    Description

    This paper summarizes published reports of deterioration and product recovery studies conducted on dead timber. Decay rates experienced in blowndown timber are presented for western redcedar (Thuja plicata Donn ex D. Don), Douglasfir (Pseudotsuga menziesii (Mirb.) Franco), western hemlock (Tsuga heterophylla (Raf.) Sarg.), and Pacific silver fir (Abies amabilis (Dougl.) ex Forbes). Results from product recovery studies conducted on insect-killed western white pine(Pinus monticola Dougl. ex D. Don), grand fir (Abiesgrandis (Dougl. ex D. Don) Lindl.), Engelmann spruce(Picea engelmannii Parry ex Engelm.), and insect-damaged Douglas-fir are also presented.
