The Missouri Invasive Plant Council (MoIP) advocates for making early detection and control of known and potential invasive plants a statewide priority.

What is the Missouri Invasive Plant Council?

In 2015, Grow Native! spearheaded this multi-agency, multi-industry networking and advocacy group (first called the Missouri Invasive Plant Species Task Force, then the Missouri Invasive Plant Task Force, and now the Missouri Invasive Plant Council) to bolster statewide efforts to identify and control the invasive plant species that severely impact several sectors of the Missouri economy and native biodiversity. The purpose of the council — working as a united, supportive front—is to review, discuss, and recommend educational and regulatory action related to managing known and potential non-­native invasive plants. Representatives from the fields of conservation, agriculture, botanical science, ecological services, plant production, horticulture, landscape services and design, and arboriculture make up the council.
