Description
The national Forest Health Monitoring (FHM) Program of the Forest Service, U.S. Department of Agriculture, has three main objectives (Riitters and Tkacz 2004): (1) to identify forest ecosystems where conditions might be deteriorating in subtle ways over large areas; (2) to verify and define the extent of deterioration in forest ecosystems where potential problems are identified; and (3) to understand the processes that cause forest health problems so strategies can be developed for problem mitigation and prevention.
