Invasive Species
Overview

Invasive species are organisms that are non-native to an ecosystem and whose introduction causes economic, social, or environmental harm. Nearly every terrestrial, wetland, and aquatic ecosystem in the United States has been invaded by non-native species, with economic losses estimated at $137 billion per year. Invasive species constitute one of the most serious economic, social, and environmental threats of the 21st century. CSREES is actively engaged in the battle against invasive species through leadership in the implementation of the National Invasive Species Management Plan and funding from Section 406 Pest Management Programs and others in the National Research Initiative (NRI) Program. CSREES also has established the National Animal and Plant Diagnostic Laboratory Networks, provides annual Hatch Act funding of Agricultural Experiment Station projects, and administers special grants related to invasive species.
