Ecological Dynamics on Yellowstone‚€™s Northern Range discusses the complex management challenges in Yellowstone National Park. Controversy over the National Park Service‚€™s approach of "natural regulation" has heightened in recent years because of changes in vegetation and other ecosystem components in Yellowstone's northern range. Natural regulation minimizes human impacts, including management intervention by the National Park Service, on the park ecosystem. Many have attributed these changes to increased size of elk and other ungulate herds.
