The Congaree Bluffs Heritage Preserve comprises 201 acres and contains steep bluffs bordering the Congaree River and offers a birds-eye view of Congaree National Park. Located in Calhoun County, the preserve harbors significant stands of American beech, oak-hickory, and bottomland hardwood forest. No comparable sites exist in the coastal plain of South Carolina. There are several other sites nearby on private lands, but these areas, along with the preserve, are unique. Similar systems in and around the Florida Panhandle have been documented to have the greatest number of trees per unit area within the temperate forest of the eastern United States. More than 100 species of trees, shrubs, and woody vines exist in the preserve from the ridge base to the crest of the bluffs. Woody plants may number 200 species.
