Forest health monitoring: national status, trends, and analysis 2011

Abstract

The annual national report of the Forest Health Monitoring Program of the Forest Service, U.S. Department of Agriculture, presents forest health status and trends from a national or multi-State regional perspective using a variety of sources, introduces new techniques for analyzing forest health data, and summarizes results of recently completed Evaluation Monitoring projects funded through the national Forest Health Monitoring program. Survey data are used to identify geographic patterns of insect and disease activity. Satellite data are employed to detect geographic clusters of forest fire occurrence. Data collected by the Forest Inventory and Analysis Program of the Forest Service are employed to detect regional differences in tree mortality. Fragmentation status of forest types in the Eastern United States is evaluated and the area of intact forest is estimated by forest type. The presence and abundance of introduced plant species in the Northeastern United States are examined to determine what broad-scale factors might predict their distribution. Results from 16 years of ozone damage biomonitoring are presented, demonstrating overall declines in damage over time. Three recently completed Evaluation Monitoring projects are summarized, addressing forest health concerns at smaller scales.
