Wolves from Nez Perce Pen Split Apart

4/9/96.

The wolves from the new Nez Perce enclosure
have split into two groups. Both groups are far
from their release point which was about 10
miles north of Old Faithful on the west side
of the Park.

The alpha female left the pen early with
three female pups and was 30 miles NE of the
pen by Thursday morning. By Sunday the female
(27F) was 60 miles N/NE of the pen and outside
of the Park on the Shoshone National Forest.
Earlier I had reported that all the wolves
were together, but the large male (28M) remained
behind with one pup. The pup was helped out of
the pen by Park staff. By Sunday the alpha male
and pup were 45 miles to the north in the
northern part of Yellowstone Park. Both 27F and 28M
are very large gray wolves.

The wolves in the Nez Perce pen were a bison-
eating pack and biologists had hoped they would
stay together.

LONE STAR GROUP

35M and 36F had been placed together in the new
Blacktail Deer Plateau enclosure. On Friday they
were trucked to an area south of Old Faithful
and put in a temporary pen (with an open door). A
tracking flight on Saturday, April 6, showed
they had left the pen and were about a mile apart.
It is hoped that these two black wolves mated. For
now biologists call this the "Lone Star Group" due
to the proximity of their release to the Lone
Star Geyser.

35M and 36F were not released at the site of
their enclosure pen on the Blacktail Deer Plateau
because a new pack of last year's wolves had formed
there.

ROSE CREEK PEN

As of Sunday this group of five wolves still had
not left the Rose Creek pen. These are wolves
38 - 42. Except for the large adult male 38M,
these wolves were part of the Bessa Creek pack in
British Columbia.

CRYSTAL CREEK BENCH PEN

This group will be released somewhere other than
at Crystal Bench later this week.

LAST YEAR'S WOLVES
ROSE CREEK PACK

All nine of this pack were found together on
Sunday in the Lamar Valley.

CRYSTAL CREEK BENCH PACK

The remaining three in this pack were also
located in the Lamar Valley.

SODA BUTTE CREEK PACK

The four remaining members of this pack were in
upper Slough Creek just north of the Yellowstone Park
boundary. Two dispersers from this pack were shot
this winter -- no. 11F and no. 12M. Both had dispersed far
to the south and southeast of the Park. No. 11F was
shot by a ranch hand who turned himself in. He said the
wolf was mistaken for a coyote. I will post a more
detailed story on this later.

BLACKTAIL DEER PLATEAU PACK

This new pack (actually a pairing of two of last
year's wolves) was located on the Blacktail Deer
Plateau in the northern part of the Park.

In summary then, all of the wolves both old and
new, are in the northern or NE part of Yellowstone
Park or are just north of the Park with the exception of
the Lone Star pair. They are in the south central part of
Yellowstone.
