Invasive Plant Patrol 101 ~ Online Course
Part 3 – Aquatic Plant ID
Participation in this course is required for anyone wishing to receive IPP certification

LSM’s Invasive Plant Patrol 101 online 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 receive IPP certification must take (and pass) the short online quiz at the conclusion of each course section. The quizzes are optional for all others.
