Oh, that is really cute. It actually reminds me of my grandfather's place. He kept a small tomato farm on the edge of his property. ^_^
I have a riverland farm and I'm clearing and using it island by island. I currently have half of the main island and the one directly below cleared.It also works on the other maps, just section of whatever you want to use and ignore the rest.
Large parts of my farm are usually a forest because I'm lazy.
