USNPS bison biologist disputes new study claiming range damage in Yellowstone NP

A new report claiming that bison are damaging the Northern Range of Yellowstone National Park is drawing criticism from a park wildlife biologist who questions whether the scientists behind it are "looking too narrowly" at the range.

The study by Oregon State University researchers contends that bison "have become a barrier to ecosystem recovery in the iconic Lamar Valley." Bison, they say, have 10 times the impact elk have on the valley's vegetation.
