Ice‑Damaged River Birch: When to Remove a Broken Trunk

Assessing the Damage

A four‑trunk river birch lost one trunk (broken at 5–6″ diameter) and bent another to the ground. The broken trunk carried ~50% of the foliage, mostly larger lower branches.

Why Removal Is Advised

Foliage loss >25% triggers epicormic sprouts (water sprouts) and weakens the tree.
River birch compartmentalizes decay poorly (CODIT rating weak). A large wound at the break invites rot.
The remaining three trunks can sustain the tree.

Cut the broken trunk at ground level. The tree will look better and avoid future hazard.
