The project main channel is a second order stream with a 2.7 square mile mountainous drainage located on the New River Plateau of the Blue Ridge. Forest and agriculture are the predominant land uses, which includes a mix of pasture for livestock production (horse and cattle), row crop rotations (corn-small grain), vegetable crops (pumpkins and cabbage) and Christmas trees. Most of the project stream channels were straightened and dredged and combined with significant ditching effectively eliminated the seep-influenced riparian wetlands. The Ut to Crab Creek project provided DMS with a unique opportunity to expand and improve habitat for the Southern Appalachian bog turtle habitat. A faunal survey conducted in 2012 (MY03) by the NCWRC indicated successful movement of the project site in this direction. A portion of the project known as the Ennice Meadow Bog (State Natural Heritage Area (SNHA) Site ID 545) also serves as a site for rare bog/wetland plants and is a N.C. Natural Heritage Program Area of Natural Significance. Wetland and buffer community improvements included plugging ditches, grading, and replanting with native plant species. By improving riparian buffers and aquatic habitat and stabilizing actively degrading channel reaches, the UT to Crab Creek project is addressing the two most significant LWP-identified problems adversely affecting water quality in the watershed: degradation of riparian habitat and sedimentation. Restoration of the project main channel included the replacement of a failing and undersized culvert with a large open bottom arch culvert. This enabled channel bed continuity and allows for significantly improved aqua tic organism transport between the lower portion of the project and the upstream reaches. Site hydrology and sediment transport have also been positively influenced by this upgrade. Beaver activity is strong on the site and beaver management has been conducted throughout the monitoring period. Southern Appalachian bog wetland natural communities are characterized by a mosaic of patchy shrub assemblages and meadows. Because of this, the wetland planting plan consisted of a low density shrub assemblage with various sedges and rush species resulting in a herbaceous dominated system with woody density targets far lower than those of typical mitigation. This warranted a sampling methodology in the form of large random circular plots (100 sq. meter plot size was deemed too small given the lower woody density targets), which were counted during monitoring years two and five. In these boggy areas, the woody stem density ranged from 61to 627 stems per acre (with a mean of 323 stems per acre) in year 5 and is accompanied by a dense herbaceous layer. The bog features on the site possess the distribution of strata and densities that meet or exceed those targeted in the planting plan. Project Goals and Objectives (as stated in the mitigation plan): The restoration goals for this project are as follows:  Improve water quality for Crab Creek, which is categorized by NCDWQ as Class C, Trout Waters (Tr);  Enhance and preserve riparian buffers to a headwater trout stream;  Enhance aquatic and terrestrial habitat along an intact stream corridor;  Improve wetland functions by connecting and expanding the following wetland communities: Swamp Forest-Bog Complex, Southern Appalachian Bog, and Montane Alluvial Forest and;  Improve and expand Southern Appalachian Bog wetland habitat for the Bog Turtle. The objectives that must be accomplished to reach these goals are:  Restore 4,026 linear feet of stable stream channel with the appropriate pattern, profile, and dimension to support a gravel transport system;  Re-establish the natural stream features (bed heterogeneity) to restore diverse aquatic habitat;  Improve aquatic organism passage and habitat corridor continuity b y replacing an existing culvert;  The conversion of existing croplands into Swamp Forest Bog-Complex Community and Southern Appalachian Bog Community. Page 3 of 37 Success Criteria (as indicated in the mitigation plan): Note – Pertinent to wetland vegetation criteria, the Appalachian Bog community type outside of the immediate stream floodplain was in keeping with the species distribution and structure identified in Schafale and Weakley (third approximation) and species identified by NCNHP for this community t ype in the region. This included a herbaceous dominated meadow bog with sporadic shrub species at densities lower than other typical mitigation community types. Woody shrub densities based on the planting plan were less than 50 stems per acre. See pages 22-23 of the approved restoration plan and planting plan sheets 15 -18 for reference. Feature Success Criteria Stream Stability Dimension – Cross-section measurements should show little or no change from the as- built cross-sections. If changes do occur, they will be evaluated to determine whether they are minor adjustments associated with settling and increased stability or whether they indicate movement toward an unstable condition. Pattern – Measurements associated with the restored channel pattern shall be taken on the