Explore a few tales of conservation triumphs that bring hope for wildlife.

Mom means a lot of different things in the world of wildlife.

An unusual set of twins is duplicating hope for Przewalski's horses.

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 (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.

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. 

The second-ever Przewalski's horse clone has arrived to his new home at the Safari Park.

SAN DIEGO (April 19, 2023) – Scientists are elated with the recent birth of the world’s second successfully cloned Przewalski’s horse, supporting the concept that cloning can be used as a viable tool for genetic rescue and contribute to new options for fostering resilience and genetic sustainability of endangered species. The foal, born Feb. 17, 2023 to a domestic surrogate mare, is a clone of a male Przewalski’s horse stallion whose living cell line was cryopreserved over 40 years ago in the San Diego Zoo Wildlife Alliance Biodiversity Bank’s Frozen Zoo^®.

SAN DIEGO (Jan. 27, 2023) – Conservationists at the nonprofit San Diego Zoo Wildlife Alliance have announced the birth of a Przewalski’s horse —a critically endangered species of wild horse that was categorized as Extinct in the Wild until 1996. The foal is the first Przewalski’s horse born at the San Diego Zoo Safari Park since 2014, and is one of only four individuals born in North America over the past year.
