What are wetlands? Why are they important?
Wetlands are the most productive ecosystems on earth. They are areas saturated by surface or groundwater that support hydric, or water-loving, vegetation. They filter and remove harmful pollutants and contaminants from water, which makes cleaner water in lakes and rivers. Wetlands moderate flooding, prevent soil erosion, and recharge groundwater. They also provide local wildlife with shelter, food and breeding grounds.
