Abstract
The aim of this study was to investigate the Floristic Composition and Vegetation Structure of Bishoftu Massif forests ,Bishoftu, Central Shewa, Oromia Regional State, Ethiopia. Two transects were laid randomly in the sites, starting from the top massif to bottom valley, and spaced an average minimum of 200 m from each other. The two transects in each sites, had five quadrats each. In all transects line, the first sampling plot was located randomly, and the subsequent plots were established at 100-m intervals along the linear transect using GPS and compass. fifty sample quadrats with a size of 20 m * 20 m , 15 m * 15 m& 1m *1m for mature tree shrub& herb respectively, were laid down alternatively along the line transect. All tree, shrub, herb and grass species found within the quadrats in the sites were recorded. A total of 86 species were identified and documented from the study area, and the identified species belong to 37 families. Of the total species, trees constituted 19 (22.09%), shrubs 40 (46.51%), herbs 19 (22.09%), grasses 3 (3.49%) and climbers 4 (4.65%). In terms of species (sp.) number, family Fabaceae was the most diverse being represented by 19 spp., Lamiaceae and Asteraceae each represented by 11 and 7 spp., respectively, Poaceae represented by 4 sp., Anacardiaceae, Eurphorbiaceae and Oleaceae represented by 3 sp., Acanthaceae, Asclepiadaceae, Capparidaceae, Ebenaceae, Rubiaceae, Solanaceae and Tiliaceae each represented by 2 sp., where as all the remaining 22 Families were represented by 1 species. Mountains are places with a high degree of diversity and endemism. Biodiversity in such areas is necessary for our existence as well as valuable in its own right. Conservation and protectin of the study site and as well as the nearby biodiversity Mountain Massifs needs to be protected. Therefore, this study has improved to the understanding of the imperfectly known Bishoftu Massif forests.
