description Kikori River Delta Overview
The Kikori River Delta lies on the Gulf of Papua in southern Papua New Guinea, where the Kikori River divides into tidal channels before reaching the sea. It contains extensive mangrove forests, mudflats, freshwater wetlands, and estuarine habitats, and its ecological character is shaped by large sediment flows, tides, and seasonal flooding; the delta supports fisheries and communities whose livelihoods depend on coastal and river environments.
