Site description Mwea National Reserve contains gently rolling Acacia–Commiphora bushland on the north shore of the Kamburu Reservoir, at the confluence of the Tana and Thiba rivers, 100 km north-west of Nairobi. This small reserve lies just east of Masinga Reservoir (IBA KE032). Within its borders are 700 ha (including two small islands) of the 1,500 ha Kamburu Dam. The reserve was created in 1975 as a wildlife sanctuary, and is owned by the Mbeere County Council (pending District confirmation) and managed by the Kenya Wildlife Service. The area is semi-arid with an annual rainfall of between 250 and 500 mm. Thick bush (dominated by Acacia mellifera, with Grewia, Sesbania, Cassia and A. brevispica, as well as some Lantana) and scattered trees, including baobab Adansonia digitata, line the waterfront. This thins out further up the slope, with a mixture of A. mellifera and Commiphora species and some open glades. Richer scrub and woodland line seasonal rivers and streams. Sesbania forms a broad, fairly dense cover on flood-plains, especially the northern part of the Thiba. The reserve is essentially undeveloped. There is a campsite and c.95 km of rough roads, but no accommodation.
