Return of Wolves Changes Ecosystem

"Outside the fenced-off area near the river, considered a high-risk area for wolf attack, the amount of willows eaten dropped from 92 percent in 1998 to zero percent in 2002. There was little change around the fenced-off area in an open area away from the river identified as low-risk for wolf attacks." This is interesting because it suggests that the reintroduction of wolves could help repair riparian habitat.
