At least in some areas, wolves are territorial (Mech 1972, 1973), and
the sizes of their home ranges are restricted somewhat by boundaries
established by the scent marks of surrounding packs (Peters and Mech
1975). The introduced wolves probably encountered no native packs with
established territories (Hendrickson et al. 1975), so they would not be
similarly restricted. The total area that wolves No. 11, 12, and 13
explored, 2,918 square miles (7,586 km^2), is larger than any reported
from the Great Lakes area and is comparable to home ranges of "tundra
wolves" (Mech 1970). Even the area in which they settled (May 7 to July
6) until the deaths of the males was 246 square miles (637 km^2), which
is larger than most reported ranges in the Great Lakes Region.
The deaths of the two males seemed to cause an increase in both daily
distance traveled and home range in Wolf No. 11. Essentially she began
traveling as extensively as do lone wolves in Minnesota (Mech and
Frenzel 1971).
The home range of Wolf No. 10 from March through mid-November, 346
square miles (895.7 km^2), was smaller than those of lone wolves in
Minnesota (Mech and Frenzel 1971). Apparently she was still expanding
her range when killed, however.
