Site description The Ruaha–Kilombero–Rufiji is the longest and largest river system in Tanzania, draining much of the southern highlands, southern areas of the central plateau and the coastal lowlands. The delta of the Rufiji river is the largest tidal mangrove wetland on the eastern coast of Africa. Mangroves cover an area of 54,500 ha within the delta, and are protected as the Mangrove-Rufiji Forest Reserves. Seven genera of mangrove occur, with Rhizophora, Avicennia and Heritiera dominant. There are several small settlements within the delta.
