Recovering A Species: The Red Wolf
"This is the story of the Red Wolf, an animal nearly annihilated in the North American wilderness by hunting, trapping, and human development. By 1967, the Red Wolf was America's most endangered species. So in the mid 1970's, biologists began capturing the last remaining wolves in search of any purebred animals before they were lost.
After an extensive search, the biologists found only 17 purebred Red Wolves. Due to the severity of the situation, in 1987, biologists developed a captive breeding program and a scientific plan to return Red Wolves to the wild."
