Study confirms bison major factor in shaping vegetation at Yellowstone NP

MAMMOTH HOT SPRINGS, WY – Biologists from the National Park Service, U.S. Geological Survey, and the Universities of Wyoming and Montana published findings of a 10-year study about bison migration and grazing in Yellowstone National Park in the Proceedings of the National Academy of Sciences this week.


The findings result from a decade of research on Yellowstone bison by National Park Service biologists which included putting GPS collars on bison, setting up field experiments to evaluate plant growth and grazing intensity, and collecting dung and plant samples.
