Mammal abundance indices in the northern portion of the Great Basin, 1962-1993

Indices of abundance of selected mammals were obtained for two study areas within the Great Basin: the Idaho National Engineering and Environmental Laboratory, Idaho, and Curlew Valley, Utah, USA. Data collection occurred biannually 1962-1993, with varying durations among species and sites. Abundance indices were obtained for coyotes (Canis latrans), lagomorphs (primarily black-tailed jackrabbits, Lepus californicus), and eight species of rodents. Data were originally gathered as part of a long-term study of interactions among predator and prey populations, concentrating on aspects related to coyotes and black-tailed jackrabbits. Secondarily, these data are useful in portraying trends in mammal abundance on these two Great Basin sites.
