Re: wrong focus
Gray and timber wolves are quite a bit different. Timbers are generally bigger and more aggressive than grays. They also have more color variation (minor point).
It is kind of a moot vote though. The Clinton administration got timber wolves introduced into Yellowstone park in the mid-90s (earlier than official documents show, btw) and those wolves have spread widely.
There were native wolves in Montana at that time (as well as northern Idaho and North Dakota and maybe more states but I can't testify to those). I scoped several while hunting the northern portions of Montana, Idaho and ND over the years between 85 and 95 before official introduction.
There was a case in Idaho where a hunter killed what he thought was a big coyote (which was legal). He turned it into Idaho Fish and Game where he was promptly given a ticket, fined and had his rifle and truck confiscated for killing a wolf. Eventually the courts declared that it couldn't be a wolf because legally the wolf was extinct in the US. This was right at the time the timber wolves were introduced into YNP. The wolf team denied it was one of theirs (because they insisted they knew where every one was and it would look dodgy if they acknowledged it was theirs). So either there were already wolves in the area, or the Fed wolf team was lying. Or both.
