WYOMING WOLF WEEKLY- June 28 through July 9, 2010

Web Address – USFWS reports (past weekly and annual reports) can be viewed at .   All weekly and annual reports are government property and can be used for any purpose.  Please distribute as you see fit.

2009 Annual Report
The 2009 Interagency Annual Wolf (Canis lupus) Report for the NRM DPS in 2009 can be viewed on-line at .  The Idaho and Montana state sections of the annual wolf report are also available on-line at the websites for Montana Fish, Wildlife and Parks and Idaho Department of Fish and Game  The annual wolf report is composed of five Sections: 1) Montana; 2) Wyoming; 3) Idaho; 4) USFWS overview of dispersal, funding, litigation, and relevant publications; and 5) Tables and Figures of wolf population statistics and wolf depredations. 
Litigation Status
Wyoming: Oral arguments were heard in federal court in Cheyenne, WY on January 29 to address the state of Wyoming’s request that the USFWS accept the Wyoming Wolf Management Plan. A decision from Judge Allen Johnson is pending.

Northern Rocky Mountains: Oral arguments were heard in federal court in Missoula, MT. on June 15. The court will address the Service’s approach of conferring ESA protections to a “significant portion of the range” of a species, as opposed to designating the entire species as a threatened or endangered species. Judge Malloy said he would issue a decision as soon as possible.


Monitoring: At least 14 packs have denned this spring in Wyoming (outside YNP), including: Absaroka, Beartooth, Buffalo, Chagrin River, East Fork, Elk Fork Creek, Green River, Hoodoo, Huckleberry, Pacific Creek, Phantom Springs, Pinnacle Peak, Sunlight, and Owl Creek.

Wyoming: We continue to manage wolf population growth and wolf distribution to minimize chronic loss of livestock from wolves and promote wolf conservation by maintaining the Wyoming wolf population (outside YNP) well above recovery objectives.

Control actions in Wyoming during the week of June 21-25 were incorrectly reported by the local news media. As of 7/9/10, a total of only one entire wolf pack (Dempsey Basin Pack) has been removed. This pack consisted of a pair of wolves and their 6 pups that recently formed NW of Kemmerer.

On 7/5/10, WGFD investigated a possible black bear depredation of sheep on a USFS public grazing allotment in the Dog Creek drainage, south of Jackson, WY and concluded that 4 sheep had been killed by a wolf (wolves). Wyoming Wildlife Services is investigating the incident.

On 7/7/10, Wyoming Wildlife Services confirmed that an adult cow was killed by wolves on private land in the Sunlight Basin, west of Cody, WY. Three additional dead cows were found in the same pasture and died from causes other than predators (possibly Larkspur poisoning). The rancher moved his cattle to a different pasture to avoid wolves and to resolve problems with Larkspur. We will continue to monitor the wolves in this area closely.

On 7/7/10, WGFD was asked to investigate (for purposes of state-funded livestock depredation compensation) 1 dead calf, 1 severely injured calf that was not expected to survive, and 1 injured calf that may survive. The depredations occurred in the Upper Green River drainage on a USFS public grazing allotment. Wyoming Wildlife Services is investigating the depredations.

Table 2. Confirmed livestock depredations and control actions in WY from 2003 - 2010.

*One foal was killed by wolves (recorded as confirmed), 2 horses were chased by wolves and injured when they were run through a fence (recorded as 1 confirmed and 1 probable), and 1 horse was chased by wolves and broke its leg when it was run over a cattle guard (recorded as probable). All 3 injured horses had to be euthanized.
** One additional calf was injured in the Upper Green River drainage. It is not certain if the calf will survive.

Outreach and Education

Mexican Wolf Recovery Program - Two job announcements:
1) Field coordinator in the Mexican wolf recovery program.

Anyone can find the two announcements (one public DEU; the other for government employees) via the search engine at USA jobs during June. They can also try the following link:

View the position advertisement summarizing additional information.

2) Wolf biologist to work on the Mexican Wolf Program at the New Mexico Dept. of Game and Fish.
The position will supplement an existing Department wolf biologist on the same program. We’re looking for someone that has a little experience with large carnivores and who can relate to the local stockmen.
