Permaforestry is an approach to the wildcrafting and harvesting of the forest biomass that uses cultivation to improve the natural harmonious systems. It is a relationship of interdependence between humans and the natural systems in which the amount of biomass available from the forest increases with the health of its natural systems.
Examples of bioproducts derived from biomass created through permaforestry include: honey, maple syrup and other tree saps, gourmet foods, functional foods, berries, wild mushrooms, acorns, walnuts, mockernut, pignut hickory, ginseng, wild rice, herbs, fiddleheads, extracting pinenuts from pinecones, fish, frogs and crustaceans, deer, moose, brought over wild boar (to the Americas), partridge, grouse, free living turkey, Canada geese and co.
