The primary feature of wetlands is their unique water-saturated ecosystems, which can be found in both freshwater and saltwater environments. Wetlands serve as transitional zones between terrestrial and aquatic ecosystems, characterized by the presence of hydric soils, water-loving plants, and a variety of wildlife. These ecosystems provide essential services such as water filtration, flood control, and habitat for numerous species. They also play a crucial role in maintaining biodiversity and supporting water quality.
