Hemlock Woolly Adelgid (HWA) is an invasive, sap-feeding insect that has caused extensive hemlock mortality south of New Hampshire. Now, it’s threatening hemlock forests in the Granite State too. Join forest health specialist Ryan Crandall to learn about the origins of HWA in the United States, the history of the HWA biological control program, and options for chemical and silvicultural control. We’ll also discuss the potential release of predatory beetles to combat HWA on select Harris Center properties.

7 to 8:30 p.m. at the Harris Center. Space is limited, and registration is required. For more information, including questions about accessibility, contact Eric Masterson.
