Evaluations are made of the significance of root rot and frost damage evident in five 16- to 18-year-old Douglas fir plantations. Assuming that all affected trees die, two effects of mortality are considered, one beneficial in that it eliminates trees restricting the growth of neighboring trees, and the other detrimental in that it creates stand openings large enough to support a crop tree. Most of the mortality was of the former class, and there was no evidence that the stand openings created would effect any appreciable reduction in future yield from the area examined.
