Welcome! The Knox County Cooperative Invasive Species Management Area (CISMA) is a local, non-profit organization, whose mission is to minimize the impact of invasive plant species in Knox County by educating the public, monitoring and removing invasive plants, and promoting and protecting native plants.
And find us on Facebook!
Currently, we are holding our second county invasive shrub exchange program. Remove an invasive shrub, and get a free native shrub to replace it! See the program flyer here.
