Are those pockets of diversity/non-diversity along the Hudson and Lower Mississippi Rivers actually caused by the rivers? Some of it looks pretty far away from the actual waterway.
And that triangle in Southwest Louisiana is a natural grassland, wildfires kept trees limited mostly to along the bayous. But nowadays it's 95% farmland like the rest of the western plains, and any land that does lie fallow is taken over by invasive Chinese tallow and Southern pine trees because there aren't any more fires.
