About the region
The Eastern Arc Mountains and Coastal_Forests of Tanzania and Kenya extend along the Tanzanian and Kenyan coasts and includes the islands of
Unguja and Pemba.
The region has two distinct habitats - the Eastern Arc Mountains and
Coastal Forests. Together they are home to 333 globally threatened
species including the Critically Endangered Aders' duiker (Cephalophus
adersi) and the Endangered Zanzibar or Kirk's red colobus (Procolobus
kirkii), which is found only in Zanzibar's Jozani Forest.
classified as a biodiversity hotspot itself, the region now lies within
two hotspots - the Eastern Afromontane Hotspot and the Coastal Forests of
Eastern Africa Hotspot - identified as part of a hotspots reappraisal
released in 2005.
A major threat to the Eastern Arc Mountains and Coastal Forests is
habitat fragmentation this means that many of the endemic and threatened species
are found in small sites.
The Coastal Forests are a mosaic of small scattered forest patches,
hence they are often referred to as the Coastal Forest Mosaic. The
Eastern Arc Mountains contain fragmented areas of forest and grassland,
with individual mountain blocks separated by drier and biologically
poorer habitats. This habitat fragmentation makes the threatened species
within key sites highly vulnerable to further habitat loss.
The greatest threats to these habitats are agricultural encroachment,
timber extraction and charcoal production, although weak management
capacity within government and communities is a serious issue.
