Wetlands

Wetlands are the most bio diverse of all of the Earth's ecosystems. A wetland is an area where the soil is saturated with moisture, this saturation can be either permanent or seasonal. Wetlands are often covered completely or partially by shallow water. This shallow water often supports aquatic vegetation such as water lilies, cattails and other plants. Examples of wetlands include things such as swamps, marshes and bogs.
