"Wetlands can be very large or very small and those along coastlines are just a few examples of types of the wetlands. Along with the freshwater, intermediate, brackish, and salt marshes of the coastal area, there are freshwater inland marshes, bottomland hardwood forests, edges of creeks, streams and ponds, and low elevation spots in fields that are considered to be wetlands. Lesser known wetlands may be the inland salt marshes of Utah and the Dakotas, the bogs in the northeastern and north-central United States, and the potholes of the northern Great Plains." (From the U.S. Geological Survey Wetlands)
