Abstract

This research focused on the floristic description and forest condition assessment comparisons of Achera Forest in Northwest Ethiopia. The floristic data were recorded from 20 x 20 m 30 sampling plots. Diameter at breast height, height and number of each species individuals were recorded from all plots. A total of 48 woody species, representing 41 genera and 25 families were recorded. The Fabaceae family was the richest (7 species) followed by Combretaceae (5 species) and Asclepiadaceae (4 species). Life-form composition was 60.87% trees, 9.57% shrubs, 17.37% tree/shrubs and 2.17% woody climbers. The overall Shannon diversity index H′ = 3.37 was high for the richness and evenness of the woody species. The low basal area (3.61 m2/ha) and population structure revealed the need for conservation measures for species with poor regeneration status. The floristic diversity revealed that the forest was a Combretum-Terminalia woodland type. There was a density decline in the higher diameter class suggesting the existence of disturbance and unsustainable exploitation of the forest. Based on the results of the study, comprehensive studies and sound management system are recommended.
