A chemical characterization of water and soil from the newly restored Hyder Pasture fen in Flat Rock, North Carolina was obtained. This represents the first assay performed on the site since the restoration. Little data was available from pre-restoration analysis for comparison. However, what was available was compared to this study to investigate any observable changes. Several methodologies were utilized in order to ascertain prominent chemical features of the system supporting a population of endangered bunched arrowhead (Sagittaria fasciculate). Water samples were analyzed by HP-LC Ion Exchange to determine what nutrients were present in various bodies of water at the site. Soil samples were analyzed by standard CEC procedures to determine the nutrients and potential productivity of the soil after the restoration. Soil organic carbon was determined by the Loss on Ignition(LOI) method. Scanning Electron Microscopy with EDS was employed in order to qualitatively determine the mineralogy of the soil. The scope of this study was to add to the growing body of work aimed at understanding the requirements of sustainable bunched arrowhead populations. Currently, little research is available to aid in predicting the success of wetland restorations focused on revitalizing or protecting these rare plants. The results were compared to previous work from separate sites containing bunched arrowhead done by previous researchers in order to determine any commonalities among chemical features.
