San Diego, California - The Dvur Kralove Zoo in the Czech Republic has announced that an elderly northern white rhinoceros, Nabiré, has passed away. The female rhino was born in 1983 and died July 27, 2015 from complications with a pathological cyst. Her death leaves only four northern white rhinos remaining in the world: an elderly female at the San Diego Zoo Safari Park, named Nola; and three under human care at the Ol Pejeta Conservancy in the African nation of Kenya: a male, Sudan; and two females, Najin and Fatu.

“Our condolences go out to the Dvur Kralove Zoo for this particularly difficult loss,” said Randy Rieches, curator of mammals for the San Diego Zoo Safari Park. “Watching this wonderful subspecies move one step closer to extinction breaks the hearts of all of us who have worked with and love rhinos.”

Northern white rhinos are at the brink of extinction because of poaching in Africa. Only a few have lived in zoological settings, and those animals have been largely non-reproductive.

San Diego Zoo Global is working to save the genome of this rhino subspecies through the collection of genetic material. Samples of 12 northern white rhinos are currently preserved in the Frozen Zoo® at the San Diego Zoo Global Institute for Conservation Research.

San Diego Zoo Global just received a $100,000 grant from the Ellen Browning Scripps Foundation to continue this research and rescue effort.

“After hearing about the plight of the northern white rhino, I shared San Diego Zoo Global’s plan for a genetic rescue of the species with the Scripps family,” said Doug Dawson, executive director of the Ellen Browning Scripps Foundation.  “Instantly, we unanimously and enthusiastically agreed this is where we wanted to commit Miss Ellen’s philanthropic investment this year!”

In addition to the genomic research at the Institute for Conservation Research, a rhino rescue facility is being built at the San Diego Zoo Safari Park to house a colony of white rhinos, to ensure the preservation of the species.

In the wild, rhinos are killed for their horns a unique physiological feature made up of keratin, the same material that forms human hair and fingernails. Many cultures erroneously believe the rhino horn has medicinal value, so sadly, the illegal market in horns taken from poached animals continues to thrive.

Bringing species back from the brink of extinction is the mission of San Diego Zoo Global. As a leader in conservation, the work of San Diego Zoo Global includes on-site wildlife conservation efforts (representing both plants and animals) at the San Diego Zoo, San Diego Zoo Safari Park, and San Diego Zoo Institute for Conservation Research, as well as international field programs on six continents. The work of these entities is made accessible to children through the San Diego Zoo Kids network, reaching out through the Internet and in children’s hospitals nationwide. The work of San Diego Zoo Global is made possible by the San Diego Zoo Global Wildlife Conservancy and is supported in part by the Foundation of San Diego Zoo Global.
