The La Grange Bank Parcel is located at the southwest intersection of NC 903 and Old Jason Road (SR 1501), north of LaGrange, in Lenoir County, North Carolina (Figures 1 and 2). The latitude/longitude coordinates of the site are approximately 77° 44.315 W and 35° 20.588N. The purpose of the nutrient mitigation bank is to improve water quality within the Neuse River Basin by reducing nutrient and sediment inputs to the watershed and provide off-site mitigation for development requiring nutrient offsets. The Bank Parcel is located within the Middle Neuse Watershed (HUC: 03020202). The site drains to Meeting House Branch (Stream Index # 27-72-3), which drains into Bear Creek (Stream Index # 27-72-(0.1)), a major tributary to the Neuse River. According to the NC Division of Water Quality Basinwide Information Management System, Meeting House Branch is classified as C; Sw, NSW. The Bank Parcel is 3.39 acres, including 0.87 acres of riparian buffer and 2.52 acres of nutrient offset acreage (Figures 3 and 4). The Bank Parcel was established under the terms and conditions of the GES Neuse River Basin Umbrella Mitigation Bank. The project site was in agricultural cropland until 2009 and was first planted with character species during March of 2010. The first annual monitoring report was submitted to the Division of Water Resources in 2013; this is the third annual monitoring report. In 2015, a second mitigation bank was established immediately adjacent to the La Grange Bank Parcel. This bank is the La Grange Mitigation Bank, Phase II and will be monitored separately from the initial La Grange Bank Parcel and will be maintained with a separate mitigation credit ledger. Monitoring and Results for Year 2015 As specified in the La Grange Bank Parcel Development Package (BPDP), this report represents the third year of vegetative monitoring. The BPDP requires the submission of an annual monitoring report each of five successive years. The next (fourth) annual report will be submitted no later December 31, 2016. The La Grange Bank Parcel was initially planted with character trees in 2010 and 2011 at a rate of 413 seedlings per acre (Table 1). Supplemental plantings were done in 2012 and 2013 at a rate of 108 and 103 seedlings per acre, respectively. Thus prior to the submission of this first annual monitoring report an estimated total of 624 seedlings per acre had been planted on the 3.39 -acre parcel. In each of the two monitoring plots in the La Grange Parcel, tree stems were recorded by species in September 2015. Plot locations are mapped in Figure 5. Vegetation plot photo points were located at the northwestern corner of the plots (Figure 6). During the 2015 monitoring effort, a total of 45 seedlings representing ten tree species were recorded in the two monitoring plots, LAG -1 and LAG -2. The total average density was 910.9 trees per acre (Table 2). Thirty-eight of the 45 trees within the plots were from seedlings planted by GES; average planted stem density was 769.2 tree stems per acre (Table 3). Thus eighty-four percent of the trees were planted species; bald cypress (Taxodium distichum) accounted for 39.5 percent of the planted seedlings followed, in decreasing order by river birch (Betula nigra), black gum (Nyssa sylvatica), and sycamore (Plantanus occidentalis). White oak (Quercus alba), swamp chestnut oak (Quercus michauxii) and cherrybark oak (Quercus pagoda) each accounted for less than three percent of planted species total. (Table 4). Red maple (Acer rubrum), loblolly pine (Pinus taeda) and black oak (Quercus velutina) became established via natural colonization. Persimmon, green ash, yellow poplar, turkey oak, live oak, and pond cypress were planted on the La Grange Parcel but were not recorded in the monitoring plots. Stems of river birch and sycamore had the greatest average height among the ten species found within the plots (Table 5). A comparison of second year (2014) monitoring data to the third year (2015) indicted an increase in total stem density per acre in the monitoring plots from 870.4 to 910.9 stems per acre (Table 6). For planted species, stem density increased by 161.9 stems per acre but for naturally colonizing species, stem density decreased by 121.5 stems per acre. The increase in stem density of planted species is most likely due to resprouting from heavily grazed (rabbits and deer graze heavily at the site) stems in 2014 and/or an undercount during the second year monitoring effort. The decrease in stem density of naturally colonizing species was attributable to a decline in red maple stems possibly due to grazing. For both total stem density and planted stem density, the 320 trees per acre success criterion was well exceeded. Overall Condition, Maintenance and Supplemental Plantings Vegetation establishment and growth has been good at the La Grange parcel. Growing conditions, e.g, adequate rainfall, length of growing season and fertile soils, have been advantageous since the initial plantings were undertaken. The height of some seedlings, especially river birch, planted in 2010, now exceeds 3 in with diameters (dbh) of 8-10 cm. Other species exhibit slower growth but are performing as expected. Browsing by deer has been moderately problematic for seedlings in exposed areas and especially problematic for green ash seedlings. There has been some evidence of depredation by rabbits and possibly beavers and other rodents. Annual, herbaceous weed growth has been excessive; this would expectedly result rd in above -ground and below -ground competition with planted seedlings. However, the weeds likely afford the seedlings some greater advantage by protecting them from browsing deer. In an effort to control rabbit and rodent populations, two 15 -foot tall hawk perches were installed on the site. Signage has been installed at key access locations identifying the Bank Parcel as a conservation area, contact information and listing activities that are not allowable as per a conservation easement.
