The Oklahoma Invasive Plant Council has developed a list of invasive plants by region.  These plants have invasive qualities and are present in the region or neighboring regions.  These are species that are not abundant yet in the area, but should be monitiored, reported and controlled before they become a bigger problem in the state. Below is a map of Oklahoma with each region labeled.
