Palustrine wetlands include any inland wetland that contains ocean-derived salts in concentrations of less than 0.5 parts per thousand, and is non-tidal. The word palustrine comes from the Latin word palus or marsh. Wetlands within this category include inland marshes and swamps as well as bogs, fens, pocosins, tundra and floodplains. According to the Cowardin classification system Palustrine wetlands can also be considered the area on the side of a river or a lake, as long as they are covered by vegetation such as trees, shrubs, and emergent plants.
