The Project is located within the Upper Neuse River Basin Hydrologic Unit and Targeted Local Watershed 03020201050020. This document details riparian buffer and nutrient offset buffer mitigation activities within an approximately 12.14 -acre easement. The easement boundary currently has no signage or marking. Completed project activities, reporting history, completion dates, project contacts, and project attributes are summarized in Tables 1-4 (Appendix A). This report (compiled based on the NC Division of Mitigation Services (NCDMS) Procedural Guidance and Content Requirements for DMS Monitoring Reports Version 1.5 dated 6/8/12) summarizes data for Year 2 (2015) monitoring. The Little Lick Creek Buffer Restoration Project is located in the Little Lick Creek Local Watershed planning area, which is nested in the 700 -square mile Falls Lake watershed. The Project watershed is located within 14 -digit Hydrologic Unit Code (HUC) 03020201050020, which was identified as a Targeted Local Watershed (TLW) in the North Carolina Division of Mitigation Services (NCDMS) 2010 Neuse River Basin Restoration Priority (RBRP) plan and is identified in the 2009 Little Lick Creek Local Watershed Plan (LWP) Upper Neuse Project Atlas (Butler Road). NCDMS developed a LWP for the 21 -square mile Little Lick Creek watershed area that included land use analysis, water quality monitoring, and stakeholder input to identify problems with water quality, habitat, and hydrology. The Little Lick Creek watershed is relatively undeveloped and in an active state of rural to suburban transition with agriculture, forestry, rural, and undeveloped land comprising over 50 percent of the land uses. Durham laws zone this land for intensive development; therefore, this land is rapidly being converted to residential and commercial properties. Little Lick Creek is on the NC Section 303(d) list of impaired water bodies, due to poor aquatic life ratings and low levels of dissolved oxygen as the result of trash dumping, poor maintenance of on-site wastewater treatment systems, small vehicle maintenance and repair operations, outdoor materials storage, grease storage, and wash water disposal. The Little Lick Creek LWP project atlas includes this Project (Butler Road) with identified stressors resulting from anthropogenic activities related to the conversion of 80 percent of the watershed to disturbed land use/land cover with impervious surfaces covering over 14 percent of the watershed. Water quality is influenced due to the watershed slope (6 percent), the presence of moderately erodible soils, and its location with the Triassic Basin ecoregion. This project was identified for riparian buffer and nutrient offset restoration opportunities to improve hydrology, water quality, and habitat. The goals of the Little Lick Creek Project (Butler Road) address stressors identified in the Project watershed and include the following. • Restore riparian buffers associated with Little Lick Creek, a UT to Little Lick Creek, and water conveyances flowing to jurisdictional waters on site. The project goals will be addressed by the following objectives. Reestablish natural vegetation along stream banks and water by planting existing cleared/disturbed land and treating invasive species. Project restoration activities were completed between November 2013 and December 2013 with invasive species controls ongoing. Activities included 1) removal and treatment of invasive species including rose (Rosa sp.), Japanese honeysuckle (Lonicera japonica), and Chinese privet (Ligustrum sinense); 2) mowing and/or clearing of dense areas of loblolly pine (Pinus taeda) seedlings and blackberry (Rubus Little Lick Creek Restoration Project (FINAL) Monitoring Year 2 of 5 (2015) DMS Project No. 92542 November 2015 Durham County, NC page 1 argutus); 3) soil amendments based on recommendations from soil samples analyzed by the NCDA&CS Agronomy Division; and 4) plant community restoration. The implemented mitigation is as follows.

Vegetation Success Criteria An average density of 320 planted hardwood stems per acre must be surviving after five monitoring years in accordance with North Carolina Division of Water Resources Administrative Code 15A NCAC 02B.0242 (Neuse River Basin, Mitigation Program for Protection and Maintenance of Existing Riparian Buffers) (NCDWR 2007). 2.0 METHODOLOGY Annual monitoring data will be reported using the North Carolina Division of Mitigation Services (NCDMS) monitoring template. The monitoring report shall provide a chronology of project data that will facilitate an understanding of project status and trends, population of NCDMS databases for analysis, research purposes, and to assist in decision making regarding project close-out. The following table outlines monitoring requirements for this Project. Monitoring Schedule/Requirements Table Parameter Quantity Frequency Notes 8 CVS plots (see Figure 3 in Annually in Vegetation will be monitored using the Vegetation Appendix B for approximate Monitoring Years Carolina Vegetation Survey (CVS) locations) 1-5 protocols Exotic and nuisance Semi-annual Locations of exotic and nuisance vegetation vegetation will be mapped Locations of fence damage, vegetation Project boundary Semi-annual damage, boundary encroachments, etc. will be mapped Vegetation Monitoring After planting was completed, an initial evaluation was performed to verify planting methods were successful and to determine initial species composition and density. Eight sample vegetation plots (10 - meter by 10 -meter) were installed and measured within the Site as per guidelines established in CVS -DMS Protocol for Recording Vegetation, Version 4.2 (Lee et al. 2008) (Figure 3, Appendix B). Vegetation plots are permanently monumented with 6 -foot metal T -posts at each corner, and a ten foot tall pvc at the origin. In each sample plot, vegetation parameters to be monitored include species composition and species density. Visual observations of the percent cover of shrub and herbaceous species will be documented by photograph. Vegetation plot information for MY2 (2015) was collected in October 2015 Little Lick Creek Restoration Project (FINAL) Monitoring Year 2 of 5 (2015) DMS Project No. 92542 November 2015 Durham County, NC page 2 and can be found in Appendix C. Stem count measurements for MY2 (2015) indicate an average of 425 planted stems per acre across the Project. Six out of eight vegetation plots met success criteria for MY2 (2015) monitoring. Plots 2 and 3 were 2 and 4 stems, respectively, shy of meeting success criteria based on planted stems alone; however, when including natural recruits of green ash (Fraxinus pennsylvanica) and willow oak (Quercus phellos) in Plot 2 and American elm (Ulmus americana) in Plot 3, these plots were above success criteria. Planted stem mortality can be attributed to competition from the dense herbaceous layer. Several large, dense patches of Japanese honeysuckle (Lonicera japonica) was observed throughout the Site. The vines are affecting the vigor of planted woody stems; therefore, treatment is recommended. Additionally, a small patch of Chinese lespedeza (Lespedeza cuneata) was observed in the vicinity of Plot 3, which is attributing to low planted stem counts in this plot. Furthermore, a large patch of blackberry was observed in the northeast portion of the site, near plot 1. The blackberry is dense and appears to be outcompeting several planted stems in this area ( Figure 3, Appendix B).

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. 4 = 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 Ilkley 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 dense, discreet patches. In any case, the point or polygon/area feature can be symbolized to describe things like high or low concern and species can be listed as a map inset, in legend items if the number of species are limited or in the narrative section of the executive summary. % of Mapping Pp g CCPV Number of Combined Vegetation Category Definitions Easement Threshold Depiction Polygons Acreage Acreage 4.
