[citation needed] The Chyulu Hills are located about 150 km east of the Kenya Rift.

[4] Lower parts of the hills are composed of grassland and thicket, while above roughly 1800 metres is dominated by montane forest.

[3] Mammals found in the hills include eastern black rhinos,[5] Cape buffaloes, bushbucks, elands, elephants, bushpigs, Masai giraffe, leopards, lions, mountain reedbucks, steinbok, wildebeest and Grant's zebras.

Various snakes inhabit the hills, like black mamba, puff adder and rock python.

[2] The western flank of the hills is covered by the West Chyulu Game Conservation owned by Maasai group ranches.

[3] Potential threats to the ecosystem include poaching, overgrazing by growing population of Maasai herders and scarcity of water.
