Title: USFS_FHAAST_NIDRM_Map_Basemaps
Author:
Comments: The composite risk dataset is the central product of the 2024 National Insect and Disease Risk Map (NIDRM). Risk is defined as: the expectation that 25 percent or more of the standing live basal area of trees greater than 1 inch in diameter will die over a 15-year (2024 to 2038) time frame due to insects and diseases. The 2024 NIDRM represents the integration of 172 individual insect and disease hazard models, all constructed within a common GIS-based, multi-criteria framework that can account for regional variations in forest health. The production of the 2024 Risk Map has been a highly collaborative process led by the USDA Forest Service (Forest Service) Forest Health Assessment and Applied Sciences Team (FHAAST) and Forest Health Protection (FHP).
Subject: The primary goal of the 2024 National Insect and Disease Risk Map (NIDRM) is to provide policy makers, USDA officials, and federal and state land managers with a strategic assessment of the risk of tree mortality due to major insects and diseases. Risk, or more precisely, “hazard”, is defined as: the expectation that, without remediation, 25 percent or more of the standing live basal area of trees greater than 1 inch in diameter will die over a 15-year (2024 to 2038) time frame due to insects and diseases. The 2024 NIDRM is as a strategic, broad-scale planning tool that can be used for administrative activities and work planning
