"The Heat is On: Desert Tortoises and Survival" is a thirty minute television program exploring the world of the Mojave Desert Tortoise. It highlights the USGS research program on the Desert Tortoise and the role of that research in managing desert environments to allow the species to recover and escape the threat of extinction. The program was originally released on the internet in segmented form in 2010. This re-release presents the program in its entirety. The program was produced jointly by the USGS Western Ecological Research Center (www.werc.usgs.gov) in cooperation with the US Fish and Wildlife Service, Desert Tortoise Recovery Office.
