The study on population size and distribution was carried out in community forest in the Gasera district of Bale zone south east of Ethiopia from February 2017 to January 2018. Hamadryas baboon population size and distribution has never been studied and determined by Gasera district. Therefore, this study was conducted to assess Hmadryas baboon (Papio hamadryas hamadryas) Population Size and their Distribution in Community forest in Gasera District of Bale Zone, Southeast Ethiopia. Materials used for this study were GPS to plot study area, camera for scan sampling, Binocular to see a Hamadryas baboon from the distance, note pad, pen, pencil and was used to record data and video cameras was to insure hamadryas baboon counting. Assessing Population size and distribution of hamadryas baboon was estimated using the total count method at three counting sites by line transect. Data was analyzed by Chi-square test to compare sex and age structure of hamadryas baboon and T-test was used to compare wet and dry season population size of hamadryas baboon in each study site. The total number of individuals during wet season was 1199 and 1146 during the dry season. The average number of hamadryas baboon observed in the entire study area during both season was 1173. There was no significant difference between wet and dry season (x2=1.1978, df=1, p>0.05). During the wet season, the individual count from the study area was 16% adult male, 27% adult female, 12% sub adult male, 18% sub adult female, 10% juvenile male, 14% juvenile female, 3% infants. During the dry season, the individual count was 15.8% adult male, 28% adult female, 11.5% sub adult male, 18.5% sub adult female, 9% juvenile male, 14% juvenile female, 2.5% infants. The proportion of female hamdryas baboon was high in all age groups except infant in which identification of sex is difficult.
