Maine Field Guide to Invasive Aquatic Plants
and their common native look alikes
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 VLMP Monitors: One complimentary copy per volunteer.

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 Center for Invasive Aquatic Plants (MCIAP) announces a unique new educational tool that teaches exactly that! It will be available for a select number of schools, lake associations, civic clubs and other pilot groups in fall of 2005.

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 reordered at low cost from CIAP.)
A limited number of kits will be ready for testing by schools and other pilot groups in the fall of 2005. If you are interested in participating in the pilot program, please contact the Maine Center for Invasive Aquatic Plants at vlmp@mainevlmp.org or 207-783-7733. Feedback from all pilot groups will help to refine the “final product.” For those who do not make it into the 2005 pilot program, please stay tuned . . . CIAP plans to shift the Friend or Foe? Learning Kits into full-scale production next year!

Invasive Plant Patrol Monitor Certification 
The goal of the IPP Certification Program is to encourage and support individual and group commitment to annual collection and submission of invasive aquatic plant screening survey data. To become a Certified Plant Patroller you must have participated in at least one Introductory IPP workshop (or equivalent training), complete the questionnaire (only the portions that apply) and sign the statement of commitment. The VLMP Center for Invasive Aquatic Plants will provide all certified patrollers with standardized field sheets, and an ID card.
