Classification. Other classification systems exist however. Cowardin (1979) recognizes the following five major wetland classifications: marine, estuarine, lacustrine, riverine, and palustrine. Marine and estuarine wetlands are associated with the ocean and include coastal wetlands, such as tidal marshes.

Palustrine wetlands may be isolated or connected wet areas and include marshes, swamps, and bogs.
