Celebrate a porcupine's journey of resilience and motherhood.

San Diego Zoo Wildlife Alliance is celebrating the birth of a Sumatran tiger cub at the San Diego Zoo Safari Park’s Tull Family Tiger Trail habitat. The cub was born August 23 to first-time mother Jillian. This birth is an important step in San Diego Zoo Wildlife Alliance’s ongoing work to conserve Sumatran tigers.  

Scientists have found the answer as to why mountain yellow-legged frogs are disappearing. 

It’s a familiar story: flames rage through Southern California landscapes. Do these burns benefit ecosystems, or do they damage habitats and reduce biodiversity?

San Diego Zoo Wildlife Alliance proudly shares first-look photos of the highly anticipated panda pair as they continue settling into their new home at the San Diego Zoo. Yun Chuan and Xin Bao, the first pandas to enter the United States in 21 years, arrived safely in San Diego on the afternoon of June 27. They are acclimating well to their new home in a private habitat and will not be viewable to the public for several weeks.

SAN DIEGO (May 17, 2024) – On the morning of April 12, 2024, the San Diego Zoo's Wildlife Care team was greeted with an exciting development.

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.

Technology is making a powerful difference in the world of conservation, and our teams are at the forefront.
