1.0 Annual Report Synopsis, Bank Location and Purpose
Greene Environmental Services, LLC (GES) established a riparian buffer mitigation and nutrient
offset bank in Beaufort County, NC under the terms and conditions of the GES Dixon Road
Mitigation Banking Instrument (MBI). The bank, the Dixon Road Riparian Buffer and Nutrient
Offset Mitigation Bank (Bank) is located in the Tar – Pamlico River Basin, Pamlico Sub-Basin
(HUC: 03020104) (Figures 1 and 2). Streams within the Bank discharge via tributaries to
Chocowinity Creek, then to the Pamlico River Estuary at Chocowinity Bay (Figure 3).
1.1 Fifth Annual Report Synopsis
This document is the fifth of five annual reports submitted to NC-DWR as required by the MBI.
Based on a survey of fourteen monitoring plots conducted by GES in October 2023, ten of the
fourteen monitoring plots exhibited adequate stem densities (> 260 stems per acre) of planted
species to meet performance standards (See Section 4.0). The remaining four plots had projected
stem densities of 243 stems per acre, thus one stem (40 stems per acres) shy of the required
minimum in the 10m x 10m plots. Among all monitoring plots, ten of the thirteen species planted
in the Bank were represented. Among all plots the average species richness was 3.1 species and
ranged from six to one species per plot. Five plots met the diversity criterion of four of more
species per plot. Of those not meeting the criterion, four plots had three species, four had two
species and one had only one species of planted stems. The relative density of species in the
plots was highest for sycamore at 38 percent and swamp chestnut oak at 23 percent; the relative
density of all other species was 12 percent or less. Average stem height among all species in the
fourteen plots was 1.6 meters (5.2 feet). Average stem vigor among all 137 stems sampled in the
plots was qualitatively assessed as “good” (stem vigor of 3),
1.2 Bank Location
The Bank is located in western Beaufort County, NC (Figure 1). The street address is 883 Dixon
Road (SR 1138), Chocowinity, NC, 27817. The midpoint of the 16.70-acre Bank (Figure 4)
parcel is approximately 35.456896 x -77.076848; elevation ranges from approximately 27 feet to
35 feet above mean sea level. Access to the Bank parcel is via NC 33 south from Chocowinity
4
approximately 4 miles to Dixon Road then west on Dixon Road approximately 0.8 miles. The
parcel is on the south side of Dixon Road.
1.3 Bank Purpose
The regulatory purpose of the Bank is to provide riparian buffer and nutrient offset
credits for new and existing development in the 8-digit Hydrologic Unit Code (HUC)
03020104 of the Tar-Pamlico River Basin requiring riparian buffer and/or nutrient offset
mitigation in accordance with 15A NCAC 02B .0295 and the corresponding Dixon Road
Mitigation Banking Instrument (MBI). The Bank will also improve water quality within the
Tar-Pamlico River Basin by reducing nutrient and sediment inputs into the watershed. Land-
use within the vicinity of the Bank is primarily agricultural and silvicultural usage, and to a
lesser extent, low-density urban and rural development. Land use within the Bank parcel has
historically been row crop agriculture. There are two unnamed streams and two field ditches
on the parcel containing the Bank (Figures 4), each discharging to Chocowinity Creek or its
tributaries and then to the Pamlico River Estuary. Establishing a native riparian forested
community adjacent to all or portions of these waterways by planting saplings of native trees
species and allowing natural vegetative succession to proceed in perpetuity will reduce
nutrient and sediment loading into those waterways. The Bank has been established pursuant
to the Mitigation Banking Instrument (MBI) developed for the Bank and submitted to NC-
DWR. The Bank has been placed under permanent conservation easement to better ensure
long-term protection of the site (Figure 5).
