Hemlock wooly adelgid is a small insect that drains sap from hemlock branches until the tree dies. Until recently, cold winters have limited the spread of hemlock woolly adelgid. As winter temperatures warm, scientists and resource managers suspect this pest could spread throughout our region. Join Wolfe's Neck Center and Gulf of Maine Research Institute staff at the farm and learn how to identify and monitor Eastern hemlock trees for these invasive insects and submit critical data to an ongoing community science project.
