There is increasing support for adopting landscape approaches to resource management, including monitoring threats that affect multiple resources across broad extents. However, there remains a need to assess potential threats to individual species of conservation concern. USGS is evaluating the extent to which a generalized indicator of terrestrial development can be used to inform and evaluate conservation actions seeking to protect habitat for the Mojave and Sonoran desert tortoise.

Energy Development and Changing Land Uses
Applied research and integrated regional assessments emphasize spatially explicit analyses of ecosystem components affected by energy development and land-use change in the western United States. Topics include sagebrush-steppe ecology; sagebrush habitat assessments; the effets of human activities (including energy development, transportation, and recreation) on habitats and wildlife behavior... - Publications

Connectivity of Mojave Desert tortoise populations—Management implications for maintaining a viable recovery network
Executive SummaryThe historic distribution of Mojave desert tortoises (Gopherus agassizii) was relatively continuous across the range, and the importance of tortoise habitat outside of designated tortoise conservation areas (TCAs) to recovery has long been recognized for its contributions to supporting gene flow between TCAs and to minimizing impacts and edge effects within TCAs. However, connectiQuantifying development to inform management of Mojave and Sonoran desert tortoise habitat in the American southwest
Two tortoise species native to the American southwest have experienced significant habitat loss from development and are vulnerable to ongoing threats associated with continued development. Mojave desert tortoises Gopherus agassizii are listed as threatened under the US Endangered Species Act, and Sonoran desert tortoises G. morafkai are protected in Arizona (USA) and Mexico. Substantial habitat f
