Hyder Pasture is a recently-restored fen near Flat Rock, North Carolina. It contains a population of the federally-endangered Bunched Arrowhead (Sagittaria fasciculate), a small herbaceous plant typically found in saturated soils near groundwater seeps. Bunched Arrowhead are found in only eleven locations in the world, all in North and South Carolina. This study represents the first chemical assessment of water and soil at the site since the restoration and adds to the growing body of work aimed at understanding the requirements of sustainable Bunched Arrowhead populations. Water samples were analyzed for major ions, pH, and temperature. Soil texture was similar throughout the study area, consisting of sandy loams and loamy sands. Cation Exchange Capacity ranged from 19.5 to 38.8 Cmolc kg-1. Areas of the restoration site that had top soil removed in order to form topological depressions were found to have lower soil organic content (>4.01% SOC) than undisturbed areas (6.02% to 12.66% SOC). Soils were acidic, with pH ranging from 4.45 to 4.93. These data from Hyder Pasture were then compared to established bunched arrowhead populations at other sites.
