Abstract
The study was carried out to estimate diversity, distribution and abundance of avian species in Duguma Jaldeso Forest east Wollega Zone, Limu Woreda area covering wet and dry seasons from September 2015 to July 2016. Duguma Jaldeso forest is found 493 km a way from Addis Ababa. Forest, Bushland, Grassland and Farmland habitats were identified. Each vegetation type was used as sample site. Data were collected using point count and line transect method. The data were collected in the morning and afternoon. A total of 124 species of birds were identified during the whole study period. Out of the total, 48 species were observed during the wet season; 32 during dry and 44 species in both seasons. During the wet season, the highest species diversity was recorded in the forest habitat (H’=2.881) followed by the bushland (H’= 2.795). During the dry season, avian diversity was highest in bushland (H’=3.305) followed by forest (H’=3.267). During the wet season, high species similarity was seen between forest and bushland (SI=0.304 ) followed by grassland and farmland (SI= 0.27) and the lowest species similarity was observed between forest and farmland (SI= 0.1). Awareness creation to the local community to reduce human induced factors such as overgrazing, clear cutting and agricultural expansion within the area are recommended.
