Invasive plants and animals are species that live in an area that they are not orignially from and cause harm to the environment, human economy or human health. They are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats.
The University of Illinois Extension Forestry Introduction to Invasive Species Webinar provides an introductory explanation of invasive species, including their ecological impacts and review of common invasive species in Illinois.
