As is so often true, I'm a bit surprised just how many different types if Buttercups there are!
I found this article from England very interesting and its seems worth a read.

A few of the highlights:
1. The toxin may be higher or lower in different varieties, and once the forb is dried, it is no longer toxic, so if it is present in dried cut hay, this article claims it is not a problem.
2. It is more likely a problem in over grazed or low cut grass land, so rotational grazing and high mowing will help discourage it.
3. "Improving soil structure can also help to reduce buttercups as the majority like wetter anaerobic conditions..." Doesn't that just sound like my goal of increasing of the depth of my soil and its carbon content? However, it does seem to really like clay soil, and that's not going to miraculously change on my land!
This is a very interesting topic. Unfortunately, I'm not sure I've found the answer to the initial question, "what is its role?"
