Broad-scale patterns of insect and disease damage across the United States from the national Insect and Disease Survey, 2022

Abstract

U.S. law authorizes the U.S. Department of Agriculture, Forest Service to "conduct surveys to detect and appraise insect infestations and disease conditions and manmade stresses affecting trees and establish a monitoring system throughout the forests of the United States to determine detrimental changes or improvements that occur over time, and report annually concerning such surveys and monitoring" (FHP 2023). Forest insects and diseases have widespread ecological and economic impacts on forests across the United States and may represent the most serious threats to the Nation’s forests (Logan and others 2003, Lovett and others 2016, Tobin 2015). Insects and diseases cause changes in forest structure and function, species succession, and biodiversity; these changes may be considered negative or positive depending on management objectives (Edmonds and others 2011).
