Is There an Ethical Way to Harvest Bark for Survival?

Choosing the Right Tree

When selecting a tree for bark harvesting, look for species that have a diameter of at least 10 inches and are not protected by local regulations. Some examples of suitable species include willow, cottonwood, and birch. Avoid trees with signs of disease or damage, as this can weaken the tree and make it more susceptible to further harm.

Proper Harvesting Techniques

To minimize damage to the tree, use a sharp knife or axe to carefully strip the bark in small sections, working from the bottom up. Remove only what is necessary for your immediate needs, leaving at least 50% of the bark intact to help protect the tree from disease and insects. For long strips, use a technique called “wounding,” where you create a small cut in the bark at the base of the strip, allowing the tree to seal off the wound more quickly.

Regeneration and Sustained Harvesting

A well-managed bark harvest can actually promote the regrowth of the tree, rather than causing harm. By removing only what is needed and leaving adequate time for regrowth, you can create a sustainable source of bark for survival purposes. In most cases, this means harvesting bark in the spring or fall, when the tree is dormant and less vulnerable to damage. This approach can also provide an opportunity to identify and manage any negative impacts on the ecosystem.
