Alpha females in both the Slough Creek Pack and Druid Peak Pack have bred with more than one wolf (286F with 302M, as well as the "new black" (also known as 480M). Also, more than one female wolf in the Slough Creek Pack have bred, thus making a possibility of large numbers in the Slough Creek Pack this year.

There are already 15 or more Slough wolves and only 6 Druid wolves as Druid female 375F was recently found dead.

The alpha female [and only radio-collared member] of the Buffalo Fork pack was found dead on the 14th. She had recently nursed pups but the remaining 4 pack members should be able to successfully rear them. She was apparently killed by other wolves and the Rose Creek pack only a mile or so away from her carcass.

The carcass and radio-collar of a pup from the Sentinel pack south of Bozeman that darted last winter was recovered. The carcass was intact but very decayed and the wolf had been dead for some time. Cause of death did not appear to be caused by illegally.

Therese Hartman, assisted by volunteers Kassy Holzheimer and Elizabeth Morton, captured and radio-collared a yearling female wolf from the Spotted Bear Pack on June 19.

WE NEED HELP FROM COOPERATORS AND PUBLIC- We are currently into the trapping season, when we try to radio-collar wolves from previously unknown packs and beef up our collar coverage in known packs.

Please report any sightings of wolf activity to the nearest U.S. Fish and Wildlife Service, state Fish and Game Agency, Forest Service, BLM, Tribal, or USDA Wildlife Services office.


Herders watched as a lone wolf killed a 200lb calf in central Idaho, just north of Arco. They couldn�t react fast enough other than to drive the wolf off the carcass. WS confirmed the loss and traps have been set near the calf�s carcass. If the wolf is captured it will be killed.

The remains of a calf, found near Trego, MT about June 5, were thawed out and examined by Wildlife Services specialist Ted North. He determined that the calf had not died of predation. WS specialist McDougal also examined a dead calf near Big Hole, MT from last week, and it was also not killed by predators. There have been very few depredations by wolves so far this summer.


Yellowstone National Park was trying to examine summer wolf predation by monitoring members of the Druid pack using GPS locations [multiple locations are taken each day] were that are downloaded weekly. Unfortunately the GPS collars don�t seem to be functioning properly and were only transmitting a couple of locations per day. That isn�t frequent enough to determine of wolves route of travel and identify location clusters to look for summer kills.

Capture and monitoring of elk calves to document the cause and rate of neonate mortality is continuing in Yellowstone Park as part of a PhD. Research project.

Education, Information and Law Enforcement

Doug Smith gave several talks this past week. He spoke to abut 200 people at the GYC 20th anniversary annual meeting in West Yellowstone on the 13th. He talked to about 100 park visitors at the Tower Hotel and several dozen a teachers at their workshop in the Park. He also talked to several Yellowstone Foundation members on the 20th.

Bangs talked with about 20 FWS R-6 Reality Specialists at their retreat and meeting at Big Sky, MT on the 17th. On the 18th Bangs spoke to about 30 Missoula Rotary members in Missoula, MT.

Asher met with several ranchers from the Taylor Fork area of Montana, south of Bozeman, MSU researchers, and MT FW&P. It appears there was some confusion among the local residents over who was ultimately responsible for wolf-related issues and who should be contacted. The rules are: for dead wolves you go to FWS law enforcement, livestock losses to Wildlife Services, and everyhthing else goes to the Service, although MT FW&P and the Univ. can certainly help out or pass information along. Val Asher is the representative for the USFWS in that area. The meeting went well and it was clarified that the USFWS is the only agency with direct wolf-management authorities while wolves are listed. After delisting MT FW&P would be the sole lead management agency. The University is simply conducting some cooperative research under a FWS and/or MT FW&P permits.

Asher is going down to assist the Mexican wolf program next week. She will be helping to relocate and release some wolves into their backcountry Wilderness using pack mules.

The U.S. Attorney�s Office in Boise, Idaho filed a request for a clarification of the Judge�s order regarding its prohibition of "any" wolf control in the Sawtooth National Recreation Area on the 18th. The FWS asked that non-lethal measurers be allowed by the court should there be a depredation. The Service assisted in preparing that request and appreciates DOJ�s efforts.

On Friday, Bangs met with a USA Today reporter who is writing about the success of wolf and grizzly bear recovery in the western United States.

Death of last Original Wolf Reintroduced in 1995

Information from the National Park Service indicates that male wolf #2 was probably killed by other wolves. His body was found on 31 December 2002.

Wolf #2 was the Alpha Male of the Leopold Pack that was established in spring of 1995. He was one of the original wolves captured in Canada and released in Yellowstone. This was the very beginning of the wolf restoration project in Yellowstone and Idaho.

It is believed that wolf #2 was disposed as the Alpha Male and driven out of the pack. As a lone wolf he was vulnerable to other wolves if he strayed into their territory. Wolves are very territorial and have been known to kill or injure other wolves that enter their pack area.

Wolf #2 was eight years old at the time of his death and may have sired at least eight litters of wolves.

Leopold Pack info from Wolf History - Established 1995

Pack History: The Leopold Pack has the distinction of being the first free forming pack in Yellowstone National Park and is named after Aldo Leopold a noted conservationist and a pioneer of wolf restoration. Striking out on their own as 1.5 year old wolves often do, female #7 from the original Rose Creek Pack and male #2 from the Crystal Creek Pack spent time as "lone wolves", wandering the park. We were excited to learn that they have joined together. They have staked out a territory and have been observed exhibiting courtship behavior. Pups are expected in the spring of 1996.

Leopold Pack - 1995

The Leopold Pack, named after the late biologist Aldo Leopold, is the result of two dispersed wolves coming together. The Alpha Female #7, was from the Rose Creek Pack and is #9's daughter, and the Alpha Male #2, was from the Crystal Peak Pack. Wolf #7 dispersed soon after #9 and #10 went north of the park in the spring of 1995 in search of a den site. She was on her own for approximately nine months until she began consorting with #2. This union is especially significant because the pair is the first naturally-forming wolf pack in Yellowstone since wolves were eradicated more than 60 years ago. In addition, the two have produced a litter of three pups in April 1996. The five pack members are now seen by biologists at a rendezvous site located in the northern portion of Yellowstone in the Blacktail plateau area.

Pack Location: The pack is located in the Blacktail area of northern Yellowstone.
