    Description

    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. Drought in 2005

    is presented, and drought over the decade 1996–005 is compared with the

    historical average. The relationship between lightning frequency and forest

    fire occurrence is investigated. National air pollution data are used to estimate

    the exposure of forests to ozone, wet sulfate deposition, and wet deposition of

    inorganic nitrogen. Baseline results of lichens, as an indicator of air pollution

    in the Pacific Northwest, are presented. Aerial survey data are used to identify

    hotspots of insect and disease activity based on the relative exposure to

    defoliation- and mortality-causing agents. Marine cargo data are analyzed to

    identify locations where exotic insect pests are likely to be introduced. Forest

    Inventory and Analysis crown condition data are analyzed to identify spatial

    clusters of plots where trees have relatively poor crowns, which might indicate

    forest health problems.
