Bison eradication stripped western grasslands of nutrients, Yellowstone research shows
August 29, 2025/
Free-roaming herds of large herbivores are few and far between on Earth, but where they do occur — like with bison in northwest Wyoming — monitoring shows a remarkable bump in grassland nutrition.
“There are spots that bison hit hard, and places they don’t touch at all — and that can change over the years,” he said. “The cool thing is that allowing these bison to freely move across the landscape at a big scale, creates the heterogeneity.”
