The project is in northwest Robeson County, approximately 6 miles north of Maxton, off Modest Rd (Figure 1). This project includes rehabilitation of non-riparian wetlands and preservation of existing forested and ponded wetlands(Table 1). The Project site is a former agricultural field, located on an inter-stream divide between the Lumber River and Black Gum Swamp, surrounded by forested areas and agricultural parcels. The site was altered since the mid-80s,which included ditching and clearing. The site contains approximately 9.940 acres exhibiting wetland hydrology and soils (Wetland 1), but initially was lacking in hydrophytic vegetation, lending itself to a rehabilitation restoration approach using the definitions provided in 40 CFR Part 230 (Final Rule). Additionally,there are two jurisdictional wetland communities on the site, as confirmed by an approved jurisdictional determination (JD) by the US Army Corps of Engineers on January 6, 2016, leading to a preservation approach to provide wetland restoration equivalents(RE). These preservation areas include 23.042 acres of a successional wetland and forested hardwood flat in the Southern section of the project (Wetland 2)and 51.382 acres of forested hardwood flat/pocosin and open water/wetland habitat in the northern section of the project, for a total of 74.424 acres of preservation (Figure 2). These acreages have been updated from the Mitigation Plan to As-Built stage due to GIS geometry calculation. Wetland restoration activities included planting the rehabilitation areas in March 2016 with 5,010 bare root species from the Hardwood Flat Forest Community(NCWAM, v.4.1 2010)as well as other similar species found in the adjacent forested wetland community. There were six(6)different species selected to reflect the target vegetative community. 1.1 Goals and Objectives The Lumber River Basin Restoration Priorities state that the goals for the Black Gum Creek 14-digit HUC are: • Replacing buffer • Repairing channelized streams • Preservation of existing resources. The following specific project goals, as stated in the Mitigation Plan, include: • Restoring a hardwood flat vegetation community • Expanding forested wetland complex The success of these project goals will be addressed through the following objectives: • Plant native tree/shrub species • Preserve existing hardwood flat/pocosin wetlands 2.0 PERFORMANCE STANDARDS 2.1 Vegetation An average density of 260 stems/acre must be surviving after five years of monitoring. Upon completion of planting in March 2016, eight(8) permanent vegetation plots were installed and initial plant stocking was performed to determine species composition and density(Appendix C, Table 6). Vegetation was monitored using the Carolina Vegetation Survey(CVS) protocols level 2 monitoring. Year 5 Annual Monitoring Report Black Gum Creek 97063 4 2.2 Hydrology The site will present continuous saturated or inundated hydrologic conditions for at least 8%of the growing season during normal weather conditions. A"normal"year is based on NRCS climatological data for Robeson County, using the 30th to 70th percentile thresholds as the range of normal.The growing season for Robeson County, using the 50% chance of higher than 28 F method, is from March 22th through November 5th, 228 days(WETS Table, Robeson County). Hydrologic performance is determined through evaluation of automatic recording gauge data supplemented by documentation of wetland hydrology indicators as defined in the 1987 USACE Delineation Manual, daily data will be collected from automatic wells over the 5-year monitoring period. Five(5)continuous monitoring groundwater gauges were installed to provide pre-restoration conditions, and data was downloaded to provide one more year of pre-restoration data for this as-built report. Data from the growing season is provided in Appendix D, along with all monitoring year summary tables. 3.0 MONITORING PLAN Annual monitoring data was reported using the DMS monitoring template. The monitoring report provides a project data chronology to facilitate an understanding of project status and trends, population of DMS databases for analysis, research purposes, and assist in decision making regarding project close-out.

The survivability of the vegetation plantings were evaluated using a 100m2 vegetative sampling plots randomly placed in the planted areas. Groundwater elevation was monitored to evaluate jurisdictional wetland hydrology. Wetland hydrology monitoring occurred with automatic recording of groundwater gauge data collected within the project area. 4.0 MAINTENANCE AND CONTINGENCY PLAN DMS monitored the site and conducted a physical inspection of the site a minimum of once per year throughout the post-construction monitoring period until performance standards were met. These site inspections identified site components and features that may require routine maintenance. Routine maintenance should be expected most often in the first two years following site construction and may include the following: Year 5 Annual Monitoring Report Black Gum Creek 97063 5 Component/Feature Maintenance through project close-out Remedial Measures Vegetation shall be maintained to ensure survival. Routine vegetation Any remedial activities performed will be Vegetation maintenance and repair activities may include supplemental planting. documented in the annual monitoring reports. The site will also be evaluated to ensure diffuse flow is still occurring. Site boundaries shall be identified in the field to ensure clear distinction between the mitigation site and adjacent properties. Boundaries may Site Boundary be identified by fence,marker,bollard,post,tree-blazing,or other Any remedial activities performed will be means as allowed by site conditions and/or conservation easement. documented in the annual monitoring reports. Boundary markers disturbed,damaged,or destroyed will be repaired and/or replaced on an as needed basis. 5.0 YEAR 5 MONITORING Year 5 annual monitoring was conducted on 8/6/2020(vegetation plots)and 1/13/2021 (final gauge downloads).Year 5 monitoring activities included visual monitoring and stem counts of the project vegetation; downloading monitoring gauge data; verifying the presence, or lack of, invasive species; checking the integrity of the easement; and taking photographs at the established photo points. There were 5 gauges on this site, and a 6th gauge was installed 4/30/2019 (nearby gauge 4)for additional hydrologic data. This gauge was destroyed by a bear in 2019 but reinstalled for 2020. Rainfall conditions near this site had low (below 30th percentile)antecedent rain through May. Rainfall during the middle of the growing season was exceptionally high, and then declined significantly again after July. Despite low antecedent conditions, all gauges met the hydrologic success target of greater than 8%of the growing season besides gauge one,which malfunctioned (Appendix D). Gauges 2 and 3 are both located outside of the wetland rehabilitation areas. Gauge 2,which is just outside the rehabilitation asset line, indicated that the water table was continuously above 12"for 24.5%of the growing season and gauge 3,further away from any proposed wetland rehabilitation, had 19.7%continuous hydrology. This information may indicate that the site's hydrologic footprint is expanding more than anticipated for the project and this trend is apparent in the gauge data which has improved steadily throughout the project. Additional DMS monitoring staff observations have shown increased hydrology sitewide over the 7 years of monitoring, likely due to agricultural abandonment, clogged culvert, and overall site high water tables due to elevation and climate. All the vegetation plots met the vegetative success criteria with a project-wide average of 430 stems per acre planted and 981 stems per acre including volunteers. Only one vegetation plot fell below the threshold for success in the planted stems category(VP8), due to the encroachment described below. Although there was no height requirement for success, 6 of the 8 plots were well over the threshold of 7' height, indicating high vigor rates. Plot 6 and plot 8 have a large in-plot height range(Appendix C). There was trespass in the easement and along the credit line where someone bush hogged path that destroyed gauge 1 and mowed a shooting field outside the credit area to the east of gauge 2 in 2019. That path was planted with 100 silky dogwood 2/27/2020; and the impacted area was measured at 1,100 sf. There was additional encroachment noted near VP8 noted in 2020 which included a baiting plot mowed through vegetation plot 8; the area measured approximately 700 square feet. DMS Property staff and Stewardship have been meeting and working with Year 5 Annual Monitoring Report Black Gum Creek 97063 6 the absentee landowner over the last year to determine a solution to the trespasser issue. A gate was installed, and a certified letter went out from the AG office. DMS and Stewardship will continue work towards reconciling the trespass because it is a remote site with an absentee landowner.
