EXECUTIVE SUMMARY
The Roquist Wetland Restoration Site (hereafter referred to as "the Site") is located within Bertie
County, North Carolina within Hydrologic Unit 03010107 of the Roanoke River Basin. The Roquist
wetland forms the headwater basin of Roquist Creek and Indian Creek.
The Site encompasses 3,926 acres (ac) and is almost entirely (99%) comprised of an extensive wetland
system. The drainage area is approximately 13,700 ac. The land surrounding the wetland is comprised
mostly of agricultural crops and pine plantations. The Site itself had been timbered for nearly a century.
Timbering in the Roquist wetland required elevated logging roads to be constructed throughout the Site.
These roads included ditches adjacent and perpendicular to the logging roads. 12 miles (mi) of logging
roads existed on the Site pre-construction.
Originally, Phase I of the Roquist project consisted of restoration of 52 ac of previously ditched and filled
nonriverine wetlands, preservation of 3,776 ac of nonriverine wetlands, preservation of 45 ac of
uplands, and preservation of 3,660 ft of stream on Jack's Branch. However, due to fiscal constraints, the
restoration design for Phase I was scaled back to include 45.2 ac. The restoration efforts included filling
roadside ditches, grading logging roads to existing wetland elevations, and planting of native vegetation.
Construction took place between April 30, 2007 and January 16, 2008. Final acceptance was given on
February 6, 2008. Restoration efforts will improve water storage, pollutant removal, aquatic/wildlife
habitat, and recreation. The post-construction site conditions are further detailed within this report.
Monitoring of the wetland restoration efforts will be performed for 5 successful years. Monitoring for
two wetland components, hydrology and vegetation, will take place. Groundwater hydrology will be
monitored with automated groundwater gauges. These gauges will record water level data daily.
Hydrologic success criterion consists solely of the restored area meeting the requirements to be
classified as a wetland. These requirements are detailed within this report.
Vegetation plots were set within the restored area. These plots will be inventoried during each growing
season within the 5 year monitoring period. All but two plots were set to coincide with the groundwater
gauge locations. Wetland vegetation survivability deals with the number of live plantings and is further
detailed within this report.
Figures 4 and 5 within this report summarize the mitigation areas, vegetation plot and groundwater
gauge locations, and the planting zones.
Future visitors of the Site should be aware of the presence of wild hogs, which is evidenced by footprints
found throughout the Site, when completing monitoring tasks. The wild hogs may also contribute to the
destruction of plantings installed.
In the event that vegetation and/or hydrology success criteria are not fulfilled, appropriate contingency
measures will be implemented in coordination with the Resource agencies.

Mitigation Plan Roquist Wetland Restoration Site
1.0 Introduction
The North Carolina Ecosystem Enhancement Program (EEP) developed a regional wetlands
mitigation site in eastern North Carolina. The Roquist Wetland Restoration Site is located in
western Bertie County south of Lewiston-Woodville, North Carolina within Hydrologic Unit
03010107 of the Roanoke River Basin (Figure 1).
The Roquist Wetland Restoration Site is a unique ecosystem hosting prime examples of
nonriverine wetland communities in large, nearly intact tracts. The Site encompasses
3,926 ac positioned on the interstream divide of the Roanoke and Cashie Rivers.
Historically, the Site was known as a pocosin primarily for its geologic setting rather than its
vegetative composition. The Site is almost entirely comprised of Nonriverine Swamp
Forest and Wet Hardwood Forest Communities with relatively smaller portions of Mesic
Mixed Hardwood Forest Communities (Schafale and Weakly 1990) positioned along the
margins of the vast flat. Historic activities in the Site include intensive logging and some
conversion of wetland hardwood forests into pine plantation. These efforts required
constructing elevated roads for access into the area in addition to ditching in order to drain
the site for ease of timber removal. Although the Roquist Wetland Restoration Site has
been heavily timbered for nearly a century, there remains approximately 390 ac of high
quality old growth forest harboring specimens of a rare 95+ years of age. The old growth
forest forms a contiguous Nonriverine Swamp and Wet Hardwood (Schafale and Weakly
1990) stand that is uncommon to be of this age and size.
2.0 Project Summary
Due to the magnitude of the restoration effort for the Roquist Wetland Restoration Site,
the project was divided into two major phase's (hereafter referred to as Phase I and Phase
11). The restoration components for Phase I of the Roquist Wetland Restoration Site
consisted of restoring ditched and filled wetlands and preserving existing Nonriverine
Swamp Forest, Nonriverine Wet Hardwood Forest, and Mesic Mixed Hardwood Forest
Communities. The Roquist Wetland Restoration plan (August 2005) proposed restoration
of 52 ac of wetlands. However, due to fiscal constraints, Phase I was scaled back to include
only 45.2 ac of restored wetlands. Specifically, Phase I consisted of the following
components:
• restoration of 45.2 ac of previously ditched and filled nonriverine wetlands
• preservation of 3,776 ac of nonriverine wetlands
• preservation of 45 ac of uplands
• preservation of 3,660 ft of stream
The project activities, timeline, and contacts are summarized in Appendices A and B.

