Exotic Invasive Species: The Guests That Won’t Go Home by Kim Cleary Sadler
In the continental United States, approximately 6-8 percent of species are introduced exotics.  In Canada, exotic species account for about 5 percent of mammal species and 27 percent of vascular plants.  Many are not harmful, but those that are pose a serious threat to biodiversity on this continent.  Kim Cleary Sadler examines the problem, looks closely at examples of exotic pest invasions such as purple loosestrife, zebra mussels, exotic tree fungi and non-native birds, and explains why educators should address this critical topic.