2.0 Bank Description
The Dixon Road Bank consists of two tracts, each with acreage designated for riparian buffer
credits and nutrient offset credits (Figure 6). Tract 1 consists of Stream 1 with no tributary
streams or ditches present. Stream 1 flows off the Bank parcel toward the northwest to Joe
Branch and then to Chocowinity Creek. Tract 2 consists of Stream 2 with three tributary ditches
(Ditches 3, 4 and 5). Stream 2 flows in a generally northeastward direction off the property to
Chocowinity Creek. Ditch 3 flows from south to north into Stream 2 and Ditch 5 flows from
north to south into Stream 2. Ditch 4 likely has a bi-directional flow pattern with the western
5
portion of Ditch 4 flowing into Stream 2 but the eastern portion flowing east and then north
joining Stream 2 at the eastern boundary of the Bank property. The Ditch 4 offset is not included
in the Bank acreage calculation.
In Tract 1, riparian restoration activities designated for riparian buffer credits along Stream 1
extend from the top of the stream bank landward a maximum of 100 feet on each side of the
stream and paralleling the contour of the stream (Figures 6 and 6-A). The riparian restoration
activities from this 101-foot parallel line outward to a maximum of 200 feet have been
designated for nutrient offset credits. Similarly, in Tract 2, riparian restoration activities along
Stream 2 within 100 feet of the stream has been designated for riparian buffer credits and from
101 feet to a maximum of 200 feet (but not overlapping with Tract 1) has been designated for
nutrient offset credits (Figures 6 and 6-B).
The designation of acreage adjacent to Ditches 3 and 5 has been designated for nutrient offset
credit only, landward from the top of the ditch bank to a maximum of 200 feet but not
overlapping with Tract 1. Table 1 provides an estimate of the acreage and square footage of
mitigation credits for the Bank tracts.

2.1 Project Area – Existing Conditions Prior to Bank Establishment
The Bank is located in the central coastal plain of eastern North Carolina. The landscape in the
vicinity of the Bank is largely rural with the uplands in agricultural and silvicultural land uses
and limited rural housing development. The uplands are dissected with numerous creeks and
swamps; the largest being Chocowinity Creek and its associated swamps (Figures 7 and 7-A).
Prior to European settlement and subsequent conversion to agricultural and forestry production
6
the dominant plant communities were likely Mesic, Mixed Hardwood Forests (Coastal Plain
Subtype) and Coastal Plain Small Stream Swamp (Blackwater Subtype) based on the North
Carolina Natural Heritage Program natural communities classification system developed by
Schafale and Weakley (https://files.nc.gov/dncr-nhp/documents/files/Natural-Community-Classification-Third-
Approximation-1990.pdf). The earliest USGS topographic map indicating land use (agricultural and
forest) in the immediate vicinity of the Bank site was 1951; these conditions are essentially
unchanged for the past six decades.
3.0 Implementation of Riparian Buffer and Nutrient Offset Restoration
In an effort to improve water quality in the Tar River and subsequently downstream in the
Pamlico River and Pamlico Sound estuaries, the NC Department of Environmental Quality
classified the entire Tar-Pamlico River Basin as Nutrient Sensitive Waters (NSW) in the NC
DEQ 2010 Tar- Pamlico River Basinwide Plan (https://deq.nc.gov/about/divisions/water-
resources/planning/basin-planning/water-resource-plans/tar-pamlico-2010). As such, various nutrient
management strategies have been implemented to reduce nitrogen and phosphorus loading in
waters within the basin. One key strategy is to promote the establishment of vegetated riparian
areas along natural and man-made water conveyances (ditches, canals, streams) that are within
or adjacent to lands in agricultural production. Vegetated riparian areas reduce nutrient in
several ways. Permanent vegetated riparian areas remove lands from agricultural production
thus those lands do not receive direct application of fertilizer (chiefly nitrogen, phosphorus
and potassium) and reduce soil erosion thereby reducing the nutrients (principally
phosphorous) that are affixed to sediments. In addition, forested riparian areas separate
agricultural lands from waterways, and with deep-rooted trees and stable soils, intercept,
uptake and sequester nutrients found in groundwater and surfaces waters emanating from
those agricultural lands.
A goal of the Bank is to convert existing agricultural land adjacent to the streams and ditches
into a riparian restoration site. This entailed establishing and preserving, through
conservation easement, a 200-foot wide vegetated riparian zone adjacent to qualifying
streams and ditches in the Bank project area. The post-Bank construction vegetation in this
zone consists of planted native tree species and, through natural succession, colonizing
herbaceous, shrub and tree species.