Mitigation Plan Roquist Wetland Restoration Site
2.1 Pre-Construction Site Conditions
2.1.1 Land Use
The Site encompasses 3,926 ac positioned on the interstream divide of the Roanoke and Cashie
Rivers, drainage area of approximately 13,700 ac. The Roquist wetland forms the headwater
basin of Roquist Creek and Indian Creek. Land use surrounding the wetland is mostly comprised
of agriculture crops and pine plantations. The Site itself lies almost entirely within the limits of
the wetland system with peripheral portions of the Site extending into uplands. Ninety percent
of the Site is 42 feet (ft) above mean sea level (msl) with a gradual rise to 54 ft above msl
forming the rim. The highest elevation reaches 78 ft above msl and is located within the small
stream basins (Jack's Branch) located in the northern portion of the Site.
Timber records from International Paper indicate the Roquist Wetland Restoration Site has been
timbered for nearly a century with the oldest stands being established in 1905 and 1910.
However, the majority of the existing forest within the Site ranges from twelve to sixty years of
age. The most recent timbering activities occurred in 2003 with a final 927 ac harvested from
April to October. In addition, logging records reveal a pine plantation was established within
timbered wetlands near the western entrance of the Site. Timbering in the Roquist wetland
required elevated logging roads to be constructed throughout the Site to aid in removal of
timber. Aerial photographs of the Site indicate that five miles of logging roads were present as
early as 1964. These roads include ditches located adjacent and perpendicular to the logging
roads ranging in width from 2 to 25 ft. Prior to construction, 12 mi of logging roads traversed
the Site including a small segment in the north. Figure 2 is an example of the logging roads and
adjacent ditches that were in place prior to construction.
Figure 2. Logging Roads
Mitigation Plan
2.1.2 Water Resources
Roquist Wetland Restoration Site
There are three jurisdictional streams located within the Site. These streams include Jack's
Branch, Roquist Creek, and Indian Creek (Figure 1). On the USGS topographic map Jack's Branch
appears to have a continuous channel through the Roquist wetland and connecting with Indian
Creek. Historically, this may have been accurate but field investigations (2003) of Jack's Branch
revealed no continuous channel through the Roquist wetland, but Jack's Branch does have 4,000
ft of clearly defined channel in the northern section of the Site. Non-jurisdictional surface waters
observed within the Site include drainage ditches located adjacent to and perpendicular to the
existing logging roads.
The Roquist Wetland Restoration Site is almost entirely comprised of an extensive wetland
system. Specifically, the wetland accounts for 99%, or 3,881 ac of the Site. Based on field
observations, the wettest hydrology is localized within the center of the Site where the lowest
recorded elevations (41.5-42 ft above msl) occur. These areas experience more frequent and
deeper inundation when compared with the adjacent wetland areas. Presumably this is due to
the influx of water from the surrounding uplands. Relatively drier wetlands are located along
the margins of the Roquist wetland where elevations are slightly higher (43-45 ft above msl)
than elevations within the central flat. Environmental scientists of HSMM of North Carolina, Inc.
(HSMM) delineated the wetland/upland boundary along the proposed mitigation areas from
October 20 to 28, 2003 using the methods described in the 1987 U.S. Army Corps of Engineers
(USACE) Manual, Field Guide for Wetland Delineation. The jurisdictional determination was
received from the USACE on February 11, 2004 (Appendix A).
2.1.3 Habitat
The Classification of Natural Communities of North Carolina, Third Approximation (Schafale and
Weakley 1990) was used to categorize the Site's natural plant communities. Consequently, the
following natural communities were identified within the 3,926-ac Site: Nonriverine Swamp
Forest, Nonriverine Wet Hardwood Forest, and Mesic Mixed Hardwood Forest (Coastal Plain
Subtype). These communities are listed in the North Carolina Natural Heritage Program's
(NCNHP) database for Natural Communities within the Roquist wetland. Floristic communities
that could not be classified according to Schafale and Weakley (1990) included pine plantation,
old-field community, and clear-cut areas (early succession) (Figure 4, Table 1).
Old-field communities within the Site include early stages of Nonriverine Swamp and Wet
Hardwood Forests and accounted for approximately 25% of the Site's plant community. These
communities were classified as those that have been intensively logged within 1 to 10 years of
the investigation (October 2003). Clear-cut communities were classified as areas that had been
intensively logged within one year of the Site investigation. Clear-cut communities included
approximately 32% of the Site's plant community.

