I'm sure people will chime in to help. I'll just tell you where I would start. I would plant windbreak trees on all sides except the south. I think it was
Gaia's Garden where I first read about how important windbreaks are, and how much they improve your forest garden's productivity. I would have to look for sure. I would recommend getting windbreak tree and shrubs in first. You can start those now while everything else is still in the planning stage.
The other recommendation I would give you is to be very careful with tree spacing. Everyone I know, and yes, that definitely includes me, puts way too many trees in in the beginning. It's very hard not to. At first, your forest garden looks like a big field with a few sticks in it. As hard as it is to do, try to live with that tree spacing for a few years unless you plan to cull trees heavily. In the end, you want trees with lots of support species and layers, but still an open
canopy. If I were starting over, I would recommend figuring out what you think you would like your tree spacing to be, and then at least double it. You can always add more trees, but it can be painful to cut down a tree you spent years growing because you put everything too close together.
