Grazing by non‐native ungulates negatively impacts vegetation important to a native species of concern

Ecosphere
Non‐native grazers compete with native species across the globe. We present a novel approach to study the composition of the herbaceous understory across three study areas within the Great‐Basin with different historic and contemporary grazing regimes ...
