Common Pests That Threaten Trees
- Emerald Ash Borer: A beetle that targets ash trees, causing canopy dieback and bark damage.

Managing and Preventing Pest Damage
Effective pest management involves a combination of monitoring, cultural practices, and treatment options:
- Regular Inspection: Check your trees frequently for early signs of pests.
