(Wildlands) implemented a full delivery project at the Sassarixa Swamp Mitigation Site (Site) for the North Carolina Department of Environmental Quality(NCDEQ) Division of Mitigation Services (DMS).A conservation easement comprised of 65.06 acres along Sassarixa Creek and seven unnamed tributaries to Sassarixa Creek, along with six unnamed tributaries to Black Creek in the Neuse River Basin are included in the project. A total of 55.26 acres (2,407,138 ft2) of riparian buffer have been restored, enhanced, or preserved and are expected to generate 1,080,282.590 riparian buffer credits,with potential to convert some buffer credits to nutrient offset credits dependent on the need. The Site is located approximately six miles southwest of Smithfield and five miles north of Four Oaks (Figure 1). Project information and attributes are described in Table 4 located in Appendix 1.The Site drains to Holts Lake,which is a recreational lake classified as Nutrient Sensitive Waters (NSW). Holts Lake then drains to the Neuse River, which is a water supply for the City of Goldsboro. Work at the Site was planned, designed, and constructed per the Sassarixa Swamp Mitigation Site— Riparian Buffer Mitigation Plan (Wildlands, 2020) and the Consolidated Buffer Mitigation Rule 15A NCAC 02B .0295 (effective November 1, 2015). The purpose of the riparian buffer restoration is to provide riparian buffer credits to compensate for buffer impacts within the Hydrologic Unit Code 03020201.The service area for the riparian buffer credits is depicted in Figure 2.The mitigation credits generated from the Site are included in Table 1 and illustrated in Figure 3 located in Appendix 1. J..2 Project Goals and Objectives The project includes several adjacent properties that have been owned and operated as a livestock farm by a single family since 1850, where livestock are continually rotated through all fields (with access to their associated streams).The western portion of the project includes Sassarixa Creek and seven unnamed tributaries to Sassarixa Creek(T1,T1A,T1B,T1C,T1D,T2, and T3) (Figure 2).The eastern portion of the site contains six unnamed tributaries to Black Creek(T4,T5,TSA,TSB,TSC, and T6). A review of historic aerials from 1950 to 2012, showed that onsite streams have existed in their approximate locations with very little change to riparian zones since 1950.Two alterations to the Site visible from aerial photography are the addition of the pond on T2 between 1964 and 1973, and the addition of the large pond below TSA,TSB, and TSC, between 1950 and 1961. The Site is located in a new Targeted Local Watershed (TLW)that is not described in the 2010 Neuse River Basin Restoration Priorities (RBRP) Plan.The TLW was added in the 2015 Neuse 01 Cataloging Unit (CU) Update because there were more water quality issues than assets.The Site addresses the TLW stressors of agricultural land use/animal operations and the lack of protected riparian areas.The project will also address key CU wide restoration goals for the Neuse River 03020201 described in the RBRP (NC DWR 2009). Specific enhancements to water quality and ecological processes are outlined below: • Decrease nutrient levels- Nutrient input will be decreased by filtering runoff from the agricultural fields through restored native buffer zones.The off-site nutrient input will also be absorbed on-site by dispersing flood flows through native vegetation, thereby reducing nutrient inputs to waters of the Neuse River Basin. • Exclude cattle from project streams. - Install fencing around project areas adjacent to cattle pastures. • Decrease water temperature and increase dissolved oxygen concentrations- Establishment and maintenance of riparian buffers will create additional long-term shading of the channel flow to reduce thermal pollution. key Sassarixa Swamp Mitigation Site Monitoring Year 1 Annual Buffer Report-Final 1 • Restore and enhance native floodplain vegetation - Plant native tree species in riparian zone where currently insufficient. • Permanently protect the Site from harmful uses- Establish a conservation easement on the Site. Protect aquatic habitat; protecting water supply waters. The 65.06-acre Site is protected with a permanent conservation easement. Of the 65.06 acres, Neuse riparian buffer credits were generated by restoring 10.03 acres, enhancing 34.41 acres, and preserving 10.82. No buffer credit will be generated from the remaining 9.80 acres. In general, riparian buffer restoration area widths on streams extend out to 50 feet from top of bank on each side of the stream channel. Figure 3 and Table 1 in Appendix 1 detail the buffer credit generation. 