EEP Project No. 27 iii UT to Bear Swamp Creek Restoration Site
1.0 EXECUTIVE SUMMARY
The Unnamed Tributary (UT) to Bear Swamp Creek Stream Mitigation Site (hereafter referred to as the
"Site") was constructed for the North Carolina Ecosystem Enhancement Program (EEP) to provide
compensatory stream mitigation in the Tar/Pamlico River Basin. This stream restoration project is
located on an unnamed tributary to Bear Swamp Creek at the Murphy Hay Farm just north of the Town of
Louisburg. This project involves the permanent exclusion of cattle from the stream, stabilization of
eroding stream banks, installation of cross-vane structures for habitat, and the planting of a forested
riparian buffer.
The following report summarizes the monitoring activities that have occurred in the past year (the fifth
year of project monitoring) at the Site. Site construction began and was completed in July 2002. As-built
surveys for the Site were performed in August 2002. First year monitoring was conducted in September
2003, and has continued through the current fifth year of monitoring. The Site must demonstrate
vegetative criteria success and a stable restored stream channel for a minimum of five years or until the
Site is deemed successful. The following paragraphs summarize the results of the 2007 year monitoring.
Vegetation Monitoring
Vegetation monitoring for Year 5 was performed based on the Carolina Vegetation Survey (CVS) Levels
1 and 2 (Lee et al. 2006). CVS methodology determines density and survival of planted species, and
individuals resulting from natural regeneration. Plot locations are consistent with previous years and plot
size consists of 5m x 20m. Based on recommendations by EEP, Plot 4 was not surveyed in the current
monitoring Year 5. The taxonomic standard for vegetation follows Flora of the Carolinas, Virginia,
Georgia, and surrounding areas (Weakley, 2007).
Vegetation success criteria for the forested riparian restoration areas are based on a minimum survival of
260 stems per acre of planted species at the end of Year 5. Volunteer woody vegetation will also be
included in the survivability calculations. Based on the fifth year surveys, the average count of the
surviving planted species is 293 stems per acre. If volunteer species are included, the total number of
stems increases to 8690 stems per acre. The Site meets and exceeds the established success criteria for
vegetation based on the survival of the planted species.
The apparent cause of mortality for some planted species is competition from fast-growing woody
species, principally Pinus taeda, and from large herbs such as Sorghum halapense, Solidago sp., and
Eupatorium capillifolium. Other early successional species in abundance on the site include red maple
(Acer rubrum) and sweet gum (Liquidambar styraciflua). The heavy loblolly pine colonization is a
continuing nuisance as pines compete with the more desirable species for light and nutrients. Drought
conditions ranging from moderate to extreme have afflicted Franklin County for the duration of the
growing season and may be responsible for some species mortality.
Stream Enhancement Monitoring
Success criteria for the restored stream reach has been established to confirm that no significant changes
have occurred to the dimension, pattern, profile, and bed material over the 5-year monitoring period.
Location surveys of the constructed features were conducted to verify the performance of the stream. A
total station survey was performed to describe the stream longitudinal profile and five permanent stream
EEP Project No. 27 1 UT to Bear Swamp Creek Restoration Site
cross-sections (3 riffles and 2 pools). A modified Wolman pebble count and assessment of the
constructed features was also undertaken.
Overall, the stream channel bed form is stable. However, many of the grade control structures (rock
vanes) in the stream have failed which has led to low to moderate bed degradation immediately behind
these structures. Of the twenty-four rock vanes that were installed, sixteen are not performing their
intended function. Three vanes have water piping through or behind the structure, six have filled in with
sediment and have become obsolete, and the remaining seven are flooded from beaver dams throughout
the lower portion of the Site. A total of eight beaver dams were observed within the UT to Bear Swamp
Creek and significant impoundments have formed behind them. One beaver dam, constructed at the
upstream culvert invert, posed a potential flood hazard to the Murphy Hay Farm driveway. In late 2007,
beaver trapping and removal was carried out at the Site to prevent offsite flooding, continued negative
impacts to the stream, and potential nuisance impacts to the adjacent landowners.
Based on the cross-sections and visual observations, the channel dimensions have not changed
significantly. The stream was designed as a 135c (step-pool) stream (Rosgen 1996), which provides a
sand bed channel with moderate entrenchment and a moderate width-depth ratio. During the current
survey, bankfull indicators continue to be found at a significantly lower elevation than those described by
the designer. The current classification measurements also exhibit a very low width-depth ratio and
entrenchment consistent with an E-channel. Pebble counts show no significant change to the channel
substrate which is composed primarily of sand and fine gravel.
EEP Project No. 27 2 UT to Bear Swamp Creek Restoration Site
2.0 PROJECT BACKGROUND
2.1 LOCATION AND SETTING
The Site is located north of Louisburg in Franklin County, NC, immediately south of West Dyking Road
(SR 1235) at the Murphy Hay Farm (Figure 1, Appendix A). From Raleigh follow Highway 401 north to
Louisburg. Approximately one mile past the Highway 561 split in Louisburg take a left onto West
Dyking Road. The Murphy Hay Farm will be approximately one mile on your left. The entrance to the
stream restoration area is accessed by several cattle gates located along an electrified fence. The stream
restoration reach begins approximately 460 feet upstream of the driveway crossing and ends
approximately 775 feet downstream.
2.2 RESTORATION STRUCTURE AND OBJECTIVES
Approximately 1400 linear feet of an Unnamed Tributary (UT) to Bear Swamp Creek were identified on
the 32-acre Murphy Hay Farm. The stream had severely degraded and eroded significantly due to past
vegetation removal and the unrestricted access of cattle. The torrential rain events associated with
Hurricanes Fran and Floyd provided the final impetus for restoration work. The stream originates at a
pond approximately 500 feet east of West Dyking Road and 1000 feet east of the project. Land use in the
watershed consists of agriculture, pasture, forest, and single-family residential.
The design of the new stream included both Priority II and III stream restoration. The degraded F5 and
G5c stream types were restored to a 135c (Rosgen 1996). Approximately 664 linear feet of new channel
was constructed; and 771 linear feet of stream was stabilized in-place. Approximately 800 tons of rock
was used to construct 24 rock vanes throughout the reach (Figure 2-1, 2-2, 2-3, Appendix A). The vanes
were designed to improve hydraulic flow and reduce shear stress. The vanes were to provide bed
stabilization and improved stream habitat by creating pools. The steep, eroded banks were graded back
and expanded to increase the entrenchment ratio. Root wads were also installed to provide bank
protecting and additional habitat diversity. Approximately 2.4 acres of riparian vegetation was also
established along the restored channel in Zone 1 (inner 30 feet) of the Tar/Pamlico Riparian Buffer. This
riparian buffer zone has been fenced to exclude cattle. Site construction began and was completed in July
2002. Project monitoring began the next year in September 2003.
The objective of this project is to restore habitat and water quality to the restored reach and the Tar-
Pamlico River Basin as a whole. By stabilizing the streambed and banks, the restoration will improve
water quality by reducing the amount of sediment contributed to the watershed. Exclusion of cattle and
establishment of a permanent riparian buffer should further help reduce sediment and nutrient input. The
newly established riparian buffer will provide shade, thereby reducing water temperatures, and increase
habitat and food for wildlife.