section of the stream included in the longitudinal profiles. These will include belt width, meander length, and radius of curvature. Subsequently, sinuosity, meander width ratio, radius of curvature, and meander length/bankfull width ratio will be calculated. Profile – Longitudinal profiles will be conducted on the entire length for both UT1 and UTCC-US. Measurements will include slopes (average, pool, riffle) as well as calculations of pool-to-pool spacing. Annual measurements should indicate stable bedform features with little change from the as-built survey. The pools should maintain their depth with lower water surface slopes, while the riffles should remain shallower and steeper. Stream Riparian Vegetation Riparian vegetation must meet a minimum survival success rate of 320 stems/acre after five years. If monitoring indicates that the specified survival rate is not being met, appropriate corrective actions will be developed to include invasive species control, the removal of dead/dying plants, and replanting. Wetland Hydrology Wetland hydrology will be considered established if well data from the site indicate that groundwater is within 12 inches of the soil surface for 5% of the growing season during normal weather conditions. The growing season was taken from Ashe County; the elevation for Alleghany County was approximately 1,000 feet difference in elevation than the project site. According to the NRCS, the growing season is considered to be the period with a 50% probability that the daily minimum temperature is higher than 28 ° F. The growing season for Ashe County extends from May 2 to October 5 for a total of 157 days (USDA,NRCS 1985). Based on this growing season, success will be achieved at the project site if the water table is within 12 inches of the soil surface for 8 consecutive days or more during the growing season. Wetland Vegetation Survival of planted species must be 320 stems/acre at the end of five years of monitoring. Non-target species must not constitute more than 20% of the woody vegetation based on permanent monitoring plots. Management actions such as controlling invasive species, removing dead/dying plants and replanting will be undertaken as necessary. The bog features on the site possess the distribution of strata and densities that meet or exceed those targeted in the planting plan. Large random circular plots were counted during monitoring years two and five. In these boggy areas, the woody stem density ranged from 61to 627 stems per acre (with a mean of 323 stems per acre) in year 5 and is accompanied by a dense herbaceous layer.

Morphological measurements indicate that the project dimension and profile have remained stable with little change in the cross sections. The bed features have maintained their as-built distribution and diversity. Trends of profile degradation or aggradation are absent. Riffle substrate distributions are being maintained on the project main stem in the range of coarse to very coarse gravel. A total of five bank full events have been documented at the project site with more unrecorded events very likely. Improved instream aquatic habitat is evidenced by the presence of spawning mountain redbelly dace (Phoxinus oreas), observed during the summer of 2014 (https://www.youtube.com/watch?v=0Z3CwDPh6io&feature=youtu.be). Redbelly dace are considered an indicator of good water quality due to their sensitivity to pollutants, including sediment, and the need for stable habitat. Vegetation - The monitored vegetation plots revealed that the planted vegetation is growing well Mean density of planted streamside vegetation is 243 stems per acre (with a range of 121 to 566). The inclusion of natural recruits results in a mean of approximately 700 stems per acre (with a range of 243 to 1700). Wetlands - Groundwater monitoring results across the site indicate that, with the exception of the area around UTC-1, groundwater hydrology is meeting success criteria. Sphagnum moss (Sphagnum sp.), a bog indicator plant species, is being observed in the wetland restoration areas along the main stem. Sphagnum moss is a sensitive species that serves as a key component in the Southern Appalachian Bog system. In June 2012 (MY03) a team of biologists led by the NCWRC conducted a survey for bog turtles and herpetofauna and found toads, frogs, turtles and snakes in the wetland restoration areas. While individual bog turtles were not found during the survey, suitable bog turtle habitat (deep, wet soils and burrowing opportunities) was noted. Summary - Overall the streams, wetlands, and the site's vegetation condition are indicative of project success. The stream is functioning as designed and has not developed any significant problems. The project has provided a great deal of floodplain ecological improvement compared to pre-construction conditions, and is providing a healthy and functional buffer to its waters amidst ongoing intensive agricultural activities. The Ut to Crab Creek mitigation site has met its success criteria and the DMS recommends the project for closure with the requested 4, 810 SMUs and 13.15 WMUs. Contingencies None.

