Wetlands are important for biodiversity because they provide a unique habitat for a wide variety of plant and animal species. They support a diverse range of species due to their high levels of productivity and the presence of various habitats within wetlands such as marshes, swamps, and bogs. Wetlands also act as breeding grounds, feeding areas, and shelter for many species, contributing to overall biodiversity and ecosystem health. Additionally, wetlands help regulate water flow, filter pollutants, and provide essential services that support the surrounding ecosystems.
