Testudinidae Gopherus berlandieri Abstract We determined the diet of feral hogs (Sus scrofa; n = 197) in the semi-arid western zone of the South Texas Plains (STP) from stomachs of animals collected from autumn 1989 to autumn 1991 (n = 9 seasons). Vegetation made up approximately 93% of the annual diet by volume. Relative food composition and frequency of occurrence within the diet varied (P < 0.05) on a year and season basis. Diet overlap with large native herbivores was moderate and competition of hogs with these species may be restricted to times of resource scarcity. Animal matter constituted a small (6.7% annually) and seasonally variable part of the diet. A review of threatened and endangered plants and animals within the STP suggested minimal negative impact by direct consumption by feral hogs, though local and nonconsumptive effects could be substantial.
