Wetland is an area of land that is covered or soaked with water for all or part of the year. The ground can be muddy, and water may be still or slowly moving. Wetlands include different types of environments such as marshes, swamps, and coastal areas. They often have plants that grow well in wet conditions.

Wetlands are found worldwide, both inland and along coastlines. They exist as part of natural water systems over time. Wetlands support a wide variety of plants, animals, and birds. Many species depend on these areas for food and shelter.
