In response to the diverse and growing public concerns about potential human impacts on our environment, the U.S. Environmental Protection Agency have initiated a cooperative national program of Forest Health Monitoring (FHM). The purposes of this report are: to describe the current approach and activities; to summarize the data that were collected in 1991, and; to outline some new directions that are being explored for possible implementation later. There are now 925 plots in the FHM national network, of which 628 plots are forested. This is about 16% (excluding Alaska) of the projected total number of forested plots that will be installed nationwide over the next several years. The installed plots are located systematically, using a probability sampling design, throughout the forests of 12 states in the eastern United States. Over 45,000 trees and seedlings of more than 100 species in 10 major forest types were measured by state and federal personnel.
