Marshland is a type of wetland characterized by the presence of waterlogged soil and a variety of plant life, including grasses and reeds. These areas are often found near rivers, lakes, and coastal regions, where they play a crucial role in filtering water and providing habitat for wildlife. Marshlands are home to many species, including birds, amphibians, and fish, making them important ecosystems for biodiversity. They also help in flood control by absorbing excess water during heavy rains, which can protect surrounding areas from flooding.
