Map of Noxious Weeds in Arizona served by University of Arizona AgNIC - Rangelands. This map shows the general locations of many noxious weed infestations that occur throughout Arizona. This information was obtained through a 1993 questionnaire and field survey conducted by the Arizona Interagency Noxious Weed Coordinating Committee (AINWCC), an ad hoc organization that deals with Arizona noxious weed issues.
