This program gives students a practical application of invasive species management focusing on Purple Loosestrife. Students assess the plant diversity in an infested wetland, raise and apply beetles in a marsh as a control agent, and monitor the results.

As the title indicates, this practical, action-based program focuses on the interactions of a single exotic invasive, purple loosestrife, with its wetland habitat and beetles which can control its density. Along the way, mostly through research, reading and question-based discussions, participants learn about the value of, and threats to, wetlands, current wetland status in the United States, the costs and benefits of various control options (including doing nothing), and the efficacy of biological control agents. Good questions and sample answers are provided; questions on leader summary sheets are excellent and should be worked into activity introductions and conclusions. On the discovery-based side, students assess the plant diversity in an infested wetland, raise and apply beetles in a marsh as a control agent, and monitor the results. Participant workbooks provide a coherent record of the program to take away. The program is designed for students in grades 9-12 and is linked to national standards. The programís 4-H orientation however, somewhat limits the assessment of student outcomes. For a more classroom-based approach, see the companion program, Purple Loosestrife Project 6-12.
