Freshwater Inland Marsh
A mineral wetland periodically submerged by standing water or runoff water from the surroundings. The freshwater inland marsh is a very productive ecosystem that is formed from the infilling of ponds and shallow lakes, often with the help of dam-building beavers. The soils of a marsh are fine, rich in organics and nutrients but very wet due to poor drainage and standing water. These wetlands are host to abundant wildlife and are important waterfowl breeding habitats offering abundant food and shelter.
