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.

These conservation canines have what it takes to locate endangered mountain yellow-legged frogs.

Scent detection dogs sniff out frogs that would otherwise be impossible for us to find.

SAN DIEGO (Oct. 3, 2022) – For more than two decades, conservationists from San Diego Wildlife Alliance have been waiting with anticipation as they watched for the slightest signs of breeding from a rare reptile species. This summer, their patience paid off after wildlife care team members at the San Diego Zoo welcomed 41 tiny Indian narrow-headed softshell turtle hatchlings—becoming the first accredited conservation organization in North America to hatch these endangered turtles, and furthering the organization’s ongoing work to save this vital Asian species.

SAN DIEGO (May 25, 2022) – A new study from scientists at San Diego Zoo Wildlife Alliance (SDZWA), published today in the Journal of Applied Ecology, found endangered mountain yellow-legged frogs being reared for release into the wild have a greater chance of survival if introduced to artificial currents at early stages of their development. While the findings support a growing body of evidence that suggests raising bred animals in an environment similar to where they will be released can boost survival rates, the study goes even further, showing the timing of experiential exposure may be critical to successful species recovery translocations.
