  • Insects

    Informally Refereed
    Insects are essential components of forest ecosystems, representing most of the biological diversity and affecting virtually all ecological processes (Schowalter 1994). Most species are beneficial (Coulson and Witter 1984, Haack and Byler 1993), yet others periodically become so abundant that they threaten ecological, economic, social or aesthetic values at local to regional scales (tables 6.1 through 6.3). Insects influence forest ecosystem structure and function in complex and dynamic ways, for example, by regulating certain aspects of primary production; nutrient cycling; ecological...

  • Greenhouse gas emissions and removals from forest land, woodlands, and urban trees in the United States, 1990-2018

    Informally Refereed
    As a signatory to the United Nations Framework Convention on Climate Change (UNFCCC), the United States has been reporting an economy-wide Inventory of greenhouse gas (GHG) emissions and removals since the mid-1990s (US EPA 2020). Forest land, harvested wood products (HWPs), and urban trees within the land sector collectively represent the largest net carbon (C) sink in the United States, offsetting more than 11 percent of total GHG emissions annually (US EPA 2020). Estimates of GHG emissions and removals are compiled by U.S. Department of Agriculture (USDA) Forest Service researchers and...

  • Field identification manual for Ghanaian timbers

    Informally Refereed
    Ghana is a nation rich in natural resources and tropical diversity, with forests covering approximately one-fifth of the country’s total land area. To ensure that future generations of Ghanaians can enjoy the benefits of such a rich forest resource, Ghana has been enacting and enforcing laws intended to ensure that wood and wood-derived products are legally sourced. Compliance with and enforcement of these laws depend in part on the availability of technical or forensic expertise to validate claims of legality through the correct identification of timber during its extraction, processing,...
