What is Lessoning Loosestrife?
Lessoning Loosestrife is curriculum designed for elementary - high school level students to help teach about wetlands, invasive species, and about using biocontrol beetles as a tool for controlling a wetland invader, purple loosestrife. Our aim is to not only teach lessons about loosestrife and key ecological concepts, but also to lessen the impact of this invader, while developing and reinforcing a stewardship ethic in students.
Who might find this curriculum useful?
These lessons are useful not only to those participating in or planning to begin biocontrol treatments of purple loosestrife infestations, but also to teachers who would like some simple, effective hands-on, inquiry based activities for exploring wetlands -- introducing the topic of invasive species and helping students develop an attitude of stewardship and community service in their classrooms. The curriculum is also useful to informal educators who may work with other audiences such as camps, after-school groups or home-school students.
The development of this standards-based curriculum was paid for by 5 Star Restoration Grant from the National Fish and Wildlife Foundation. It was developed by Liz Duff, Education Coordinator of Mass Audubon's Salt Marsh Science Project, in cooperation with Beth Suedmeyer, Restoration Planner for the Massachusetts Wetland Restoration Program.
