Background
Maine’s Courtesy Boat Inspection (CBI) Program completed its 12th year in 2012. The purpose of these voluntary inspections is to reduce the spread of invasive aquatic plants (IAP) by boats, trailers, and associated equipment to Maine waters. Trained Courtesy Boat Inspectors discuss with boaters the risk posed by IAP, show boaters how to inspect and remove vegetation from boating and fishing equipment while urging them to inspect before and after every launch, and answer questions regarding IAP.
The Maine Department of Environmental Protection (DEP) contracted again with Lakes Environmental Association in Bridgton to train volunteers and organize the inspections in 2012.
