issues include agricultural encroachment, illegal charcoal production and cutting trees for fire wood, building poles. Other uses including low income sources by villagers with farms close to the forest reserve to the issue of relocation. Some species found in the study area are known to be threatened or endangered and appear in the check-list of CITES species and in the Red list of endangered & threatened species (Table 9). Endangered wild species include plants that are directly overharvested in the wild for medicine, timber or forage plants. They also include populations used as sources of genetic variation for wild relatives of field crops and species which are crucial for the well-being of an ecosystem including dominant or keystone species and food plants of animals aof major concern (Frankel et al, 1995).

In conservation view two aspects are of importance that is endemism and number of species. Polhill (1968) realized the paucity of plant species endemism in the Jozani area. Jozani is ranked among the 25 high-priority sites for long-term conservation due to its importance for 46
the endangered red colobus monkey. The number of tourists visiting Jozani forest is rapidly increasing and thus an increasing forest income resulting into a revenue-sharing scheme among the surrounding villages. The forest also attracts local schools and it will in future form a centre for scientific research. Jozani-Chwaka Bay Proposed National Park possesses many near endemic species which have linkages with the Zanzibar-Inhambane regional centre of endemism. One of the arguments is the location of Zanzibar Island on a continental shelf close to the coastal mainland of Tanzania that lies in this phytochorion. The endemic and near endemic species are listed in Table 10 below.
