British Columbia is in the midst of the largest outbreak of the mountain pine beetle ever recorded in western Canada. Mature lodgepole pine trees form the bulk of the trees under attack. The mountain pine beetle) carries several specific blue-stain fungi that decrease the wood moisture content and weaken the tree defence mechanisms, eventually leading to tree death. Blue stain develops quickly in the sapwood of dying trees. Blue stain carries over into products made from the stained logs, affecting what products can be made from the wood and profitably sold. Infested trees also dry and develop splits and checks as the drying stresses are relieved. The physical condition of the wood affects how it can be processed. This paper discusses current knowledge of the properties of post-mountain pine beetle wood, and its use and marketing. It draws upon information from the literature and current research in Canada that pertains to properties of blue-stained and dead wood. Implications for use of post- mountain pine beetle wood for various products are discussed, significant data gaps are identified, and recommendations are made for research to bridge these gaps.
