Forest Health Monitoring: national status, trends, and analysis 2023

Abstract

The Forest Health Monitoring Program of the U.S. Department of Agriculture, Forest Service produces an annual national report that presents recent forest health status and trends from a national or multistate regional perspective and introduces new techniques to analyze forest health condition. In this 23rd edition of annual reports, national Insect and Disease Survey (IDS) data are used to identify recent spatial patterns of areas affected by insects and diseases. Satellite data are employed to detect geographic patterns of forest fire occurrence. Data collected by the Forest Inventory and Analysis (FIA) Program are used to explore regional differences in tree mortality. National Land Cover Database (NLCD) maps are used to detect trends in forest fragmentation across the conterminous United States. Exposure of forests to drought was summarized using data from the Parameter-elevation Regressions on Independent Slopes Model (PRISM) Climate Group and the FIA Program. Association of multidecadal repeat dryness with wildfire and bark beetle disturbance was explored for the conterminous United States using data from NLCD; IDS; Wildland Fire Management Research, Development, and Application; Wildland Fire Interagency Geospatial Services; Monitoring Trends in Burn Severity; and PRISM Climate Group.
