[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.
Khat from Chyulu hills is known as Chuylu, as opposed to Miraa, which is cultivated in the Meru County.
[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.
