Gopherus agassizii Testudinidae Precise and accurate estimates of desert tortoise (Gopherus agassizii) density are recognized as a critical component of both the Desert Tortoise (Mojave Population) Recovery Plan and the Washington County Habitat Conservation Plan. Distance sampling was utilized within the Upper Virgin River Recovery Unit, managed as the Red Cliffs Desert Reserve, to assess current population densities of desert tortoises. Intensive full-scale monitoring was completed within Management Zones 2, 3, and 5 of the Red Cliffs Desert Reserve from 1998 to 2001. The baseline density estimate of adult tortoises was 0.32 tortoises per hectare (95% CI: 0.29-0.36; CV: 5.85%) within Management Zone 3 and 0.29 tortoises per hectare (95% CI: 0.26-0.33; CV: 5.87%) throughout the Reserve.
