The Site is located approximately 0.25 mile south of Smithfield, in Johnston County. This portion of Johnston County is located centrally within Neuse River Basin 14-digit Targeted Local Watershed 03020201140010. The Site encompasses approximately 15 acres immediately adjacent to unnamed tributaries to the Neuse River. A total of 15 Buffer Mitigation Units, resulting from 15 acres of buffer restoration, were completed in January 2006. Prior to restoration, Site land use consisted of agricultural fields utilized for row crop production. Site stream banks were characterized by little or no vegetation and extensive erosion. Excessive runoff during storms from nearby Interstate 95 appeared to have exacerbated stream bank erosion problems caused by previous onsite land use. Site reforestation, consisting of a Mesic Pine Flatwoods community, was implemented within the entire 15-acre Site. The primary goals of this buffer restoration project focused on reforestation of the Site with native species to 1) improve water quality; 2) enhance flood attenuation; 3) reduce sedimentation/siltation; 4) increase channel bank stability; 5) filter and reduce pollutants prior to entering the Neuse River; 6) serve as a wildlife corridor by providing connectivity to forested areas adjacent to the Site; 7) provide increased habitat for aquatic and terrestrial wildlife; 8) increase organic matter, carbon export, and woody debris in the stream corridor; 9) restore shade to open waters; 10) increase potential for freshwater mussel recruitment; 11) enhance macroinvertebrate species populations in the channel; 12) augment the existing Mesic Pine Flatwoods Natural Community documented by the North Carolina Natural Heritage Program (NCNHP) just northeast of the Site; and 13) expand potential red-cockaded woodpecker (Picoides borealis) foraging habitat for populations documented by the North Carolina Natural Heritage Program (NCNHP) approximately 0.3 mile and 0.9 mile northeast of the Site. As a whole, the densities of four vegetation plots across the Site were above the required 320 stems/acre with an average of 1,032 tree stems per acre in the Second Monitoring Year (Year 2007). All individual vegetation plots met success criteria and had good species diversity with 6 to 11 Character Tree Species present within each plot. Average stems per acre nearly doubled across the Site compared to 2006 monitoring data; however, species diversity decreased slightly.

The Site is located approximately 0.25 mile south of Smithfield, in Johnston County (Figure 1). The Site conservation easement encompasses 15 acres immediately adjacent to unnamed tributaries to the Neuse River within subbasin 03-04-02 of the Neuse River Basin. The Site is part of United States Geological Survey Catalog Unit 03020201 of the South Atlantic/Gulf Region and is encompassed within a watershed that has been targeted for restoration needs (Targeted Local Watershed 03020201140010) (NCWRP 2002). A Detailed Buffer Restoration Plan was completed for the Site in July 2005. The plan outlined methods designed to reforest the entire 15-acre Site with native species. Prior to implementation, the entire Site was composed of row-crop agriculture. The following implemented activities provide 15 Buffer Mitigation Units as requested under the EEP Request for Proposal (RFP) 16- D05015 dated October 22, 2004: • Restoration of approximately 15 acres of riparian buffer through planting with native forest species. • Protection of the Site in perpetuity with a conservation easement which is held by the State of North Carolina. The primary goals of this buffer restoration project focused on reforestation of the entire 15-acre Site with native species to 1) improve water quality; 2) enhance flood attenuation; 3) reduce sedimentation/siltation; 4) increase channel bank stability; 5) filter and reduce pollutants prior to entering the Neuse River; 6) serve as a wildlife corridor by providing connectivity to forested areas adjacent to the Site; 7) provide increased habitat for aquatic and terrestrial wildlife; 8) increase organic matter, carbon export, and woody debris in the stream corridor; 9) restore shade to Site open waters; 10) increase potential for appropriate mussel habitat; 11) enhance characteristic macroinvertebrate species populations in the channel; 12) augment the existing Mesic Pine Flatwoods Natural Community documented by the North Carolina Natural Heritage Program (NCNHP) just northeast of the Site; and 13) expand potential red-cockaded woodpecker (Picoides borealis) foraging habitat for populations documented by the NCNHP approximately 0.3 mile and 0.9 mile northeast of the Site.

