dc.description.abstract	The study was conducted in Robit Bata Church Forest, northwestern Ethiopia to investigate the floristic composition, population structure and regeneration status of woody species. Systematic random sampling method was employed to collect the vegetation data at every 30 m interval between sample plots and 50m apart between each line transects. To collect data on seedlings and saplings in each main plot, five subplots of 5m x 5m (25m2) size were located at the four corners and one at the Centre of the main plot was used. A total of 24 plots, measuring 20m x 20m, were sampled along line transects following the altitudinal gradient. In each plot, all woody species were identified, counted, and height and diameter at breast height (DBH) were measured and recorded. A total of 42 species of plants belonging to 41 genera and 28 families were recorded in the study area. Out of these plant species, 32 (76.2%) were trees, 4 (9.5%) tree/shrub, 6 (14.3%) shrubs. Fabaceae was the dominant family represented by 9 species (11.84%) followed by Euphorbiaceae 4 species (9.5%), Asteraceae 3 species (7.1%) and Myrtaceae 2(4.8%). The remaining 24 families represented by 1 species each (2.4%). The diversity and evenness of woody species in Robit Bata Church forest were 2.98 and 0.79, respectively. The total density and basal area of woody species in Robit Bata Church forest were 659.38 individuals per hectare and 5.8 hectare, respectively. The results on DBH class were inverted J shaped, J-shaped and irregular pattern distribution and important value index (IVI) suggest that species with poor reproduction and recruitment status as well as low IVI values need to be prioritized for conservation activities. The study area showed that fair regeneration status of the species while some of them had not seedling and sapling which indicated poor or none regeneration status of the species in the church forest. The community has critically affected species of the woody plants and population structure of the forest as evidenced by the very low density of many species. Cutting of shrubs or medium size trees were replaced by planting of coffee for income, natural disaster (wind) and construction of new church are the major problems that could pose serious threat to the forest resources. Therefore, to address these problems and enhance the sustainable utilization of the forest resources, realistic and viable solutions have to be explored and urgently implemented.
