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

ii) Endemic and near endemic species<br />
Endemism describes species that are native to a particular geographic area or continent. In<br />
conservation view two aspects are <strong>of</strong> importance that is endemism and number <strong>of</strong> species.<br />
Polhill (1968) realized the paucity <strong>of</strong> plant species endemism in the <strong>Jozani</strong> area. <strong>Jozani</strong> is<br />
ranked among the 25 high-priority sites for long-term conservation due to its importance for<br />
