Missouri Invasive Plant Task Force (MoIP) - to identify and control invasive plants


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 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 task force—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 task force.
