An Experimental Translocation of the Eastern Timber Wolf
Weise, Thomas F.
Gray wolf -- Reintroduction -- Michigan
Wolf No. 10 never joined any of the other radioed wolves after their
release, whereas the others generally remained as a pack. Thus the
movements of the pack will be described separately from those of lone
wolf No. 10.
Four phases were seen in the movements of the pack: (1) Post-Release
Phase, March 12 to 14; (2) Directional Movement Phase, March 15 to 24;
(3) Exploratory Phase, March 25 to May 7, and (4) Settled Phase, May 7
to July 6.
Post-Release Phase
This first phase of the wolves' movements, including the first 2 days
after release, seemed to be characterized by confusion and indecision.
On March 13, the morning after the release, the three wolves were
separated, but all remained within 2.0 miles (3.2 km) south to west of
the release site, the general direction in which they had headed upon
release (Fig. 17). No. 11 and 13 were about a half-mile (0.8 km) apart
in the morning, and by late afternoon, No. 13 apparently had joined No.
11. No. 12 remained about 2 miles away from the others all day, although
he did move about a half-mile during the day. By the 14th, No. 11 and 13
had moved 2 miles southwestward, but were separated by a half-mile; No.
12 had moved only a half-mile west.
Directional Movement Phase
During this phase, all three wolves left the immediate vicinity of the
release point and headed southwestward. Early in this phase, wolves No.
11 and 13 rejoined (by March 15) and traveled 9 miles (14.5 km)
west-southwest of their previous day's location, while No. 12 took a
more northerly route. Nevertheless, by March 19, No. 12 had joined the
other two wolves near Skanee, some 14 miles (22.5 km) west-southwest of
the release point (Fig. 17). For the next several weeks these wolves all
remained together and travelled a straight-line distance of about 40
miles (64.1 km) to a point just north of Prickett Dam about 11 miles
(17.6 km) west-southwest of L'Anse, arriving there on March 24 (Fig.
17).
Exploratory Phase
In the Exploratory Phase of their movements, from March 25 to May 7,
wolves No. 11, 12, and 13 covered a 1,631-square-mile (4,224 km^2) area
from the town of Atlantic Mine on the Keweenaw Peninsula to the north to
a point about 64 miles (103.0 km) south, near Gibbs City (Fig. 18). In
the opposite dimension, they ranged from Keweenaw Bay on the east to 9
miles (14.5 km) south of Ontonagon, 42 miles (67.6 km) west of there.
This phase was characterized by long movements, considerable
zigzagging, and revisiting of certain general regions such as the base
of the Keweenaw Peninsula and areas east and north of Kenton (Fig. 18).
