Estuaries serve an important ecological role as they are transition zones between terrestrial and marine environments. They provide crucial habitat for diverse wildlife, including fish, birds, and various invertebrates. Estuaries act as nursery grounds for many species, supporting phases of their life cycles and enhancing biodiversity. Additionally, they function as natural water filters, improving water quality by trapping pollutants and sediments. Their unique ecosystems support high levels of productivity, making them vital for fisheries and human communities who depend on these rich resources.
