1.0. Project Summary
1.1. Project Location and Setting
The Tar River Headwaters Wetland Restoration Site (TRHWR) is a full -delivery wetland mitigation project
located in eastern Person County, between Roxboro and Oxford, North Carolina, within the Piedmont
Physiographic Province (Figure 1). The easement comprises 9.98 acres, most of which is drained and
degraded wetlands or former wetlands with hydric soil indicators. The remaining areas include non -hydric
soils, drainage ditches, and a 570 -foot long riparian corridor along an intermittent stream connecting the
TRHWR site to the adjacent Tar River Headwaters Riparian Buffer and Nutrient Offset Mitigation Bank
project. Both projects are designed and implemented by Mogensen Mitigation, Inc. (MMI), and are located
on a 228 -acre farm owned by Roy and Joyce Huff, in the Tar -Pamlico River Basin 12 -digit HUC #
03020101-0102. The Huff Farm property is located at 333 Bunnie Huff Road, Oxford NC 27565. The
access road into the TRHWR site is at Latitude = 36.3913, Longitude = -78.8171.
1.2. Pre -Construction Site Conditions
The TRHWR site was cleared and ditched for pasture use in the 1940s according to the owner, and was
until recently used for grazing cattle. The project involves plugging drainage ditches to restore wetland
hydrology, fencing to exclude livestock, and planting native trees and shrubs to restore a Headwater Forest
wetland ecosystem similar to what occurred prior to site clearing and drainage. The remnant mature trees
left for shade, hydrophytic groundcover plants mixed among the pasture grasses, and plant species recorded
in adjacent forests (on the same soil mapping unit) provide data for the planting plan.
The proposed work will restore approximately 7.65 acres of headwater riparian wetland (6.53 acres
reestablishment plus 1.12 acres rehabilitation) and will generate an estimated 7.28 or more riparian
wetland mitigation credits (RWMC), exceeding the 5.0 RWMC requested by the NC Division of
Mitigation Services (DMS) in RFP # 16-006476. Approximately 1.27 acres with non -hydric soils in
the southeast corner of the mitigation site will also be reforested, and a 100 -foot wide by 570 -ft long
riparian corridor (1.06 acre) extending southeastward along the ditch will connect the TRHWR site to
MMI's adjacent stream restoration and nutrient buffer bank project to the south. Total acreage of the
wetland mitigation site and riparian connector is 9.98 acres.
The proposed wetland restoration and cattle exclusion will reduce soil erosion and nutrient -enriched
runoff from adjacent pasture and cropland within its watershed, and help retain agricultural chemicals
used on these lands. Erosion will be significantly reduced by buffering with native tree plantings. It is
expected to improve water quality and habitat in the receiving tributary and reduce fine sediment
loading which will enhance the overall watershed particularly in the adjacent stream and nutrient
mitigation bank.

1.3. Mitigation Goals and Objectives
Specific project GOALS and corresponding OBJECTIVES include:
GOALS:
• Restore the natural jurisdictional wetland hydro -period to five or more acres of forested
wetland within a nine -acre site;
• Restore forested wetland habitat and improve habitat connectivity between Denny Store
Gabbro Forest (NHP Natural Heritage Area) to the north and the Tar River tributaries;
• Buffer storm water runoff from fecal and other cattle -related pollutants and fertilizer.
OBJECTIVES:
• Plug existing ditches and create sheet flows throughout the site. Aerate soils to reduce
compaction, improve infiltration, and create micro -topography to retain surface flows;
• Preserve the remnant mature Swamp White Oaks (a regionally rare species) for seed source.
Plant appropriate native hardwood trees at a sufficient frequency to establish a diverse
bottomland wetland forest. Treat and/or remove invasive species which may cause problems
for site restoration, including Chinese privet and multi -flora rose;
• Install fencing to exclude cattle and establish a conservation easement to provide permanent
protection on the site.

