Provides an assessment of the ecological history of Yellowstone's northern range, showing the impact of US Park Service policies on the health of the areas they oversee. This book shows that elk had been historically rare throughout the region and that overgrazing by elk has seriously degraded the landscape and altered the structure of the area.
