    Description

    An intensive decline and mortality problem is affecting yellow-cedar trees in southeast Alaska. Yellow-cedar snags (dead trees) could be important to the economy in southeast Alaska, if some high-value uses for the snags could be established. Due to the high decay resistance of yellow-cedar, the rate of deterioration is so slow that snags may remain standing for a century or more after death. Obtaining information on wood properties from these snags is necessary to correctly assess the utilization potential of the yellow-cedar. Initial property analyses, Phase I, showed no evidence that even the oldest snags have lost strength. Black stain in the heartwood of live yellow-cedar may have an effect on strength, which will be analyzed through additional study.
