SAN DIEGO (Dec. 6, 2023) – The Endangered Species Act turns 50 years old this year. A new report released by the Endangered Species Coalition, Ten Stories of Hope: The Endangered Species Act at 50, highlights 10 case studies of conservationists using different strategies to protect and recover imperiled fish, birds, plants and mammals in the United States. Ninety-nine percent of species protected under the Endangered Species Act have been saved from extinction, including the humpback whale, grizzly bear and bald eagle. The Top Ten report features the Stephens’ kangaroo rat and the efforts of San Diego Zoo Wildlife Alliance to help recover the species using conservation translocation.

SAN DIEGO (Nov. 30, 2023) – Scientists at San Diego Zoo Wildlife Alliance have achieved a major milestone in saving wildlife species: With a blue-eyed black lemur’s cells recently added to its Wildlife Biodiversity Bank’s Frozen Zoo®, the nonprofit conservation organization’s unique collection of genetic material now contains 11,00o individual cell lines from more than 1,250 species and subspecies—some critically endangered. No other biobank in the world has a comparable number of living cell lines, with the potential to reverse losses of genetic diversity and contribute to population sustainability for  endangered and threatened wildlife species.

SAN DIEGO (Nov. 27, 2023) – When a mysterious illness called “sea star wasting syndrome” decimated 95% of the sunflower sea star population, and some 20 other sea star species along the Pacific Coast from Baja to Alaska in 2013, scientists rallied to understand the factors that caused such a massive wasting event. Now as part of the greater recovery initiative, in a scientific first, dozens of baby sunflower sea stars were hatched and are thriving thanks to a breakthrough in reproductive cell cryopreservation technology.

Artificial intelligence and machine learning are changing the game for wildlife research and conservation.

SAN DIEGO (Nov. 9, 2023) – A binational team of scientists, using creativity and innovation, adorned dozens of endangered thick-billed parrots with tiny solar-powered satellite transmitters to track and reveal their winter migratory nesting sites in the remote treetops of the Sierra Madre Occidental ranges. Their research reveals new critical habitat, 80% of which has no formal protection.

Biodiversity banking is a critical component of conservation, and the need for it is more urgent than ever. 

SAN DIEGO (Sept. 7, 2023) – The world’s second successfully cloned Przewalski’s horse is thriving at his home at the San Diego Zoo Safari Park. The foal, born Feb. 17, 2023, and his surrogate mother, a domestic quarter horse, were recently moved from his birthplace at ViaGen Pets & Equine cloning facility in Texas so he can learn the language of being a wild horse from his own species.
