Habitat Management Series for Endangered Species. Report Number 2. Black-Footed Ferret 'Mustela nigripes'

摘要

The Black-footed Ferret, Mustela nigripes, is a member of the weasel family. The former and present distribution of the black-footed ferret is essentially the same but evidence points to a swift decrease in the number of ferrets over most of the present range. Montana, Wyoming, Colorado, South Dakota, North Dakota, New Mexico, Arizona, Texas, Oklahoma, Kansas and Nebraska. Official policy has been the protection of the black-footed ferret but there have been some difficulties in implementing procedures. At present there is a great lack of knowledge concerning the ferret's life history and ecology, including what effect prairie dog control has on ferret populations.
