Invasive Species

Invasive species are species that somehow are out of balance with nature.  Most often they are species that have been moved from their original ecosystem to another ecosystem because it was thought to be useful in some way.  Often the species have crossed oceans to get to where they are currently a problem.  Whenever we bring in species from another continent we are setting ourselves up for potential problems.  In Southern Illinois the list is long as you can see from this publication by Heartland Conservancy in Mascoutah, IL
