For your convenience, the approved Adaptive Plan is included as Attachment 1 to this Addendum. Tract 1 Year 3 Monitoring Observation: In the vicinity of Plot 7, planted stems were exhibiting stunted growth when compared with surrounding plots. Based on observations, the likely cause for diminished growth was competition with dense fescue in the area. Year 4 Adaptive Implementation Measures: The following adaptive management measures have been implemented on Tract 1: 1. A licensed pesticide applicator from Ripple EcoSolutions applied an aquatic safe herbicide on an approximate 0.4 acres in the vicinity of Plot 7 on 8/7/2020. Spray logs are included in Attachment 2. While spraying, care was taken to avoid existing plant stock, however, during the monitoring assessment of the area on October 1P and 12'h of 2020, Axiom noted that several trees in Plot 7 may have been lost to herbicide treatment. 2. Soil tests of this area were taken on 7/9/2020 to check whether soil amendment was needed to aid tree growth and to compare the area with the neighboring Tract 1 soils. The soil test results are included in Attachment 3 as Site N1. Several areas around plot 7 were taken at a depth of approximately 6 inches to create a composite soil of the area. As indicated in the soil test results, the emergent hardwood community in and around Plot 7 (i.e., Site N1) was not recommended for lime treatment. Due to concerns over the lack of growth in the originally planted trees around Plot 7, each tree was planted with one 21-gram Scotts Agriform Fertilizer 20N:10P:5K tablet. The slow -release tablets provide consistent plant -available micronutrients for consistent growth across the planting area with minimal leaching and should aid plant growth. 3. Follow-up planting of the sprayed area was completed 10/29/20 (See Table 1 for the planting list). Fifty containerized plants (one -gallon) were planted at a spacing of 20ft x 20ft and the newly planted stock were flagged. Photos of the new plant stock in the planted area are included as Attachment 4. Table 1. One -gallon tree species and planting numbers used on 10/29/20.

Unlike the Plot 7 area of Tract 1, fescue density and growth was not vigorous and did not seem to be a likely cause for low growth in planted stems in Tract 2. Year 4 Adaptive Implementation Measures: The following adaptive management measures have been implemented on Tract 2: • Soil tests were taken at the site on 7/9/20 and the results are included in Attachment 3. To better diagnose the site, Tract 2 was divided into Side A (south side) listed as N2A in the soils report and Side B (north side) listed as N213 in the soils report. Several soil samples were taken at a depth of approximately 6 inches to create a composite soil of each side. Like Tract 1, lime soil amendment was not recommended in the soils results for the emergent hardwood plants. The same Scotts Agriform fertilizer tablet described for Tract 1 was utilized for new tree plantings in Tract 2 to help improve plant growth. • Follow-up tree planting of the tract was completed 10/29/20 (See Table 1 for the planting list). One -hundred -fifty (150) containerized plants (one -gallon) were planted at a spacing of 20ft x 20ft and the newly planted stock were flagged. Photos of the new plant stock in the planted area are included as Attachment 4. Remaining Implementation Measures In the early Spring of 2021, a non -toxic deer repellent will be applied at least once to the plants on Tract 2 to discourage herbivory. A non -toxic repellent safe for wildlife will be used and timed to coincide with the early budding stage of the newly planted trees. Addendum Attachment 1. Adaptive Management Plan (end Submission - 7/12/2020) Neville Farms Phases 1&2 DWR #2015-0636 Site Overview and History This Adaptive Management Plan is provided to address concerns over planted stem success at the Neville Farms Mitigation Bank Parcel (Site). Watershed Investments NC (WINC), the sponsor, originally planted the site in November -December 2016. The site encompasses 6.15 acres of land along Neville Creek in Orange County North Carolina and is broken into two tracts separated by Neville Creek (See Figure 1 for a map of the site). Site activities consisted of approximately 5.04 acres of riparian restoration and approximately 0.94 acres of riparian preservation. An additional 0.17 acres of Tract 1 is included in the project easement area but is outside the rule -defined riparian buffer zone and, consequently, is not included for either riparian buffer mitigation or nutrient offset credit generation. Year 3 (2019) monitoring data was collected on October 11, 2019 by Axiom Environmental (See Attachmentl). While average density of planted stems per acre were above success criteria of 260 