The National Fish and Wildlife Foundation is seeking proposals for research on the interaction between desert tortoises (Gopherus agassizii; tortoises) and common ravens (Corvus corax; ravens) in the Colorado and Mojave deserts in California at the Desert Tortoise Research Natural Area (DTRNA), the Superior-Cronese Desert Wildlife Management Area (DWMA), the Chuckwalla DWMA, and the Chemhuevi DWMA. Building upon work that was completed in 2013 involving the identification of raven nest locations, this request for proposals expands on that effort and includes the characterization of raven roost sites; it also includes a focused effort for the DTRNA to investigate the extent to which ravens are traveling to the area and feeding on tortoises.
NFWF is conducting this request for proposals in consultation with the Desert Managers Group (DMG) Raven Management Work Group and the Renewable Energy Action Team (REAT; California Department of Fish and Wildlife, California Energy Commission, Bureau of Land Management, and U.S. Fish and Wildlife Service), to implement a regional raven management plan to reduce predation by ravens on the desert tortoise in the California desert. Funding for implementation of the regional raven management plan is provided to and administered by NFWF as mitigation for impacts to the desert tortoise in the California desert.
