The study mainly focuses on the assessment of the diversity of herbaceous flowering plants in the Forest under study. Seventy five quadrats/plots of 20 m x 20 m (400 m2) were laid down along the transect line and the required vegetation data were collected and analyzed. A total of 128 species representing 102 genera and 44 families of herbaceous flowering plants were recorded from the Forest. Asteraceae is the highest in species diversity and richness (24%) followed by Poaceae (8.6%) and Apiaceae (4.7%) respectively. Of the 128 species of herbaceous flowering plants about 14 (11%) are endemic to Ethiopia of which four of them are threatened as vulnerable and endangered. Vegetation classification was done with PC-ORD computer software package which produced five plant communities.
