Abstract

A study established in 83-year-old, even-aged stands of Sitka spruce (Picea sitchensis (Bong.) Carr.) and western hemlock (Tsuga heterophylla (Raf.) Sarg.) at Cascade Head Experimental Forest in the Siuslaw National Forest on the Oregon coast traces their development for 33 years. Statistical data collected from 12 permanent sample plots during four periods of growth illustrate the tremendous productive capacity of the Sitka sprucewestern hemlock type.
