Abstract
Timber stands in western Washington are managed for many purposes. Such stands yield commodity and noncommodity outputs, such as recreation, wildlife, visual resources, or watershed benefits, and often from the same stands. Annosus root disease is widespread in many mixed conifer stands within the western hemlock, mountain hemlock, and Pacific silver fir zones west of the Cascades. In stands managed on commercial (commodity output) rotations, annosus root disease is not considered a major management concern. This is not true of stands managed principally for noncommodity outputs such as recreation, wildlife habitat, visual resource, or watershed benefits. Such stands are typically on rotations in excess of 140 years. For this reason, experimental stump treatment with borax was considered for the reduction of potential future inoculum. This paper describes one technique for the application of borax to treat stumps in two units of a commercial timber sale in the westside Washington Cascades.
