In late September, nearly 100 arborists and other tree professionals met in Asheville, N.C., to discuss ways the industry can join together to address the devastating Hemlock Woolly Adelgid (HWA).
This meeting's objectives included:
- Summarize the latest research regarding the use of neonicotinoid insecticides for control of HWA
- Propose a near-term management plan for HWA affecting high value hemlock stands and individual trees.
- Highlight a documentary that is being developed to raise awareness of the HWA crisis: "The Vanishing Hemlock: A Race Against Time".
- Identify obstacles that are preventing more aggressive treatment of hemlocks
- Tour first hand a forested area that has been heavily impacted by HWA
- Motivate interested parties to collaborate in the effort to preserve as many hemlocks as possible from HWA
