"Perennial Pathways: Planting Tree Crops - Designing and Installing Farm Scale Edible Agroforestry" (Mat Wilson, Sarah Taylor Lovell, & Tobias Carterm 2018) is an interesting resource published by Savanna Institute in the United States. Visit the website to download your copy at http://www.savannainstitute.org/ From the Forward:

Mat Wilson, lead author of this excellent book, has a knack for finding where the wild meets the practical. I first heard from him when he was plotting out persimmon, mulberry, and chestnut silvopasture paddocks, with fruit drop planned in sequence for livestock to harvest through several rotations each season. This book is filled with these sorts of wildly practical ways to integrate perennial crops on your farm.
