| description | This study investigated feeding preference and habitat association of waterbucks in Nechisar National Park from November 2016 to August 2017 by total count and direct observation methods. From this survey, 20 plant species were observed to be the food items consumed by waterbucks. Waterbucks were mostly grazers than browser. The plant species consumed by waterbucks was highly significant between seasons (χ2 = 121.34, df = 1, p<0.05). Out of 20 total plant species consumed, annual grass (11.5%), Leersia virginica (8.4%), and Cynodon dactylon (8.4%) were the most frequently consumed food items, but Tamarindus indica (2.9%), Balanites aegyptica (3.3%), and Acacia polycantha (2.36%) were the least consumed food items. There was significant difference between plant species consumed during both seasons (χ2 = 177.67, df = 19, p<0.05). The Shannon–Wiener diversity index result revealed that there were different varieties of food items for waterbucks in dry season (H’ = 2.9) than in wet season (H’ = 2.6). Young leaves comprised the largest proportion of plant parts consumed by waterbucks compared to others. There was a highly significant difference in feeding plant parts in both seasons (χ2 = 88.5, df = 7, p<0.05). Waterbucks spent more time on feeding in the morning and late afternoon during both seasons. The total number of waterbucks in each habitat varied due to food availability in different seasons. Different conservation measures should be taken against waterbuck reduction and create appropriate environment for waterbuck. |
