Agroforestry has played an important role in increasing land productivity and enhancing livelihoods in developed and developing countries. The geographical location of Ethiopia covers wide agro-climatic zones and very significant biodiversity. This wide geographical condition of Ethiopia has created diverse and convenience environments for the survival and development of a variety of flora. There are about 6000 species of higher plant taxa in Ethiopia of which about 10% are endemic. The main objective of this study was to investigate diversity of woody species in different agroforestry systems of Sokoru District, Jimma Zone. The study was conducted from February to May, 2018. Frist the population density, tree height, diameter at breast height and basal area for each tree were calculated. Next Analysis of Variance (one-way ANOVA) of SPSS version 20 was used to determine the variation of woody species density among different agroforestry systems of the study area. Whereas descriptive statistics such as: tables and graphs were used to present the analyzed data. The results showed high diversity of woody species in home garden (2.79) followed by pastureland (2.77) and cropland (2.1). Moreover, the high similarity in woody species composition was found in home garden and cropland (65.7%). There should be awareness among the people regarding to the direct and indirect significance of woody species in the agroforestry systems of the study area.
