In 2003, the U.S. Dept. of Agriculture’s (USDA) Economic Research Service (ERS) initiated the Program of Research on the Economics of Invasive Species Management (PREISM) to examine the economics of managing invasive pests in increasingly global agricultural markets. PREISM is national in scope and focuses on decisionmaking related to species of agricultural or USDA program significance. Invasive species are defined broadly to include any vertebrate, invertebrate, weed, fungus, plant disease, livestock disease, or other organism that meets the following criteria: Is nonnative, alien, or exotic to the ecosystem where it exists or potentially could be introduced — including agricultural, range, and forest ecosystems; and when introduced, causes, or is likely to cause, economic or environmental harm. Invasive species can inflict losses on U.S. agriculture by reducing crop and livestock production, increasing food prices faced by consumers, or undermining export potential, and they can damage environmental or resource values. PREISM’s mission is to support economic research contributing to the broader effort within USDA to eff ciently prevent and manage invasive species for the sake of the competitiveness, safety, and security of the U.S. food and fiber system. PREISM’s goal is to build a high-quality, multidisciplinary research program to provide analytically based principles, guidelines, and criteria for invasive species policy and program decisionmaking, as well as economic information, modeling systems, and other tools that support decisionmaking. This report details PREISM’s Fiscal 2003-2008 activities. Tables.
