Thinning a 10-year-old stand of quaking aspen (Populus tremuloides Michx.) did not reduce the subsequent prevalence of hypoxylon canker (Hypoxylon pruinatum (Klotz.) Cke.). After 15 years, a greater percentage of dead aspen was found in an area thinned to 741 stems per acre than in an unthinned area of 2,636 stems per acre. Infected trees were killed more rapidly in the unthinned area than in the thinned area. The greatest proportion of cankers 5 years old and older occurred in the thinned portion of the stand.