Removing non-point sources of pollution associated with agricultural production including a) cessation of broadcasting fertilizer, pesticides, and other agricultural materials into and adjacent to Site streams and b) providing a vegetative buffer adjacent to streams to treat surface runoff. 2. Reducing sedimentation in onsite and downstream receiving waters through a) reduction of bank erosion associated with agricultural practices, b) filter surface runoff from adjacent land and reduce particulate matter deposited into area waterways, and c) planting a forested buffer adjacent to Site streams. 3. Promoting floodwater attenuation by revegetating Site floodplains thereby promoting increased frictional resistance on floodwaters crossing Site floodplains. 4. Providing wildlife habitat including a forested riparian corridor. As constructed, the Site provides 15 acres of riparian buffer restoration (15 Buffer Mitigation Units). On July 1, 2005, EEP contracted with Restoration Systems to complete restoration of the Site. A Detailed Buffer Restoration Plan was completed for the project in July 2005. Upon completion of the detailed plan, Bruton Nurseries and Landscapes planted the Site during the first week of January 2006. Axiom Environmental, Inc. completed an As-built Mitigation Report in April 2006. Information on project managers, owners, and contractors follows: Owner Information Restoration Systems, L.L.C.

A general discussion of the plant community restoration monitoring program is provided. Monitoring of restoration efforts will be performed for a minimum of 5 years or until success criteria are fulfilled. The locations of monitoring plots are depicted in Figure 2. Quantitative second year sampling was conducted on August 10, 2007. Future quantitative vegetation sampling will be performed between June 1 and September 30 of each monitoring year for five years or until the vegetation success criteria are achieved. Four sample transects were installed within planted areas of the Site shortly after replanting to equally represent the Site (Figure 2). Each transect is 300 feet in length and 8 feet in width (0.055 acre). In each sample plot, vegetation parameters monitored include species composition and species density. Visual observations of the percent cover of shrub and herbaceous species were also noted. Photographs of the 4 vegetation plots are included in Appendix A. 2.1 Vegetation Success Criteria Success criteria have been established to verify that the vegetation component is dependent upon density and growth of "Character Tree Species." Character Tree Species include planted species, those observed in forest stands near the Site, and those listed in the Mesic Pine Flatwood community descriptions from Classification of the Natural Communities of North Carolina (Schafale and Weakley 1990). All planted canopy tree species and those identified in Schafale and Weakley (1990) will be utilized to define "Character Tree Species" as termed in the success criteria. Table 1.

Additional seedlings are expected to be recruited to the Site from adjacent forested communities. These individuals may also be counted in the overall success rate for the Site provided they are native hardwood tree species. If vegetation success criteria are not achieved based on average density calculations from combined plots over the entire restoration area, supplemental planting may be performed with Character Tree Species. Supplemental planting will be performed as needed until achievement of vegetation success criteria. No quantitative sampling requirements are proposed for herb assemblages as part of the vegetation success criteria. Development of floodplain forests over several decades will dictate the success in recruitment and establishment of desired understory and groundcover populations. Visual estimates of the percent cover of herbaceous species will be noted and documented through periodic photographs. Photographs of the vegetation plots are included in Appendix A. 2.2 Vegetation Sampling Results and Comparison to Success Criteria Quantitative sampling of vegetation was conducted on August 10, 2007. Results are provided in Table 2. Vegetation success criteria for year 2 (320 stems per acre) were exceeded for the 2007 annual monitoring year with 1,032 tree stems per acre across the Site. All individual vegetation plots met success criteria and had good species diversity with 6 to 11 Character Tree Species present within each plot. 3.0 CONCLUSIONS In summary, as a whole, vegetation plots across the Site were above the required 320 stems/acre with an average of 1,032 tree stems per acre in the Second Monitoring Year (Year 2007). All individual vegetation plots met success criteria and had good species diversity with 6 to 11 Character Tree Species present within each plot. The average number of stems per acre nearly doubled across the Site compared to 2006 monitoring data, however, species diversity decreased slightly. Documented animal species that utilize the developing wetland ecosystem are listed in Appendix B.
