The annual national report of the Forest Health Monitoring (FHM) Program of the Forest Service, U.S. Department of Agriculture, presents forest health status and trends from a national or multi-State regional perspective using a variety of sources, introduces new techniques for analyzing forest health data, and summarizes results of recently completed Evaluation Monitoring projects funded through the FHM national program. In this 14th edition in a series of annual reports, survey data are used to identify geographic patterns of forest insect and disease activity. Satellite data are employed to detect geographic patterns of forest re occurrence. Recent drought conditions are compared across the conterminous United States. Data collected by the Forest Inventory and Analysis (FIA) Program are employed to detect regional differences in tree mortality. Results of a national insect and disease forest risk assessment, including maps, are presented. Using FIA and national land cover data, decline of intact forest is assessed by forest type and ownership. Ten recently completed Evaluation Monitoring projects are summarized, addressing forest health concerns at smaller scales.
