ESTIMATING POPULATIONS OF PRAIRIE DOGS 859 Comparison of methods to estimate population densities of black-tailed prairie dogs Kieth E. Severson and Glenn E. Plumb Abstract Recent reintroduction of the black-footed ferret (Mustela nigripes) in west-central South Dakota has focused new attention on black-tailed prairie dogs (Cynomys ludovicianus), Once emerged from their burrows, but before the end of lactation, some pups will nurse from female prairie dogs other than their mother, in what is called ‘cooperative breeding’. The black-tailed prairie dog is a rodent species with tan coloured fur that is paler on their fronts than on their backs. METHODS: Annual black-tailed prairie dog population surveys are conducted after young-of-the-year prairie dogs have emerged from their burrows and yearlings have dispersed (mid-June to late August). 2). It is a large (adult total length 370 mm, weight 820 g) ground squirrel with a robust, stocky body and short legs. The species is extirpated from east Texas north to eastern North Dakota, and where it remains the actual area occupied is small and colonies are mainly small and isolated. 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. Providing leadership in the conservation of migratory bird habitat through partnerships, grants, and outreach for present and future generations. Features of the skull and teeth can also be used to separate the two species of prairie dogs in Montana (Foresman 2012). However, Fagerstone and Biggins (1986) and Menkens et al.

After review of a petition seeking to protect the black-tailed prairie dog under the Endangered Species Act (ESA), the Service will undertake a more thorough review of the species to determine whether to propose adding the black-tailed prairie dog to the list of threatened or endangered species. A colony of the highly social black-tailed prairie dog (Cynomys ludovicianus) was studied in the field for 16 years, and data were gathered for estimation of effective population sizes from pedigrees, demography, and allozyme alleles. Being primary consumers, they provide a vital link in food webs. Black-footed ferrets are considered extirpated except where they have been purposely reintroduced using special authorities under Section 10 of Endangered Species Act.  For project planning purposes, please consult IPaC (https://ecos.fws.gov/ipac/) to determine if pre-construction black-footed ferret surveys are required, or contact your local Ecological Services Field Office. Life History Prairie dogs play an important role in the prairie ecosystem.
