Alaska Paper Birch

Betula neoalaskana

Also known as Alaska Birch, Resin Birch

Alaska paper birch forms a defining canopy component across the vast northern boreal forest, thriving on cold, poorly drained soils underlain by permafrost. Young twigs are densely covered with prominent resinous warts that distinguish the tree from related birches, while mature trunks peel in delicate thin sheets of creamy white to pale reddish bark. In early spring, male catkins shed copious pollen on boreal breezes just before the triangular leaves unfold.

Responsible observation
  • Bark Identification: Check mature trunks for thin, peeling sheets of white to pale copper bark.
  • Twig Inspection: Look closely at young shoots for raised, rough resin glands that feel bumpy.
  • Boreal Etiquette: Avoid stripping bark from living trees, as peeling exposes the wood to fatal decay.
