The Illinois Invasive Species Council (IIPSC) was established March 9, 2005. The IIPSC reports directly to the Office Director of Resource Conservation at the Department of Natural Resources (DNR). IIPSC's mission is to minimize the adverse economic and ecological effects that invasive plants pose to the State of Illinois. The IIPSC has a Chair and a sixteen member Board with voting privileges; however, the meetings are open to all interested people. The Board is made up of key stakeholders on invasive plant issues with 8 representatives from the nursery and landscaping industry and 8 representatives from the natural resources field concerned with habitat restoration efforts. The definition of Invasive Plant Species according to IIPSC is as follows, "with respect to a particular ecosystem, any species that is not native to that ecosystem, including its seeds, spores, or other biological material capable of propagating that species andwhose introduction does or is likely to cause economic or environmental harm."
