TRAVERSE CITY, Mich. (AP) – Scientists say the wolves of Isle

Wildlife biologists John Vucetich and Rolf Peterson of Michigan
Tech University say they counted 16 gray wolves on the Lake
Superior island this year – and just two at most are adult
The overall wolf population is the lowest since 1998, when it
Unless the females successfully raise pups before dying, the
entire population could disappear. Their plight raises the question
of whether the park should bring in more wolves.
The population has averaged about 23 since wolves migrated to
Isle Royale from the Canadian mainland in the late 1940s.
Scientists have studied their predator-prey relationship with
the island’s moose for more than a half-century.