1.3 Monitoring Year 1 Data Assessment The Mitigation Plan (Wildlands, 2019)was submitted and accepted by DMS in November 2019. Construction activities by Land Mechanic Designs, Inc. was completed in January 2021, while tree planting by Bruton Natural Systems, Inc. was completed in March 2021.The baseline as-built survey was completed by Kee Mapping and Surveying in February 2021. Refer to Appendix 1 for detailed project activity, history, contact information, and watershed/site background information. Vegetative performance for buffer restoration areas will be in accordance with 15A NCAC 02B .0295(n)(2)(B), and (n)(4) (effective November 1, 2015).To meet success criteria, areas generating buffer mitigation credits shall include a minimum of four native hardwood tree species,where no one species is greater than 50 percent of stems, and shall have a survival of at least 260 planted stems per acre at the end of the required five-year monitoring period. For monitoring to be completed and buffer credit to be awarded, NCDWR must provide written approval of successful revegetation of buffer restoration areas. Year 1 monitoring (MY1)was conducted to assess the condition of the vegetation in September 2021. 1.3.1 Vegetative Assessment The quantity of monitoring vegetation plots was determined in accordance with the Wilmington District Stream and Wetland Compensatory Mitigation Update (NCIRT, 2016) such that at least 2 percent of the Site is encompassed in monitoring plots. A total of 10 vegetation plots (each 100 square meters)were established within the conservation easement boundaries.The plot corners have been marked and are recoverable either through field identification or with the use of a GPS unit. Reference photographs are taken at the origin looking diagonally across the plot to the opposite corner on an annual basis.Trees will be marked annually with flagging tape. Species composition, vigor, height, density, and survival rates will be evaluated by plot on an annual basis.The extent of invasive species coverage will also be monitored and controlled as necessary. The MY1 vegetation monitoring was completed in September 2021, resulting in an average survival of 506 planted stems per acre.The Site is exceeding the final requirement of 260 stems per acre, with 9 of the 10 plots individually exceeding this requirement.The planted stem mortality was approximately 11% of the baseline stem count(566 stems per acre) in March 2021.There is an average of 12 stems per plot. Vegetation plot 2 is not on track to meet the final success requirement with 243 stems per acre. A more thorough visual assessment will take place in the area near vegetation plot 2 in Spring 2022 to assess the survivability of the planted trees and resprouts. Refer to Appendix 2 for the vegetation condition assessment table, monitoring plan view maps, vegetation plot and overview photographs. Appendix 3 contains vegetation plot data and vegetation plot performance summary table. key Sassarixa Swamp Mitigation Site Monitoring Year 1 Annual Buffer Report-Final 2 1.3.2 Vegetation Areas of Concern Before construction, Chinese privet (Ligustrum sinense) was treated along Sasssarixa Creek during the winter of 2020/2021 using a combination of methods including foliar and cut stump applications. Out of the 27.00 acres that was originally treated, resprouts did emerge along the lower half of Sassarixa Creek totaling 11.99 acres (Figure la). A follow up treatment will occur during MY2 to treat the resprouts. Several cattle were observed within the Site throughout July 2021. Cattle had access to 11.39 acres of the Site between the Sassarixa Creek ford crossing to the top of T1 (Figure la). The cattle were entering the Site through the high tensile fence along the Sassarixa Creek ford crossing.The landowner has agreed to keep the outside gates closed unless supervising the cattle crossing Sassarixa Creek. No cattle have been seen in the easement since July 2021, indicating the easement encroachment has been resolved. No major damage occurred to the Site due to cattle encroachment, except for several dented easement signs 1.4 Monitoring Year 1 Summary Overall,the Site has exceeded the required vegetation success criteria for MY1. Vegetation plot 2 is not on track to meet the final success criteria. A visual assessment will take place in Spring 2022 to assess survivability and resprouts.The rest of the Site's vegetation layer established quickly and is greatly reducing the amount of nutrients and sediment from entering the project streams. A follow up treatment of the Chinese privet resprouts along Sassarixa Creek will occur during MY2. Cattle were accessing the easement through the Sassarixa Creek ford crossing, but since communicating with the landowner, no cattle have been observed in the easement since July 2021. Summary information/data related to the performance of various project and monitoring elements can be found in the tables and figures in the report appendices. Narrative background and supporting information,formerly found in these reports, can be found in the Mitigation Plan (Wildlands, 2020) available on DMS's website. All raw data supporting the tables and figures in the appendices are available from DMS upon request. Section 2: METHODOLOGY Planted woody vegetation was monitored in accordance with the guidelines and procedures developed by the Wilmington District Stream and Wetland Compensatory Mitigation Update (NCIRT, 2016). A total of ten fixed 100 square meter vegetation monitoring quadrants were established within the Site conservation easement area. key Sassarixa Swamp Mitigation Site Monitoring Year 1 Annual Buffer Report-Final 3 Section 3: REFERENCES Breeding, R. 2010.
