This paper presents information obtained from 1972 and 1973 on the reproduction, survival and density of snowshoe hares (Lepus americanus) in Cache National Forest, Utah. The main objectives of the study were: (1) to estimate population densities; (2) to measure adult and juvenile mortality ; and (3) to measure natality rates , including recruitment (realized annual natality).

Live-trapping and snaring were used to estimate population levels and to collect hares for necropsy. Fecal pellet counts were used to evaluate relative habitat use by hares.

The results of this study were compared to other studies of snowshoe hare ecology in North America. Based on the density, survival and reproductive output observed, recommendations were made for the management of snowshoe hares in Utah.
