The Parcel surrounds tributaries to South Fork Cane Creek in Chatham County, NC (Figure 1). The purpose of the Parcel is to provide riparian buffer and nutrient offset mitigation credits to compensate for unavoidable buffer impacts in the 03030002 Hydrologic Unit Code (HUC) of the Cape Fear River Basin, within the Haw River Sub -watershed of the Jordan Lake Watershed. The Parcel was planned and designed according to the Consolidated Buffer Mitigation Rule 15A NCAC 02B .0295 (effective November 1, 2015) and 15A NCAC 02B .0703. The service area is depicted in Figure 2. 1.0 Introduction This Parcel was developed to provide stream mitigation through the creation of a Stream Mitigation Bank as well as nutrient offset and buffer mitigation through the creation of a Nutrient Offset & Buffer Mitigation Bank. Riparian restoration activities deemed suitable for nutrient offset on this Parcel will generate 2,249.36 lbs. -Nitrogen per acre and 143.81 lbs. -Phosphorus per acre (with a delivery factor of 71% and 67% respectively). The Parcel involved restoring riparian buffers adjacent to mitigated streams onsite to help reduce non - point source contaminant discharges to downstream waters in the Jordan Lake Watershed within the Cape Fear River Basin. Approximately 18.13 acres are protected with a permanent conservation easement. Of the 18.13 acres, 14.83 acres have been restored for either Jordan Lake riparian buffer credit or nutrient offset credit. In general, riparian buffer restoration area widths on streams range from 50 feet to 100 feet from the top of bank. 2.0 Parcel Location & Background 2.1 Project history Project history can be found below in Table 1.

The cattle pastures on the Parcel were dominated by fescue grasses (Festuca spp.) and broomsedge (Andropogon virginicus). Much of the riparian area on the Parcel was wooded; however, cattle had access to the streams. Vegetation in the wooded areas is primarily hardwood species including white oak (Quercus alba), red oak (Quercus rubra), willow oak (Quercus phellos), tulip poplar (Liriodendron tulipifera), sweetgum (Liquidambarstyraciflua), red maple (Acerrubrum), southern red oak (Quercus falcata), and American elm (Ulmus americana) (Table 2).

The riparian buffer will immobilize nutrients, reducing quantities available to downstream aquatic ecosystems in the Cape Fear River Basin. Table 3.

The specific species composition that was planted was selected based on the community type, observation of occurrence of species in riparian buffers adjacent to the Parcel, and best professional judgement on species establishment and anticipated Parcel conditions in the early years following project implementation (Table 3). Trees were planted at a density sufficient to meet the performance standards outlined in the Consolidated Buffer Mitigation Rule 15A NCAC 02B .0295 of 260 trees per acre at the end of five years. An appropriate seed mix was also applied to provide ground cover for soil stabilization and reduction of sediment loss, as necessary. While planting was not anticipated to be needed in the cattle exclusion areas, except where required in the stream mitigation plan, a seed mix was applied where cattle had removed all vegetation and caused bare soils. The cattle exclusion areas within the easement were fenced to prevent further cattle encroachment by using Three -Strand High Tensile Wire Fence, which was later changed to woven barbed wire fencing in January 2021. No planting was performed in the buffer preservation areas except in areas affected during construction. Table 4.

