    National Park Service Bryce Canyon U.S. Department of the Interior Bryce Canyon National Park Utah Prairie Dog (Cynomys parvidens) All photos by Kevin Doxstater Prairie Dogs are ground-dwelling members of the squirrel family found only in North America. There are five species within the genus and the Utah Prairie Dog is the smallest member of the group. Restricted to the southwestern corner of Utah, they are a threatened species that has suffered population declines due to habitat loss and other factors. Vital Statistics Utah Prairie Dogs range from 12 – 16 inches Dog . Utah Prairie Dogs reach maturity in (30.5 – 40.6 cm) in length and weigh from 1 year; females have a life span of about 1 – 3 pounds (.45 – 1.4 kg).

  • Status Review Finding for the Black-Tailed Prairie Dog
    QUESTIONS AND ANSWERS REGARDING THE STATUS REVIEW FINDING FOR THE BLACK-TAILED PRAIRIE DOG What are the findings of the black-tailed prairie dog status review? The U.S. Fish and Wildlife Service has completed a status review of the black-tailed prairie dog and has determined it does not warrant protection as a threatened or endangered species under the Endangered Species Act. The Service bases its conclusion for this finding after a thorough review of all the available scientific and commercial information regarding the status of the black-tailed prairie dog and the potential impacts to the species. What is a status review? A status review, also known as a 12-month finding, makes public the Service=s decision on a petition to list a species as threatened or endangered under the Endangered Species Act. The finding is based on a thorough assessment of the available information on the species, as detailed in the species= status review. One of three possible conclusions can be reached as part of the finding: that listing is warranted, not warranted, or warranted but presently precluded by other higher-priority listing activities involving other species. In the case of black-tailed prairie dog, the Service found that the black-tailed prairie dog is not likely to become a threatened or endangered species within the foreseeable future in all or a significant portion of its range. Therefore, listing of the black-tailed prairie dog as a threatened or endangered species under the Endangered Species Act is not warranted at this time. What specifically does the Service look at to determine if a species needs to be listed as threatened or endangered? We consider the factors specified in the Endangered Species Act to determine whether a species meets the definition of “threatened” or “endangered” per the criteria stated in the Act.

  • Recovery of the Utah Prairie Dog: Public Perception and Cattle Grazing As a Management Tool
    Amendment to the Biological Assessment for the Potential Effects of Managing the Payette National Forest on the Northern Idaho Ground Squirrel Brownlee River Section 7 Watershed Volume 2 Ongoing and New Actions 29 September 2008 Payette National Forest McCall, Idaho Prepared by: 29 September 2008 Ana E. Dronkert Egnew Date Forest Wildlife Biologist Payette National Forest Preparation Assistance by Rodger Nelson Acting Forest Fisheries Biologist Payette National Forest I. INTRODUCTION — SUMMARY OF AMENDMENTS A. AMENDMENT TO THE DESCRIPTION OF THE FEDERAL ACTION AND DETERMINATION OF THE EFFECTS OF LIVESTOCK GRAZING ALLOTMENTS This document amends Biological Assessment for the Potential Effects of Managing the Payette National Forest in the Brownlee Section 7 Watershed on Northern Idaho Ground Squirrel and Lynx (Richards and Dronkert Egnew 2008a). The determination of effects to northern Idaho ground squirrel (NIDGS) from the Lick Creek, Bear Creek, Wildhorse/Crooked River, Steves Creek, and Smith Mountain livestock grazing allotments was May Affect, Not Likely to Adversely Affect (NLAA). The analysis and rationale for the determination is provided on pages 54-56 of Richards and Dronkert Egnew (2008a). Based on additional information and discussions by the Level 1 Team members, we have decided that the potential for effects are low, but not negligible; therefore, our determination is revised to: May Affect, Likely to Adversely Affect (LAA). Revision of our original determination was based in part on direction provided by regulatory agencies (National Marine Fisheries Service and Fish and Wildlife Service) on effects determinations for listed species (emphasis added): The conclusion that a project is not likely to adversely affect a listed species is appropriate when effects on listed species are expected to be discountable, or insignificant, or completely beneficial.

  • Black-Tailed Prairie Dog
    APPENDIX A SPECIES ACCOUNT: BLACK-TAILED PRAIRIE DOG 34 Black-tailed Prairie Dog (Cynomis ludovicianus) Species Status In 1998, two petitions were received by the U.S. Fish and Wildlife Service (USFWS) to list the black-tailed prairie dog (Cynomis ludovicianus) as threatened under the ESA of 1973, as amended (USFWS 1999). One petition, dated July 30, 1998 was from the National Wildlife Federation (NWF) and the second petition, dated August 26, 1998 was from the Biodiversity Legal Foundation, the Predator Project and Jon C. Sharps. In these petitions, several factors were listed as major threats to the long-term viability and conservation of this species. These included habitat loss, habitat fragmentation, disease, unregulated shooting and poisoning, and combinations of these, and other factors. In response to these petitions, in February 2000 the USFWS’s 12-month finding was that the black-tailed prairie dog was warranted but precluded for listing under the ESA (USFWS 2000). The USFWS believed that a threatened listing was warranted. The black-tailed prairie dog was not listed at that time, however, as resources needed to complete the process were not available. Description and Taxonomy Prairie dogs are small, diurnal, burrowing rodents. Specifically, there are five species of prairie dog in North America, three of which are found in Colorado. The species found in Colorado are the black-tailed prairie dog, white-tailed prairie dog (C. leucurus) and Gunnison’s prairie dog (C. gunnisoni). A subspecies of black-tailed prairie dog is sometimes mentioned (Cynomys ludovicianus arizonensis). Studies on evolutionary divergence, however, indicate that the black- tailed prairie dog is monotypic (USFWS 2000).
