Describe what date the supplemental planting occurred in the monitoring report text and in Table 2. There were no low vigor areas called out in the MY1, although VP 1 and 4 did not meet in MY1. Explain why those vegetation plots were not replanted in the 2020 low-vigor replant that occurred adjacent to them and if and how RS plans to do any additional replanting. Vegetation plots 1 and 4 were not replanted based on Y1 veg success data (including random transects adjacent to the plots). The transect data was collected in the fall of 2019. Based on field assessment in winter of 2020, we felt that although the random transect showed high density of trees, visually(not Y1 plot data) we felt a light planting of additional stems was warranted to help with long term success of these areas. We planted 370 stems of 8 varieties over 1.20 acres(^'300 stems/acre)in the Supplemental Planting Areas shown on the 2020 CCPV. We plan on doing another random transect in these areas to include in the Y3 report. No supplemental planting will occur in 2021. Riparian Buffer Section 1. Section 4.3,Table 5,Table 6, and Figure A state that 2 vegetation plots did not meet success. Riparian buffer success is based on 260 stems/acre planted AND volunteer at MY5. Please revise these report items to reflect this. The riparian buffer section was revised to indicate that all vegetation plots are meeting the success criteria of 260 stems/acre. 2. Add discussion of replanted area to Riparian Buffer report and to Figure A. A discussion of the replanted area was added to section 4.3 of the Riparian Buffer report, and the polygons were added to Figure A. Digital Review- 1. Please submit buffer asset features that are organized by distance (e.g. 0-100, 101-200) and restoration approach.The current features in DMS's possession are not segmented by restoration approach. Please also ensure that these features have areas that match areas reported in Table 2. The riparian buffer asset feature(RiparianBufferAssetsREV.shp)has been included with the final digital submittal. The feature areas match the areas reported in Table 2.

The Site is located within Targeted Local Watershed (TLW) 03030002050050. The RBRP report documents benthic ratings vary between "Fair" and "Good-Fair"possibly due to cattle,dairy, and poultry operations. The project is not located in a Regional or Local Watershed Planning Area; however, RBRP goals are addressed by project activities as follows with Site specific information following the RBRP goals in parenthesis. 1. Reduce and control sediment inputs(reduction of 10.0 tons/year after mitigation is complete); 2. Reduce and manage nutrient inputs (livestock removal from streams, elimination of fertilizer application,and marsh treatment areas may result in a direct reduction of 852.4 pounds of nitrogen and 70.6 pounds of phosphorus per year); 3. Protect and augment designated natural heritage areas. Site specific mitigation goals and objectives were developed through the use of North Carolina Stream Assessment Method(NC SAM)and North Carolina Wetland Assessment Method(NC WAM)analyses of existing and reference stream systems at the Site(NC SFAT 2015 and NC WFAT 2010)(see Table 1).

The Site is located approximately 3.5 miles southeast of Snow Camp and 6 miles north of Silk Hope in southern Alamance County near the Chatham County line (Figure 1,Appendix B). Prior to construction, Site land use consisted of disturbed forest and agricultural land used for livestock grazing and hay production. Livestock had unrestricted access to Site streams,which had been relocated to the floodplain edge, ditched, impounded, trampled by livestock, eroded vertically and laterally, and received extensive sediment and nutrient inputs from stream banks and adjacent pastures. Approximately 60 percent of the stream channel had been degraded contributing to sediment export from the Site resulting from mechanical processes such as livestock hoof shear.In addition,streamside wetlands were cleared and drained by channel downcutting and land uses. Preconstruction Site conditions resulted in degraded water quality, a loss of aquatic habitat, reduced nutrient and sediment retention, and unstable channel characteristics (loss of horizontal flow vectors that maintain pools and an increase in erosive forces to channel bed and banks). Site restoration activities restored riffle-pool morphology aiding in energy dissipation,increased aquatic habitat, stabilized channel banks,and will greatly reduce sediment loss from channel banks. 1.3 Project Components and Structure Site restoration activities generated 3058 Stream Mitigation Units (SMUs) and 0.76 Wetland Mitigation Units(WMUs)as the result of the following: • 1738 linear feet of Priority I stream restoration • 3299 linear feet of stream enhancement(Level II) • 0.54 acre of riparian wetland restoration • 0.44 acre of riparian wetland enhancement Additional activities that occurred at the Site included the following. • Installation of a marsh treatment area to treat drainage prior to entering UT1. • Fencing the entire conservation easement by leaving some pre-existing fencing,removing fencing, and installing additional fencing. • Planting 8.11 acres of the Site with 8600 stems(planted species and densities by zone are included in Table 5 [Appendix C]). • Removing a small,abandoned farm pond by 1)notching the dam to dewater;2)removal of the dam to the elevation of the adjacent floodplain; 3)excavating sediment that was unsuitable for channel bank construction; 4) backfilling areas of sediment removed with soil suitable for channel construction(as necessary);5)excavation of the design channel,6)stabilization of the channel with coir matting, seed,and mulch; and 7)installation of structures. Site design was completed in February 2018.Construction started on July 25,2018 and ended within a final walkthrough on September 6, 2018. The Site was planted in December 2018-January 2019. Completed project activities, reporting history, completion dates, project contacts, and background information are summarized in Tables 1-4(Appendix A). 