Harvesting Birch Bark: Sustainable Practices

Buying Birch Bark Skins: Impact on Trees

From a lumber yard? Likely from logged trees—no harm to standing forests.

Safe: Peeling loose outer bark from paper birch (Betula papyrifera) doesn't harm the tree.
Deadly: Cutting into green cambium layer all around trunk = girdling = death.

Pruning live branches is fine if ≤1/3–1/2 of canopy remains. Dead branches: no limit.
