1.0 BACKGROUND INFORMATION
The Ballance properties border approximately 5,000 linear feet (LF) of the northern bank of Nahunta
Swamp. Nahunta Swamp flows in a general west-to-east direction along and through the property
boundaries. There are approximately 11,826 LF of streams and ditches within the 56 acres of the
conservation easement. The properties are bounded to the south by Nahunta Swamp and to the west, east,
and north by adjacent landowners.
The Ballance Site Riparian Buffer Restoration Project ("Site") is part of a privately-owned farm that is
used primarily for row crop agricultural, hog production, and pasture. The streams on the Site were
channelized, and riparian vegetation had been cleared in the field areas such that cattle grazing pastures
and row crops extended up to the top of the stream banks. Drainage ditches were excavated in parts of
the Site to provide additional drainage for agricultural production.

1.1 Project Goals and Objectives
This riparian buffer restoration project provides numerous ecological benefits within the Neuse River
' basin. While many of these benefits are limited to the project area, others, such as pollutant removal and
improved aquatic and terrestrial habitat, have more far-reaching effects. Expected improvements to water
quality, hydrology, and habitat are as follows:
' Nutrient removal
• Increased dissolved oxygen concentrations
• Improved stream bank stability
' Reduced water temperature by increasing shading
• Restoration of terrestrial habitat
• Improved aesthetics.

1.2 Project Location
The Ballance site is located in northeast Wayne County, near the Wayne-Greene-Wilson county lines.
The site is approximately 3.0 miles east of the Town of Fremont, and 9.0 miles northeast of the City of
Goldsboro, and west of the intersection of NC 222 and NC 111 in Wayne County, North Carolina (Figure
1).
1.3 Project Description
Prior to restoration, land use within the Site consisted of pastureland for cattle grazing, hog production,
and row crop agricultural production. The majority of the floodplain vegetation had been removed and
fields had been created for crop production and pastureland. The landowner currently has an active hog
operation on the Site. Prior to restoration, the landowner used these fields for the spray application of
swine lagoon effluent. Effluent was spread across the field areas in close proximity to the ditches and
streams on the site. The landowner has now discontinued the use of these fields for application of
effluent and the buffer areas have been placed under a conservation easement.
For analysis and design purposes, the on-site streams were divided into eleven reaches. The reach
locations are shown in Figure 2. The reaches were numbered sequentially, moving from west to east,
with unnamed tributaries carrying a "UT" designation.
Eleven UTs to Nahunta Swamp (UT1 through UT11) drain the majority of the Site. Nahunta Swamp lies
along the southern boundary of the Site and flows in a general west-to-east direction along the property
boundaries. In most areas, only herbaceous species were present along the stream and ditch banks, and
fields were maintained to the top of the streambanks. The lack of riparian vegetation left the channelized
systems open to sunlight and without adequate filtration of agricultural runoff and nutrient loading.
Along reaches that were not regularly maintained, woody riparian vegetation was sparse, existing only in
narrow buffer widths adjacent to the channels. As a result, filamentous algae and other aquatic plants
were common in the channels.
Nahunta Swamp and the smaller channels throughout the Site originate in rural and agricultural areas.
These areas are considered to be at least intermittent channels. The stream lengths of Nahunta Swamp
and the UTs, with restoration approaches are provided in Table 2. The primary objective of the restoration
was to enhance areas of existing riparian buffer vegetation and to reforest the cleared floodplain with
native species along Nahunta Swamp and eleven UTs within the conservation easement. Primary
activities within the Site are designed to preserve plant community assemblages and to enhance and
restore native floodplain vegetation through site preparation and subsequent plantings.

