WYOMING WOLF WEEKLY- Feb. 23 through Feb 27, 2009

Web Address – USFWS reports (past weekly and annual reports) can be viewed at . Weekly reports for Montana and Idaho are produced by those States and can be viewed on the Montana Fish, Wildlife and Parks and Idaho Department of Fish and Game websites.

Status of the NRM wolf delisting rule 
As every new administration since Reagan has done, the Obama administration has put a hold on all new federal regulations that weren't finalized before Jan. 20.  Therefore, both the final NRM and WGL wolf delisting rules were withdrawn from publication pending further review by the new administration.  After further review three basic things could happen and could happen to either rule independently of the other.  The DOI/USFWS could decide to; 1) Re-submit to be published as written;  2) Modify or conduct further action before publication; 3)  Not publish them in order to take another course of action.  At this time the DOI/USFWS is reviewing all its options.  There is currently no timeframe predicted to make these decisions but they are a high priority within the USFWS. 

On 2/12/09, the YNP wolf project aerially darted and radio collared 7 wolves from 4 packs in YNP (Delta, Agate, Canyon, and Cottonwood Packs).

An 18 month old female wolf that was originally radio collared in SW Montana dispersed from her natal pack in September 2008. She has traveled from Montana, through parts of western Wyoming, SE Idaho, and NE Utah. Last week, locations from her GPS satellite collar indicated she was near Vail, Colorado, approximately 450 (straight-line) miles from her natal home range. It is a well documented fact that wolves can disperse extremely long distances, commonly over 500 miles and across huge expanses of habitat unsuitable for wolf pack persistence. These types of dispersal events are common. This incident only provides further evidence that genetic connectivity in the NRM wolf population is and will remain extremely high and is not a long term wolf conservation issue. Wolves in Colorado are listed under the ESA as endangered. Future locations of this wolf will be reported in the USFWS Weekly Report, posted on the USFWS website @

On 2/22/08, Wyoming WS confirmed that an adult pregnant cow was severely injured by wolves on private property near Meeteetse, WY.  Owners of the cow were considering euthanizing it. The USFWS requested WS to remove 3 wolves to minimize additional depredations because wolves in this area have chronically killed livestock over the past few years. On 2/24/09, one adult female wolf was removed and control is ongoing.

YNP will begin its late winter 30-day predation study on March 1. Research goals include prey selection, wolf-prey interactions, characteristics and composition of prey, and predation rates by wolves.
