What Beech Bark Disease is
• Caused by a complex of beech scale and a species of Nectria fungi
• Develops in three stages • Advancing Front • Killing Front • Aftermath Zone
• Introduced from Europe in 1890 • Officially confirmed in Ontario in 1999 • Initiated by beech scale feeding • Final agent responsible is the Nectria fungus • Attacks larger trees first • Causes “Beech Snap” • 3-5 year mortally rate

Management Recommendations
• Hire a Certified Arborist to assess trees
• Fungus cannot be controlled only maintained
• Trees with poor vigor and visible cankers should be removed
• Water trees during dry spells
• Place wood chips around tree base
• Avoid root disruption
• Do not transport firewood from scale infested areas: between July-November
