I agree cattle grazing is a huge culprit. I also think that introduced species should have as high of priority as natives. I love bull trout and Rockies. If I were to harvest fish, I would always harvest an introduced species before a native. So I'm on the opposite side as MK2720, because bull trout are amazing creatures and need the most help they can get. Along with grayling, athabows, and even mountain suckers.
