A wide variety of wetlands have formed across the country due to regional and local differences in climate, geology, topography, hydrology, soils, vegetation, water chemistry, and other factors.
Although there are many different wetland types, they can be divided into two broad categories:
Non-Tidal Wetlands
Non-tidal wetlands account for most of the wetlands of the United States.
Tidal Wetlands
Tidal Wetlands are found along our nation's coasts within reach of the oceans' tides.
