Invasive Species Dodge Ball
By Kim Fulton
The main purpose of Invasive Species Dodge Ball is to illustrate how quickly invasive species can change ecosystems forever. It is also an exciting way to stimulate conversation and interest in a study of ecosystems and invasive species. In British Columbia, where I live, spiny ray fishes such as perch and bass are a threat to our aquatic ecosystems in which salmon and trout thrive. Zebra mussels, quagga mussels, and invasive aquatic plants are current threats to ecosystems. People in areas where perch and bass are popular game fish will want to choose other species. Asian Carp, goldfish, snakehead fish may be good choices. However, make sure you choose local invasives to make it relevant for your students.
