ABSTRACT: The abundance of uncultivated pasture species in the semi-arid zone of Aliero LGA of Kebbi State was investigated. The encountered pasture species comprises of; D. alata, A. gayanus, C. banghalensis, B. radiate, C. biflorus, P. pedicellatum, S. sphacellata and I. hirsute. The results showed that the pasture species varies in their frequencies and yields with the highest dominant and dried matter weight species from D. alata and B. radiate having 21.43% each and I. hirsute and B. radiate having 3.73kg each respectively while the least frequent and dry matter yield species are S. sphacellata and C. biflorus having 2.38% each and A. gayanus having 0.45kg respectively. These pasture species are the dominant in the study area during the 2018 rainy season. The study area constitutes grasses, legumes and forbs species which are of good pasture materials that could support ruminant production. Also the area comprises of decreaser and increaser pasture species which support the youths for their livelihood during the rainy season.
