Natural forests cover about on Kilimanjaro. In the foothill area maize, beans, sunflowers and, on the western side, wheat are cultivated. Remnants of the former savanna vegetation with Acacia, Combretum, Terminalia and Grewia also occur. Between and , coffee also appears as part of the Chagga home gardens agroforestry. Native vegetation at this altitude range (Strombosia, Newtonia, and Entandrophragma) is limited to inaccessible valleys and gorges and is completely different from vegetation at higher altitudes. On the southern slope montane forests first contain Ocotea usambarensis as well as ferns and epiphytes, farther up in cloud forests Podocarpus latifolius, Hagenia abyssinica and Erica excelsa grow as well as fog-dependent mosses. On the drier northern slopes olive, Croton-Calodendrum, Cassipourea, and Juniperus form forests in order of increasing altitude. Between and lie Erica bush and heathlands, followed by Helichrysum until . Neophytes have been observed, including Poa annua.
