marked with flagging
tape. One quadrat was established for each of 15, 2-acre grid sections. All sampling avoided
designated no-work areas.
2
Sampling was performed during 26 through 28 March, 2001. Data were recorded in
waterproof field books and later transferred to field sheets generated using Microsoft Excel. The same
data were entered into an Excel spread sheet format supplied by the Corps. Scientific names follow
those listed in a current nomenclature guide (Kartesz 1999). Common names are those in current
regular usage.
3.0 Results
Field vegetation sampling data forms generated in Microsoft Excel 2000 supplied by the Corps
on floppy disks, have been completed and are included as APPENDIX A (Point-Centered Quarter Sample
Data, Hobucken Bridge Replacement Mitigation Site) and APPENDIX B (Quadrat Stem-Count Sample
Data, Hobucken Bridge Replacement Mitigation Site). Copies of these disks are included as a portion
of the product generated by this field exercise.
The approximate locations of sample points used in point-centered quarter samples and the 66
foot by 36 foot quadrat samples used for woody stem counts are shown on a copy of the base map
for the Hobucken Bridge Replacement Mitigation Site generated by the Corps. A copy of the map
showing these locations accompanies this report. The coordinates of the location of point centered
plots and the northwest corner of the stem count plots were taken using GPS.
4.0 Discussion
Vegetation sampling at the Hobucken Mitigation Site was performed to provide data on existing
vegetation conditions. These data will be used by the Corps to determine compliance with vegetation
success criteria. The status of planted seedlings at the mitigation site was judged subjectively based
largely on field observations and generalized observation of raw data. Comments are provided to aid
the Corps in development of potential remediation plans for the site.
Planted seedlings were more difficult to find than during the previous sampling years (1997 and
1999) and seedling mortality was very high throughout the mitigation site. Interspecific competition
between planted and indigenous species as well as predation by deer and unsuitable habitat may be
largely responsible for the lack of survival. However, indications of deer predation did not appear as
abundant during this sampling period compared to previous years. Hurricanes Dennis and Floyd
occurred after the sampling period in 1999. Flooding fro m these two storms, especially Dennis, which
stalled over the Pamlico Sound and caused prolonged flooding of the mitigation site due to wind tides,
may have been another factor that contributed to seedling mortality. Compared to previous years,
2001 sampling indicated a trend of decline in overall density of species, with the exception of loblolly
pine in the northern portion of the site.
Current vegetation conditions indicate continued natural development of loblolly pine and red
maple in the northern portion of the mitigation site. These species will likely form a dominant stratum
within the next two to three years. The stratum will be broken by stands of blackberry. Most
seedlings planted under pines in the southern portion of the site appeared to show low survival.
Unsatisfactory soil and/or moisture conditions and interspecific competition may be partially responsible
for poor seedling success in the southern portion of the site.
Edges around the no-work areas appeared incapable of supporting most planted seedlings.
Almost all planted specimens of cypress (Taxodium distichum), Atlantic white cedar (Chamaecyparis
thyoides), and swamp dogwood (Corpus amomum) seen in these areas were dead. These areas
contained no naturally occurring representatives of these species. Buttonbush (Cephalanthus
occidentalis) also occurred only as a planted species and was not seen alive. The apparent high sulfide
soils in these areas may have been at least partially responsible for the poor survival rates of the above
3
species.
Cypress seedlings in a few sampled sites under the pine canopy and in the open northern
section seem to be doing well. Cypress is an occasional component of the surrounding natural forest.
Seedlings of green ash (Fraxinus pennsyivanica) previously noted as heavily browsed by deer in the
north appeared to be surviving better than most other species but are still few in number. Surviving
representatives of swamp chestnut oak (Quercus michauxii) are also scattered. No laurel oak (Quercus
iaurifoiia) or cherrybark oak (Quercus pagoda) were found in the sample plots. Only one overcup oak
(Q. iyrata) and one willow oak (Q. pheiios) were found. Swamp chestnut oak (Q. michauxil? appears
to be better adapted to the site conditions as it was seen in five of the sample plots. Naturally
occurring water oak persisting from stump and root sprouts was relatively common though other
naturally occurring oaks are absent. Green ash is not a natural component of the adjacent forest. Live
buttonbush, Atlantic white cedar, and swamp dogwood were not seen. Due to similarity of appearance
as seedlings, immature specimens of swamp blackgum (Nyssa bifiora) and blackgum (Nyssa syivatica)
are not readily distinguishable and were lumped as blackgum.
5.0 Conclusions
Planted species of shrubs do not appear to have survived well at the Hobucken Bridge
Replacement Mitigation Site. Planted tree species also continue to show very poor survival. More
recently planted seedlings of laurel oak do not appear to have survived at all. Based on general field
observations the major factors which are most likely to have been responsible for low survival rates
are (1) excessive interspecific competition (low light, etc.) and (2) unsuitable habitat (soil, water
regimes, and storm flooding).
