A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on characteristics that distinguish it as a distinct ecosystem. The water found in wetlands can be saltwater, freshwater, or brackish.
There are four major kinds of wetlands: swamps, marshes, bogs and fens.
A swamp is a wetland that is forested.

A bog is a wetland that accumulates peat, a deposit of dead plant material—often mosses, and in a majority of cases, Sphagnum moss.

A fen is one of the four main types of wetland, and is usually fed by mineral-rich surface water or groundwater.
Mangroves are various kinds of trees up to medium height and shrubs that grow in saline coastal sediment habitats in the tropics and subtropics – mainly between latitudes 25° N and 25° S
