Low marshland is an area of land that is typically wet and marshy, often found near rivers, streams, and other bodies of water. It is characterized by low-lying vegetation, such as grasses, sedges, and rushes, and is often home to a variety of wildlife. The term 'swale' is used to describe a shallow depression in the landscape that is filled with water, making it an ideal habitat for many species of birds, amphibians, and other animals. Low marshland is an important part of the natural environment, providing essential habitat for many species and helping to maintain the balance of nature.
