Conservationists are celebrating the 30th anniversary of the rediscovery of the black-footed ferret, a rare mammal which was once thought to be extinct.
The black-footed ferret is native to North America, where its natural habitat is prairie grasslands. Destruction of this habitat for agricultural purposes and eradication of its main prey, the black-tailed prairie dog, led to the rapid decline of the black-footed ferret population in the first half of the 20th century. Diseases such as canine distemper and plague further exacerbated this decline.
By the 1970s, the black-footed ferret was believed to be extinct, until in 1981 a farmer’s dog in Meeteetse, Wyoming, brought back a dead ferret to its owners. This discovery sparked the creation of the Black-Footed Ferret Recovery Program.
30 years of conservation
Since its rediscovery, the black-footed ferret has been the focus of concerted conservation efforts by U.S. federal and state agencies in cooperation with private landowners, non-profit organizations and Native American tribes. Captive breeding efforts have since produced some 7,600 ferrets, with reintroductions back to the wild beginning in 1991. There are now a total of 19 reintroduction sites, with 150 to 250 individuals being released each year.
The main goal of the current black-footed ferret recovery plan is to have the species downlisted as an endangered species by 2020, and completely removed from the endangered list by 2040. The biggest threats to this recovery are now a lack of suitable reintroduction sites and disease, although an effective plague vaccine has now been developed.
Kristy Bly of WWF said this of the success, “With 2011 marking the 30th anniversary of the rediscovery of the black-footed ferret, we now have more reason than ever to celebrate. Through these relocation efforts, we have established approximately 5,600 acres of prairie dog colonies, creating nearly half of the area needed to restore a self-sustaining population of black-footed ferrets to Thunder Basin grasslands.”
