The mountain bongo is found in dense mountain forests, and is threatened due to illegal hunting, logging, disease and loss of habitat, rendering them now critically endangered. They are only found in Kenya, in their natural habitat in the Aberdares Mountains, Mt. Kenya, Mau Forest, Cherengani and Ol Doinyo Eburu forests with only 108 left in the wild presently.They are classified critically enda,ngered species by the IUCN. The current population estimate (Mountain Bongo Surveillance Project 2015) for the Mountain Bongo is ca 100 individuals: Aberdare Mts (<50); Mt Kenya (10-15); Eburu Forest (ca 10); Maasai Mau Forest Complex (20+; new Bongo groups discovered May 2013); and SW Mau Forest (<10).
The decline of the mountain bongo has been caused by habitat loss and illegal hunting with dogs. Disease (such as rinderpest) caught from grazing cattle is also thought to have been a significant factor in their historic decline.
Mountain bongos are mostly grazers, feeding on leaves, vines, bark and occasionally grass. They need salt in their diet and regularly visit mineral licks.
