O'Farrell, T P; Kato, T

The objectives of this study were to (1) determine the distribution and relative abundance of blunt-nosed leopard lizards, Crotaphytus silus, on three sections of BLM land impacted by light to moderate petroleum developments; (2) correlate relative density estimates with absolute density estimates, characteristics of the dominant vegetation associations, density of animal burrows, percent open space, and level of oil field development; and (3) determine the radius of movement for the species. Relative densities of lizards in each section were measured by counting all lizards seen during four surveys conducted between May and July 1980.
