Woody species composition and structural analysis were investigated in Asasa forest which was once part of the Jibat forest. We used transect line to locate a sample plot of 20x20m from which vegetation data was collected. On each sample plot, height and diameter at breast height (DBH) of individual trees ≥5 cm and with height greater than 2 m were recorded. Seedlings and saplings of the woody species encountered in the subplots were recorded. Plant communities were identified using R-software. In addition structural and diversity analysis was conducted in the forest. We found that, a total of 115 woody plants species were recorded representing 47 families and 87 genera. Out of these plant species identified 59.13% species are trees, 33.03% are shrubs and 2.61% are lianas. From the total family the most dominant is Fabaceae with 13 species and 9 genera followed by Asteraceae and Rosaceae families with 6 species each and 1 genus and 4 genera respectively. Five plant community types were identified for our study forest. The forest is dominated by the lower diameter class indicating the dominance of newly growing plants due to the exploitation of the forest for construction. We recommend the need for appropriate forest management practices to sustainably use the resource base as it is detached from the continuous forest of Jibat.