3.1 Wetland Restoration
Wetland restoration efforts for Phase I of the Roquist Wetland Restoration Site included 45 ac of
nonriverine wetlands (see Appendix H for Record Drawing produced at completion of
construction). The restoration efforts consisted of grading the existing logging roads and spoil
areas to their original wetland elevations, filling the existing roadside ditches to their original
wetland elevations, and soil preparation (ripping/disking) of the restoration areas.
Additionally, impervious dikes were placed in select locations within the restored ditch areas to
restrict ground water movement through backfilled ditches. Prior to construction cross sections
were surveyed approximately every 1,000 ft in the restoration areas in order to compare existing
natural elevations to road, ditch, and spoil area elevations. Natural wetland elevations
determined by these cross sections were used as the design elevations in the restoration areas.
After completion of construction, as-built surveys were conducted in order to ensure grading
conformed to the design elevation (Appendix H).
All soils utilized for construction within the restoration area consisted of in situ soils and organic
debris generated onsite during clearing and grading operations. Rock material, most likely rip rap
imported during original road construction, was discovered during excavation of Road Al. This
material was excavated to an elevation 2 feet below the design elevation and backfilled with in
situ soils generated from excavation on other roads.

Roquist Wetland Restoration Site
The wetland restoration area was planted with trees in the form of bare-root stock. Planting was
performed between December 11, 2007 and January 16, 2008 using a minimum stem count of
331.5 stems per acre. The restoration areas were planted with either a Nonriverine Swamp
Community or Nonriverine Wet Hardwood Community, according to the Plant Plan on Sheet 2B
in the Record Drawing (Appendix H, Figure 5). The plant community planted in the restoration
areas was originally to be determined by the existing plant community surrounding that location.
In the restoration areas where the surrounding plant community was a clear cut or old field
community, the plant community planted was to be determined by the plant community that
existed prior to timbering. The approved Issued for Construction plans mistakenly had the
planting zones labeled backwards and therefore, was planted as such. Due to the fact that many
of the species are shared between the two planting types and that that the two types share
similar abiotic variables these plantings are likely to survive. There were a total of 33.1 ac of Type
I planting (Nonriverine Swamp Community) and 12.1 ac of Type II planting (Nonriverine Wet
Hardwood Community). Species planted for each of the communities are shown in Table 3,

Mitigation Plan Roquist Wetland Restoration Site
3.2 Wetland Preservation
The wetland preservation component for the Roquist Wetland Restoration Site consists of
preserving 3,776 ac. Of this, 390 ac are high quality wetland preservation. The total preservation
acreage included areas that contained stands established before 1993 (1,520 ac), areas that have
been logged since 1993 (2,210 ac), and a ten year old pine plantation (established in 1993) (46
ac). Of the stand established, before 1993, 390 ac make up an area of high quality wetland
preservation due to the presence of a rare, old growth forest harboring specimens of 95+ years
of age. Although the logged areas were absent of mature vegetation at the time of initial
observation (2003), they are considered an essential part of the existing high quality forests. By
the time of construction, these areas were already 4+ years into succession and demonstrated
good natural ability. These areas will ultimately contribute to the formation of an extensive
wilderness area through the discontinuation of timber practices and the process of natural
regeneration within the Site.
3.3 Upland Preservation
The upland preservation component for the Site consisted of preserving 45 ac of existing Mesic
Mixed Hardwood Forests and clear-cut uplands. These areas were located along the western and
northern boundaries of the Site.
3.4 Stream Preservation
The stream preservation component consists of 3,660 linear feet of channel on Jack's Branch in
the northern portion of the Site. This stream is on a site that contains habitat for 4 Federal
Species of Concern and the area upland of the stream is a High Quality Wetland Preservation
area which makes this a viable stream preservation reach. The portion of the stream within the
project boundary is protected by the conservation easement surrounding it. There is a small
portion of Jack's Branch that does not have a 50 ft buffer on both sides of the stream within the
easement as can be seen by the gap in the stream preservation area in Figure 4.
4.0 Monitoring Plan
Monitoring of wetland restoration efforts will be performed for five successful years following
the conclusion of construction and planting (February 2008). Monitoring is for two wetland
components, hydrology and vegetation.
10
Mitigation Plan
4.1 Hydrology
Roquist Wetland Restoration Site
Initially, 11 groundwater gauges were installed in 5 locations on the Site and data has been
collected since May 11, 2005. Currently, there are 12 gauges in 7 locations throughout the Site
(Sheet 4 and 6-7 of Record Drawing, Appendix H). Ten of the current twelve gauges are set in
pairs with one being located in a reference wetland adjacent to the restoration area and the
other inside of the restoration area. These gauges record data once daily and will be in operation
throughout the year. Data will be retrieved monthly, throughout the growing season to provide
effective monitoring and assessment of success criteria for wetland hydrology during the five-
year monitoring period.