1.4 Success Criteria Project success criteria have been established per the October 24, 2016 NC Interagency Review Team Wilmington District Stream and Wetland Compensatory Mitigation Update. MY2(2020)Monitoring Report(Project No. 100015) page 3 Major Hill Stream and Wetland Restoration Site Restoration Systems,LLC Alamance County,North Carolina January 2021 1.4.1 Stream Success Criteria From a mitigation perspective, several of the goals and objectives are assumed to be functionally elevated by restoration activities without direct measurement. Other goals and objectives will be considered successful upon achieving vegetation success criteria.The following summarizes stream success criteria. • All streams must maintain an Ordinary High-Water Mark(OHWM),per RGL 05-05. • Continuous surface flow must be documented each year for at least 30 consecutive days. • Bank height ratio (BHR)cannot exceed 1.2 at any measured cross-section. • Entrenchment ratio(ER)must be no less than 1.4 at any measured riffle cross-section. • BHR and ER at any measure riffle cross-section should not change by more than 10% from baseline condition during any given monitoring period. • The stream project shall remain stable and all other performance standards shall be met through four separate bankfull events,occurring in separate years,during the monitoring years 1-7. 1.4.2 Wetland Success Criteria The following summarizes wetland success criteria. • Saturation or inundation within the upper 12 inches of the soil surface for,at a minimum, 10 percent of the growing season,during average climatic conditions According to the Soil Survey of Alamance County,the growing season for Alamance County is from April 17 — October 22 (USDA 1960). However, the start date for the growing season is not typical for the Piedmont region;therefore,for purposes of this project gauge hydrologic success will be determined using data from March 1 - October 22 to more accurately represent the period of biological activity. Based on growing season information outlined in the Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Eastern Mountains and Piedmont Region (USACE 2010), this will be confirmed annually by soil temperatures exceeding 41 degrees Fahrenheit at 12 inches depth and/or bud burst. Target hydrological characteristics include saturation or inundation for 10 percent of the monitored period (March 1-October 22), during average climatic conditions. During years with atypical climatic conditions, groundwater gauges in reference wetlands may be used for comparison to the Site; however, reference gauge data will not be tied to success criteria. These areas are expected to support hydrophytic vegetation. If wetland parameters are marginal as indicated by vegetation and/or hydrology monitoring,a jurisdictional determination will be performed. The jurisdictional determination will not supersede monitoring data, or overturn a failure in meeting success criteria; however, this information may be used by the IRT, at the discretion of the IRT,to make a final determination on Site wetland re-establishment success. 1.4.3 Vegetation Success Criteria The following summarizes vegetation success criteria. • Within planted portions of the site,a minimum of 320 stems per acre must be present at year 3;and a minimum of 210 stems per acre must be present at year 7. • Trees must average 7 feet in height at year 5,and 10 feet in height at year 7. • Planted and volunteer stems are counted,provided they are included in the approved planting list for the site;natural recruits not on the planting list may be considered by the IRT on a case-by-case basis. • Any single species can only account for 50%of the required stems within any vegetation plot. MY2(2020)Monitoring Report(Project No. 100015) page 4 Major Hill Stream and Wetland Restoration Site Restoration Systems,LLC Alamance County,North Carolina January 2021 2.0 METHODS Monitoring requirements and success criteria outlined in this plan follow the October 24, 2016 NC Interagency Review Team Wilmington District Stream and Wetland Compensatory Mitigation Update. Monitoring will be conducted by Axiom Environmental, Inc. Annual monitoring reports of the data collected will be submitted to the NCDMS by Restoration Systems no later than December 31 of each monitoring year data is collected. The monitoring schedule is summarized in the following table. Monitoring Schedule Resource Year 1 Year 2 Year 3 Year 4 Year 5 Year 6 Year 7 Streams Wetlands Vegetation Macroinvertebrates Water Quality Visual Assessment Report Submittal 2.1 Stream Monitoring Annual monitoring will include development of channel cross-sections and substrate on riffles and pools (Figure 2, Appendix B). Data presented in graphic and tabular format include 1) cross-sectional area, 2) bankfull width, 3) average depth, 4) maximum depth, and 5) width-to-depth ratio. Longitudinal profiles were monitored for as-built; however, profiles will not be measured routinely unless monitoring demonstrates channel bank or bed instability, in which case, longitudinal profiles may be required by the USACE along reaches of concern to track changes and demonstrate stability.

