Abstract

The major types of aspen (Populus tremuloides Michaux) decay and stain that occur commonly in Alberta are desribed and illustrated. Internal stem defects are classified into five new categories on the basis of color and hardness. External indicators of decay and stain and other conspicuous stem abnormalities of aspen are described and illustrated. The use of a prototype wood hardness measuring device is outlined, and sampling and measurement guidelines are presented.
