Jozani - Chwaka Bay Conversation Area is a natural protected forest reserve covering about 30km² about 23 miles South of Zanzibar Town. The coral rag zone is habitat for wildlife species of national and international significance including the endemic and near extinct Zanzibar leopard (P.pardus adersii), the red colobus monkey (Procolubus badius Kirkii) and the Ader duiker (Cephalophud adersii). Jozani forest is the only area where these particular species could be preserved in-situ. The forest also harbours the five important vegetation types spread over the small area not exceeding 30km² i.e. the ground water forest: the coral rag forest ; salt marsh; mangrove forest; and sea grass beds.
The present and past modifications by men include: - a small area on the ground water forest planted with Callophyllum inophyllum - considered to be indigenous and some exotics such as Casuarina equisetifolia and Eucalypts and nature trails constructed for ecotourism activities in the ground water forest and in mangrove.
