The presence of grizzlies and wolves in Montana, Wyoming and Idaho is considered a great conservation achievement that citizens should be proud of. Both species also are key attractions in a multi-billion-dollar annual nature tourism economy. Their value alive is exponentially greater than any costs they bring to the livestock industry, big game herds or wildlife management agencies. They are among the icons that also make Greater Yellowstone a bastion and bellwether for biodiversity. Photo courtesy Yellowstone National Park
