RE: wolves
The wolves they reintroduced aren't even the wolves that were native to this area. The reintroduced wolves have no doubt killed off the remaining native wolves. So even if we were to kill off every one of the vermin we would only be eliminating a non-native species from the ecosystem. I personally don't have a problem with wolves in Wyoming if they let us control their poplution numbers. They're a neat animal and they can serve a purpose in the ecosystem in some areas. They just need to be thinned out a bit (or a lot) before they really screw up elk, moose, and bighorn sheep herds.
As far as how many have been killed, the official reported number was 10 as of today. There are reports of another two unconfirmed kills. All 10 knows kills were in Sublette County. USDA agents also killed another 4 yesterday near the trophy area boundry after they got into a rancher's pen and four or five calves. They had a permit to kill the wolves in the trophy zone, but they ended up finding and killing them in the predator zone.
