DescriptionDecayed wood plays many critical roles in forest ecosystems. Standing dead trees, called snags, provide habitat for a suite of wildlife, including several species of birds, insects, bats, and other mammals. Down wood provides wildlife habitat and performs ecosystem services such as releasing humus, nitrogen, and phosphorus into the forest soil, storing pockets of moisture, and stabilizing soil on slopes. Root wads, tree stumps, hollow trees, and partially dead trees also perform important ecological roles as wildlife habitats and sources of soil organic matter.
DecAID Advisor is an on-line decision-aiding system to help managers plan for wood decay elements for biodiversity in forests of Washington and Oregon. DecAID Advisor is a statistical “meta-analysis” and synthesis of a vast amount of wildlife and inventory data. It does not make decisions for managers, but instead, DecAID Advisor advises on size and amount of snags, down wood, and other wood decay elements to meet management objectives and to help set those objectives by forest type and structural condition class. It is the first decision-aiding tool of its kind, given its scope of species, inventory data, and topics provided.
