There were two sets of tracts with the CLCP; a 1.23 -acre set of tracts located off Lower Field Road, north of the NC 903 in the Scuffleton community, and a second set of tracts totaling 19.53 acres located off SR 1004, south of NC 903 in Scuffleton, NC (Figures 1 and 2). With the exception of two tracts, Tract 8 and a mitigation bank expansion tract, Tract 10A, the field monitoring obligations of GES has been completed. New monitoring reports for Tracts 8 and l0A will be submitted separately. This report is the first of five, post - remedial planting report for Tract 8. The riparian buffer and nutrient offset credits generated by the CLCP may be used to offset impacts within Cataloging Unit 03020203 of the Neuse River Basin. Monitoring and Results for Year 2011 As specified in the CLCP Bank Parcel Development Package (BPDP), this report represents the first year of post - remediation vegetative monitoring of Tract 8 of the CLCP. The BPDP requires the submission of an annual monitoring report each of five successive years. Tract 8, a 1.51 acre tract with two monitoring plots, Plots 8A and 813, was included in the initial CLCP project area. However, due to poor survival rates among planted tree species, this tract marginally meet success criteria for stem density. Remedial planting had been undertaken routinely during previous growing season yet the site remained problematic due to its excessively well- drained, sandy soils and grazing by deer. NCDNR - Division of Water Quality personnel visited the site in November 2011 and agreed to a remediation plan for Tract 8 that included planting two new species on site that are well adapted to the excessively drained soils of the tract; turkey oak (Quercus laevis) and longleaf pine (Pious palustris). In January 2012, 600 bareroot turkey oak seedlings and 270 containerized longleaf pine seedlings were planted on Tract 8. These species were supplemental to the previously planted species green ash (Fraxinus pennsylvanica), white oak (Quercus alba), and bald cypress (Taxodium distichum); as well as the volunteer species, loblolly pine (Pious taeda). In each of the two monitoring plots, all character trees were recorded by species in October 2012 according to Carolina Vegetation Survey sampling protocols referred to in the Mitigation Banking Instrument. Plot locations are mapped in Figure 3. Vegetation plot photo points were located at the northwestern corner of the plots (Figure 4). During the October 2012 monitoring effort, a total of 17 trees representing five character species were recorded in the two monitoring plots (Table 1). The total average density was 344 trees per acre; exceeding the 320 trees per acre success criterion. Sixteen of the 17 trees within the plots were from seedlings planted by GES. Thus 94 percent of the trees were planted with one tree, a loblolly pine, established via natural colonization. The species with the highest stem density in the monitoring plots was turkey oak, all of which were planted in January of 2012 (Table 2). This species is well adapted to the sandy soils of Tract 8. A comparison of the October 2012 monitoring results to those of October 2012 (Table 3) indicates an overall stem density increase of 6 percent among plots. By 2012, green ash stems had decreased from 11 stems to 4 stems, loblolly pine from 2 stems to 1 stem and white oak from 2 stems to 0 stems; bald cypress was unchanged with one stem persisting. The remedial planting yielded two new species with the monitoring plots, 8 turkey oak stems and 3 longleaf pine stems. Overall Condition, Maintenance and Supplemental Plantings The 1.51 -acre, Tract 8 continues to be a problematic site due to drought -prone site conditions and grazing by deer. While stem density meets success criteria, sapling growth (height and diameter) is poor. Turkey oak seedlings planting in January 2012 became established with moderate success; less so with newly planted longleaf pine. Most previously planted species declined in survivorship; surviving individuals exhibited poor growth. The 2012 growing season was generally good with adequate rainfall and moderate air temperatures. Annual, herbaceous weeds, especially dogfennel (Eupatorium capillifolium) were robust during 2012; while these weeds compete with seedlings for water and nutrients during the growing season, they may also be beneficial by moderating microsite conditions and providing some refuge from grazing. During the coming 2013 planting season (January through March), GES will conduct supplemental plantings on Tract 8 with site - appropriate hardwood species. Table 1.
