Field and Stream magazine has an articel up on the impact wolves are having on deer populations in this corner of the country. Short version: Mountain lions and coyotes take far more deer than wolves, but the effects of all three are dwarfed by the impact of the weather. The North Fork gets a specific mention in the discussion . . .
In 2011, for the first time ever in Idaho, hunters harvested fewer mule deer than whitetails–big news for a state with a deer harvest that has long been dominated by muleys, and whose recent-big game headlines have been dominated by wolves and stories of their impacts (some exaggerated, some true). Wolf kills, scat, howls, and tracks… are frequent reminders of wolves’ presence in the Western whitetail woods.
