Stacking Cordwood Between Trees: Insect/Disease Bridge Risk

Wood Pile as Pest Highway

Cordwood itself doesn't kill trees. But:

• Pine bark beetles in pine logs → emerge, attack standing pines.
• Oak wilt fungus in oak logs → spreads to healthy oaks via root grafts or beetles.
• Hardwood logs: lower risk (most borers only attack dead wood).

Stack wood away from live trees of same species. Keep pile dry, covered.
