ABSTRACT
The Eastern Arc forests are situated on the chain of Precambrian block, faulted mountains (Griffiths 1993) - the Eastern Arc Mountains - that cut across Tanzania (Figure 2.1). The Arc comprises 11 separate mountain blocks, starting from the northeast: the Taita Hills in Kenya, the North and South Pare, East and West Usambara, Nguru, Ukaguru, Rubeho, Uluguru to the Udzungwa and Mahenge Mountains in the south (Figure 2.1).
