prairie dogs. Because the bulk of the white-tailed prairie dog range is located on public land,<br />
poisoning can be controlled by agencies.<br />
White-tailed prairie dogs have become a focal species for many State and Federal management<br />
agencies over the past few years. Utah and Montana have implemented State-wide seasonal shooting<br />
closures on public lands to help conserve this species. The U.S. Geological Survey (USGS) and U.S.<br />
Department of Agriculture (USDA) are working on programs to monitor plague, develop methods to<br />
help prevent epizootics from impacting colonies and predict areas susceptible to infection. State<br />
agencies have started to monitor known colonies/complexes, map additional areas and work<br />
cooperatively with other agencies and among States to develop intensive monitoring programs using<br />
statistically valid estimation techniques. Elimination of detrimental management activities can be<br />
instituted to manage and potentially expand the occupied hectares of this species. By implementing<br />
management actions at local, State, and Federal levels, including regulation of shooting, elimination of<br />
mandatory control and pest status, incorporating better grazing and fire management practices,<br />
adopting incentive programs for private land owners, field research to provide a scientific basis for<br />
decisions, long-term monitoring of populations, and public outreach and education, the long-term<br />
viability of this species will be assured.<br />
At this time the White-tailed Prairie Dog Working Group does not believe listing the<br />
white-tailed prairie dog as threatened under the ESA is justified. The information analyzed across the<br />
range of the white-tailed prairie dog showed that some individual colonies and complexes are prone to<br />
significant declines with little post recovery to pre-decline levels, while other colonies and complexes<br />
exhibit rapid recovery to pre-decline levels. With the current data available it is impossible to<br />
determine whether populations across the range occur at lower densities and occupy less area than they<br />
did historically. It is also impossible to predict a long-term trend due to the short-duration in past<br />
monitoring (3-7 years) and the lack of definitive patterns emerging among the populations monitored.<br />
The fact remains however, that white-tailed prairie dog populations are continuing to maintain<br />
themselves even when faced with disease and human disturbances. The biggest concern is that the<br />
ecosystem as a whole is not as productive or stable as it was historically. Colonies and complexes<br />
show dramatic oscillations in densities and shifts in occupied habitat. With the possibility that current<br />
populations are more dynamic, there is concern over the viability of associated wildlife species that are<br />
dependent on white-tailed prairie dog populations.<br />
WHITE-TAILED PRAIRIE-DOG CONSERVATION ASSESSMENT<br />
Introduction<br />
Five species of prairie dog inhabit western North America and they differ with regard to<br />
current conservation status. The Mexican prairie dog (Cynomys mexicanus) is federally listed as<br />
endangered in Mexico (50 C.F.R), the Utah prairie dog (C. parvidens) is listed as threatened<br />
(17.11 CFR.) and the black-tailed prairie dog (C. ludovicianus), formerly a candidate species for<br />
listing (65 FR 5476-5488) is still of conservation concern. The white-tailed prairie dog was<br />
petitioned to be listed as threatened under the ESA on July 11, 2002, by the Center for Native<br />
Ecosystems, Biodiversity <strong>Conservation</strong> Alliance, Southern Utah Wilderness Alliance, America<br />
Lands Alliance, Forest Guardians, Terry Tempest Williams, Ecology Center and Sinapu. The<br />
Gunnison’s prairie dog (C. gunnisoni) was petitioned to be listed on February 23, 2004 (Forest<br />