7
The Bank was planted, manually, with a mix of bare-root saplings of “character tree” species
during March of 2019. A supplemental planting was conducted in March 2020, also with
mix of native species. The saplings were obtained from the North Carolina Forest Service,
Claridge Nursery in Goldsboro, NC. Soil conditions range from moderately well-drained
sandy and clay loams to poorly-drained silt loams, all with low permeability. On-site
conditions affecting the hydrologic properties of the soils included topographic variation
(slopes and flats), drainage ditches, stream channelization, and vegetative cover and land
use. The tree species selected for planting are adapted to these soil and topographic
conditions (Figure 8). Five sapling species were planted initially; these were: river birch
(Betula nigra), sugarberry (Celtis laevigata), sycamore (Platanus occidentalis), black walnut
(Juglans nigra), and swamp chestnut oak (Quercus michauxii). Supplemental planting
introduced box elder (Acer negrundo), mockernut hickory (Carya tomentosa), silky
dogwood (Cornus amomum), American persimmon (Diospyros virginica), yellow poplar
(Liriodendron tulipifera), white oak (Quercus alba), cherrybark oak (Quercus pagoda) and
Nuttall oak (Quercus texana); swamp chestnut oak (Quercus michauxii) was planted
supplementally as well as initially.
The target density of planted trees at the end of the required five-years of monitoring is 260
trees per acre, with no one species comprising more than 50 percent of the total planted trees,
in accordance with the MBI and 15A NCAC 02B .0295 (n)(2)(B). To achieve this target
density, tree saplings were planted in rows approximately twelve feet apart and at intervals of
approximately eleven feet resulting in a projected yield of 335 saplings per acre. Planting at a
density of 335 saplings per acre allowed for a 22% sapling mortality. An estimated 5560
saplings were proposed for planting on the approximately 16.67-acre Bank (Table 2).
Supplemental planting was in areas where survival rates of the initially planted saplings was
low. There were 1425 saplings planted supplementally, thus a total of 7225 saplings were
planted, cumulatively, for an estimated planting density of 433 saplings per acre.
Sycamore was the most frequently planted species (26%); this species along with swamp
chestnut oak (22%) accounted for half of the species planted (Table 3). River birch, sugarberry
and black walnut accounted for 15%, 12% and 8%, respectively. None of the remaining eight
species accounted for more than 3% of the remaining planted saplings. Of note was the
presence of naturally colonizing saplings of American persimmon that survived site-
8
preparation disking in portions of the Bank site.

4.0 Bank Monitoring Results and Maintenance
The Bank was monitored annually for five years. If the vegetative success criteria have met and
approved by NC DWR, this will be the final report. Reports include a vegetative plot summary
(stem counts, stem heights, and stems per acre estimates) monitored in accordance with the CVS-
EEP Protocol for Recording Vegetation (CVS-EEP, v. 4.2). Plots measuring 100 m2 (10m x 10m)
(0.0247 acres) were established at the approximate locations identified on Figure 9. Table 4 lists
the approximate coordinates for the fourteen plots.
In October 2023, the fifth annual survey of the monitoring plots was conducted. Ten of the
fourteen monitoring plots exceeded the target density of 260 stems per acre. Plot stem
densities in the ten plots ranged from 364 stems per acre to 648 stems per acre. Four plots
did not meet the target density; all four had 243 stems per acre, thus one stem shy of the
required stem count of seven to meet the target. Stem density among all plots averaged 425
stems per acre (Table 5).
The most frequently encountered species in the monitoring plots were: sycamore, swamp
chestnut oak and river birch with relative densities of 38%, 23% and 12%, respectively
(Table 5). The calculated stems per acre for these species were 150 for sycamore, 93 for
swamp chestnut oak and 46 for river birch (Table 6). Relative densities of all other species
were less than 10%. White oak, persimmon and mockernut hickory were planted in the
Bank but did not occur in any monitoring plots. Naturally dispersed persimmon is abundant
in portions of the Bank but were not counted as planted stems. Among all plots, species
richness ranged from 1 to 6 species per plot (Table 5). Six plots met the met performance
standard of for diversity as stated in the MBI and 15A NCAC 02B .0295, such that the plots
should contain a minimum of four planted tree species with no one species comprising more
than 50 percent of the total stem count by the end of the five-year monitoring period; eight
plots did not meet this criterion (Appendix A). Five plots met the performance standard of
four or more species per plot; nine plots did not meet this criterion (Species Richness in
Table 5). GES will address this issue in Section 6.0 of this document.
