I really like this idea and have always loved the idea of growing food in a “food forest” way or, you know, how stuff grows naturally 🙃
I’ll be honest though, I didn’t realize there were a specific “7 layers” and feel your additions just make sense. We as humans can make a beautiful food forest but leaving out the non living things you have mentioned here means we still are interfering in a way.
Clearly some things won’t work for some that will work for others, but I think habitats that welcome beneficial animals and decaying logs/stumps that just add beneficial nutrients to the soil are well, beneficial.
Thanks for this right up, your blog is very well done!
