Abstract

Decay in Colorado aspen, Populus tremuloides Michx., was extensively surveyed in 1954-56, but volume estimates were presented on a cubic foot basis. This paper reanalyzes the data on a board foot (Scribner) basis. Tree growth and gross and net volumes per acre expected on commercial aspen sites are given. Decay volumes are correlatzd with site class and tree age. Cull increased at about 0.5% of the gross volume per year after age 50 on site classes 1 and 2. On site class 3, cull exceeded 50% regardless of age within the ages sampled. The most damaging fungus was Phellinus tremulae.
