Forest health monitoring: 2005 national technical reportThis article contains other documents. View all titles contained within this article here.
The Forest Health Monitoring program's annual national technical report presents results of forest health analyses from a national perspective using data from a variety of sources. The report is organized according to the Criteria and Indicators for the Conservation and Sustainable Management of Temperate and Boreal Forests of the Santiago Declaration. The results of several analyses of forest fragmentation are synthesized to evaluate fragmentation in U.S. forests. Drought in 2004 is presented, and drought over the decade 1995-2004 is compared with the historical average. Areas of intense forest fire activity during the 2004 fire season are identified. Ozone bioindicator data are used to create an interpolated ozone map of the United States, and the possible impact on sensitive tree species is examined. Aerial survey data are used to identify hotspots of insect and disease activity based on the relative exposure to defoliation- and mortality-causing agents. Data from the Forest Inventory and Analysis down woody materials indicator are analyzed to produce preliminary per-acre estimates of amounts of woody debris and carbon pools stored in down woody materials. Data from the Forest Inventory and Analysis soil quality indicator are analyzed to provide preliminary information about erosion and soil compaction, soil pH, and effective cation exchange capacity, and to produce preliminary per-hectare estimates of soil carbon.