Stream morphology and water quality data is available in Appendix D. 2.2 Wetland Monitoring Six groundwater monitoring gauges were installed within the drained pond area and the remaining wetland restoration areas to take measurements after hydrological modifications were performed at the Site(Figure 2, Appendix B). Hydrological sampling will continue throughout the entire year at intervals necessary to satisfy jurisdictional hydrology success criteria. In addition, an on-site rain gauge will document rainfall data for comparison of groundwater conditions with extended drought conditions and a trail camera was installed to confirm overbank flooding events. Growing season soil temperatures will also be documented using a continuously logging soil temperature probe, this data will be provided with wetland hydrology data. Wetland Monitoring Summary Parameter Method Schedule/Frequency Number/Extent Data Collected 6 gauges spread Soil temperature at the Wetland Groundwater As-built,Years 1,2, throughout beginning of each monitoring Restoration gauges 3,4,5,6,and 7 restored period,groundwater and rain wetlands data for each monitoring period Summary of Monitoring Period/Hydrology Success Criteria by Year Year Soil Temperatures/Date Bud Monitoring Period Used for 10 Percent of Burst Documented Determining Success Monitoring Period 2019(Year 1) March 1,2019* March 1-October 22 24 Days (235 days) 2020(Year 2) March 1,2020** March 1-October 22 24 Days (235 Days) *An onsite soil temperature data logger installed 12 inches below the ground surface read 47.90°F on March 1, and the soil temperature remained well above 41°F thereafter. **An onsite soil temperature data logger installed 12 inches below the ground surface read 48.13°F on March 1, and the soil temperature was well-above 41°F the weeks prior and thereafter. Additionally,bud bursts were documented on March 2. Five of the six groundwater gauges met success criteria for the year 2 (2020) monitoring period. Year 2 (2020) groundwater gauge data and graphs are located in Appendix E. Gauge 2 was inundated/saturated for 19 days,or 8.0 percent of the growing season. 2.3 Vegetation Planting occurred in December 2018-January 2019 within 8.11 acres of the Site and included 8600 stems (planted species and densities by zone are included in Table 7 [Appendix C]).After planting was completed, an initial evaluation was performed to verify planting methods and to determine initial species composition and density. In early January 2020, a winter-time visual assessment of the site was performed, and it was determined that although Year 1 (2019)vegetation data, including random transects, showed a high density of trees, a light supplemental planting would help ensure the long-term success in several areas. On January 31,2020, three areas that visually exhibited low stem density and/or poor vigor were supplementally planted(Figure 2, Appendix B). During the supplemental planting effort approximately 370 stems were planted across 1.20 acres(approximately 300 stems per acre). As the planting was designated for visual purposes and was MY2(2020)Monitoring Report(Project No. 100015) page 6 Major Hill Stream and Wetland Restoration Site Restoration Systems,LLC Alamance County,North Carolina January 2021 not an effort to increase stem density data,no stems were planted within permanent vegetation plots. The following table lists species included in the supplemental planting list. Preparation included the application of 100 lbs of lime, 50 lbs of fertilizer, and 3 lbs of seed to stabilize bare areas. In addition,three random vegetation transects were measured including Transect 1(near Plot 6),Transect 2(near Plot 4),and Transect 3 (near Plot 1). After the veg data was complete it was concluded that those areas met required stem densities(Table 9,Appendix C). 2020 Supplemental Planting Species List Species Number of Stems Tag Alder(Alnus serrulata) 20 Chinkapin(Castanea pumila) 20 Hackberry(Celtis occidentalis) 50 Hawthorn(Crataegus marshallii) 20 Crab Apple (Malus angustifolia) 50 Red Mulberry(Morus rubra) 100 Sycamore(Platanus occidentalis) 50 Shumard Oak(Quercus shumardii) 50 Total 370 An assessment was made during the early Fall 2018 to treat fescue within the Dry-Mesic Oak Hickory Forest planting zones to reduce competition with planted stems. Treatment was conducted December 2018 and will continue as needed. Treatments of invasive plant species continued during 2019 throughout the Site.Japanese Stiltgrass and Tree-of-Heaven were high priority during the 2019 invasive treatment season. Restoration Systems will continue to treat and monitor the site for invasive species throughout the monitoring period. See Appendix G (Herbicide Application Forms) for a detailed account of site-wide treatments.

