Don grasslands need to be grazed to be healthy?
No. Most of the interior West, where the majority of public lands are found, did not evolve with large herbivores like bison. As a result, they are poorly adapted to tolerate domestic livestock grazing. On the Great Plains, where plant communities are more tolerant of herbivory pressure, there are relatively few acres of public land, and no shortage of private land that are grazed. In addition, grazing by domestic livestock and wild bison on these grasslands are not comparable.
