It’s a familiar story: flames rage through Southern California landscapes. Do these burns benefit ecosystems, or do they damage habitats and reduce biodiversity?
Helping Mojave Desert Tortoises Survive in a Rapidly Changing World
SAN DIEGO, PALM DESERT, Calif. (April 15, 2024) – Seventy critically endangered Mojave desert tortoises have successfully emerged from their winter burrows after being reintroduced into their native habitat on Edwards Air Force Base in Southern California. San Diego Zoo Wildlife Alliance and The Living Desert Zoo and Gardens, the global authority on desert plant and wildlife conservation, are working in partnership with Edwards Air Force Base, the U.S. Fish and Wildlife Service and the U.S. Geological Survey, using headstarting techniques designed to increase the survival rate for young tortoises. The cohort of young tortoises was the first in the program to be reintroduced into the wild after receiving a combination of an indoor- and outdoor-rearing. Within 24 hours of reentering their native habitat, the tortoises were exhibiting positive natural behaviors by constructing new burrows or modifying existing burrows for shelter. Now, six months later, they have emerged after winter brumation—a state of deep sleep specific to reptiles—and are spending more time basking at burrow entrances. Scientists are currently conducting health assessments and replacing radio transmitters on the tortoises to continue monitoring their success and better understand the juvenile age class.
SAN DIEGO and PALM DESERT, CALIF. (Sept. 30, 2022) – As a changing climate impacts wildlife around the globe, one keystone species in the Southwest United States serves as a prime example of the dangers of rising temperatures and habitat loss.

The plight of a desert icon and our efforts to turn things around.
San Diego Zoo Global conservationists reared young desert tortoises for one to two years before the planned release—a strategy referred to as “headstarting,” which provides a safe environment during their most vulnerable period, before translocating to the native habitat.
