A study aiming at determining population status, feeding habits and conservation challenges ofrnTiang was conducted in Abobo district, Gambella National Park. The objectives of the studyrnwere to know the population structure, distribution and density of Tiang; the grass species eatenrnby Tiang; habitat preferences and to understand human-Tiang conflicts in the area. Line transectrncount was made to determine the population size, structure and distribution of Tiang in the studyrnarea. Feeding habits and habitat use observations were carried out on grazing herds. Feeding sitesrnwere classified into different habitat types based on the vegetation dominance of the area.rnQuadrats were marked in different feeding sites of Tiangs and the number and kinds of grassesrnwithin all quadrats were identified and counted; and identified in the Herbarium of Addis AbabarnUniversity. Data on conservation challenges of Tiang were collected by interviewing the localrnpeople and other stakeholders; and by observing the area. Data were statistically analyzed usingrnSPSS version 16 computer programme. The total population of Tiang was 26 and 93 during thernwet and dry seasons, respectively. The total population counted during the wet season wasrncomposed of 9 (34.6%) adult males, 10 (38.5%) adult females, 1 (3.8%) sub-adult male, 5rn(19.2%) sub-adult females and 1 (3.8%) young. Individuals counted during the dry season had 29rn(31.2%) adult males, 31 (33.3%) adult females, 9 (9.67%) sub-adult males, 15 (16.129%) subadultrnfemales and 9 (9.67%) young. The population density of Tiang was 0.2/km2 and 0.7/km2rnduring the wet and dry seasons, respectively. The distribution of Tiang was high at Pokede siternduring the wet season; and at Yawbela site during the dry season. Five food items were identifiedrnat three sites (Ubala, Yawbela and Pokede). There were significant variations in the proportion ofrnvarious food items of Tiang during the wet and dry seasons. The food items recorded were:rnThemeda triandra, Cyperus maculatum, Paspalum scrobiculatum, Digitaria macroble andrnCynodon dactylon. Threats on Tiang were the combination of habitat destruction (fromrncommercial agriculture), poaching and illegal activities. Tiang damage agricultural crops in thernarea. Human-Tiang conflict was observed. Regular census in order to have information on Tiangrnpopulation size is recommended.rnKey words: Tiang, population distribution, feeding habits, Human-Tiang conflicts.
