Join Royal River Conservation Trust and the Gulf of Maine Research Institute (GMRI) for a free, hands-on workshop on the hemlock woolly adelgid (HWA) - an invasive pest threatening Maine’s hemlock forests.

HWA is a tiny, aphid-like insect that feeds on sap from hemlock branches, killing them over time. The insects cover themselves in a white, waxy secretion that looks like little cotton balls on the underside of needles.

GMRI will introduce Project Hemlock Woolly Adelgid, a community science initiative to monitor local forests. You’ll learn how to identify eastern hemlock trees, spot signs of HWA infestation, and report your findings. After an indoor introduction, we’ll head outside to Royal River Park to practice field identification and collect data together.
