BuzzH,
Nothing will happen until around September 1st. That is when the USFWS is suppose to announce whether or not they accepted Wyoming's plan. As you will recall, they are currently reviewing comments which were submitted until January 13, 2012.
The best the environmentalists can do is challenge the actions once it happens. Until then, they have nothing to do. Usually, they start with a 60 day notice of intent to file suit. As we learned in 2008 when wolves were first delisted and management authority was restored to Wyoming G&F Department, it takes about 30 days to transition from federal to state management. Given that, I would expect Wyoming will have about a 30 day wolf season, if nowhere else, at least within the predator zone. It is hard to say without a crystal ball, but I would imagine things should track pretty close to this out come. Hopefully, but doubtfully, environmentalists will allow the process to work. Wolves have met recovery goals, Wyoming's WMP ensures that wolves will be managed for long-term sustainability and will result in a maintained & sustained population.
Wish I could guarantee you were wrong but that is next to impossible. I just hope the USFWS and Secretary Salazar will honor their commitment to Wyoming. The track record for the USFWS is not very good here.
