In 2010, histological analysis of the feces of South African western giant elands was done in the Niokolo-Koba National Park and in the Bandia National Reserve. In both studies leaves, shoots of woody plants, and fruits were found to be the three major components. The other components that appeared in minor proportions were forbs and grasses, generally below five percent of the mean fecal volume. They were seen eating most foliage from "Boscia angusifolia", "Grewia bicolor", "Hymenocardia acida", and "Ziziphus mauritiana", and the fruits of "Acacia" and "Strychnos spinosa". In the Bandia Reserve, differences in diet were marked among age classes. The conclusions were that in the dry season the eland was a pure browser, consuming grasses in small amounts.
