Brown Marsh Swamp Restoration Site, Robeson County. North Carolina
YEAR 4 (201 l) MONITORING REPORT
EXECUTIVE SUMMARY
The Brown Marsh Swamp Restoration Site (Site) is located one mile east of the North Carolina and South
Carolina state line, and is approximately 15 miles southwest of the Town of Lumberton, in Robeson
County. The Site is situated due east of the intersection of Cotton Valley Road and McCormick Road,
approximately one mile south of Interstate 95. The Site is located within United States Geological Survey
(USGS) Hydrologic Unit and Targeted Local Watershed 03040204037010 (North Carolina Division of
Water Quality Subbasin 03- 07 -55) of the Lumber River Basin and will service the USGS 8 -digit
Cataloging Unit 03040204. The Site was identified to assist the North Carolina Ecosystem Enhancement
Program in meeting its stream and wetland restoration goals.
Primary activities at the Site included 1) stream restoration, 2) wetland restoration, 3) soil scarification,
and 4) plant community restoration. Project restoration efforts provided 5004 Stream Mitigation Units
and 5.0 Nonriverine Wetland Mitigation Units.
Seventeen vegetation plots (10 -10 meters by 10 meters and 7 -20 meters by 5 meters in size) were
established and permanently monumented. These plots were surveyed in August 2011 for the Year 4
(2011) monitoring season. Based on the number of stems counted, average densities were measured at
788 planted stems per acre surviving in Year 4 (2011). In addition, each individual plot met success
criteria. The dominant species identified at the Site were planted stems of silky dogwood (Cornus
amomum), elm (Ulmus sp.), green ash (Fraxinus pennsylvanica), overcup oak (Quercus lyrata),
cherrybark oak (Quercus pagoda), and swamp chestnut oak (Quercus nsichataii), and natural recruits of
red maple (Acer rubrum). No vegetation problem areas were noted during the Year 4 (2011) monitoring
season.
Twenty cross - sections and longitudinal profiles within five 600 -foot reaches were measured for the Year
4 (2011) monitoring season. As a whole, monitoring measurements indicate minimal changes in both the
longitudinal profile and cross - sections as compared to as -built data. The channel geometry compares
favorably with the emulated, stable E/C type stream reach as set forth in the detailed mitigation plan and
as constructed. Current monitoring has demonstrated dimension, pattern, and profile were stable over the
course of the monitoring period. No stream problem areas were noted during Year 4 (2011) monitoring.
Two onsite groundwater gauges and one reference groundwater gauge were maintained for the Year 4
(2011) monitoring season. Monitoring Gauge 2 was inundated /saturated within 12 inches of the surface
for greater than 12.5 percent of the growing season while Gauge 1 was shy of success criteria with
inundation/saturation within 12 inches of the surface for 10.2 percent of the growing season. In addition,
the reference gauge did not meet success criteria with inundation/saturation within 12 inches of the
surface for 3.7 percent of the Year 4 (2011) growing season. No wetland problem areas were noted.
In summary, the Site achieved success criteria for vegetation, stream, and hydrology attributes in the
Fourth Monitoring Year (2011).

YEAR 4 (201 1) MONITORING REPORT
1.0 PROJECT BACKGROUND
1.1 Location and Setting
The Site is located one mile east of the North Carolina and South Carolina state line, and approximately
3.2 miles southeast of the town of Rowland (Figure 1). The center of the Site has a latitude and longitude
of 034° 29' 31.85" N and 079° 16' 26.87" W. The Site is situated due east of the intersection of Cotton
Valley Road (SR 2492) and McCormick Road (SR 2491), approximately one mile south of Interstate 95.
The Site is located within United States Geological Survey (USGS) Hydrologic Unit and Targeted Local
Watershed 03040204037010 (North Carolina Division of Water Quality [NCDWQ] Subbasin 03- 07 -55)
of the Lumber River Basin and will service the USGS 8 -digit Cataloging Unit 03040204 (USGS 1974,
NCWRP 2003). The Site was identified to assist the North Carolina Ecosystem Enhancement Program
(EEP) in meeting its stream and wetland restoration goals.
Directions to the Site from Raleigh, North Carolina, are as follows:
➢ Take Interstate 40 East for approximately 18 miles to Interstate Highway 95 (I -95) South
➢ Take I -95 South for approximately 80 miles to Exit 2, North Carolina Highway 130 (NC -130)
➢ Take a left /travel south on NC -130 for approximately 0.1 mile to Cotton Valley Road (SR 2492)
and turn right
➢ Follow Cotton Valley Road for approximately 2 miles
➢ The project is south of Cotton Valley Road and east of McCormick Road (SR 2491)
1.2 Project Objectives
The primary components of the restoration project included 1) construction of a stable, riffle -pool stream
channel; 2) enhancement of water quality functions within, upstream, and downstream of the Site; 3)
creation of a natural vegetated buffer along restored stream channels; 4) restoration of jurisdictional
nonriverine wetlands in the Site; 5) improvement of aquatic habitat and species diversity by enhancing
stream bed variability; and 6) restoration of wildlife functions associated with a riparian corridor /stable
stream.
1.3 Project Structure, Restoration Type, and Approach
A 20.25 -acre conservation easement has been placed on the Site to incorporate all restoration activities.
The Site contains 5.0 acres of hydric soils, two first -order unnamed tributaries (UTs) to Contrary Swamp
(Northern UT and Southern UT), associated floodplain, and upland slopes. The purpose of this project
was to restore stable pattern, dimension, and profile to the UTs; restore hydrology to drained nonriverine
wetlands; and revegetate streams, floodplains, wetlands, and upland slopes within the Site. The
contributing watershed is characterized primarily by agricultural row crop production and pine
plantation/forest land. Preproject Site conditions consisted of agricultural row crop production. Land use
modifications including the removal of riparian vegetation, straightening and dredging of stream
channels, and ditching of floodplain wetlands resulted in degraded water quality and unstable channel
characteristics (stream entrenchment, erosion, and bank collapse).
The primary goals of this stream and wetland restoration project focused on improving water quality,
decreasing floodwater levels, and restoring aquatic and riparian habitat. These goals were accomplished