10
Stem heights of all planted species were measured in each plot. The overall average stem
height for stems among the fourteen plots was 1.6 m + 1.2 m (Table 7). Sycamore had the
greatest average total height of 2.3 m + 1.2 m in height. River birch, swamp chestnut oak,
cherrybark oak and Nuttall’s oak all averaged one meter or more in height. All other species
averaged less than one meter in height.
A qualitative assessment of stem status was made for each stem in all plots. In summary, by
species among all plots, indicated that the status for river birch, sycamore, and three oak
species was good (Table 8). The status of all other species was fair to unlikely to survive. In
general, growth for the majority of the planted stems after five years was slow and damage
by deer grazing and rubs was not uncommon.
Appendix A provides stem heights, stem diameters and stem vigor for each individual stem
in all plots. A map of sapling locations was generated for each plot and is provided in
Appendix A. Photographs of each plot were taken from the same plot corner (northwest
corner) and are also provided in Appendix B. Appendix C provides total height data
collected at the end of the 2022 growing season for each stem in all 14 monitoring plots.
Signage was installed at prominent locations along access paths and tract boundaries to identify
the Bank tracts as protected, conservation areas. The signs will be maintained by Greene
Environmental Services, LLC for the duration of the five-year monitoring period. The signs list
prohibited activities within the Bank (e.g., mowing or cutting vegetation, excavation or
deposition of spoil material, vehicular traffic), as well as contact information for Greene
Environmental Services, LLC. Easement boundaries were posted with white, PVC posts to ensure
clear a distinction between the Parcel and adjacent properties. Boundary markers disturbed,
damaged, or destroyed will be repaired and/or replaced on an as needed basis.

Table 8. Sapling vigor by species. Vigor was assessed qualitatively by visual inspection of stems;
vigor categories were: 4 = excellent, 3 = good, 2 = fair, and 1 = unlikely to survive one year. Dead
and missing stems are not reported. Dixon Road Bank, October 2023.
5.0 Comparison of Planted Species in Monitoring Plots From the Year 4 (2022) to the Year 5
(2023) Monitoring Effort
A chief difference found between the fourth year (2022) to fifth year (2023) monitoring effort was a
decrease in the number stems and density per acre of planted species in four monitoring plots (D-5,
D-6, D-8, and D-9); the greatest decline was in Plots D-5 and D-8 (Table 9). These four plots did
not meet the minimum required density of 260 stems per acres. The overall average stem density
among the 14 monitoring plots was 369 stems per acres, thus meeting the stem density criterion.
By species, the greatest stem density changes were declines in sugarberry and Nuttall oak; six other
species declined but only slightly (Table 10). Box elder increased, likely due to remedial planting;
swamp chestnut oak and cherrybark oak increased slightly most likely due to resprouting from the
previous year. Relative densities of the planted species changed little in 2023 because of a somewhat
uniform decline by all species.

6.0 Overall Site Conditions at the Fifth Year (2023) Monitoring Period
In October 2023, the Bank site had been colonized by herbaceous and volunteer woody
vegetation (volunteer persimmon especially) with planted saplings and naturally colonizing tree
and shrub species interspersed. The dominant herbaceous species were goldenrod, mares-tail,
dogfennel and blackberry; shrubs included wax myrtle and groundsel. The tree saplings planted
in March 2019 and 2020 had yet to overtop or shade out the herbaceous vegetation. Prior to
planting, the site was disked leaving a rough textured microtopography which tended to retain
rainwater, these soil conditions were still present in 2023. GES established additional boundary
markers and signage.
