Idaho Wolf Update
February 12, 1999
Gray wolves identified in these updates are referenced as B-XX-Y. The B identifies the wolf as a
central Idaho animal, numbers identify individuals and the Y indicates male (M) or female (F).
North of the Salmon River
Panhandle, Clearwater, and Lolo National Forests
The Snow Peak pack including alpha wolves B-20-F and B-31-M and their 5 pups remain in the upper St. Joe
and North Fork drainages. Alpha male wolf B-31 has not been located since November. His radio collar has
been malfunctioning for over a year and is suspected to have failed.
The Kelly Creek pack including alpha wolves B-15-F and 9013-M continues to use the upper Kelly Creek
drainage and surrounding country along the Bitterroot divide north of Lolo Pass. This pack remains
loosely associated with individual and small groups of wolves fragmenting across large areas of their
home range. Pack members have spent much of their time in winter range along the Cache and Fish Creek
The Big Hole pack including alpha wolves B-11-F and B-07-M and their 5 pups continues to frequent
habitats on the Bitterroot divide just south of Lolo Pass on the Lolo and Clearwater National Forests.
Lone wolf B-51-F has not been located for the past several monitoring flights due to persistent bad
weather. She was last located in the Big Sand Creek drainage near Elk Summit on the Clearwater
Lone wolf B-52-M has not been located for the past several monitoring flights due to persistent bad
weather. He was most recently located in the Fog Mountain Saddle area north of the Selway River,
about 15 air miles south of his relocation site.
Lone wolf B-54-F has not been located since she was relocated to the Selway Bitterroot Wilderness late
Nez Perce National Forest
The Selway pack has only been sporadically located this winter because of inclement weather. These
wolves were last located within their usual home range just east of Salmon Mountain along the divide
between the Selway and Salmon Rivers.
South of the Salmon River
Payette National Forest
The Chamberlain Basin pack including alpha wolves B-09-M and B-16-F have most recently been located
within the Big Creek drainage, tributary to the Middle Fork of the Salmon River.
The Thunder Mountain pack including alpha female wolf B-22-F, her mate of unknown origin, and their
5-6 pups have most recently been traveling within the Marble Creek drainage, tributary to the Middle
Fork of the Salmon River.
Boise National Forest
Wolf B-33-M continues to move widely. During October and November, he spent time in the Middle Fork
of the Salmon. During January, he was observed twice with one other wolf and concentrated his movements
around the north end of Bear Valley. He was last located just east of Landmark, Idaho.
Female wolf B-30, of the Bear Valley pair, is suspected to have died this fall. Her collar went on
mortality mode in December. Efforts to retrieve her collar have not been successful due to inaccessible
and rugged terrain, and poor weather conditions. Her mate, male wolf B-28 has since traveled east and
was most recently located just north of Stanley, Idaho within the Stanley Basin pack's territory.
Salmon-Challis National Forest
Wolf B-19-M was found dead along the upper Loon Creek drainage in early January. Evidence indicated
that he was killed during inter-pack aggression with the Twin Peaks pack. The whereabouts and fate of
his un-collared mate is unknown.
The Jureano Mountain pack including alpha wolves B-25-F and B-32-M continue to travel through much of
their established home range. Two subadults dispersed from this pack this fall. Yearling male wolf
B-41 traveled north and was hit and killed by a vehicle along U.S. Highway 12 near Lolo, MT. His
sibling, yearling female wolf B-45, has been missing since last fall.
The Moyer Basin pack including alpha pair B-29-M and B-37-F continues to use areas surrounding the
upper Panther Creek drainage including the Moyer Basin area, upper Silver and Morgan Creek drainages,
and Camas Creek.
The Twin Peaks pack including alpha wolves B-35-F and B-18-M have spent most of the winter in winter
range of the upper Loon Creek and Warm Springs Creek drainages.
Sawtooth National Forest
The Stanley Basin pack including wolf pair B-23-F and B-27-M continues to move throughout the Stanley
Basin. This pack continues to be loosely associated through the winter months. Members of this pack
travel along winter range of the main Salmon River from the mouth of the Yankee Fork of the Salmon River,
north of Stanley, Idaho, to Champion Creek near the town on Obsidian, Idaho.
The White Cloud pack including alpha female wolf B-36-F have concentrated their winter movements within
winter range along the East Fork of the Salmon River. This pack was implicated in livestock depredations
on private land during February (see Control).
The Nez Perce Tribe, US Fish and Wildlife Service, Lemhi County, Hornocker Wildlife Institute, University
of Idaho and other contributors including the U.S. Forest Service, Idaho Department of Fish and Game,
Wolf Education and Research Center, and the Rocky Mountain Elk Foundation are cooperating on two winter
studies to assess interactions between wolves and mountain lions and predation on wintering ungulates.
Program personnel held fall outreach meetings with livestock producers in Salmon and May Idaho. Program
personnel presented at the Lemhi County and Idaho State Cattle Association, and Idaho State Outfitters
and Guides annual meetings. Program personnel attended and participated in Idaho State Legislative Wolf
Oversight Committee meeting, and Idaho Gray Wolf Recovery coordination meetings. Program personnel
provided an update on the status of wolves in Idaho to a joint Idaho Legislative House and Senate Natural
Resources Committee meeting. Program personnel provided special presentations for the Defenders of
Wildlife and National Wildlife Federation. Program personnel presented at the Clearwater Flycasters
In early February, the White Cloud pack was suspected of depredating on new born calves on private
property along the East Fork of the Salmon River. This pack has spent most of the winter months along
prime winter range of the East Fork along with large numbers of elk and deer. The White Cloud pack
established their territory in 1998, and is composed of the alpha breeding pair and up to 9 pups. In
hopes of discouraging future depredations, two male pups were darted from a helicopter and fitted with
radio collars, during a cooperative effort between the Nez Perce Tribe, U.S. Fish and Wildlife Service,
Wildlife Services, and Lemhi county. Both pups were released on site. Managers hope that the disturbance
to the pack from the capture effort will encourage the pack to move away from calving grounds. The
additional collars will also aid the Tribe to monitor the movements of these wolves through the winter
