The primary difference between a marsh and a swamp lies in their dominant vegetation.12
- Marshes are wetland ecosystems characterized by mineral soils and plant life dominated by grasses, sedges, and reeds.2
- Swamps are wetland ecosystems also characterized by poorly drained mineral soils, but they are distinguished by plant life dominated by trees.1
Both environments typically feature poor drainage and waterlogged conditions, and they are often found in similar geographical settings, such as river floodplains, deltas, or low-lying depressions. While some regions, such as the Florida Everglades, may contain a unique combination of both marsh and swamp habitats, the fundamental classification remains dependent on whether the landscape is primarily defined by herbaceous vegetation or woody, tree-based growth.12
