In the east, Mount Elgon has several vegetation zones. At lower altitudes there is montane forest with Olea hochstetteri and Pouteria adolfi-friedericii, which give way to Afrocarpus gracilior and olive forest at higher altitudes. Higher still, there is a zone of Afrocarpus and the bamboo Yushania alpina, and the summit moorland has tussock grasses, heaths, low herbs, giant lobelias and groundsels.