1.4. Mitigation Components and Attributes
The TRHWR project area contains 6.53 acres of former riparian wetland (ditched and drained, grazed
pasture) that has redoximorphic soil characteristics indicating hydric soils, but no longer has adequate
wetland hydrology based on groundwater gauge data and field observations during 2015-2016. The
drainage ditches were constructed in the 1940s, according to the owner. The project will re-establish
jurisdictional wetlands in this area by plugging the drainage ditches to restore wetland hydrology, fencing
out livestock, controlling invasive species, and planting suitable native tree species. These 6.53 acres of
wetland restoration will generate riparian wetland credits at 1:1 ratio, yielding 6.53 WMU.
Another 1.12 acres in the TRHWR project area has been less effectively drained by the ditches, and still
has sufficient hydrology to meet jurisdictional wetland criteria, based on groundwater gauge data and field
observations during 2015-2016. The project will rehabilitate these areas of degraded jurisdictional wetland
(grazed pasture with reduced hydrology) by plugging ditches to increase hydrology, fencing out livestock,
and planting suitable native tree species. These 1.12 acres of wetland rehabilitation will generate riparian
wetland credits at 1.5:1 ratio, yielding 0.75 WMU. TRHWR project components and mitigations assets are
summarized in Table 1, matching the proposed assets in the Mitigation Plan.
1.5. Construction and As -Built Conditions
Eleven groundwater gauges were installed throughout the site in Feb -Mar 2016 to collect hydrology data
for use in project design, easement boundary selection, water budgeting, and credit determination. A
reference wetland gauge was installed 1,500 ft northeast of the project easement, within the same soil
mapping unit on the Huff property. Some gauges were later relocated during project implementation to
provide better representation of expected hydrologic impacts of the project, and one additional gauge was
added. As -built gauge locations (Feb 2017) are roughly arranged in transects perpendicular to the main
ditch, as recommended by mitigation plan reviewers during field meetings (Figure 2). Ten gauges are
within the proposed creditable reestablishment and rehabilitation areas, and two gauges are down -gradient
from ditch plug #4 in the area of non -hydric soils, not expected to generate wetland credits.
A series of six ditch plugs were constructed to retain rainfall and disperse runoff on the site. Five plugs
along the main north -south ditch include four in the TRHWR area and one downstream in the connector
area in the southeastern portion of the easement (Figure 2). The sixth plug is on the eastern side ditch in
the TRHWR area. Ditch bed segments to be filled were excavated six inches to remove loose material and
plants, to ensure good contact between the fill material and underlying clay. Clay for the plugs was
excavated from the pasture area south of the easement fence, and mixed with sand to achieve liquid limit
and plasticity characteristics as recommended in the mitigation plan. To further enhance ditch plug
stability, the contractor increased the length of plugs on the main ditch, constructing five long plugs (each
plug 65 to 118 ft long) rather than the seven short plugs shown in the mitigation plan. The proposed cluster
of plugs where three ditches converge were merged into one large plug (plug #4). The centerline of each
plug is approximately 2 inches below the adjacent ground surface (old ditch banks), per the mitigation plan.
The elevation drop from the toe of each plug downstream to the crest of the next plug in the wetland
restoration area is 1 to 2 feet (Figures 3 and 4).

In the drained areas, soil aeration and herbicide application for pasture grasses and other invasive species
were conducted prior to planting. Soil amendments and seeding were applied as specified in the mitigation
plan. Existing wetlands, ditch banks, and areas surrounding large native trees were not sprayed. The
wetland rehabilitation and reestablishment areas were planted with eleven species of native trees selected
based on nearby headwater wetland forests, published natural community descriptions (Schafale and
Weakley, 1990; LeGrand, 2007), and recommendations from the plant nursery (Table 5). A few of the oak
species proposed in the mitigation plan were not available; water oak, willow oak, and persimmon were
substituted. Power augers and shovels were used to dig the planting holes for the gallon -size potted trees,
and a tree fertilizer pellet was added to each planting hole. Live -stakes of black willow and silky dogwood
were planted on the ditch plugs and adjacent ditch banks, along with rushes and other plants excavated
from the ditches prior to plugging.
The easement was fenced to exclude cattle using 4 -ft high woven -wire field fence supported on 6 -inch
diameter pressure -treated wooden posts (10 -ft spacing) with single -strand barbed wire on top. Nine CVS
vegetation monitoring plots, each 10 x 10 meters, were installed at representative locations to show
planting densities in the mitigation areas, avoiding areas shaded by large trees (Figure 2). Plot corners were
marked with steel conduit pipe, and planted trees within each plot were mapped and identified following
the CVS protocol (Lee et al, 2008). A soil temperature data logger was installed near the middle of the site
as a supplement to climate data for assessing growing season length.
Construction, fencing, spraying and seeding were completed in January 2017. The ditch segments above
the plugs filled with water within the first few days after construction. The only deviation from the
mitigation plan was the contractor's decision to build the ditch plugs longer than depicted in the mitigation
plan, to ensure plug stability. Tree planting and vegetation plot set-up were completed in February 2017
(Tables 5 and 6). The site was relatively wet due to recent rains during planting, and many of the planting
holes had standing water. The average initial planting density based on the nine CVS plots in the wetland
rehabilitation and re-establishment areas is 409 trees per acre. No invasive species problem areas were
noted at this time. About a dozen mature trees remain in the restoration area; none of these are within the
vegetation monitoring plots.
1.6. Monitoring Plan and Performance Standards
To evaluate mitigation success on the TRHWR site, vegetation monitoring plots will be monitored annually
in accordance with the "Stream and Wetland Monitoring Guidelines" (February 2014). The nine installed
vegetation plots, each 10 x 10 meters, represents 2.8 percent of the planted mitigation area. Vegetation
monitoring will occur between September and early November, prior to the loss of leaves. The vegetation
success criteria are specified in the Performance Standards above. If success criteria are not met, site
maintenance and monitoring will continue until the success criteria are met.
The groundwater monitoring gauges will be downloaded and maintained at least quarterly. Gauge data in
the mitigation credit areas (2 gauges in rehabilitation areas, 8 gauges in re-establishment areas) will be
plotted and evaluated for success based on the mitigation plan performance standard of saturation within
the upper 12 inches for at least 10% of the growing season. The growing season will be determined either
by soil temperature (41'F or greater at 20 inches below the soil surface) or from the USDA WETS Table
data for Person County based on moderate -freeze air temperature data (March 28 to Nov 3 = 220 days).