This number is calculated as the easement acreage minus any existing mature tree stands that were not subject to supplemental planting of the understory, the channel acreage, crossings or any other elements not directly planted as part of the project effort. = The acreage within the easement boundaries. = Encroachment may occur within or outside of planted areas and will therefore be calculated against the overall easement acreage. In the event a polygon is cataloged into items 1, 2 or 3 in the table and is the result of encroachment, the associated acreage should be tallied in the relevant item (i.e., item 1,2 or 3) as well as a parallel tally in item 5. = Invasives may occur in or out of planted areas, but still within the easement and will therefore be calculated against the overall easement acreage. Invasives of concern/interest are listed below. The list of high concern spcies are those with the potential to directly outcompete native, young, woody stems in the short-term (e.g. monitoring period or shortly thereafter) or affect the community structure for existing, more established tree/shrub stands over timeframes that are slightly longer (e.g. 1-2 decades). The low/moderate concern group are those species that generally do not have this capacity over the timeframes discussed and therefore are not expected to be mapped with regularity, but can be mapped, if in the judgement of the observer their coverage, density or distribution is suppressing the viability, density, or growth of planted woody stems. Decisions as to whether remediation will be needed are based on the integration of risk factors by DMS such as species present, their coverage, distribution relative to native biomass, and the practicality of treatment. For example, even modest amounts of Kudzu or Japanese Knotweed early in the projects history will warrant control, but potentially large coverages of Microstegium in the herb layer will not likley trigger control because of the limited capacities to impact tree/shrub layers within the timeframes discussed and the potential impacts of treating extensive amounts of ground cover. Those species with the "watch list" designator in gray shade are of interest as well, but have yet to be observed across the state with any frequency. Those in red italics are of particular interest given their extreme risk/threat level for mapping as points where isolated specimens are found, particularly ealry in a projects monitoring history. However, areas of discreet, dense patches will of course be mapped as polygons. The symbology scheme below was one that was found to be helpful for symbolzing invasives polygons, particulalry for situations where the conditon for an area is somewhere between isolated specimens and Appendix C Vegetation Data Table 7.

The Site is located approximately 3.5 miles southeast of Snow Camp and 6 miles north of Silk Hope in southern Alamance County near the Chatham County line. Project attributes are included in the following table. Table 1.Buffer Project Attributes Project Name Major Hill Hydrologic Unit Code 3030002050050 River Basin Cape Fear Geographic Location(Lat,Long) 35.873206,-79.360906 Site Protection Instrument(DB,PG) (2789, 896),(2514, 756),(3143,270),(3150,920) Total Credits(BMU) 402,837 Types of Credits Riparian Buffer Restoration,Enhancement,&Preservation Mitigation Plan Date Apr-18 Initial Planting Date Dec 2018-Jan 2019 Baseline Report Date Mar-19 MY1 Report Date Nov-19 MY2 Report Date Jan-21 MY3 Report Date MY4 Report Date MY5 Report Date The Site drainage area is primarily composed of pasture, forest, agriculture land, and sparse residential property. Impervious surfaces account for less than five percent of the upstream land surface. Prior to construction, Site land use consisted of pasture, hayfields, disturbed forest, and agricultural land used for livestock grazing and hay production.Livestock had unrestricted access to Site streams,and stream banks were eroded vertically and laterally and received extensive sediment and nutrient inputs. Riparian zones in the upper reaches of UT 1 were