The Forest Health Assessment & Applied Sciences Team (FHAAST) produces publications, reports, and posters that address forest health-related disturbances. Topics include forest insects and diseases, native and invasive species, biological control, biopesticides, aerial survey, forest disturbance detection and risk assessment.
A framework from Rocky Mountain Research Station scientists can help managers decide if, when, and how to use eDNA sampling technology for invasive species monitoring or surveillance.

Northern pike are native to Alaska, Canada, and much of the central and eastern continental United States. Genetic evidence reveals the role of human transport in the spread of invasive northern pike in the Columbia River basin.
For 21 consecutive years, researchers from the USDA Forest Service and partners at North Carolina State University have tracked the status and trends of forest health across the U.S. Annual assessments of forest health are key to understanding whether year-to-year changes are part of longer-term trends. Forests constantly change because of tree mortality and growth, weather events and climate trends, and disturbances from stressors including fire, insects, and diseases.
