A Forest Shaped by Floods
A forest floor disappears beneath muddy water. Tree trunks stand in the flood, and fish swim between them. Later, the water drains away, leaving damp soil and fallen leaves behind. In Congaree National Park, this changing landscape helps many kinds of living things find a home.
The park lies in central South Carolina, southeast of Columbia. Much of it protects a bottomland hardwood forest: a forest of broadleaf trees growing on low land near rivers. The Congaree River flows along the park’s southern edge, and smaller waterways cross the forest. When heavy rain swells the river and creeks, water can spread over the nearby floodplain, the flat land beside the waterways.
Flooding does not happen all the time, and the whole forest is not always underwater at once. Some areas are higher than others, so water reaches them less often. Low spots may hold water longer after a flood. These differences create a patchwork of wet and drier places where different plants and animals can live.
