Free Bark Beetle Site Assessments

Shared from AZDFFMThe Arizona Department of Forestry and Fire Management's Forest Health team is currently scheduling free site assessments for property owners who believe they may have bark beetle presence/damage to their trees (available in English and Spanish). The invasive Mediterranean Pine Engraver is well established in the Phoenix and Tucson urban areas, and many other locations around the state - with most recent new findings confirmed in Sedona and Cottonwood. The winter months are the best time to take action when the bark beetles are most likely to be dormant. Email foresthealth@dffm.az.gov to schedule your free assessment.
