Is it buttercups or "snakeweed"/"bitterweed"
When I see them I think overgrazed land.
I watched many a pasture along I-40 go to that natural (or unntural) progression over the years
I thought that was the cause also, but then I've also seen it grow in pastures that were thick and not hardly grazed. But, from what I can understand, it does grow faster in pastures that are overgrazed.
