This August, an ACE Arizona chainsaw crew worked to remove the spruce bark beetle (Dendroctonus rufipennis) from Flagstaff’s backyard ski area, Arizona Snowbowl. Crew leader Shelby Descamps provided excellent leadership to the ACE crew for two, eight-day projects.
The spruce beetle has caused extensive tree damage to all species of spruce throughout the West. In order to deposit their eggs, female bark beetles bore into the bark of dead or dying spruce trees and lay eggs in the underlying phloem tissue. While these beetles are a natural part of the ecosystem, inhabiting dead or dying trees, they often become overpopulated and infect living trees as well. A combination of natural factors that impact forest health such as drought, dense forest stands, fire suppression, and past grazing practices contribute to conditions that foster bark beetle outbreaks. In the past 25 years, outbreaks have resulted in estimated losses over 100 million acres in Arizona (U.S. Department of Agriculture and Forest Service).
In attempt to prevent future tree loss, ACE partnered with the Arizona Snowbowl to remove the bark from fallen and dead trees to remove the larva. With a log debarker attachment for chainsaws, crewmembers were able to peel off the bark and remove the larva. ACE is proud to be working in the Flagstaff community to help preserve the spruce population.
