Wetlands Wetlands are areas of land that are usually characterized by poor drainage and the presence, most or all of the time, of slow moving or standing water saturating the soil.
Wetlands support plants that are adapted for life in saturated soil.
Most wetlands consist of either mosses, grasses or certain types of trees. They are usually classified, according to the soil and plant life found there, as bog, marsh, or swamp. Bogs tend to have more mosses and other specialized plants than grasses or trees and also have spongy peat soils. Their soil is made up almost entirely of organic matter with few minerals. Animal life is uncommon on bogs.
