Nyanganje Corridor: Elephant (during January-March) and buffalo still use the corridor annually to migrate between protected areas, although according to questionnaire respondents their numbers have reduced significantly in recent years. Other animals reported from the corridor include bushbuck, bushpig, leopard, lion, puku and yellow baboon.
Ruipa Corridor: Elephant (during March-May) and buffalo still use the corridor annually to migrate between Protected Areas, although according to questionnaire respondents their numbers have reduced significantly in recent years. Other animals reported from the corridor include the aardvark, Angolan black-and-white colobus, bushbuck, crested porcupine , Harvey’s duiker, bushbuck, hippopotamus, leopard, lion, puku, spotted hyaena, waterbuck and the Udzungwa-endemic Udzungwa red colobus.
Nyanganje Corridor: Amongst local farmers there is little perception of conflict with wildlife, apparently because elephants and other mammals cross farms rapidly at night without causing much damage to crops. However very few animals are still using the corridor, probably because of increased human activity – despite the narrow corridor being one of the less densely cultivated areas of the Kilombero Valley. The most immediate threat to the Corridor is the likelihood of intensified cultivation and human settlement until animals are completely unable to pass.
Ruipa Corridor: This Corridor is under immediate threat, especially in the Namwai forest area, from: rapid destruction of habitat by cutting of timber (including commercially) and burning; pole cutting and charcoaling; new human settlements and conversion of woodland to agriculture; hunting; increased cattle herding. An additional very recent threat is the settlement of Wasukuma immigrants along the western bank of the Kilombero River, with associated large herds of cattle and planting of crops.