It is located within HUC 05050001030020 (Little River and tributaries), which is listed as a Targeted Local Watershed (TLW) in the 2009 New River Basin Restoration Priorities (RBRP) plan. This TLW is located within the Little River and Brush Creek Local Watershed Plan (LWP) area. It is 77 square miles in area, comprising a predominantly rural landscape of private forest lands and small to medium-sized cattle and tree farms. The Little River TLW also includes the urban/suburban area around the Town of Sparta. Based on information in the 2009 RBRP document, the TLW is characterized by 41% agriculture, 52% forest cover, eight percent developed area, 27 animal farms, and 41% degraded (non-forested) riparian buffer area. The watershed includes 59 natural heritage element occurrences (NHEOs), NC Wildlife Resources Commission (WRC) designated priority aquatic habitat and several areas identified as Significant Natural Heritage Areas (SNHAs) by the NC Natural Heritage Program (NHP). Within the Crab Creek subwatershed alone (in which the subject project is located), there are three meadow bog sites designated as SNHAs due to rare plant species and bog turtle habitat. Links to Watershed Goals and Objectives The table below summarizes major watershed stressors identified by the Little River and Brush Creek LWP effort, recommended management strategies to address the stressors, and how the UT Crab Creek project contributes to meeting these goals/strategies. [Note: the list of major stressors comes from the LWP Summary of Findings & Recommendations, which focused on the Bledsoe Creek subwatersheds (focus area selected by the LWP stakeholder team). These subwatersheds are much more urban/developed than the UT Crab Creek project catchment. Only those stressors pertinent to the UT Crab Creek subwatershed are included in the table below. Stressors and Issues Management Strategies UT Crab Creek Project Unstable stream banks; degraded aquatic habitat (Trout waters) Stream restoration/enhancement projects; livestock exclusion fencing Restored approximately 4,200 linear feet of stream channel; replaced farm road culvert with bottomless arch culvert to improve aquatic habitat Degraded (non-forested) riparian buffers Buffer restoration/enhancement projects Restored /enhanced over 4,200 l.f. of riparian buffer; preserved over 2,000 l.f. of headwater stream buffer Cattle grazing; livestock access to streams Fencing and alternate water; agricultural BMPs Restored stream channel and riparian buffer on a historically grazed site (horses; cattle) Excessive sediment and nutrient inputs (and associated aquatic habitat and water quality impacts) Stream restoration/enhancement; livestock fencing; agricultural BMPs Restored/enhanced over 4,200 l.f. of stream channel and buffer Degraded wetlands, including bog turtle habitat Buffer preservation and restoration; wetland restoration/enhancement and preservation Restored 10.1 acres and preserved 7.9 acres of riparian/non-riverine wetland (swamp forest-bog complex and Southern Appalachian bog); preserved over 2,000 l.f. of headwater stream channel and riparian corridor APPENDIX A - Watershed Planning Summary Watershed Context Summary In addition to the UT to Crab Creek project, there are currently three other DMS mitigation projects within this TLW: Glade Creek (#854), an approximately 2,800-ft stream restoration and 780-ft stream preservation project currently in monitoring year 5; Glade Creek II (#92343), totaling 2,450 feet of stream restoration/enhancement and 0.8 acres of non-riverine wetland preservation, currently in construction; and Sparta Bog (#349), a 12-acre bog preservation site that is in long-term management. All projects are located on tributaries of the Little River upstream of Crab Creek’s confluence with the Little River. There are also five NC Clean Water Management Trust Fund (CWMTF) projects that have been implemented within the TLW, including stormwater BMPs in the Town of Sparta and buffer restoration on a tributary to upper Little River. Per data provided by the NC Division of Soil & Water Conservation as of March 2015, there are no documented agricultural BMP projects associated with stream or riparian restoration and enhancement in the 14-digit HU.
