outreach program which includes a zoomobile for outreach to locations outside the city, a summer camp, and a large volunteer program for teenagers 13–17, known as the Zooteen program. Conservation efforts Since opening in 1962, the zoo has focused on animal conservation efforts. Programs at the Phoenix Zoo include captive breeding for reintroduction (for instance the Arabian oryx, black-footed ferret, Mexican wolf, Ramsey Canyon leopard frog, and thick-billed parrot, sanctuary for animals that are no longer breeding (for instance the African painted dogs at the zoo), and rescue and rehabilitation (for instance lead poisoning treatments for the California condor). The Phoenix Zoo participates in the Species Survival Plan (SSP) for 29 species with the Association of Zoos and Aquariums. The goal of the SSP is to engage in animal husbandry and research projects for selected species that are in need of conservation efforts. Reintroduction In its first years, the zoo hosted a captive breeding program ("Operation Oryx") with the specific goal of reintroducing the almost extinct Arabian oryx to the wild. By the early 1990s this program was still one of only two programs (the other being the golden lion tamarin) to have gone through the full wilderness-zoo-wilderness sequence. Nine oryx had been caught or donated for the breeding program. However, two pairs were delayed, so the "World Herd" was started in Phoenix in 1963 with only five animals shipped to the zoo and two born quickly after. The two delayed pairs arrived in 1964 to increase the herd to 11 individuals. The program was very successful, and the zoo celebrated its 225th Arabian oryx birth in 2002. The Arabian oryx became extinct in the wild in 1972, and reintroduction efforts were started in 1982 when oryx were released to the wild in the Omani Central Desert and Coastal Hills. Additional captive herds have been discovered and used as the basis for reintroductions, for instance in Saudi Arabia, but there has been some interbreeding even with these herds and most of the Arabian oryx in the wild today have ancestors from the Phoenix Zoo. Sanctuary The zoo provides sanctuary to many animals that need a place to live for various reasons. Some (like the Arabian oryx, Bali mynah, rhinoceros hornbill, Mexican gray wolf, and white rhinoceros) participate in captive breeding programs, some (such as the African spotted dogs) have retired from such programs and need a home, some have behavioral
