The African Eastern Arc Mountains, their biodiversity distribution and conservation priorities The Eastern Arc and coastal forests of Tanzania and Kenya are among the top 25 biodiversity hotspots recognized by Myers et al. (2000) Mt Kilimanjaro Taita Hills Mt Meru North Pare Mts The five Northern blocks of the Eastern Arc Mountains: South Pare Mts West Usambara Mts East Usambara Mts S Pare Mts Forests N Pare Mts The remaining forest fragments are clearly visible on satellite photographs Gaps with drier climatic conditions and svannah vegetation separate mountains supporting wet montane forest. Many forest species are unable to cross these gaps S Pare Mts Gap Gap N Gap Gap Pare Mts Gap The remaining forests of the Pare Mountains suffer from illegal logging activities Illegal mining and forest fires in the North Pare Mountains endanger the forests and their biodiversity Master student Obasanjo Mathew Nniwako (UDSM) is studying leaf litter arthropods of the Pare Mts. Very few species of staphylinid beetles are shared by the two blocks of the Pare Mts. Each of the two vicariant species of the genus Astenus is restricted to one mountain block Very few species cross the biogeographic boundary between the North and South Pare Mountains South Pare Mts Gap 1 the boundary Noth Pare Mts Gap 2 Gap 3 Gap 4 North Pare Mts Gap 1 Gap 2 Gap 3 Gaps within individual Pare Mountains blocks contribute to isolation among forests and cause geographic speciation South Pare Mts Medon Medon sp. 5 Medon sp. 4 Mt Kilimanjaro Taita Hills Mt Meru Conclusion 1: Both blocks of the Pare Mts suport locally endemic species and should be protected to avoid species extinction. West Usambara Mts East Usambara Mts South Pare Mts North Pare Mts Conclusion 2: Every remaining forest fragment suports locally endemic species and should be protected to avoid species extinction.
