Feed scarcity is a major challenge facing free-range beef farming in semi-arid areas. Specifically, low quality and quantity of forage in rangelands and higher feeding costs are the main constraints limiting smallholder free-range beef farmers’ participation in mainstream beef markets. Using farmers’ participatory approaches, this study identified major locally available forage resources (LAFRs) and evaluated their nutritional value. A total of 40 free-ranging commercially orientated smallholder beef farmers were interviewed using semi-structured questionnaires and tasked to identify LAFRs in the Cradock and Middelburg areas of the Eastern Cape, South Africa. Chemical analysis was conducted for the most cited forages such as African sheepbush ( Pentzia incana ), sweet thorn ( Vachellia karroo ) leaves and pods, reed ( Phragmites australis ), lucerne ( Medicago sativa ) hay, natural pasture grasses (NPGs) and barbary fig, or prickly pear cactus, ( Opuntia ficus-indica ) cladodes collected from twelve participants’ farms. Feed shortage was ranked by more than 53% respondents as the main constraint to smallholder beef production. Regardless of the farming area, crude protein content of  V. karroo  leaves and pods averaging 18.8 and 19.5%, respectively, was higher than other LAFRs. However,  V. karoo  pods had relatively low ash content than other forages in both farming areas.  Opuntia ficus-indica  attained high  in vitro  neutral detergent fibre digestibility at 12, 24 and 48 hr incubation periods, due to low neutral detergent fibre, acid detergent fibre and acid detergent lignin. Integration of participatory inventory and chemical analysis proved to be reliable in identifying LAFRs, with  V. karroo  leaves and  O. ficus-indica  cladodes being the main potential forage resources for inclusion in beef cattle diets. Further research is recommended to substantiate their supplementary nutritive value and level of inclusion in beef cattle finishing diets.
