    ABSTRACT: The study was conducted on Berbere Forest in Bale Zone of Oromia Regional State, south east of Ethiopia with the objective of determining the structural analysis and natural regeneration status of the forest. Systematic sampling method was used to collect vegetation data. Seventy two nest quadrat sizes of 400 m2 (20 m × 20 m) for trees and shrubs were used. Within the main quadrat, two opposite side of each sub-quadrat of 25 m2 (5 m × 5 m) for sapling, 4 m2 (2 m × 2 m) for seedling of woody plants. The diameter and height were measured for all individual trees and shrubs having DBH (Diameter at Breast Height) ≥ 10 cm thick and ≥2 m height by using a diameter tape or caliper and clinometer respectively. For description and analysis of vegetation structure Diameter at Breast Height (DBH), basal area, tree density, height, frequency and important value index were used. Structural analysis of some selected tree species was revealed four different population patterns (bell shaped, inverted J-shaped, irregular and U-shaped). The total basal area of Berbere forest was 87.49 m2/ha, but most of the basal area was contributed by few large sized Moraceae family (Ficus vasta, Ficus ovate and Ficus thonningii) plant species. Analysis of regeneration status of woody plants in the forest showed 37.09% trees/shrubs species exhibited “good”, 19.35% showed “fair”, 6.45% showed “poor” and 25.81% trees/shrubs species were “not regenerating” at all and 11.29% trees/shrubs species were available only in sapling or seedling stage. Studies on the structure and regeneration of the forest indicated that there are species that require urgent conservation measures. Therefore, based on the results of this study, we recommended detail regenerating studies of seed bank in relation to various environmental factors such as soil type and properties.
