What is the main characteristics of a swamp?

Swamps are wetland ecosystems characterized by saturated soil, standing water, and the presence of woody plants, such as trees and shrubs. They typically support diverse wildlife and play a crucial role in water filtration, flood control, and carbon storage. Swamps can be freshwater or saltwater and are often found in low-lying areas, along riverbanks, or adjacent to lakes. Their unique plant and animal communities are adapted to the wet, nutrient-rich environment.
