i am trying to find a book on how to grow nativewild edibles in a natural setting such as forests and every type of edible plant native to the right region. does anyone know of such a big book? i already found The Forager's Harvest but need more info on this topic.
Here's a link to the North American Native Plant Society's resource page for "other publications", i.e. those not published by the NANPS itself. I don't think you are going to find one book that's going to fulfill all that you seem to be looking for, simply because something that exhaustive would be huge - North America has so many different climates and ecologies. I would suggest talking to your local Cooperative Extension, often they have information on resource management that includes the protection and encouragement of native species. And some of the books I linked to look very interesting, as well.
I don't think you are going to find what you want in one big compendium. But you may find all the pieces for it online. The Alternative Field Crops Manual from Purdue university has a good selection of crops to start with.
And "every type of edible plant native to the right region"? That covers and enormous number of plants! Are you planning to start with your own region and branch out from there? If so, ethnobotany, i.e., what did the indigenous people eat, both cultivated foods and stuff they gathered, would be a place to start.
Dave Jacke's Edible Forest Garden Volume 2 is an excellent resource. It has an appendix with everything you need to know about many plants. It's used as a text book in classes. If I had to own just one book for permaculture this is the obvious choice. (I've never read the first volume though.)
The Forager's Harvest and Nature's Harvest by Samuel Thayer are far from exhaustive but they do have a good amount of information ranging from habitat/preferred growing conditions to harvesting and preparing.
