Yellow Nutsedge Culm Density, Yellow Nutsedge Tuber Density, and Percent Native Cover in Disturbed and Undisturbed Plots in 1997, 2002, and 2008 on St. Catherine's Island, GA

Field data was collected in 1997, 2002, and 2008 for two study locations on St. Catherine's Island, Georgia. At each study site in 1997, (North Beach (NB) and McQueen's Inlet (MQ)), a 0.2 ha area was surveyed for hog (Sus scrofa) soil disturbances. These disturbances were designated as ‘disturbed plots’ (Exp). Paired ‘undisturbed plots’ (Ctr) were established adjacent to the 'disturbed plots'. Within these paired plots, we randomly subsampled the following variables using 0.01 m2 quadrats: yellow nutsedge (Cyperys esculentus) culm density, yellow nutsedge tuber density (2002 and 2008 only), and percent live cover of native species. Subsample number varied with size of disturbance, and data were averaged resulting in one value per disturbance. Additional paired plots were added in 2008 to outline new wild hog disturbances.
