1.2.2.9 Wetland

Definition: Those ecosystems where the water table is at, near, or above the land surface for a significant part of most years and dominated by hydrophytic vegitation and biota. Wetlands include marshes, mudflats, swamps, wet meadows, and perched bogs. Wetlands also include seasonally flooded basins, playas, or potholes with no surface water outflow. Wetlands do not include shallow water areas with submerged aquatic vegitation falls (see Water Systems and Ocean Ecosystems). This does not include tidal, estuarian wetlands (see Estuarian Ecosystems).

This includes non-tidal fresh, brackish, and salt marshes, nonvegetated flats, and freshwater meadows, wet prairies, and open bogs.
