Natural Diversity

[KevinTheCynic]

As an afterthought, it's worth mentioning that if you have crop fields or orchards with no open land around them, you won't get any wilding plants from those fields/orchards. For example I have a crop field that is bordered by other fields and by a river and a stream and none of the plants from that particular field have been able to "cross the border" and take advantage of the Rebellious Crops mechanic and escape into the wild - because there is no open land for them to escape to!
