North America's rarest wolf species, the red wolf, was on the brink of extinction.

At one time, red wolves roamed the US from southern New York to as far south as Florida and as far west as Texas. But as European settlers moved in, these wolves began losing their home range and were hunted as a threat.

Red wolves became so rare by 1973 that they were given protection under the US Endangered Species Act. Then scientists came up with a daring plan: round up all remaining red wolves, launch a captive breeding program, and once the captive population was large enough, release red wolves to roam free in protected areas.

Follow along as scientists, conservationists, and wildlife experts join forces to help red wolves live wild again.
