In this general technical report, 20th edition in a series of annual reports, national survey data are used to identify recent geographic patterns of insect and disease activity. Satellite data are employed to detect geographic patterns of forest fire occurrence. Recent drought and moisture surplus 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. Nearly 20 years of FIA coarse woody material (CWM) data are examined across spatial scales to assess change over time in CWM biomass, diameter and decay class, and species composition.

Keywords: change detection, coarse woody material, drought, fire, forest health, forest insects and disease, tree canopy, tree mortality
