Interesting article: https://www.pnas.org/doi/10.1073/pnas.2210433119
I got hit with a pay wall, but here is the abstract:
What I'm reading here is that Bison are a critical part of the American ecosystem, cattle also help with richness but not to the same level as the Bison.
Now, let's not get into a debate about climate change, but this poses an interesting idea. Could bison reintroduction play a key part in combating future changes, specifically droughts that are becoming more common? Ranchers will never want to go that route for many reasons, but that's a pretty elegant part of a solution IMO.

Abstract
The widespread extirpation of megafauna may have destabilized ecosystems and altered biodiversity globally. Most megafauna extinctions occurred before the modern record, leaving it unclear how their loss impacts current biodiversity. We report the long-term effects of reintroducing plains bison (Bison bison) in a tallgrass prairie versus two land uses that commonly occur in many North American grasslands: 1) no grazing and 2) intensive growing-season grazing by domesticated cattle (Bos taurus). Compared to ungrazed areas, reintroducing bison increased native plant species richness by 103% at local scales (10 m2) and 86% at the catchment scale. Gains in richness continued for 29 y and were resilient to the most extreme drought in four decades. These gains are now among the largest recorded increases in species richness due to grazing in grasslands globally. Grazing by domestic cattle also increased native plant species richness, but by less than half as much as bison. This study indicates that some ecosystems maintain a latent potential for increased native plant species richness following the reintroduction of native herbivores, which was unmatched by domesticated grazers. Native-grazer gains in richness were resilient to an extreme drought, a pressure likely to become more common under future global environmental change.What I'm reading here is that Bison are a critical part of the American ecosystem, cattle also help with richness but not to the same level as the Bison.
