I agree that some of the "reintroductions" are getting out of hand.  It seems like the successful reintroductions have been with big game animals like elk, moose, and bighorn sheep.  And the unsuccessful reintroductions were with preditors.  There are more opportunities to hunt these animals today than there were 100 yrs ago.  And others like Oryx and Ibex in New Mexico and the many Exotic animals found in Texas and a few other states are huntable there and not in their native countries.

The reintroduction of wolves to the northern Rockies is perhaps the biggest disaster in wildlife management in the last 100 years.  As hunters and ranchers, we will be suffering from that mistake for many years.

I heard that several years ago, the Colorado Dept of Wildlife reintroduced Lynx in Colorado, and I later heard that they all died.  A great waste of sportsmen's dollars and of the Lynx that they sacrificed for their little experiment.

Wolverines are a very secretitive animal that have a very large home range.  Often they will travel in the hundreds of miles in a single year.

Very often, the biggest problem with these reintroductions, is the restrictions the wildlife agencies put on the existing human population and like in the case of the wolves, there is not a definative process for ending the restrictions once the introduced animal is established.

I've only seen two wolverines in the wild.  One was in a  SW Montana wilderness while I was hunting bighorn sheep, and the other was in the Mackenzie Mountains in Canada while I was hunting Dall sheep.  Here's the one from Canada.