Supplemental planting was conducted in 2020 with the purpose of increasing species richness and
density in underperforming portions of the Bank. While generally successful in terms of stem
density in the monitoring plots, species richness was inadequate in the majority of the monitoring
plots and did not meet performance goals. In Tract 1, portions of the tract, especially in areas
west of the stream have been heavily colonized by loblolly pines (Appendix A). In Tract 2, the
northwestern portion of the tract has been heavily colonized by sweetgum. GES will attempt to
alleviate this above-ground competition by manually chopping and sawing small to moderate
stems, and / or injecting herbicide into the stems using a bark injection (“hack and squirt”)
technique on the larger stems.
The soil conditions at the Bank site are not favorable for most planted stems. The dense clay soil
and poor soil fertility apparently inhibit adequate root development; this coupled with heavy
grazing and rubs by deer are likely the reasons for not meeting performance standards. GES will
seek further guidance from NC-DWR to help achieve Bank close-out approval.
7.0 Long-term Management
Greene Environmental Services has established a permanent conservation easement, approved by
DWR, for the Bank. The conservation easement is filed at the Beaufort County, NC Register of
Deeds, Deed Book: 1989, Pages 744-753 and dated May 17, 2019. Signage has been installed at
prominent locations along farm roads and paths to identify the Bank tracts as protected,
conservation areas. The signs will be maintained by Greene Environmental Services, LLC for the
21
duration of the five-year monitoring period. The signs list prohibited activities within the Bank
(e.g., mowing or cutting vegetation, excavation or deposition of spoil material, vehicular traffic,
etc.), as well as contact information for Greene Environmental Services, LLC. Easement
boundaries were identified in the field to ensure clear distinction between the Bank and adjacent
properties. Boundaries were identified by posts, signs and flagging. Boundary markers that are
disturbed, damaged, or destroyed will be repaired and/or replaced on an as-needed basis.
Greene Environmental Services, LLC is responsible for Bank maintenance and monitoring to
ensuring that the terms of a conservation easement are met for five years, beginning in 2019 and
ending in 2023, or until NC-DWR approves a final oversight closeout. GES (Bank Sponsor) will
transfer the conservation easement to a NC-DWR - approved land trust or similar land management
agency (Grantor). The Grantor will assume the responsibilities of maintaining the conservation
easement and the integrity of Bank boundaries using posts, bollards, and signage identifying the
Grantor as the responsible entity. The Grantor will conduct annual sight visits to inspect the Bank
parcel and maintain records to that effect.
8.0 Riparian Buffer and Nutrient Offset Mitigation Potential
The Bank is located in Tar-Pamlico River, Pamlico Sub-basin, HUC 03020104 (Figure 2).
Riparian buffer and nutrient offset mitigation credits are available for development activities
requiring mitigation in this HUC only unless otherwise determined by NC-DWR and/or other
NC Department of Environmental Quality agencies. The acreage of the Bank totals 16.70
acres. Of that total, 6.31 acres yields Tar- Pamlico riparian buffer credits. Nutrient offset
acreage has been adjusted as per guidance from NC-DWR to yield 10.01 acres of nitrogen and
phosphorus nutrient offset credits. Riparian buffer credits are yielded on a per square foot
basis, thus 275,040 square feet (6.31 acres) for the Bank (Table 12). Nitrogen (N) and
phosphorus (P) credits are yielded at a rate of 2,273.02 lbs-N/acre and 146.40 lbs-P/acre,
respectively. Thus, 10.01 acres of nutrient offset acreage yields 22,843.841 pounds of nitrogen
(N) credits and 1,471.32 pounds of phosphorus (P) credits (Table 12). The Bank Sponsor
(GES) maintains and keeps updated, three credit ledgers; one ledger will be for riparian buffer
credits, one ledger for nitrogen nutrient offset credits and one ledger for phosphorus nutrient
offset credits.
22
For this site, all riparian areas proposed in Table 12 for riparian restoration were determined by
NC-DWR to be in agriculture. Therefore, 16.70 acres of riparian restoration credits shown in
Table 12, can be used for either Tar-Pamlico riparian buffer credits or nutrient offset credits, but
not both. The Sponsor (GES) must submit a written request and receive written approval from
NC-DWR prior to any credit conversions or transfers to the buffer and nutrient offset credit
ledgers.