planted stems, in their review of the report, NC Division of Water Resources (DWR) staff raised concerns over limited plant growth at both tracts of the Site (See NC DWR Email in Attachment 2) and prompted a visit to review the site. Staff from Watershed Investments (Mike Herrmann), Axiom Environmental (Phillip Perkinson) accompanied Katie Merritt (DWR) on a visit to the Site on June 111h, 2020 to review plant growth and discuss options for corrective measures. In their visit, deer browsing, competition from existing fescue, and poor soils were all sited as potential causes for limited tree growth in some areas of both tracts. The prevalence of these causes varied between Tract 1 and Tract 2 but raised concerns over planting success at some areas within the Site. No signs of easement encroachment were observed during the visit. The following is a brief summary of observations made of the two tracts during the site visit. Tract 1- Planted stem growth was observed to be meeting success criteria throughout the majority of the mitigation area and numerous natural volunteer plants were observed. Limited plant growth was observed, however, both within Plot 7 and its immediate surrounding area (See Figure 1). In the Plot 7 area dense fescue was established. Additionally, the plot's planted stem viability was the lowest of all the plots (283 stems/acre). Based on field observation, the area of suppressed growth is estimated to be 0.30 acres. Tract 2 — Both plant diversity and growth were limited in most of the easement area except for the area within monitoring Plot #2. Potentially causes for these problems were suggested to be poor soil and plant herbivory. The area affected is shown in Figure 1 and is approximately 1.20 acres. In response to concerns found in the annual monitoring reports and observed during the visit, the following adaptive measures are proposed to, increase planted tree density, provide plant diversity, and address competition from herbaceous plants. Adpative Management Plan Herbaceous competition from fescue was observed to be a likely cause of stunted plant growth on Tract 1. On this tract, herbicide will be used to control fescue. Chemicals labeled safe for use in riparian zones and in aquatic environments will be mixed and applied at rates labeled for treatment of fescue. Precautions will be taken to avoid collateral damage to desirable vegetation (both planted and volunteer). Pesticide application will be conducted by a licensed application specialist and logs will be available upon request. Fescue application will be scheduled soon after approval of this adaptive management plan. Soil testing of Tract 2 is being undertaken to determine whether the site needs soil amendments prior to the container planting. Soil amendment will occur as needed based on soil testing. Possible amendments to the soil include the use of lime to lower acidity and/or fertilization to improve low soil nutrients (e.g., phosphorus, or potassium) while being careful not to over fertilize. Fertility in Tract 1 was not observed to be a problem. To increase planted stem density, planting one -gallon container plants will occur on both tracts 1 and 2. On Tract 2, 150 native hardwood species listed in Table 1 will be planted at a density of approximately 100 stems per acre to fillin areas with low planted stem growth or stunted growth. This density, when combined with existing successful plants, should solidify the likelihood that plantings at the site will meet success criteria defined in the Mitigation Banking Instrument at the site close-out. To assess planting needs, Tract 2 is separated into 2 sides based on topography and existing tree growth. Results from soil tests and existing tree locations on each side will be used to determine where container plants are needed to supplement sparse areas of existing tree growth. Soil amendments will be based on soil test findings. For Tract 1, where the area is smaller, approximately 50 trees will be planted using a more uniform 16-foot spacing. Of the Table 1 species, Acer rubrum (Red Maple) will not be planted on Tract 1 and only used on Tract 2. Planting of both tracts will occur in the Fall/Winter of 2020/2021 and observed over Year 5 of the monitoring period. Due to their more developed root system, the container plants will be better enabled to overcome herbivory that is suspected to be affecting the site. In addition, to discourage herbivory, a deer repellent will be applied at least once to the plants on Tract 2 in the spring of 2021 when trees are in the early budding stage. A non -toxic repellent safe for wildlife will be used. Table 1. Proposed one -gallon tree species (Note: Species availability may result in the substitution of regionally appropriate native species.)
