【 摘 要 】

We describe the diversity of medium and large mammals from an area in the Colombian Orinoco River basin. For three years we systematically used camera traps at 72 sampling stations and walked forest and savanna transects to determine the diversity of medium and large mammals. Relative abundance was documented for 29 native and 2 feral mammals from a sampling effort of 1789 camera-days and 469.5 km walked. Thirty-one species of mammals (9 orders, 19 families) were recorded. Threatened species recorded included the giant armadillo (Priodontes maximus), lowland tapir (Tapirus terrestris), white-lipped peccary (Tayassu pecari), and giant anteater (Myrmecophaga tridactyla). The most abundant species were the collared peccary (Pecari tajacu) and the common opossum (Didelphis marsupialis). We recorded rare species, including the bush dog (Speothos venaticus) and the Llano semi-endemic long-nosed armadillo (Dasypus sabanicola). The species documented face diverse pressures, including development, hunting for subsistence, and competition with invasive species and livestock. Our results suggest that the surveyed areas are important for the conservation of mammals in the eastern plains of Colombia.
