In another thread (
https://permies.com/permaculture-forums/690_0/permaculture/poplar-trees ), you listed some shrubs, that were more compatible than lawn for my poplar trees, by species.
This got me wondering, does your book cover plants that are local to particular regions?
I live near Cape Cod in Massachusetts and one strange thing that happens on the cape is for people to visit, fall in love with the area, move there, and then immediately start replacing the natural plant life (par of what they fell in love with) with the things that are native to their hometowns. Lawns are actually an un-natural phenomenon here. I know this is a big issue in Arizona as well. Obviously the book would need to be very thick to get into specific species for every area but are there any guidelines or generalizations for people to use when looking up local substitutes for plant types that you recommend?
