Invasive Species Risk Assessment

The Invasive Species Risk Assessment Program (ISRA) provides information to support the detection, prevention, and suppression of invasive forest insects and diseases. Products provided through ISRA include pest reports, introduction, establishment, susceptibility, risk assessments, hazard maps and sampling design tools. The products were developed by the USDA Forest Service, Forest Health Assessment & Applied Sciences Team (FHAAST), in collaboration with several experts both internal and external to FHAAST including individuals from: University Academics, the USDA Forest Service Forest Health Monitoring Program (FHM), Early Detection and Rapid Response Program (EDRR), and Research; as well as the USDA Animal Plant Health Inspection Service (APHIS) Center for Plant Health, Science and Technology (CPHST), and Plant Protection and Quarantine (PPQ).

Invasive Pest Risk Maps

The development of risk maps for economically and ecologically important invasive species provides land managers with information to assess the potential for species introduction, establishment, and landscape susceptibility.
