Black-tailed prairie dog prey items. Grasslands inhabited by black-tailed prairie dogs support higher biodiversity than grasslands not occupied by them. Hundreds of species of vertebrates and invertebrates are associated with black-tailed prairie dog colonies. Vertebrate species richness on their colonies increases with colony size and density.
