The 15.8-acre Blackwell Heritage Preserve is located within an intricate network of springs and small streams that drain hilly topography bordering the narrow floodplain of the Enoree River. The streams are well-channeled with some flow throughout the year. Although they eventually merge with the floodplain of the Enoree, these streams are spring-fed and not dependent upon seasonal flooding of the river. This produces constant groundwater seepage and extensive saturated soil conditions, which are quite rare in the Upstate and are classified as Piedmont seepage forests. As the name implies, the vegetation is dominated by hydrophytic tree species that include red maple, swamp tupelo, gum, American elm and pumpkin ash. Increased development around the preserve increases runoff which sometimes scours the seepage sites. The seepages and streams provide habitat for the federally-endangered plant species, bunched arrowhead. Approximately 75 percent of the preserve is wetlands and over 10 acres are accessible only by wading the Enoree River. The small portion of land not in wetlands is dominated by Virginia pine. Pink lady slipper orchids can be observed in the pine areas. A portion of the preserve was acquired via wetlands mitigation by the SC Department of Transportation.
