What are invasive species?

Invasive species are non-native plants, animals, or pathogens that harm natural areas. They can cost millions of dollars to control and hinder outdoor activities such as fishing, hiking and birding. Aquatic invaders such as silver carp pose a major ecological and safety threat to Illinois waterways.
