i hadn't thought about that, makes total sense!
the notion i had was that the inverted version would represent the woodlots maintained by e.g. farming communities for timber or by nobles for hunting grounds, these being relatively small and surrounded by pasture and farmland , compared to the current version showing clearings surrounded by indefinite woodland
also, just want to say i think it's amazing how responsive you are to comments on all these generators, really appreciate it ! the generators themselves have been absolute godsends for my campaigns as well
