books that cover morphing an existing forest into a food forest

Can anyone recommend a book that covers the issues of integrating food plants into an existing semi-natural forest? We've got a large area of Doug Fir and declining Cedars, but also some edge areas with a mix of some variety of Service berry, Ocean Spray, Gary Oak and a sprinkle of Doug Firs.

I suppose I should mention that there are a *lot* of rocks also. I've tried planting into existing areas but have had pretty much a zero survival rate with mostly the STUN method. (Granted this year's drought was exceptionally bad and plants that were just hanging on appear to have succumbed. )

This year I've had Hubby pull out a bunch of the Ocean Spray and dug a couple of compost pits and my plan is to transplant trees where they can access the moisture plume of one the pits.

I have not read this book, but I found a mention of it on a Reddit site:

Farming the Woods

and there is a website too: https://farmingthewoods.com/

hope this helps :)

Thanks Lana! My library system even has copies of it, although there's a short wait list. Hopefully I'll get some ideas from it.
