"Preserve Maine Waters" Stickers
Maine Department of Environmental Protection.
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.

Beech Leaf Disease Added to Maine's Invasive Species List (Jun 7, 2021)

Maine Department of Agriculture, Conservation & Foresty.

The Maine Department of Agriculture, Conservation and Forestry has announced an addition to the state's invasive species list. Beech leaf disease, leading to the decline and mortality of beech trees from Ohio to southern New England, has arrived in Maine's forests. The disease was confirmed in leaf samples from a forest in Lincolnville (Waldo County) by Dr. Robert Marra of the Connecticut Agricultural Experiment Station. The Maine Forest Service is asking the public's help in identifying additional areas impacted by beech leaf disease. If you suspect you have found affected leaves submit photos using the MFS tree ailment form, email foresthealth@maine.gov, or call (207) 287-2431. Photos should include a clear shot of the underside of an affected leaf or leaves. However, please report concerns even if photos cannot be provided.
