Eastern Hemlocks are increasingly at risk from an invasive insect called hemlock woolly adelgid (HWA), an aphid-like insect that feeds by sucking sap from hemlocks. As our winters become warmer, these pests have been able to spread further north. Their feeding causes hemlock trees to lose their needles and stop producing new growth. Death of a tree typically occurs 4 to 10 years after infestation. HWA is currently present in many parts of Maine, including Lincoln County.
Property owners have a significant role to play in the control of HWA. In this recorded workshop, Education Director Sarah Gladu and Stewardship Director Brad Weigel of Coastal Rivers and entomologist Colleen Teerling of the Maine Forest Service discuss how to identify HWA, how to determine appropriate control measures, and what Coastal Rivers and other groups are doing throughout the region to protect hemlock trees.
