Citizens’ Guide to Invasive Aquatic Plant Management

Once an infestation has been confirmed, rabid MMI Guide Coverresponse is crucial. The prospects for effective management or even eradication is greatly increased by swift, well-planned, and properly executed controls. The purpose of the Maine Citizens’ Guide to Invasive Aquatic Plant Management is to provide the information necessary to effectively manage invasive aquatic plant (IAP) populations, to prepare for such an eventuality, and to address all associated activities. Methods described in this Guide are based upon tested best management practices for controlling aquatic plants effectively and in a manner that protects wildlife and habitat.


Friend or Foe? Learning Kit

Preventing the spread of invasive aquatic plants through education and boat inspections is essential to protecting Maine’s water resources. But 100% effectiveness is unlikely no matter how comprehensive the prevention effort. At some point, an invader is bound to slip through the cracks. It is very important for people who enjoy Maine’s lakes, ponds and rivers to learn how to recognize a suspicious plant when they see it, and know exactly what steps to take when they do. The Maine VLMP is pleased to offer this educational tool that teaches exactly that!

The Friend or Foe? Learning Kit has been designed to provide a quick, easy, hands-on method for teaching people with no previous plant identification experience how to quickly determine if a plant in question is a “friendly native” or a “suspected invader.” The Kit contains a collection of several true-to-form plastic plants (some representing invasive species, others, harmless natives), a set of 25 Quick Keys to Ruling Out Maine’s Eleven Most Unwanted Invasive Aquatic Plants, a self-guided practice sheet (that may be reproduced for students, or simply used by the instructor to guide the activity), and a host of other resource materials, including an instructor’s guide with background information and additional, hands-on invasive species lesson plans. At the conclusion of the exercise, it is recommended that participants keep their Key. (The handy, waterproof, pocket-folded keys may be re-ordered at low cost from VLMP.)

If you are interested in purchasing this kit, please contact the Maine VLMP at vlmp@mainevlmp.org or 207-783-7733.

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.
