The Ottawa Conservation District and partners are launching efforts to control and eradicate hemlock woolly adelgid (HWA), an invasive species now established in Michigan. HWA is an insect that targets hemlocks as their source of food. They can be found at the base of hemlock needles on the undersides of branches

Reminder – if you see trimmed hemlock branches while out for a walk, DO NOT MOVE them. Eastern hemlocks are under quarantine in Allegan, Muskegon, Oceana and Ottawa counties due to HWA. Moving branches with needles is illegal at this time, since it can spread HWA.
