Invasive Plant Patrol Workshops

Greetings Invasive Plant Patrollers!

LSM provided training and informational sessions in an online format in 2020 due to the CoViD-19 outbreak. Online trainings from both 2020 and this year were recorded and links are provided below for your viewing at a convenient time. Events as part of our current summer season are posted below and additional postings will be made all summer long.

How to Lead an Invasive Plant Paddle

Plant Paddles are guided explorations that take place on shore and on the water. They are a fun, informal way to learn about Maine’s native aquatic plants, as well as the invasive aquatic plants that threaten Maine waters. In this live webinar, Roberta Hill will provide you with everything you need to know about leading a plant paddle on your favorite waterbody. This webinar is open to all and should be especially valuable to those of you who wish to activate (or reinvigorate) an Invasive Plant Patrol team on your lake! There will be plenty of time for questions, answers, and for sharing ideas.

Invasive Plant Patrol 101 ~ Online Certification Course

Invasive Plant Patrol 101 (LSM’s IPP certification course) is comprised of three parts:

      • Part 1 provides a general introduction to the threat of aquatic invaders; 
      • Part 2 provides guidance for conducting an invasive plant screening survey, including discussion of tools and techniques;  
      • Part 3 takes a deep dive into Aquatic Plant ID with a focus on the eleven invasive aquatic plants considered to be most imminent threats to our state, and their native look-a-likes.

Participants who wish to become LSM Certified Invasive Plant Patrollers must pass a short online quiz at the conclusion of each course section. The quiz is optional for all others.

In the final stage of certification, participants are asked to collect several aquatic plants on their own, and then attend one of LSM’s regularly scheduled Plant ID Zoom Sessions (schedule and registration below) for feedback on tentative ID’s and/or guided identification.
