What type of water is in wetlands?

Depending on the geography of the wetlands, the type of waters present in a wetland can be either freshwater, brackish, or saltwater.

A wetland is a distinct ecosystem that is flooded by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils.
