National Wildlife Refuges
Where Wildlife Comes First
Created in 1903 by President Theodore Roosevelt, today's National Wildlife Refuge System protects habitats and wildlife across the country, from the Alaskan tundra to subtropical wetlands. Managed by the U.S. Fish and Wildlife Service, the Refuge System's 560-plus refuges cover more than 150 million acres and protect nearly 1,400 species of birds, mammals, reptiles, amphibians, and fish.
While national wildlife refuges were created to protect wildlife, they are for people too. Refuges are ideal places for people of all ages to explore and connect with the natural world. We invite you to learn more about and visit the national wildlife refuges and wetland management districts in Colorado, Kansas, Montana, Nebraska, North Dakota, South Dakota, Utah, and Wyoming.

Black-footed ferret (Mustela nigripes)
Since March 11, 1967, the black-footed ferret (Mustela nigripes) has been listed as endangered across its entire range, with the exception of several reintroduced populations designated as experimental. In November 2008, the Service completed a 5-year review of black-footed ferret recovery efforts. This review found that the species remains one of the most endangered mammals in the United States, and continues to warrant endangered status. Despite the radically-altered environment facing reintroduced ferrets today, scientists believe that the recovery of the species is within reach.
July 28, 2016 - Black-footed ferrets return home
This week, one of North America’s most endangered mammals, the black-footed ferret, took another step towards recovery thanks to a historic reintroduction back to the ranches where the species was rediscovered in 1981 after having been believed to be extinct. The Wyoming Game and Fish Department, in partnership with the U.S. Fish and Wildlife Service and the owners of two local ranches, released 35 black-footed ferrets. The ferrets were released on the Lazy BV and Pitchfork Ranches, outside Meeteetse, Wyoming.
On October 30, 2015, the U.S. Fish and Wildlife Service, with the support of the Wyoming Game and Fish Department, has finalized a 10(j) rule to designate the state of Wyoming as a special area for ferret reintroductions. The new rule will make it easier for willing landowners to host ferrets on their property.

Recent Actions: On April 10, 2015, the U.S. Fish and Wildlife Service (Service) published a proposal to establish a non-essential, experimental 10(j) area for the black-footed ferret throughout the state of Wyoming. This announcement opens a 60-day public comment period, which closes on June 9, 2015. A 10(j) designation under the Endangered Species Act (ESA) would increase management flexibility and lessen regulatory requirements related to future ferret reintroductions in the state of Wyoming. The goal of this proposal is to help facilitate new reintroductions of the black-footed ferret.

On December 20, 2013 the Service completed a revision of the 1988 Black-footed Ferret Recovery Plan in coordination with interested State, Tribal, Federal, and non-government organizations or agencies within the historical range of the species, as well as through a review of public comments. The black-footed ferret will benefit from purposeful management of a portion of existing prairie dog habitat in 12 western states; it is obligate predator of prairie dogs and depends upon their burrows for shelter. The Black-footed Footed Recovery Implementation Team, composed of representatives of the aforementioned organizations and agencies, will use the Revised Black-footed Ferret Recovery Plan to help guide future conservation efforts for the species.

On October 23, 2013, the Service issued a permit for the Black-footed Ferret (BFF) Programmatic Safe Harbor Agreement (SHA), created in cooperation with State, Tribal, Federal, and local partners in 12 states. This SHA provides opportunities for private and Tribal landowners to volunteer their lands as sites for reintroduction of this endangered species without affecting their land-use activities beyond mutually agreed-upon measures. It also extends these assurances to surrounding non-participating lands and other landowner interests via a Section 7 Biological Opinion (BO) for the SHA. This SHA approach will be an important step in promoting the recovery of this iconic species. The BFF SHA, BO, NEPA documents, and Set of Findings are available below.
The Service in coordination with Colorado Parks and Wildlife, block-cleared various areas of Colorado, after determining that these areas no longer contain any wild, free-ranging black-footed ferrets. Block clearance means that activities within these areas that result in the removal of black-tailed prairie dogs or their habitat will no longer be required to meet the Service survey guidelines for black-footed ferrets, or undergo consultation under section 7 of the ESA.
Threats: Despite significant recovery successes, the black-footed ferret remains one of the most endangered animals in the world. The primary reasons the species remains at risk are the same that nearly caused the animal’s extinction: loss of habitat and prey. Conservation or native grasslands to agricultural land, widespread prairie dog eradication programs, and fatal, non-native diseases have reduced ferret habitat to less than two percent of its original range. The remaining habitat is now fragmented, with prairie dog towns separated by expanses of agricultural land and other human developments.
Population Numbers and Recovery Efforts: Scientists believe that black-footed ferrets once numbered in the tens of thousands, but a combination of human-induced threats brought them to the brink of extinction in the 20th century. In fact, the species was twice believed to be extinct. In 1987, only eighteen individuals were known to exist in the entire world. Scientists captured these ferrets, which provided the foundation for a successful breeding and reintroduction program that continues today.
In order to meet delisting goals the Black-footed Ferret Recovery Plan calls for 3,000 individuals in populations of 30 or more adults, with at least 10 populations of 100 or more individuals, and at least one population occurring in at least nine of the 12 states in the species’ historic range.
Due to the nocturnal and fossorial (underground-dwelling) nature of the species, monitoring of reintroduced populations is challenging, but experts estimate that there are likely several hundred individuals disbursed across relocation sites in 8 western states, Mexico, and Canada. Importantly, black-footed ferrets have a high reproductive rate and even small populations can expand rapidly to fill adequately managed habitat where disease management is in place.
These recovery efforts are managed primarily by the National Black-Footed Ferret Conservation Center in Colorado. All components necessary to achieve recovery have been identified, and have proven operationally successful in the field. That said, there is still much work to be done, and many potentially complicated variables still exist. However, if recovery efforts continue at the current pace and do not experience significant setbacks, in time the Service and its partners expect to recover the black-footed ferret.

In December 2008, the Service reintroduced black-footed ferrets to Logan County, Kansas. The primary objections of the proposed action are to experiment with reintroduction of ferrets into much smaller prairie dog colonies than has traditionally been attempted; and to attempt to establish a self-sustaining population outside the known active occurrence of sylvatic plaque.
