Comparative effects of elk herbivory and 1988 fires on northern Yellowstone National Park grasslands
The drought, frequent lightning strikes, and resultant large fires of 1988 in Yellowstone National Park were considered a several-century event for the area. They presented an unparalleled opportunity to document the effects of large fires on forage…
