Boggy lowland is a type of wetland environment characterized by its soft, spongy ground and shallow water. It is often found in areas with poor drainage, such as near rivers or streams. The two most common types of boggy lowland are fens and marshes. Fens are wetlands that are fed by groundwater and have a high mineral content, while marshes are wetlands that are fed by surface water and have a high organic content. Both types of boggy lowland provide important habitats for a variety of wildlife.