1.5 Monitoring Plan View
Monitoring activities for the Site, including relevant structures and utilities, project features, specific
project structures, and monitoring features are detailed in the monitoring plan view in Appendix D. Site
features including vegetation, stream dimension (cross- sections), stream profile and pattern, wetland
hydrology, and photographic documentation were monitored in Year 4 (2011).
2.0 PROJECT CONDITION AND MONITORING RESULTS
2.1 Vegetation Assessment
Following Site construction, seventeen plots (10 -10 meters by 10 meters and 7 -20 meters by 5 meters in
size) were established and monumented with metal fence posts at all plot corners and PVC at each plot
origin. Sampling was conducted as outlined in the CVS -EEP Protocol for Recording Vegetation, Version
4.0 (Lee et al. 2006) ( http: / /cvs.bio.unc.edu /methods.htm); results are included in Appendix A. The
taxonomic standard for vegetation used for this document was Flora of the Carolinas, Virginia, Georgia,
and Surrounding Areas (Weakley 2007). The locations of vegetation monitoring plots were placed to
accurately represent the entire Site and are depicted on the monitoring plan view in Appendix D.
2.1.1 Vegetation Success Criteria
Success criteria have been established to verify that the vegetation component supports community
elements necessary for forest development. Success criteria are dependent upon the density and growth
of characteristic forest species. Additional success criteria are dependent upon density and growth of
"Character Tree Species." Character Tree Species include planted species, species identified through
visual inventory of an approved reference (relatively undisturbed) forest community used to orient the
Site design, and appropriate community descriptions from Classification of the Natural Communities of
North Carolina (Schafale and Weakley 1990) including Coastal Plain Small Stream Swamp and
Florence, be Hutcheson Page 5
Contract No. D06038
Brown Marsh Swamp Restoration Site, Robeson County, North Carolina
YEAR 4 (2011) MONITORING REPORT
Nonriverine Wet Hardwood Forest. All canopy tree species planted and identified in the reference forest
will be utilized to define "Character Tree Species" as termed in, the success criteria. Table 5 below
outlines planted and reference forest species.
Table 5. Planted and Reference Forest Ecosystem
Planted and Reference Forest Ecosystem Character Tree Species
Red maple (Ater rubrum)
Ironwood (Cazpinus caroliniana)
Green ash (Fraxinus pennsylvanica)
American holly (Ilex opaca)
Sweetgum (Liquidambar styraciflua)
Tulip poplar (Liriodendron tulipifera)
Water tupelo (Nyssa Mora)
Laurel oak (Quercus laurifolia)
Overcup oak (Quercus lyrata)
Swamp chestnut oak (Quercus michazzxii)
Water oak (Quercus nigra)
Cherrybark oak (Quercus pagoda)
American elm (Ulmus arnericana)
Success criteria dictate that an average density of 320 stems per acre of Character Tree Species must be
surviving in the first three monitoring years. Subsequently, 290 Character Tree Species per acre must be
surviving in year 4 and 260 Character Tree Species per acre in year 5.
2.1.2 Vegetative Problem Areas
During Year 1 (2008) monitoring, vegetation sampling across the Site was above the required average
density with 476 stems per acre of Character Tree Species surviving; however, five of the seventeen plots
had low densities (plots 12 and 14 -17). Approximately 5 acres of the Site with low densities of stem
survival were replanted at a density of 680 stems per acre in early 2009 prior to Year 2 (2009) monitoring.
These areas appear to be recovering well. No vegetation problem areas were noted during the Year 4
(2011) monitoring season.
2.2 Stream Assessment
Twenty permanent cross - sections within five 600 -foot reaches were established after construction was
completed. Measurements of each cross - section include points at all breaks in slope including top of
bank, bankfull, and thalweg. Riffle cross - sections are classified using the Rosgen stream classification
system. Longitudinal profile measurements of five 600 -foot reaches include thalweg, water surface, and
bankfull; with each measurement taken at the head of facets (i.e. riffle, run, pool, and glide) in addition to
the maximum pool depth.
2.2.1 Stream Success Criteria
Success criteria for stream restoration will include 1) successful classification of the reach as a
functioning stream system (Rosgen 1996) and 2) channel variables indicative of a stable stream system.

