Rare sighting of wolverine outside usual range after 30 years.

A wolverine, classified as a threatened species in Oregon, has been spotted outside its usual roaming range for the first time in over 30 years near Portland. The animal was likely dispersing as the habitat in the area doesn't meet the life history requirements of wolverines. Wolverines are mostly found in Alaska and Canada, but have populations in Oregon, Wyoming, Montana, Washington and Idaho. Conservationists are trying to cross-reference other wolverine genetic samples to see where it came from.
