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 />
