In a bioeconomic framework to address the threat of invasive species, one of the objectives is to provide estimates of the regional economic and ecological impact an invasive species will potentially inflict upon a region. Achieving this objective requires addressing six steps: 1) estimate the potential habitat, 2) predict the spread, 3) estimate economic and ecological impacts, 4) determine the regional consequences of spread through the economy and ecosystem, 5) determine cost and effectiveness of different prevention and control strategies, and 6) link distribution and spread models to optimize resources. We are currently using this framework to assess the potential economic impact of the emerald ash borer (Agrilus planipennis; EAB) invasion on Ohio and Michigan. Here we highlight models of EAB spread, estimates of the distribution of ash trees, estimates of regional and localized economic impacts, and predictions of the optimal timing and execution of strategies to control the spread of EAB on a regional basis. The objective of this research is to provide policy-makers with quantitative guidance for cost-effective alternative strategies to control, prevent, or slow the spread of emerald ash borer.
