I believe it was because of the prevalence of prairie fires. Killed the trees, but the grasses loved it.

My home state, Nebraska, was originally pretty much devoid of trees, except along the river bottoms. But they have planted millions of them over the last century and a half. They do fine without the naturally-occurring prairie fires to take them out.

That’s what I was thinking. If we can grow trees hydroponically, certainly the Midwest can do it conventionally.
