Forest Health

A healthy forest is a productive forest

Maintaining a healthy forest is an important objective for most forestland owners. In this section, we provide resources to help answer questions about forest health, such as:

  • Are your trees healthy or not? How can you tell?
  • What are the most common tree health problems, and why do they occur?
  • How can you maintain healthy trees and prevent future problems?