The number of plots required was determined in accordance with the Carolina Vegetative Sampling Protocol (CVS) Levels 1 & 2. Performance Standards for the Parcel are based on the health and survival of a minimum density of 260 trees per acre after five years of monitoring, and no one species comprises more than 50 percent of stems. Height, visual assessment of damage, and vigor are used as indicators of overall health. Desirable volunteer species may be included to meet the success criteria upon NCDWR approval. A reference W South Fork Nutrient Offset and Buffer Mitigation Bank Parcel Page 4 Monitoring Year 5 Report photo was taken from the southwestern corner of each vegetation plot and included in the appendix. All planted stems in the vegetation plots were marked with flagging tape and recorded. The total number of each tree species planted within the monitoring plots, as well as planting density, and composition at as -built are included in Table 4 for comparison purposes. Annual monitoring activities began in the fall of 2019 and will continue each year for the remainder of the monitoring period. Species composition, density, and survival rates will be evaluated on an annual basis by plot for the entire Parcel. An annual monitoring report will be submitted to NCDWR no later than December 315Y of each year for five consecutive years. 3.2 Results of Vegetation and Visual Assessment Monitoring The 5 vegetation plots (Plots 3-7) were sampled in September 2023 at the end of the fifth growing season. A reference photo was taken from the southwest corner of each plot, which can be found in Appendix D along with the stem count raw data. Total numbers of planted tree species identified within the monitoring plots as well as density and composition are summarized in Table 5. Vegetation result tables with planted stem density, and stem count by plot and species are summarized in Appendix C. The 2023 vegetation monitoring resulted in an average planted stem density of 445 stems per acre with individual plot densities ranging from 364 to 526 stems per acre. When including volunteer species, the average stem density is 1,238 stems per acre with individual plot densities ranging from 647 to 1,700 stems per acre. Both planted and total average stem densities well exceed the final requirement of 260 stems per acre. All plots have 4 or more planted species and most stems across plots have scored high in vigor. Additionally, plots have shown a positive trend in average height throughout monitoring years (see Appendix Q. Vegetation plots 4, 6, and 7 have relatively dense volunteer populations. Plot 7 has 18 green ash volunteers, while plots 4 and 6 have 21 and 18 sweet gum volunteers, respectively. These volunteers do not appear to be adversely impacting planted stems. Furthermore, most planted stems within these plots scored high on vigor, indicating that they are healthy. Volunteer species will continue to be monitored to ensure they do not out -compete planted species. If volunteer species hinder the growth of planted trees remedial actions will be taken. Visual assessments of the cattle exclusion and preservation areas within the conservation easement concluded: • Fencing is in good condition throughout the Parcel; • No cattle access within the conservation easement area; • No encroachment has occurred; • Diffuse flow is being maintained in the conservation easement area; and • There has not been any cutting, clearing, filling, grading, or similar activities that would negatively affect the functioning of the buffer. The Parcel is on track to meet its final success criteria. Table 5.

The high tinsel fencing was therefore replaced with woven barbed wire during January 2021. Cows have continued to occasionally bypass the fencing at crossings, where the original high tinsel fencing remains; however, the landowner has been contacted and no permanent damage as a result of cattle encroachment has been observed. While vegetation plot data has reflected that trees are doing well across the Parcel, closer visual assessments at the end of monitoring year 4 and beginning of monitoring year 5 led Wildlands to believe that some areas not represented by vegetation plots would benefit from a relatively low -density supplemental planting. Therefore, 0.93 acres were supplementally planted in late February 2023 at a density of 100 stems per acre along UT1 and UT2. Wildlands notified NCDWR of the intent to perform a supplemental planting via email on February 2"d, 2023. A combination of bare root and 1-gallon containerized stems were used. Species selected were originally approved in the Bank Parcel Development Package (BPDP). Prior to the supplemental planting, these areas were brush cut to minimize blackberry shrub competition. To further ensure the success of the supplemental planting, soil amendments were applied locally around the base of each tree in April 2023. Localized soil amendments were performed along UT2 and SF4A. Following their first growing season, most of the new stems have survived and appear healthy. In prior monitoring years, infrequently dispersed princess tree (Paulownia tomentosa), tree of heaven (Ailanthus altissima), and Chinese privet (Ligustrum sinense) stems had been observed and treated. In June and July 2023 these species were again treated as scattered stems appeared throughout the Parcel. Additionally, sweetgum stems were selectively thinned along a portion of the right bank of SMA close to the downstream crossing where they posed a threat of hindering the growth of more desirable species. Throughout the remainder of the Parcel, adaptive measures will be developed, or appropriate remedial actions will be implemented in the event the Parcel, or a specific component of the Parcel fails to achieve the success criteria. Parcel maintenance will be performed to correct any identified problems that have a high likelihood of affecting project success. Such items include but are not limited to excess tree mortality caused by fire, flooding, drought, or insects. Any actions implemented will be designed to achieve the success criteria and will include a work schedule and updated monitoring criteria. 5.0 Conclusions Overall, vegetation is doing well across the Parcel, with most recorded stems scoring high in vigor and the vegetation plots continuing to display a positive change in height. The Parcel has an average planted stem density of 445 stems per acre with individual plot densities ranging from 364 to 526 stems per acre. When including volunteer species, the average stem density increases to 1,238 stems per acre, with plots ranging from 647 to 1,700 stems per acre. Based on visual assessment, the February 2023 W South Fork Nutrient Offset and Buffer Mitigation Bank Parcel Page 6 Monitoring Year 5 Report supplementally planted stems have shown a high rate of survival throughout their first growing season. Scattered occurrences of tree of heaven, princess tree, and Chinese privet were noted across the Parcel and treated in June and July of 2023. Sweet gum stems were also selectively thinned along a portion of SF4A to reduce their competition with planted species. Native and non-native invasive plant populations have remained under control throughout monitoring year 5 and do not appear to pose a threat to desirable vegetation. 6.0 References Guidelines for Riparian Buffer Restoration.
