Imagine a World Where All Life Thrives.

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.  

Sumatran tiger cubs Puteri and Hutan are much more than cute faces.

Helping Mojave Desert Tortoises Survive in a Rapidly Changing World

When it comes to pollinators, most people think of bees, butterflies, and birds, gracefully flitting from flower to flower. But do you think about bats, mice, lemurs, and mongooses?

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 (July 27, 2023) – San Diego Zoo Wildlife Alliance is celebrating the birth of two Sumatran tiger cubs—the first of this critically endangered species to be born at the San Diego Zoo Safari Park’s Tull Family Tiger Trail habitat in seven years. Their birth also comes just in time for Global Tiger Day. With only an estimated 400 to 600 Sumatran tigers remaining on Earth, the births are significant in increasing the worldwide population of this tiger species and furthering the nonprofit conservation organization’s ongoing work to conserve them.

For the people and jaguars who share space in the Peruvian Amazon, finding ways to coexist is key.
