ABSTRACT
Yellow-cedar trees have been mysteriously dying for more than a century in southeast Alaska. As these stems continue to stand for decades in the forest, foliage, twigs, and branches deteriorate. The sapwood in the stem degrades, leaving columns of essentially heartwood standing like ghosts in the forest until they eventually drop. To estimate the potential for utilization of these trees, several experiments have been initiated to characterize the natural durability of heartwood from dying and dead yellow-cedar trees. The objectives of this study were to characterize the durability of heartwood in living and dead stems ...
