Abstract Sustainable farming practices have a potential for conserving biodiversity and also providing wood resources for local community in such it is a good solution to reduce deforestation and forest degradation. Different land uses encompass various types of biological diversity. This study was initiated to assess woody species diversity across different land use types in Dale Wabara district, West Oromia Region, Ethiopia. In three kebeles a total of 45 quadrates were laid on different land use types; 15 quadrates in each lowest administrative unit with three replications for each land use to get vegetation data by selecting households randomly. Plots size of 10 m × 10 m for woodlot, complete enumeration with about 900 m2 plot size for homegarden, 20 m x 25 m for coffee farm, 40 m x 40 m for grazing land and 50 m × 50 m for crop fields was drown. Species richness, diversity, evenness, frequency and important value index were analyzed between land use types. The study result showed that a total of 50 woody species belonging to 27 families were identified from these three kebeles. Fabaceae was the most dominant family with 7 and 14% species followed by Moraceae with 4 and 8% species. From the total identified species 78% were trees and 22% shrubs. The result of one-way ANOVA showed that the diversity of woody species significantly vary across land use types (F (4, 10) = 86.1, P< 0.001). The highest species diversity was recorded in homegarden (H’=2.796) followed by grazing land (H’=2.624). In general, agroforestry practices have a role for biodiversity conservation. Therefore, trees on farm land needs due attention to maintain woody species diversity within the system by farmers in order to more augment biodiversity conservation.
