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.

LA JOLLA, Calif. (Feb. 26, 2024) – Love is in the water for the critically endangered Sunflower Sea Star as a team in California successfully spawned and cross-fertilized gametes from a male and a female, resulting in fertile eggs. This success marks another incredible step forward in an ongoing collaborative effort to save the species from extinction. This advancement took place at Birch Aquarium at Scripps Institution of Oceanography at UC San Diego, where their experts were joined by partners from the Aquarium of the Pacific, California Academy of Sciences, San Diego Zoo Wildlife Alliance (SDZWA) and Sunflower Star Laboratory. 

SAN DIEGO (Feb. 22, 2024) – San Diego Zoo Wildlife Alliance (SDZWA) took an important step forward in having giant pandas return to the San Diego Zoo by signing a cooperative agreement with China Wildlife Conservation Association and filing a permit application with the U.S. Fish and Wildlife Service.

SAN DIEGO (Feb. 14, 2024) – It's a match! In the world of conservation, pairing a perfect couple is more than just a romantic endeavor; it could be the key to saving an endangered species. San Diego Zoo Wildlife Alliance (SDZWA) is playing Cupid for the critically endangered ‘alalā, a unique bird found only in Hawai‘i. In a new, unconventional study recently published in the journal Animal Conservation, SDZWA scientists hoping to hone their matchmaking skills applied personality traits to these crow relatives to find love connections to result in successfully fertilized eggs.

SAN DIEGO (Jan. 30, 2024) – San Diego Zoo Wildlife Alliance and San Diego State University (SDSU) are joining forces to usher in a new way of studying snakes. In a collaboration between San Diego Zoo Wildlife Alliance and Rulon Clark, Ph.D., professor of biology at SDSU, biologists are tagging wild rattlesnakes with external transmitters and accelerometers. Previously, telemetry devices on snakes had to be surgically implanted—severely limiting this area of study. San Diego Zoo Wildlife Alliance and SDSU are among the first to use acceleration technology to study snakes.

Understanding the effects of gold mining is crucial to protecting wildlife in the Peruvian Amazon.

SAN DIEGO (Jan. 9, 2024) – To apply cutting-edge technology to the conservation of koalas, San Diego Wildlife Alliance is partnering with Illumina, a leading genomic sequencing technology company, through the Illumina iConserve program to sequence the whole genomes (an individual’s complete set of DNA) of nearly 100 koalas residing in North America over the past 30 years. Whole genome sequencing is integral to learning more about Koala Retrovirus, KoRV – a virus that can insert into the koala genome and is associated with various health issues in koalas including immunosuppression and cancer.
