Sonoran Desert Tortoise
An Agassiz's desert tortoise in a wind energy facility near Palm Springs, California. USGS scientists have been studying the ecology of tortoises at this industrial site since the mid-1990s to learn more about the effects of utility-scale renewable energy development and operation on these threatened tortoises.
