Types of Wetlands

Wetlands are as unique as the place they form. There are a wide variety of wetlands due to regional and local differences in things like climate, geology, topography, soils, vegetation, water chemistry, and other factors.

Although there are many different wetland types, they can be divided into two broad categories: tidal wetlands and non-tidal wetlands.
