Under Knowles, F&G  refused to protect the caribou herd adjacent to Denali Park from over predation of wolves. The Delta caribou herd went from 14,000 to 2500 in less than 3 years. All the while F&G refused to acknowledged what was happening right under their noses and what (wolves) was responsible for the dramatic decline even though many people gave them direct field reports in real time. The herd has not recovered to this day. It took 25 years of conservative management to get to 14,000 caribou and Knowles ruined it all. 

Buffer zone proponents refuse to acknowledge that all but one of the wolf packs in Denali are on the eastern park border for a reason. Their prey is on State land east of the park. That happens to be where game is actually managed. The only other pack is on the western park border. You guessed it. Adjacent to State managed lands. Ask yourself why the vast interior part of the Park with a huge no hunt, no manage policy has virtually no wildlife. Go figure!
