Wetlands A wetland is an area of ground or soil that has a lot of water in it or is covered by a shallow layer of water. Two of the common types of marshes are freshwater and saltwater wetlands. The wetlands serve as homes for many unique groups of plants and animals.
Many birds use wetlands as resting grounds during migration.
These areas are also an important part of the Earth's biosphere. A wetland helps to prevent floods because it acts like a sponge. It also purifies the water supply in the surrounding area. This site is designed to take the student or teacher through the research process using the wetlands as a topic.
