2001 it was estimated that there were 777 white rhinos in captivity worldwide. The San Diego Zoo Safari Park in San Diego, California, US had two northern white rhinos, one of which was wild-caught. On 22 November 2015, a 41-year-old female named Nola (born in 1974), which had been on loan from the Dvůr Králové Zoo in Dvůr Králové, Czech Republic) since 1989, was euthanized after experiencing a downturn in health. On 14 December 2014, a 44-year-old male named Angalifu died of old age at the San Diego Zoo. The other four captive northern white rhinos were loaned to Ol Pejeta Conservancy in Kenya, and only two remain alive. Females Najin and Fatu are still living, while males Suni and Sudan died in 2014 and 2018, respectively. The northern white rhinos had been transferred to Ol Pejeta Conservancy from the Dvůr Králové Zoo in 2009 in an attempt to protect the taxa in their natural habitat. The only two northern white rhinos left are maintained under 24-hour armed guard in Kenya.
