Floristic composition and vegetation structure of Ades forest, Oromia regional state, West Hararghe zone, Ethiopia

Abstract

This study was conducted at Ades forest in West Hararghe Zone, Ethiopia, for determining vegetations composition and structure. Systematic sampling method was used to collect vegetation data from 48 (20 m × 20 m) main sample plots for woody species that was established along a transect line. Sample plots were spaced at 10 m altitudinal drop from top to the bottom of the natural forest. Diameter at breast height and height of all woody species were measured. Species abundance, vernacular name and environmental variables were recorded in each sample plot. A total of 48 woody plants belonging to 42 genera and 29 families were recorded and identified. Fabaceae family had the highest number of taxa followed by Rosaceae and Flacourtiaceae families. Although the overall population structure of woody plants of the Forest revealed good regeneration status, the presence of anthropogenic disturbance in the area necessitates the need for conservation action in order to ensure sustainable utilization and management of the Forest.