' 1.4 Construction
Prior land use and clearing had already removed the majority of the native floodplain vegetative
' communities along Nahunta Swamp and within the associated floodplain. However, prior to plant
community restoration, remaining invasive vegetation such as privet (Ligustrum sinense), which existed
in small quantities along the stream banks, was cleared by bush-hogging, mowing and cutting with bush
' axes and saws. Cleared areas were then disked to further prepare the soil for planting. Care was taken to
avoid exposure of surficial soils.
Bare-root seedlings of tree species were planted at a density of 680 stems per acre on 8-foot centers for
buffer restoration areas. To ensure meeting vegetation success criteria, enhancement areas were also
planted at 680 stems per acre. Table 3 depicts the total number of stems and percent of species planted.
Planting was performed in February 2006 to allow plants to stabilize during the dormant period and
' establish root systems during the spring season. A total number of 36,950 tree seedlings were planted
during restoration activities. One substitution from the proposed species took place because Hackberry
(Celtis laevigata) seedlings were not available. Overcup Oak (Quercus lyrata) was planted as a
substitute. This species is appropriate for the locale, site conditions, and target community. Overcup Oak
comprised 10 percent of the overall planting. This further necessitated a reduction in laurel oak (Quercus
laurifolia) from the originally proposed 10 percent composition to a 5 percent composition.
' Certain opportunistic species that may dominate the early successional forests within bottomland
hardwood forests have been excluded from riparian buffer restoration efforts with the anticipation that
natural regeneration will occur from existing local species. Opportunistic species consist primarily of red
maple (Ater rubrum), box elder (Ater negundo), and sweet-gum (Liquidambar styraciflua).

2.0 MONITORING RESULTS - YEAR 3 (2008) DATA
The five-year monitoring plan for the Site includes criteria to evaluate the success of the vegetation
components of the project. The specific locations of vegetation plots are shown on the As-built drawing
sheets included in Appendix 1. Two photo point stations are located at each of the six vegetation plots.
The first photo point is for the entire vegetation plot and the second photo point is for the herbaceous plot
at the corner of each quadrant. Site photographs of all photo points are included in Appendix 2.
2.1 Vegetation
The success of this buffer restoration project is dependent upon active planting of preferred canopy
species and volunteer regeneration of the native plant community. In order to determine if the success
criteria have been met, vegetation monitoring quadrants were installed across the Site, as directed by
North Carolina Ecosystem Enhancement Program (NCEEP) monitoring guidance. Six vegetation
monitoring plots were installed on the Site. The number of quadrants required was based on the
species/area curve method, as per NCEEP guidelines. The sizes of individual quadrants are 100 square
meters for woody tree species and 1 square meter for herbaceous vegetation. No plots were established
for shrubs since all planted species were considered tree species. At the end of the growing season,
species composition, density, and survival are evaluated each year.
The density within each of the vegetation monitoring plots for Year 3 is given in Table 4. The initial
density of planted bare root stems, based on the data from the six monitoring plots, was 561 stems per
acre. The average density of bare root stems for monitoring Year 3 is 452 stems per acre. The locations
of the vegetation plots are shown on the as-built plan sheets. Individual quadrant data that includes
diameter, height, density and herbaceous coverage quantities are provided in Appendix 3.

2.2 Areas of Concern
Maintenance requirements vary from site to site and are generally driven by the following conditions:
• Trees planted during wet weather may have difficulty rooting
• Extreme hot, cold, wet, or dry weather during and after construction can limit vegetation growth,
particularly temporary and permanent seed
• The presence and aggressiveness of invasive species can affect the extent to which a native buffer can
be established
• The larvae of herbivorous insects can destroy the trees; so infestations can be extremely damaging.

Monitoring plot 4 had a lower than expected survivability rate for Year 3. The density for Plot 4 was 202
stems per acre, which is below the survivability rate of 320 stems per acre after Year 3. The area has
been inspected and it has been determined that approximately 2 acres surrounding Plot 4 would benefit
from supplemental planting. Supplemental planting in this area will be completed with approximately
200 stems per acre during December 2008 and February 2009, using species that were approved as part of
the restoration plan.
During the monitoring event, morning glory was observed within plots 1 and 3. The morning glory was
not profuse within these plots and was not exhibiting stress on the planted stems at the time of the Site
visit.
Privet was also observed within plots 1 and 2. Only one privet stem on each plot was noted at the time of
the Site visit. However, there is a significant amount of privet established along the banks of Nahunta
Swamp within the project area. To avoid future impacts to planted vegetation from privet, the areas of
privet on the site will be treated during December 2008 and February 2009 to knock the stands back and
provide more time for the planted species to reach heights that will overtop any future privet.
In the future, privet may become a concern due to its former presence along lengths of stream channel
adjacent to the restoration areas. Rivercane and morning glory may also prove problematic as they may
hinder growth of some of the trees due to competition. These potential concerns will be monitored as the
project progresses and matures.
