Why are wetlands considered important ecosystems?

Wetlands are vital ecosystems recognized for their ability to support high biodiversity and serve as effective natural water filters. These areas provide habitat for numerous species, including birds, amphibians, and aquatic organisms, thus contributing significantly to biological diversity. The dense plant life in wetlands plays a critical role in filtering pollutants from water, thereby improving water quality as it flows through these ecosystems. Additionally, wetlands help in flood control and storage by absorbing excess rainwater, which can mitigate the impact of flooding in nearby areas. The combination of these roles highlights the ecological importance of wetlands beyond any singular function.
