In 2008, the purchase of a new sticker for owners of Maine-registered watercraft was automatically combined with the watercraft registration fee. The sticker, which now reads "Stop Aquatic Hitchhikers -- Preserve Maine Waters" and is physically attached to the Maine watercraft registration, has been required since 2002 for all motorized watercraft on inland waters. Owners of non-Maine registered boats will continue to be required to purchase and affix a separate nonresident sticker.

The emerald ash borer (EAB), Agrilus planipennis, is one of the most serious invasive species threatening our ash resources and forests. All species of ash that grow in Maine are susceptible to injury and death by the emerald ash borer. As of September 2018, EAB has been found in Aroostook Co. (Madawaska, Frenchville, and Grand Isle), and York Co. (Acton and Lebanon), ME. If you suspect emerald ash borer, please report it online, or call: 207-287-3891.

Maine Forest Service. Winter moth was first recorded in Nova Scotia in the 1930s and then in the Pacific Northwest in the 1970's. It showed up in eastern Massachusetts in the early 2000's and has since spread into coastal Maine from Kittery to Bar Harbor. Fill out the Winter Moth Survey to help us gather information about the distribution of these moths across Maine. The results will be used to help with biological control development and other research.
