Invaders in Our Waters-Purple Loosestrife

Secondary

Description

The film introduces a success story in the use of biological controls to combat invasive species. In this case the invasive species is purple loosestrife and the biological control is a European leaf-eating beetle, Galerucella calmariensis. Students hearing  the story will learn how purple loosestrife threaten the biodiversity of wetlands and the reasons why biological controls in general and the beetles in this case are particularly effective.

General Assessment

Recommendation of how and where to use it

The video provides a case study in invasive species within the context of units dealing with biodiversity and ecosystems (Biology, Science, Environmental Science), resource management (Geography) and sustainable development.

This is one of a number of case studies found on the Ontario Invasive Species Awareness website. A cooperative learning approach may be used to have students investigate and report on a variety of invasive species within the curriculum opportunities identified above.

If the emphasis is on process, this program may be used to promote system thinking.