primarily composed of herbaceous vegetation that was sparse and disturbed due to livestock grazing,bush hogging,and regular land-management activities.The downstream reaches of UT 1 and all of UT 3 were primarily wooded with livestock disturbance to stream channels.UT 2 was the lone tributary not subject to continuous,unrestricted livestock access.Riparian areas immediately adjacent to UT 2 were forested with a fence to protect this area from livestock access. The riparian areas were restored in concurrence with the Major Hill Stream and Wetland Mitigation Site (NC DMS Project ID 10015,SAW-2017-01472)and involved restoring riparian buffers adjacent to restored streams to help reduce non-point source contaminant discharges to downstream waters in the Haw River sub-watershed of Jordan Lake. All riparian areas were assessed by DWR (Katie Merritt and Sue Homewood)during an onsite visit February 20th,2018 to determine viability for buffer mitigation. The Site is protected with a permanent conservation easement. Riparian restoration, enhancement, and preservation area widths adjacent to restored streams extend out to a maximum of 200 feet from the top of MY2(2020)Riparian Buffer Monitoring Report(Project No. 100015) Appendix F:Page 1 Major Hill Stream and Wetland Restoration Site Restoration Systems,LLC Alamance County,North Carolina January 2021 stream banks with a minimum width of 50 from the top of banks. Riparian buffer enhancement and preservation credits generated on this Site are allowed pursuant to 15A NCAC 02B .0295 (o).No riparian restoration areas that are less than 20 feet wide from Top of Banks are used to generate riparian buffer credit. Riparian buffer mitigation credit was not generated in areas that are generating wetland mitigation credit. 2.0 REGULATORY CONSIDERATIONS Credit determination for this Site follows the North Carolina consolidated buffer mitigation rule 15A NCAC 02B .0295,effective November 1,2015 (see Table 2 on the following page and Figure A, Attachment 1). 3.0 RIPARIAN RESTORATION,ENHANCEMENT, & PRESERVATION PLAN This Site was also proposed as a stream and wetland mitigation project; therefore, restoration of riparian areas was accomplished through the goals and methods outlined by the Major Hill Stream and Wetland Mitigation Plan.All applicable federal,state,and local documentation,permits,and/or authorizations were acquired as part of implementing the above-mentioned mitigation plan. Primary goals focused on 1) improving water quality, 2) enhancing flood attenuation and hydrology, 3) improving aquatic resources, and 4) restoring riparian habitat. Completed mitigation provides floodplain connectivity,floodplain resistance, stream stability,sediment transport,surface and subsurface storage and retention, in-stream habitat, riparian habitat and structure, thermal regulation, floodplain biogeochemical processing,and pollutant filtration as well as remove sources of pollutants.The riparian area will be restored through the revegetation of native plant communities. 3.1 Riparian Area Restoration Activities 3.1.1 Site Preparation Soil grading occurred during stream restoration activities. Topsoils were stockpiled during construction activities and spread on the soil surface once critical subgrade was established. The replaced topsoil will serve as a viable growing medium for community restoration to provide nutrients and aid in the survival of planted species. Farm Pond Removal To complete the stream and wetland restoration activities and subsequent riparian buffer restoration, the removal of a small farm pond,—0.58 acres occurred. Stream, wetland and riparian area restoration within the abandoned pond included 1)notching the dam to dewater;2)removal of the dam to the elevation of the adjacent floodplain; 3)excavating sediment that is unsuitable for channel bank construction;4)backfilling areas of sediment removed with soil suitable for channel construction (as necessary); 5) excavation of the design channel, 6) stabilization of the channel with coir matting, seed, and mulch; and 7) installation of structures.

