White rot fungi are among the few organisms capable of fully degrading lignin in wood.
Chaga infects birch trees through wounds in bark, often from storms or insects. Once established, it produces white rot that breaks down lignin, the structural polymer that gives wood rigidity. As lignin degrades, cellulose fibers remain but lose supportive strength. Over years, this internal decay reduces load-bearing capacity. The trunk may appear externally intact except for the visible conk. Under heavy wind or snow, weakened trees can fracture unexpectedly. The infection acts as a slow structural sabotage. One wound can eventually compromise an entire mature tree.

The transformation from living pillar to brittle structure unfolds invisibly. A tree that once supported tons of biomass becomes vulnerable to moderate weather events. In northern regions with heavy snow loads, this hidden weakening becomes critical. Entire sections of forest can experience sudden treefall during storms. The contrast between outward vitality and internal fragility is stark.
This dynamic influences forest architecture. Gaps created by snapped trunks allow sunlight to reach forest floors. Regeneration patterns shift accordingly. The fungus therefore shapes canopy structure through delayed mechanical failure. What begins as microscopic infection can end as a dramatic landscape change.
