A Kansas State University-led study has found that reintroducing bison doubles plant diversity in a tallgrass prairie. The research involves more than 30 years of KNZ LTER data and was recently published in PNAS.

The research team was lead by KNZ LTER investigator Zak Ratajczak. Other KNZ LTER researchers included Jesse Nippert, John Blair, Allison Louthan, Scott Collins, Sally Koerner, Melinda Smith, and Jeff Taylor.
