Interactive Field Guide
Identify plants using the online interactive Field Guide to Maine’s Aquatic Invaders.
Aquatic Species Identification Cards (a set of sixteen 3.5″ x 4.5″ full color, waterproof plastic plant ID cards) are now available from the LSM at $12.00 per set. To order, please contact email@example.com.
The cards feature photos and concise descriptions for the five invasive aquatic plant species known to be in Maine as well as twenty-four of Maine’s more common native aquatic plants. Cards are color coded (red for invasive, green for native) to help you tell the good plants from the bad. The set is bound by a binder ring and hung on a carabiner, so you can hook them to your belt-loop or swimsuit strap and go! The set can also be easily expanded as new cards become available.
Please note: This set currently only includes five of the eleven plants on Maine’s prohibited list.
The Field Guide focuses on the eleven invasive aquatic plants currently listed by Maine law as imminent threats to Maine waters. Also featured are many native aquatic plants commonly confused with these eleven invasive species.
Photographs, illustrations and narrative descriptions are presented for each of the featured species, along with a variety of cross-reference tools for easy comparison of similar species.
This 160-page reference–spiral bound and printed on tear-resistant waterproof paper–is built to hold up well to conditions in the field (including inclement weather and the occasional dunking).
Free Field Guides for LSM Monitors: One complimentary copy per volunteer.

Citizens’ Guide to Invasive Aquatic Plant Management
Once an infestation has been confirmed, rabid response 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.
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 LSM 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 LSM.)
If you are interested in purchasing this kit, please contact the LSM at email@example.com or 207-783-7733.
