Abstract:

A naturally regenerated stand of ponderosa pine (Pinus ponderosa) was thinned in 1966 to determine the effects of spacing on crop-tree mortality caused by Armillaria root disease in central Oregon. After 20 years, crop-tree mortality in unthinned plots exceeded that in the thinned plots (1.6 vs. 0.8 trees/ac/yr). Crop-tree diameter growth, however, was greater in thinned plots (0.2 vs. 0.1 in./yr). Forest managers should not defer thinning of similar stands because of Armillaria root disease. West J. Appl. For. 4(2):58-59, April 1989.
