Recently, an invasive Asian beetle known as the Emerald Ash Borer (EAB) (Agrilus planipennis Coleoptera: Buprestidae) has emerged as a threat to Ash trees in the Midwestern United States and Canada (McCullough and Katovich 2004).  Significant infestations in Michigan and nearby areas have all but doomed nearly one billion native ash trees.  This paper presents an argument for the establishment of a widely accessible knowledgebase of information on the EAB’s spread capabilities.  We argue that spatial dynamic modeling stands as a flexible and powerful decision support system platform.  We present initial simulations of EAB spread scenarios constructed using tree information and land use data collected for DuPage County, IL, an uninfected suburban county in the Chicago metropolitan area.  These simulations test policies focused on impeding the costly spread of the beetle.  This analysis also presents a framework for further studies assessing the economic impacts on municipalities and counties due to tree removal costs and aesthetic damage.  Our work points to human driven movement as the major vector for EAB spread throughout our study area.  Here, the focus falls on the ability of state and county implemented firewood quarantines to act as effective policies for slowing EAB spread.
