I live in Minnesota, where a good portion of the forests have been absolutely ruined by buckthorn. It changes what should be fairly open woods with large trees to something you literally can't walk or see through. In my experience it also gives cover to mosquitoes, protecting them from predators. If I were a billionaire I'd fund research to create some sort of Dutch-elm like disease for it and release it in secret.