YEAR 4 (201 1) MONITORING REPORT
The channel configuration will be measured on an annual basis in order to track changes in channel
geometry and profile. These data will be utilized to determine the success in restoring stream channel
stability. Specifically, the width -to -depth ratio should characterize an E -type or borderline E -/C -type
channel, bank- height ratios indicative of a stable or moderately unstable channel, and minimal changes in
cross - sectional area, channel width, and/or bank erosion along the monitoring reach. In addition, channel
abandonment and /or shoot cutoffs must not occur and sinuosity values must remain relatively constant.
The field indicator of bankfull will be described in each monitoring year and indicated on a representative
channel cross - section figure. If the stream channel is down- cutting or the channel width is enlarging due
to bank erosion, additional bank or slope stabilization methods will be employed. Stream substrate is not
expected to coarsen over time; therefore, pebble counts are not proposed as part of the stream success
criteria.
Visual assessment of in- stream structures will be conducted to determine if failure has occurred. Failure
of a structure may be indicated by collapse of the structure, undermining of the structure, abandonment of
the channel around the structure, and /or stream flow beneath the structure.
2.2.2 Bankfull Events
Documented bankfull events are included in the table below. At least five bankfull events were
documented to date during the Year 4 (2011) monitoring period for a total of twelve bankfull events.

2.2.5 Quantitative Stream Measurements
During the Year 4 (2011) monitoring period 20 cross - sections and longitudinal profiles within five 600 -
foot reaches were measured. Permanent cross - sections and longitudinal profiles are included in Appendix
B; each is graphically depicted for as -built through Year 4 (2011) for analysis. Reach 1 did not have
water during Year 4 (2011) stream measurements; therefore, water surface slopes could not be calculated.
As a whole, monitoring measurements indicate minimal changes in both the longitudinal profile and
cross - sections as compared to as -built data. The channel geometry compares favorably with the
emulated, stable E/C type stream reach as set forth in the detailed mitigation plan and as constructed.
Current monitoring has demonstrated dimension, pattern, and profile were stable over the course of the
monitoring period. Tables for quantitative assessments are included below; these tables include data from
previous years.
2.3 Wetland Assessment
Two groundwater monitoring gauges and one reference groundwater gauge were maintained and
monitored throughout the Year 4 (2011) growing season. Graphs of groundwater hydrology and
precipitation from a nearby rain station (Weather Underground 2011) are included in Appendix C.
2.3.1 Wetland Success Criteria
Target hydrological characteristics include saturation or inundation for at least 12.5 percent within
Trebloc soils (nonriverine wetlands) of the growing season, during average climatic conditions. This
value is based on DRAINMOD simulations for 62 years of rainfall data in an old field stage. These areas
are expected to support hydrophytic vegetation. If wetland parameters are marginal a jurisdictional
determination will be performed for vegetation and soils in these areas (Environmental Laboratory 1987).
2.3.2 Wetland Problem Areas
No wetland problem areas were identified within the Site during Year 4 (2011) monitoring.

Brown Marsh Swamp Restoration Site, Robeson County, North Carolina
YEAR 4 (201 1) MONITORING REPORT
2.3.3 Wetland Criteria Attainment
Monitoring Gauge 2 was inundated /saturated within 12 inches of the surface for greater than 12.5 percent
of the growing season while Gauge 1 was just shy of success criteria with inundation /saturation within 12
inches of the surface for 10.2 percent of the growing season. In addition, the reference gauge did not
meet success criteria for the Year 4 (2011) monitoring season (Table 11). Hydrographs containing
groundwater and precipitation data for each gauge can be found in Appendix C in addition to a graph
depicting annual rainfall at the Lumberton Airport versus 30 -year historic rainfall data collected in
Lumberton (Weatherunderground 2011, NOAA 2004). Groundwater data has been collected through
August 2011 and will continue to be collected for the remainder of the growing season (until November
14, 201 1).

3.0 CONCLUSIONS
The Site achieved the defined (or targeted) success criteria, with saturation (free water) within one foot of
the soil surface for a minimum of 12.5 percent (30 consecutive days) of the growing season at monitoring
Gauge 2 while Gauge 1 was just shy of success criteria with inundation/saturation within 12 inches of the
surface for 10.2 percent of the growing season. In addition, the reference gauge did not meet success
criteria for the Year 4 (2011) monitoring season. A summary of groundwater gauge data is included in
Table 11. Based on the number of stems counted, average densities were measured at 788 planted stems
per acre surviving in Year 4 (2011) (Table 12). In addition, each individual plot met success criteria.
