Evidence

Peer-reviewed

Geography

Badlands and Theodore Roosevelt National Parks and neighboring US national grasslands

System

Mixed-grass prairie; native grazer reintroduction

## WHAT THE EVIDENCE SAYS

Comparing bison-occupied national park plots with nearby cattle-grazed grasslands, Noble and Ratajczak detected no consistent plant-diversity benefit from bison. One site had lower diversity where bison occurred, potentially influenced by invasive Bromus; heavier woody encroachment reduced diversity across sites.

## WHY IT MATTERS / OUR READ

Restoring the native grazer is ecologically meaningful but not a substitute for measuring plant-community outcomes, encroachment and invasive vegetation.

## CAVEATS / UNCERTAINTY

Observational, site-specific park-versus-grassland comparisons cannot isolate grazing identity from management history. First published January 2026, newly covered here.