The enhancement MY2(2020)Riparian Buffer Monitoring Report(Project No. 100015) Appendix F:page 4 Major Hill Stream and Wetland Restoration Site Restoration Systems,LLC Alamance County,North Carolina January 2021 area extends a maximum of 200 feet from the top of the bank with a minimum width of 20 from top of banks. A small portion of UT-3 is generating riparian buffer enhancement credit from only one side of the stream. Prior to construction, cattle had access to the entire area; however, the only access point was from the pasture on the northern side of the stream,the Parcel owned by Mr. Lamm. Once fencing was installed to prevent cattle access from Mr. Lamm's parcel to the stream,cattle will no longer be able to access the south side of the stream. This action will result in compliance with 15A NCAC 02B .0295 (o)(6), which states that the permanent exclusion of grazing livestock must be done such that the livestock are fenced out of the stream and its adjacent buffer. The southern parcel, which is not apart of the conservation easement, is owned by the Caviness family and is a single-family home. Cattle will not be grazing within their parcel post construction. 3.3 Riparian Buffer Preservation Activities Riparian buffer preservation includes permanently protecting existing riparian buffers from cutting, clearing,filling,grading,and any similar activities that would affect the functionality of the riparian buffer. Areas specified for Preservation at the Site,in accordance with 15A NCAC 02B.0295,are defined primarily as mixed hardwoods, with the number of high-value species above 200 per acre. They are areas where livestock were fenced out prior to construction with little or no historical livestock access. 3.4 Marsh Treatment Area A marsh treatment area was constructed to intercept surface waters draining through agricultural areas before discharging into UT1. The marsh treatment area is excluded from credit calculations. 4.0 ANNUAL MONITORING 4.1 Monitoring Eight vegetation monitoring plots (10-meter by 10-meter) were installed within the Site as per guidelines established in CVS-EEP Protocol for Recording Vegetation, Version 4.2(Lee et al.2008);this covers 3.4% of the area generating riparian buffer restoration credit. Vegetation monitoring will occur annually in the fall (between September and November), prior to the loss of leaves for a period of five monitoring years following planting. Parameters to be monitored include species composition and species density. Visual observations of the percent cover of shrub and herbaceous species will also be documented by photograph. In addition,inspections for beaver and other potential nuisance species will occur throughout the course of the monitoring period. The following table outlines riparian buffer monitoring for this project;monitoring parameter descriptions follow. Table 4.Riparian Buffer Monitoring Required Parameter Quantity Frequency Notes Eight(8)plots Vegetation will be monitored for five years or until Yes Vegetation located across all Annual performance standards are met.Visual monitoring of the restored buffer site will be done all five years.Analysis of vegetation zones. will be recorded using level 2 CVS Monitoring protocol. Yes Project NA Annual Locations of fence damage,vegetation damage,boundary Boundary encroachments,etc.will be mapped. MY2(2020)Riparian Buffer Monitoring Report(Project No. 100015) Appendix F:page 5 Major Hill Stream and Wetland Restoration Site Restoration Systems,LLC Alamance County,North Carolina January 2021 4.2 Performance Standards Performance standards were established to verify that the vegetation component supports community elements necessary for forest development and the maintenance of diffuse flow through the riparian buffer in accordance with North Carolina Division of Water Resources Administrative Code 15A NCAC 02B.0295 (Mitigation Program Requirements for Protection and Maintenance of Riparian Buffers). Performance standards are dependent upon the density and growth of at least four native hardwood tree species where no one species is greater than 50%of the stems. After five years of monitoring, an average density of 260 woody stems per acre, including planted shrubs (silky dogwood and blueberry), must be surviving, and diffuse flow maintained. 15A NCAC 02b .0295 (2)(E) dictates that monitoring for planted stems would also include the health of planted stems. Level 2 CVS monitoring protocol requires the vigor, a determinant of health, of a monitored stem be recorded. If requested, RS will make available during the monitoring years,planted stem health,e.g.vigor. 4.3 Results and Discussion In early January 2020, a winter-time visual assessment of the site was performed, and it was determined that although Year 1 (2019)vegetation data, including random transects, showed a high density of trees, a light supplemental planting would help ensure the long-term success in several areas. On January 31,2020, three areas that visually exhibited low stem density and/or poor vigor were supplementally planted(Figure 2, Appendix B). During the supplemental planting effort approximately 370 stems were planted across 1.20 acres(approximately 300 stems per acre). As the planting was designated for visual purposes and was not an effort to increase stem density data,no stems were planted within permanent vegetation plots. The following table lists species included in the supplemental planting list. Preparation included the application of 100 lbs of lime, 50 lbs of fertilizer, and 3 lbs of seed to stabilize bare areas (see Figure A for planting areas). Supplemental Planting Species List Species Number of Sterns Tag Alder(Alnus serrulata) 20 Chinkapin(Castanea pumila) 20 Hackberry(Celtis occidentalis) 50 Hawthorn(Crataegus marshallii) 20 Crab Apple (Malus angustifolia) 50 Red Mulberry(Morus rubra) 100 Sycamore (Platanus occidentalis) 50 Shumard Oak(Quercus shumardii) 50 Total 370 Based on the number of stems counted, average densities were measured at 467 hardwood tree stems per acre (excluding livestakes, shrubs, pines, and vines) at year 2 (2020). In addition, all plots, including 3 temporary transects within the supplemental planting areas, met success criteria. The following Table 5 summarizes riparian buffer success criteria and Table 6 summarizes all permanent vegetation plot data by species,plot, and year.
