The river basin also contains other kinds of coastal swamp and freshwater swamp forest such as nipa palms forest, Bruguiera forest, mixed mangrove forest, Lumnitzera forest, Rhizophora forest, Melaleuca forest, and Avicennia forest. Another feature of Setiu Wetlands is the presence of seagrass beds.
The Wetlands is an area of high biodiversity and very hard to find. From a number of research carried out, 29 species of mammals, 161 species of birds, and 36 species of reptiles and amphibias are found. The Wetlands is also home to some endangered species such as river terrapin, Painted terrapin, and Green sea turtle.
