Prevention

With over 6000 lakes and ponds, and thousands of miles of stream habitat, the task of preventing the spread of invasive aquatic species in Maine waters is one of the greatest environmental challenges of our time. Invasive plants and animals are moved about in complex and often unseen ways. The speed at which a new introduction can explode into an ecologically and economically disastrous infestation is well documented. Once an invader is well established, eradication is extremely difficult and costly, if not impossible.

Courtesy Boat Inspections

The Maine Department of Environmental Protection (DEP) oversees Maine’s Courtesy Boat Inspection (CBI) program and distributes funding to organizations trying to protect lakes. While DEP provides training, protocol, and funding, none of this prevention work can be done without the hard work of local residents.

Courtesy Boat Inspectors:

• Discuss with boaters how invasive aquatic plants spread
• Show boaters how to inspect boats and equipment for plant fragments
• Urge boaters to inspect before and after every launch
• Distribute information about invasive plants
• Articulate Maine law regarding the transport of these plants

Every year Maine CBIs conduct thousands of boat inspections and intercept hundreds of plants entering and leaving Maine waters. Click here for the most recent CBI statistics. Also see In a Nutshell: How to be a great CBI.

Training for the Courtesy Boat Inspection program is funded through the Maine Lake and River Protection Sticker program, and is coordinated by Lakes Environmental Association in partnership with the Maine Lakes Society and the VLMP.

CBI training is now available through the Maine Volunteer Lake Monitoring Program! As of 2014, a CBI workshop option is available to communities who are hosting an Invasive Plant Patrol (IPP) Field Workshop. Trainees at these combined workshops will have the option of attending one portion of the workshop or both. Please see the IPP workshop schedule to find IPP/CBI combined workshops in your area.

Prevention Guidelines for Seaplanes

Many aquatic nuisance species (ANS), such as the zebra mussel and Eurasian water-milfoil, can be unintentionally transported from one waterbody to another on the floats of seaplanes. Therefore, it is important to clean the aircraft to remove ANS before traveling, rather than after landing at new locations. In addition, it is important for you to incorporate the procedures listed here into the operation of your seaplane. However, plane safety is the first priority when considering and following these guidelines. Please click here for US Coast Guard Guidelines for Seaplanes.

Our Mission

The Mission of the Maine Volunteer Lake Monitoring Program is to help protect Maine lakes through widespread citizen participation in the gathering and dissemination of credible scientific information pertaining to lake health. The VLMP trains, certifies and provides technical support to hundreds of volunteers who monitor a wide range of indicators of water quality, assess watershed health and function, and screen lakes for invasive aquatic plants and animals. In addition to being the primary source of lake data in the State of Maine, VLMP volunteers benefit their local lakes by playing key stewardship and leadership roles in their communities.

The VLMP is a non-profit 501(c)(3) organization committed to the collection of information pertaining to lake water quality. For 40 years, trained volunteers throughout Maine have donated their time so that we may all learn more about one of Maine’s most beautiful and important resources — our lakes.
