What Is the Wetlands Biome Like?


Quick Answer

Wetlands biomes are large areas saturated by water such as marshes, swamps and bogs. Wetlands are home to a wide variety of aquatic vegetation uniquely adapted to thrive in hydric soil. Wetlands play a number of important environmental roles including water purification, shoreline stability and flood control. Wetlands are considered to be the most biologically diverse of all ecosystems.

Wetlands provide a boundary between dry land and large bodies of water. Wetlands tend to be dominated by either aquatic, marsh or swamp vegetation depending on the frequency and severity of flooding they experience. Categorizing wetlands as either riverine, lacustrine or palustrine depends on their hydrology. Carbon is the prime nutrient cycled throughout wetlands, although large quantities of nitrogen, sulfur and phosphorus are typically found within wetland soils.

Many different species of amphibians, reptiles, birds and mammals make their home in wetland environments. Many fish species rely heavily on wetland environments, and an estimated 75 percent of U.S. commercial fish stocks depend on estuaries for their survival. Insects and invertebrates make up more than half the known species found in wetland biomes. Temperatures and climates vary depending on where wetlands are located, although many wetlands can be found in temperate zones.
