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) – For the third consecutive year, San Diego Zoo Wildlife Alliance will partner with the Tournament of Roses in Pasadena and participate in the 135th Rose Parade® presented by Honda on New Year’s Day. San Diego Zoo Wildlife Alliance’s parade float theme—“It Began with a Roar”—will feature a myriad of heartwarming stories from the San Diego Zoo that have inspired generations to care for and protect wildlife.

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

SAN DIEGO (Nov. 14, 2023) – San Diego Zoo Wildlife Alliance, in collaboration with Omaha’s Henry Doorly Zoo and Aquarium, reintroduced more than 70 endangered mountain yellow-legged frogs into a lake located in the San Bernardino Mountains. This release marks the first time the Southern California distinct population segment of the mountain yellow-legged frog has been reintroduced into a lake instead of a mountain stream. The frogs were bred at San Diego Zoo Wildlife Alliance’s Beckman Center for Conservation Research between 2020 and 2022, and then reared at Omaha’s Henry Doorly Zoo and Aquarium. The cross-country effort to save this California frog is part of a robust conservation breeding and reintroduction research program aimed at restoring populations of this declining species throughout its historic range.

In the quest to save a true Southwest icon, we've teamed up with the California Mountain Lion Project.

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

SAN DIEGO (Oct. 12, 2023) – Two critically endangered Sumatran tiger cubs emerged from their den today at the San Diego Zoo Safari Park. The cubs, born July 12, stepped out to explore their outdoor habitat, much to the delight of wildlife care staff and volunteers. 

SAN DIEGO (Oct. 11, 2023) – San Diego Zoo Wildlife Alliance has been recognized for its expertise in wildlife biobanking, and has partnered with the Species Survival Commission (SSC) of the world’s largest conservation organization—the International Union for Conservation of Nature (IUCN)—to form the new Center for Species Survival: Biodiversity Banking. The new center is the first ever to have a strategy focus rather than a taxonomic one.

Andean bear twins at the San Diego Zoo are a double dose of hope for this vulnerable species.