Remote Data Systems, Inc. model Ecotone TM WM Series automated groundwater monitoring
gauges were installed within the reference wetlands and in the restoration areas on May 10,
2005 in accordance with specifications in the . Corps of Engineers' Installing Monitoring
Wells/Piezometers in Wetlands (WRP Technical Note HY-IA-3.1, August, 1993). These gauges will
continuously record water level data along a 40-inch gradient once daily.
Gauge data collected thus far has been plotted against precipitation data obtained from the NC
Climate Office (Appendix D). The precipitation data is from two stations: the Peanut Belt
Research station (ID:LEWS) and the Lewiston station (ID:314692). In these plots it can be seen
that the reference wetlands have a higher water depth than the restoration areas the majority of
the time. There are a few instances where the opposite occurs in the period after construction
was complete. Large drops in water depth may be a result of a record drought experienced
during 2007. Over time it can be seen that the water depth in the restoration areas are becoming
greater and approaching the reference wetland depth. It should be noted that gauges in restored
areas had to be removed and then reinstalled after grading.
4.1.1 Hydrologic Success Criteria
Wetland hydrology success criterion will be satisfied in the restoration areas during average
climatic conditions when saturated soil conditions occur within 12 in of the ground's surface for
a minimum of 12.5% of the growing season, or if the hydro period in the restoration areas is
within 20% of the reference wetland's hydro period during drought conditions.
4.2 Vegetation
HSMM established ten quantitative sampling plots (10 meter (m) x 10 m) for vegetation on April
15, 2008 in the wetland restoration areas. The plots were set in accordance with specifications
in CVS-EEP Protocol for Recording Vegetation, All Levels of Plot Sampling (Version 4.0, 2006) and
at the direction of EEP. Seven of the ten plots were placed so that a groundwater gauge was just
inside of the plot edge (Appendix H). Photos were taken on April 15, 2008 at each sampling plot
at to provide a visual record of vegetation development over time (Appendix E). Vegetation
plots will be inventoried during each growing season and will be in accordance with CVS Level II
protocol. Baseline monitoring was completed October 29, 2008. The collected data can be found
in Appendix F along with the established photo stations in Appendix G.
11
Mitigation Plan Roquist Wetland Restoration Site
4.2.1 Vegetation Success Criteria
Wetland vegetation success criterion is defined by a minimum mean density of 320 trees per
acre of approved target species surviving for the first three years (USACE 1995). The required
success criteria will decrease by 10% per year after the third year to 290 stems per acre for year
four and 260 stems per acre for year five. Vegetation success criteria apply to the Nonriverine
Swamp Community and the Nonriverine Wet Hardwood Community that has been planted
within the Roquist Wetland Restoration Site.
As can be seen from the collected baseline data in Appendix F, there are vegetative plots where
no or only a few planted woody stems were found. This already does not meet the year 1
success criteria discussed in the following section and a contingency plan will need to be
enforced. This data also shows that almost every plot has strong, healthy bare root planting
species present that are not a shared species between the two planting types. This supports the
statement made in section 3.1 about either planting type having a high chance of survivability in
any of the restoration areas.
It should be noted that wild hogs are present on this Site and could contribute to the
destruction of planted vegetation.
5.0 Contingency Plan
In the event that vegetation and/or hydrology success criteria are not fulfilled, appropriate
contingency measures will be implemented in coordination with the Resource Agencies.
Examples of such actions include replanting and extension of the monitoring period if
community mitigation types do not fulfill minimum number of planted stems per acre
requirements. If exotic invasive plant species are of concern, appropriate measures will be used
to control for them. Hydrologic contingency will require consultation with hydrologists and the
Resource agencies in the event that predicted hydrology is not achieved during the monitoring
period. Recommendations for altering hydrology to establish wetland hydrology will be
implemented and monitored until the hydrology success criteria are achieved.
6.0 Mitigation Values
The objective of the Roquist Wetland Restoration Site is to enhance, restore, and preserve 3,823
ac of the Roanoke and Cashie Rivers' headwater ecosystems. The mitigation components should
be viewed from the perspective of their cumulative contribution to the overall value of the
ecosystem rather than their individual values. The nonriverine ecosystem to be protected in
perpetuity not only provides valuable habitat to a diverse assemblage of flora and fauna but also
serves as a contiguous wildlife corridor. Wetland values that will be increased by the mitigation
efforts for the Site include water storage, pollutant removal, aquatic/wildlife habitat, and
recreation. The types of natural communities available for mitigation within the Site are listed in
Table 3, Mitigation Credits.
12
Mitigation Plan
Roquist Wetland Restoration Site
The Roquist Wetland Restoration Site will be managed by EEP. All mitigation credits and the
credit release schedule for the Roquist Wetland Restoration Site will be consistent with the July
22, 2003 MOA between the NCDENR, NCDOT, and USACE.
