Captive Breeding

This month saw some great successes for wildlife and the climate — all made possible by decades of action and perseverance.

The tragic death, following an artificial insemination procedure, leaves just three turtles of the species alive.

The gigantic Ozark hellbender salamander is in trouble in the wild, but one zoo — and a hard-working team — is helping to boost its populations.

The death of a snail named George on New Year’s Day marked the extinction of his species. Saving the rest of Hawaii’s unique snails is a race against time — but not one without hope.

Conservationists have helped to save North America’s largest bird from extinction, but it’s still important to give every chick a chance to fly free.

As the wild population of red wolves falls to just 40 animals, captive breeding may be their last chance for survival.

Dozens of these water-filtering species are at risk of vanishing, and that’s bad news for every living creature that relies on them.

With just a few dozen left in the wild, things don’t look good for these critically endangered birds. But a captive-breeding program could help save them.

Only 35 Mount Graham squirrels remain in the wild, but five captive squirrels could hold the key to their long-term survival — if we can get them to breed.

The last 150 birds of this critically endangered species rely on humans for their survival.
