One of my permaculture teachers was recently interviewed on this radio program.  You can listen to it here: Food Forests Across America.

What I liked most was their visionary description of a forest garden – not reduced to its definition – but as a guided journey:

“Imagine a forest where every single tree is dripping with fresh fruits and ripening nuts. Every shrub is packed with delicious berries, and every other plant is a medicinal herb, culinary spice, or beautiful edible flower. Tubers and root crops are abundant underfoot, gourmet mushroom logs sprout in the shade, and hardy kiwi vines climb back up through the layers of this multi-functional forest of food.”
