Title: Tree, shrub, and herb data from 10 Hillslope Project sites located in Macon County, North Carolina, within the Upper Little Tennessee River Basin
Abstract: Vegetation was surveyed on 10 sites in the upper Little Tennessee River watershed in Macon County, North Carolina during the summer of 2012. The sites represent a gradient of development, including forested sites, agricultural sites, and exurban sites. All woody vegetation >2.5 cm diameter at breast height (DBH) was measured and identified within twelve 10 x 10 m plots at each site. Woody shrubs >0.5 m in height and <2.5 cm DBH were counted and identified within a 1x10 m transect in each plot. Herbs and woody plants <0.5m in height were identified and percent cover estimated in 3 1 x 1 m subplots located within each of the larger 10 x 10 m plots.
