The ins and outs of how to harvest birch bark from living birch trees. John Zasada, an experienced birch bark harvester and weaver, discusses what kind of trees to look for, how to harvest the bark, how much and how often you can harvest from a tree, how to store your birch bark properly and a bonus on how to make cookies from birch bark flour. One thing John forgot to mention about the cookie making process is that the inner bark needs to go through a series of water baths/extractions to remove most of the tannin from the inner bark. Without this the inner bark flour can not be used.
