1.0. Project Background 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 a ditch and intermittent stream
connecting the TRHWR site to the adjacent Tar River Headwaters Riparian Buffer and Nutrient Offset
Mitigation Bank project. Both projects are 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 -Restoration Conditions
The TRHWR site was cleared and ditched for pasture use in the 1940s according to the owner, and was
used for grazing cattle until January 2017 when the conservation easement fence was installed. 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. Remnant native trees left for shade, hydrophytic groundcover plants mixed
among the pasture grasses, and plant species recorded in adjacent natural forests (on the same soil mapping
unit) provided data for the planting plan.
The project 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. 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.
Restoration activities including tree planting, surface flow dispersal, 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. 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 Performance Criteria
The subject watershed HUC #03020101-0102 is designated by NCDEQ as a Targeted Local Watershed
(TLW) for water quality improvement projects, and the Tar River reach within and downstream of this
local HUC is recognized as a Significant Natural Heritage Area (SNHA) for its high diversity of aquatic
life including protected species of river mussels and fishes. The TRHWR project is intended to support
Tar River Headwaters Wetland Restoration Site #97071 MY -2 (2018) Annual Monitoring Report
Person County — Tar -Pam HUC 03020101 Mogensen Mitigation Inc. MMI
these TLW and SNHA designations by improving water quality and habitat on the property and
downstream. Specific project goals and objectives as identified in the TRHWR Final Mitigation Plan
(December 2016) 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 Approach
Prior to restoration, the TRHWR project area contained 6.53 acres of former riparian wetland (ditched and
drained, grazed pasture) with redoximorphic soil characteristics indicating hydric soils, but lacking
adequate wetland hydrology based on groundwater gauge data and field observations during 2015-2016.
Although the drainage ditches are shallow, they have effectively reduced water retention across much of
the site over the past 70 years due to the slow infiltration rate, rapid runoff, and shallow hardpan in these
soils. The project will re-establish jurisdictional wetlands in this area by plugging the drainage ditches to
increase rainfall retention and dispersal, 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.
2.0. Monitoring Methods
Vegetation plots are monitored annually in accordance with current DMS monitoring guidance (June
2017). The nine installed CVS 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 twelve onsite groundwater monitoring gauges (RDS and Hobo) and one offsite reference wetland
gauge are downloaded and maintained at least quarterly. Gauge data in the mitigation credit areas are
plotted and evaluated for success based on the mitigation plan performance standard of continuous
saturation within 12 inches of the ground surface for 10 percent of the growing season. Growing season
based on air temperature at a weather station east of Roxboro is from March 28 to November 3, which is
221 days (from USDA WETS table). MMI installed a Hobo dual -probe soil temperature logger near the
middle of the TRHWR site (beside GW -H) in late January 2017. Soil temperature on the site remained
above 41 F at both 10 -inch and 20 -inch depths throughout February and March 2017. The lowest
temperatures recorded were 42.7 F at 10 inches and 45.4 F at 20 inches. Based on soil temperatures
remaining above the USDA -designated temperature for plant physiological activity, March 1 is used as the
start of the growing season, based on field discussions with DMS and USACE. The revised growing
season length is thus 248 days, and the groundwater hydrology success criterion is 25 days.
The conservation easement perimeter fence and ditch plug integrity will be monitored visually and
documented with photo points.

3.0. Current Conditions Summary
MMI scientists made several visits to the TRHWR site between March and November 2018 to collect
gauge data and evaluate the condition of the ditches, ditch plugs, and planted and volunteer trees. The CVS
vegetation plot data collection was performed in early October. Seven of the nine CVS plots had 8 to 12
surviving stems (planted plus volunteers) and met the 320 stems per acre success criteria (Tables 6 and7).
Outside of the CVS plots, planted stem survival looks generally good throughout the site, with an estimated
10 to 20 percent apparent mortality. Leader die -back is common on many of the taller seedlings, especially
on tulip poplar and river birch, but most of the trees exhibiting leader die -back also had vigorous basal
sprouts. There are scattered small areas with tree densities less than 320 stems per acre, but none
exceeding the "problem area" size threshold, and no "low woody density" areas or "invasive exotic"
problem areas were designated this year. Groundcover vegetation is excellent throughout, with both treated
areas (non -wetland and drained wetland) and non -treated areas (existing wetland) showing dense and
diverse herbaceous cover. Small unflagged trees outside of the CVS plots remain difficult to see due to the
dense groundcover.
All ditch plugs appear to be stable and performing as designed, despite 8 inches of rainfall during
Hurricane Florence in mid-September. Survival of planted trees, live -stakes, and herbaceous cover on the
plug slopes and tops appears to be providing good protection; no significant erosion on the plugs was
observed. Ponding behind all of the ditch plugs was evident during spring and intermittently during
summer and fall.
Twelve groundwater gauges (A through L) on the project site are roughly arranged in four transects
perpendicular to the main ditch, as recommended by mitigation plan reviewers during field meetings
(Figure 2). Three gauges (A, H and J) are within existing wetland rehabilitation areas, seven gauges (D, E,
F, G, I, L, and K) are within the drained wetland reestablishment areas, and two gauges (B and C) are
downslope from ditch plug #4 in areas not expected to generate wetland credits. Wetland hydrology
success for the TRHWR site is based on saturation within 12 inches of the ground surface for 10% of the
248 -day growing season (March 1 to November 3). The gauges measure the free water table depth and do
not account for capillary fringe saturation which can extends well above the free water table in fine -
textured soils(https://vemonjames.ces.ncsu.edu/eleventh-annual-on-site/soil-wetnesso.
Rainfall in 2018, relative to the 30 -year normal values (30th to 70th percentiles), was normal in January, low
in February, normal in March, and above normal from April through June and from August through
November (Figure 5). In 2018 all 13 gauges (ten in the mitigation credit area, two outside the credit area,
and one off-site reference gauge) exceeded the minimum of 25 consecutive days for hydrologic success
during the early part of the growing season, with consecutive day saturation periods ranging from 64 to 101
days (Figure 6).
Soil temperature data for 2018 support the accepted growing season start date of March 1. Soil temperature
remained above 41 F from January 28 onward, and the lowest recorded soil temperature after March 1 was
44.3 F on March 15. The lowest recorded soil temperature in 2018 was 36.2 F during January 9-10 at 10
inches deep.