Vegetation monitoring for Year 5 was performed based on the Carolina Vegetation Survey (CVS) Levels
1 and 2 (Lee et al. 2006). Plot locations are consistent with previous years and plot size remained 5m x
20m. Based on recommendations by EEP, Plot 4 was not surveyed in the current monitoring year. Stem
counts were conducted for all woody species, including volunteer species. The taxonomic standard for
vegetation follows Flora of the Carolinas, Virginia, Georgia, and surrounding areas (Weakley, 2007).
An inventory of planted species is given in Table VIIa, while volunteer species are listed in Table VIIb.

EEP Project No. 27 7 UT to Bear Swamp Creek Restoration Site
A total of 29 stems of planted species were counted in the four plots. Stem density per acre for Plots 1, 2,
3, and 5 are 728, 364, 40, and 40 stems per acre. The average density for planted species in all plots is
293 stems per acre, which exceeds the established success criteria of 260 stems per acre for vegetation at
year 5.
Silky dogwood and elderberry have survived and grown on moister and more exposed sites on the stream
banks, but have largely been out-competed in the drier upland sites where the vegetation plots are located.
Survival of tag alder, winterberry, ironwood, red mulberry, and cherrybark oak appears to have been very
poor. The apparent cause of mortality for these species is competition from fast-growing woody species,
principally loblolly pine, and from large herbs such as Johnson grass (Sorghum halapense), goldenrod
(Solidago sp.), and dog fennel (Eupatorium capillifolium). Drought conditions may have also contributed
to poor survival throughout the Site.

A total of 813 stems of volunteer species were counted in the four plots. Density per acre for Plots 1
through 5 is 21,165, 4,654, 2,185, and 4,897 respectively, with an average of 8,225 volunteer woody
stems per acre. Density for Plots 1 through 5, including planted and volunteer species, is 21,894, 5,018,
2,226, and 4,937 respectively, with an average of 8519 stems per acre.
EEP Project No. 27 8 UT to Bear Swamp Creek Restoration Site
Aggressive recruitment of Pinus taeda continues at the Site, especially at the northeastern end
(Appendix B). A mixed pine-hardwood woodlot near this area provides a nearby source of pine
propagules. The northeastern end of the Site, near Plot 1, also features abundant Rhus shrubs, principally
Rhus glabra. While these are abundant, they do not generate the dense shade found under pine saplings.
The unbranched stems and weak vegetative growth result in an open understory where grasses and herbs
flourish.
An informal inventory of herbaceous species on the site was also taken. Dominant herbaceous species
over the Site as a whole are listed below:
long-stalked aster (Symphyotrichum dumosum) pokeweed (Phytolacca americana)
beggar ticks (Bidens frondosa) smartweed (Persicaria sp.)
Indian strawberry (Potentilla indica) curly dock (Rumex crispus)
purple coneflower (Echinacea purpurea) horse nettle (Solanum carolinense)
bottlebrush grass (Elymus hystrix) goldenrod (Solidago sp.)
dog fennel (Eupatorium capillifolium) Johnson grass (Sorghum halapense)

Includes constructed riffles and pools that are functioning as intended, as well as any others observed in the field.
Based on Rosgen type B stream with every structure having an associated riffle and pool.
Flooding from beaver dams within UT to Bear Swamp Creek prohibited an evaluation of some vanes. Any vanes observed to
be piping or failing during Year 4 Monitoring, but are currently flooded, are still considered failing in Year 5.
