本文介绍的信息来自于对已发表的关于枯木退化的文章的回顾，以及对20世纪80年代卡里布高原山松甲虫爆发的林业和（或）工厂经验的人的采访。本文综述了美国西部松大小蠹（Dendroctonus ponderosae）和扭叶松（Pinus contorta Dougl.）前大声。变种宽叶黄（Latifolia Engelm.），还包括其他针叶树种的论文。现有的研究大多集中在对死亡时间不到5年的树木的利用上。总的结论是，水分含量降低，检查（与水分含量有关），和蓝变是最重要的因素涉及产品的机会和质量的损失。立松的腐烂是缓慢的（至少在研究的地区），树木更容易倒下之前，由于腐烂真菌的木材体积的显着损失。一旦树木在地面上，腐烂速度大大加快。
The information presented in this paper results from a review of published articles on deterioration of dead wood, and interviews of people with forestry and (or) mill experience from the 1980s Cariboo Plateau mountain pine beetle outbreak. The literature review focussed on mountain pine beetle (Dendroctonus ponderosae) and lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.), but also included papers on other conifer species. Most of the existing research has focussed on utilization of trees that have been dead for less than 5 years. The general conclusion was that reduced moisture content, checking (related to moisture content), and bluestain were the most important factors involved in loss of product opportunities and quality. Decay of standing pine was slow (at least in the regions studied), and trees were more likely to fall over before significant losses of wood volume due to decay fungi. Once trees were on the ground, decay rates accelerated substantially.
