The Forest Health Monitoring (FHM) Program’s annual national technical report presents results of forest health analyses from a national perspective using data from a variety of sources. Results presented in the report pertain to the Santiago Declaration’s Criterion 1— Conservation of Biological Diversity and Criterion 3—Maintenance of Forest Ecosystem Health and Vitality. We include status and trend information where possible, consistent with previous FHM national technical reports. Additional analytical techniques and results, new to the national report, are presented as examples of ways forest health data can be used. This report has eight sections. The first contains introductory material. The next four contain results from analyses of status and change for selected forest health indicators, e.g., several measures of forest fragmentation, mortality and defoliation-causing insects and diseases, crown condition, and tree mortality, similar to analyses in previous FHM national reports. The next two sections describe analytical techniques and provide information about assessments presented in the national report for the first time, and the final section is a summary.
