The meeting began with RS summarizing the current conditions at the GUC Site and outlining all AMP work completed between year 1 (2020) through year 4 (2023). MY 4 (2023) vegetation monitoring resulted in a site - wide average of 241 stems per acre. Success for the Site is 260 stems per acre. However, many portions of the Site are below the success criteria. Following the Site summary, a site walk-through was conducted. Based on in -field observations, NCDEQ staff determined that MY 4 results are representative. The Site has numerous areas that are underperforming success criteria. NCDEQ requested that RS submit an AMP for approval. The AMP is intended to serve as a test for potential remedies, particularly the potential for additional planting of alternate species. Details of the Site Visit discussions are outlined below. Meeting Notes: - Site was walked in order of numbered features, beginning at Northeast corner. Higher elevations and sandier soils were observed to be especially problematic areas for tree establishment. - Sycamores stood out visually as a high vigor species despite a low initial planting density. Many species noted as present showed low heights and low vigor, with obvious signs of heavy deer browse and apparently challenging fertility/moisture conditions. - Persimmons appeared to be the most prevalent volunteer species on the Site. - Beavers are established in Features 5, 6, and 7 and seem to be benefitting the site. - The vegetation on the Sand ridge located south of Feature 7 (Figure 1).was significantly lower than the rest of the Site. 0 NCDEQ staff requested RS to compare species mortality between as -built My 0 (2020) data and MY 4 (2023) results. RS will use the data to develop a species list within the highlighted area for the AMP. Development of AMP (2024) discussion. o NCDEQ staff agreed to postpone MY 5 (2024) monitoring (sitewide monitoring to resume in 2026) to allow the development and implementation of an AMP. o Continue annual monitoring of overall easement conditions, including boundary encroachments, wild hog disturbance, drought/flooding, etc. o Plant multiple test zones to consider alternative tree species and better understand causes of tree mortality to date. ■ Ten to twelve (10-12) zones should be spread out to include representative areas including all features, soils, and relative landscape positions. ■ Submit soil samples from each zone and provide representative soil profiles. o DWR suggested including species currently on -site observed with high vigor, including Sycamore (Platanus occidentalis) and Persimmon (Diospyros virginiana). o DWR also requested the addition of Loblolly Pine (Pinus taeda) and Red maple (Acerrubrum), as species typically tolerant of very difficult site conditions. o DWR suggested a shrub species. Considering site conditions, RS staff believes Wax myrtle (Myrica cerifera) to be the most suitable shrub species widely available. o Material used will be at RS's discretion (Le., container or bare root) o Monitoring within the AMP (2024) test zones. ■ Monitoring guidelines • Added stems will be flagged. • Mortality, height, and vigor for added stems will be monitored. o Anticipated AMP (2024) schedule (Table 1). Dates Milestones Summer 2024 AMP submittal for NCDEQ review January 2025 Implementation of NCDEQ- approved AMP February 2025 AMP as -built MY 0 monitoring Fall 2025 AMP MY 1 Monitoring AMP MY 2 Monitoring and Fall 2026 continue site -wide MY 5 monitoring Potential site -wide supplemental January 2027 planting based on results of AMP test plots o Determination of close-out/ potential credit reduction. ■ Based on the AMP, an effective two-year monitoring delay is in place for this site. ■ Close-out will be considered in 2027. The completion of monitoring requirements and the research AMP (2024) are required. Implementation of a Site wide supplemental planting based on results of the AMP (2024) may support close-out efforts. Areas which do not meet success criteria and are unlikely to do so may be subject to credit reductions at close-out. iti>�I T Feet 0 212.5 425 850 1,275 1,700 fly: Legend OGUC Easement = 97.14 acres As -Built CVS Plots '~ . „ Sand Ridge/Low Veg.
