Frozen conservation is helping to secure the future for endangered species.
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.
SAN DIEGO (Sept. 27, 2022) – Kurt—the world’s first successfully cloned Przewalski’s horse—is thriving at his home at the San Diego Zoo Safari Park and learning the language of being a wild horse from Holly, a young female of his own species. Kurt and Holly’s pairing is a step in a long process to bring back lost genetic diversity to this endangered species.
DENVER — Black-footed ferret recovery efforts aimed at increased genetic diversity and disease resistance took a bold step forward Dec. 10, 2020, with the birth of “Elizabeth Ann,” created from the frozen cells of “Willa,” a black-footed ferret that lived more than 30 years ago.
On Aug. 6, 2020, the world’s first successfully cloned Przewalski’s horse was born in Texas at the veterinary facility of a ViaGen Equine collaborator, Timber Creek Veterinary. The foal, born to a domestic surrogate mother, is a clone of a male Przewalski’s horse whose DNA was cryopreserved 40 years ago at the San Diego Zoo Global (SDZG) Frozen Zoo®.
