There aren't too many wolverines anywhere they live. Let's do the math:
Most biological surveys, including those in the far north, estimate 5-15 wolverines per 1000 square kilometers. (1000km2=386 square miles.) That's not a lot of animals, but the country they inhabit has very low biological productivity, because it's either high in elevation or very far north, and wolverines reproduce slowly.
Only the western third of Montana has any wolverines, and 1/3 of Montana is about 50,000 square miles. At most about 1/4 of that 50,000 (12,500 square miles) is the real wilderness where wolverines can live. Given 5-15 wolverines per 386 square miles, that means about 162-486 wolverines, an average of 324. Which may or may not be where the Montana game department got their estimate.
