Abstract
The current study was conducted on the dry evergreen montane forest known as
Menagesha Suba State Forest, which is situated 30 km away in the south west of Addis Ababa
in Oromia National Regional State. 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.
