Ideology
Captive breeding programs often feature endangered species in a safe environment where biologists provide the ideal environment for mating. Many wildlife preserves will not act as safe havens for rare animals because of poacher activity. Predator activity in the region also threatens any endangered species released into the wild. While some people question the expense of setting up captive breeding programs, many biologists and zoologists voice their support of such programs.
Notable Successes
Several endangered species recovered and repopulated in the wild due to successful captive breeding programs. The bald eagle remains one of the greatest success stories. Once severely endangered, the eagle is off the endangered species list and flourishes throughout the United States. Captive breeding programs helped prevent the extinction of red wolves, black footed ferrets and California condors.
Notable Failures
While advocates of captive breeding programs point to the successes, many detractors point to a wide array of well-publicized failures. Giant pandas, lowland gorillas and snow leopard populations show no statistically relevant benefit from captive breeding. Several female giant pandas in captivity refuse to mate, forcing biologists to use artificial insemination to get female pandas pregnant.
Wilderness Reintroduction
Ideally, captive breeding eventually results in reintroduction of the species into the wild. Once bred into greater numbers, species reintegrate into an appropriate environment. Areas featuring enough males and females should serve as a natural breeding ground, allowing for full recovery. Park rangers and biologists closely monitor released animals to protect them from poachers and track all aspects of the recovery.
