Symposium on Hemlock Woolly Adelgid in the Eastern United States
The introduced hemlock woolly adelgid (HWA), Adelges tsugae, continues to migrate north into New England, causing widespread hemlock decline and mortality, and an increase in hemlock removal. This outbreak has led to management dilemmas about pre-salvage and salvage logging in hemlock stands: should they be cut down or not? Regardless of the decision made, there is a critical need to review the available options and clearly determine the appropriate goals first, especially if HWA has not reached your forest yet. Although there are various chemical and biological control options for HWA that are effective in ornamental situations, they are not practical or effective at larger scales of stands to landscapes. This paper describes silvicultural options available to help landowners manage their hemlock forests infested with or threatened by HWA.
