The forest vegetation of the Harenna Escarpment (Bale Province, Ethiopia) - syntaxonomy and phytogeographical affinities
Bussmann, Rainer W.
A phytosociological study was carried out in the large forests of the Harenna Escarpment, southern Ethiopia. The analysis of 42 relevés revealed that the forest vegetation of this region belongs to 7 distinct associations with 3 subassociations of 4 alliances, belonging to 4 orders of 4 classes. Of these units the Podocarpo falcati-Coffeetum arabicae (with the subassociations filicetosum decipientis and typicum), the Ocoteo kenyensis-Oleetum welwitschii, Erythrino brucei-Croteonetum macrostachyus, Cassipoureo malosanae-Scheffleretum abyssinicae, Hagenio abyssinicae-Dombeyetum torridae and the ericetosum excelsae of the Hypericetum revoluti Bussmann 1994 are newly described. Phytogeographically the submontane forests of Harenna are closest related to the forest vegetation of the northern Kenyan mountains, whereas the montane and subalpine forests show clear similarities to Mount Kenya and Kilimanjaro.
