Seven Lakes CC is located south of Seven Lakes Drive, north of West End, Moore County, NC. The 7.53 acre driving range is located on E. Devonshire Avenue adjacent to the clubhouse (Figure 1). Seven Lakes CC secured a United States Army Corps of Engineers (USACOE) Nationwide Permit (NWP) No. 39 and the corresponding Division of Water Quality General Water Quality Certification (GC 3631) for the construction of a new driving range. A DWQ compliance inspection of the permitted work at the driving range in early 2008 resulted in a Notice of Violation (NOV), noting the following observations: mechanized clearing where only hand clearing was authorized, an unpermitted excavated ditch within wetlands and sedimentation impacts. A USACOE compliance inspection resulted in a letter of non-compliance, which cited mechanized land clearing of jurisdictional wetlands beyond the permitted area, unauthorized stream relocation, failing erosion control measures and sedimentation into Waters of the U. S. Both the USACOE and the DWQ required that a restoration plan be prepared and implemented in order to mitigate for the unauthorized activities. Seven Lakes CC took corrective action towards restoring jurisdictional areas on, and adjacent to, the driving range site immediately after receiving the agencies' NOVs. Silt fencing was installed in order to stabilize the site and prevent further sedimentation. Seven Lakes CC then hired Dr. J. H. Carter III & Associates, Inc. (JCA) to prepare the required restoration plan and consult with the agencies. Figure 1. Location of the Seven Lakes Country Club, Moore County, North Carolina. JCA submitted the Wetland and Stream Restoration Plan for Seven Lakes Country Club Driving Range, West End, Moore County, North Carolina, to the USAGE, the DWQ and the NC Division of Land Resources on 6 June 2008. The USACOE and DWQ approved the plan in the summer of 2008 and restoration activities were completed by the end of that year. Monitoring of the restoration area is required for a minimum of 3 years. This document serves as the monitoring report for the first year. INITIAL RESTORATION MONITORING Three 10x10-meter monitoring plots were established within the herbaceous wetland area on 30 March 2009. The monitoring plots are situated at the northern end, southern end and western side of the headwater wetland (Figure 2). Since the NWP 39 permitted the original forested wetland to be converted to an herbaceous wetland, only herbaceous species, prevalence and percent cover will be monitored. Shrubs and tree species will be recorded if present; however, trees will not be mapped or tracked for survivorship. The herbaceous wetland will be periodically mowed/maintained as permitted. Monitoring Data Vegetation data was collected in the 3 monitoring plots on 30 March 2009 in order to establish the initial baseline conditions onsite. All three plots were revisited on 30 September, 2009 and the following data summarizes the most recently observed conditions at each plot. Plot #1 had 1-2 percent (%) bare ground. This represents no change from the March 2009 baseline condition. Wool grass (Scirpus cyperinus), clustered beaksedge (Rhynchospora glomerata) and bunched beaksedge (R. cephalantha) were the most abundant species, each with 25-50% cover. Small-headed beaksedge (R. microcephala) and velvet witchgrass (Dichanthelium scoparium) were both also fairly common in the plot, each with 5-10% cover. Plot #1's species composition became more diverse compared to March 2009. The September 2009 monitoring found an additional 12 species in Plot #1, bring the total to 30 species within the plot. Plot #2 had 2-5% bare ground representing a significant decrease from the March 2009 baseline of 50-75%. The decrease in bare ground demonstrates that the restoration should be successful at the end of the 3 year monitoring period. The dominant species were wool grass at 25-50% and bunched beaksedge at 10-25% cover. Both of these species increased significantly in overall density within the plot. Six new species were observed during the September 2009 investigation, bringing the total species count to 23 for the plot. Plot #3 had 2-5% bare ground, a significant decrease from the March 2009 baseline of 75- 95%. The reduction in bare ground and return of herbaceous vegetation again illustrates that the impacted wetland is recovering. Warty panic grass (Panicum verrucosum), bunched beak sedge and swamp sunflower (Helianthus angustifolius) were the most abundant plants present, each with 10-25% cover. Plot # 3 showed the most improvement in species diversity. Sixteen new species were added during the September 2009 survey, bringing the total species count to 24 for the plot. Conservation easement A small area of forested wetland was placed in a conservation easement as part of the permit stipulations. A few trees from the outer edge of this area were cut down during the initial conversion of the wetland to an herbaceous system. As part of the restoration effort approximately 20 each of pond pine (Pinus serotina), tulip poplar (Liriodendron tulipifera) and swamp blackgum (Nyssa sylvatica) were planted to mitigate for the few trees that were cut inside of the conservation easement area. These trees were inspected in September 2009 and all were surviving. The number of trees planted will overcompensate for the few trees that were incidentally cut in the conservation easement, even with natural thinning over time. These trees will continue to be monitored periodically during site visits and replaced as necessary if mortality is observed. 4 Vegetation Data Collection Seven Lakes Driving Range - Plot #1 PLOT] Monitor Initial Data Year 1 Scientific Name Common Name Indicator 3/30/2009 9/30/2009 bare ground/ open water --- 1-2% 1-2% Acer rubrum red maple seedlings FAC X Andropogon glomeratus bushy bluestem FACW+ X Andropogon virginicus broomsedge bluestem FAC- X O Aroma arbutifolia red chokeberry FACW X 1-2% Arundinaria tecta switch cane FACW X --- Baccharis halimifolia sea-myrtle FAC 1-2% Cyperus erythrorhizos red-root flatsedge OBL X O Dichanthelium scoparium velvet witchgrass FACW 5-10% 5-10% Eleocharis sp.

X - Indicates presense in plot, not at a full percentage yet Clubhouse at SUMMARY AND DISCUSSION The headwater wetland at the Seven Lakes CC was converted from a forested wetland to herbaceous wetland as part of the permitted activities and will be maintained as a herbaceous wetland as permitted. The wetland as a whole shows evidence of sufficient hydrology. In most areas the soils are saturated to the surface or slightly inundated by up to one half inch of water. Since sufficient wetland hydrology is defined as saturation or inundation to the surface for at least 5% of the growing season, the observed high water table within the wetland indicates that the requirements for hydrology are being met. Native soils were uncovered in areas where unauthorized fill and/or sediments were removed. These restored areas met the criteria to qualify as hydric soils, with either dark mucky organic soils (10YR 2/1) or mineral soils with low chromas (1 OYR 511) and evidence of redoxomorphic activity (mottling of oxidized root channels) at, or near, the surface. All 3 plots are recovering well and have established good herbaceous coverage and diversity. They also have shown signs of stable hydrology and sufficient wetland soils. The remaining areas of the wetland that were not impacted by the unauthorized activities, appear healthy. The herbaceous plant life appears lush and dense, containing species composition similar to the reference plots. Soils were similar throughout, being composed of organic mucks that were saturated to the surface and in some areas slightly inundated. REFERENCES Mullin, W. and Dr. J. H. Carter III. 2008.
