Young wolverine makes 500-mile trip to Colorado – The Denver Post

A wolverine has traveled more than 500 miles from Grand Teton National Park into Colorado, the first known incidence of a wolverine in Colorado since 1919, wildlife officials said today. …

The wolverine, a young male known as M56, spent April and May traveling 500 miles south from Grand Teton National Park and successfully crossed numerous highways, including Interstate 80 in southern Wyoming, to reach Colorado.

The wolverine, which was collared in December, is now in northern Colorado, where the Colorado Division of Wildlife and the Wildlife Conservation Society are jointly tracking it.

Bob Inman — the Ennis, Mont.-based director of the Greater Yellowstone Wolverine Program — said wolverines were virtually wiped out in the lower 48 states by 1930. They were killed by unregulated trapping and poison-baited gut piles, he said. There has been a very slow recovery with about 250 believed to be living in the lower 48, said Inman.
