This study examines the major ion distribution in the ground and surface waters at Ochlawaha bog in western North Carolina, in relation to the distribution of the endangered plant species Bunched Arrowhead (Sagittaria fasciculata) within the bog. Bunched Arrowhead is a small flowering plant that is only found in southern Appalachian mountain bogs, specifically Henderson County, NC and Greenville County, SC. A restoration project was undertaken at Ochlawaha bog to expand the suitable habitat for the Bunched Arrowhead. Since the restoration, the plants have spread in only a couple specific locations within the bog. This study was conducted to determine if water chemistry may play a role in determining bunched arrowhead distribution. Water samples were collected over the past two years, and ion concentrations were determined using ion chromatography. The data were compiled and compared to other bunched arrowhead sites in North Carolina and South Carolina. The data from Ochlawaha bog showed that there was not much difference in the major ion distribution within the bog, which is consistent with published results at other sites. Major-ion chemistry at both Ochlawaha bog and the sites previously studied in South Carolina is dominated by calcium and sodium cations and bicarbonate anions.
