    As an ever-increasing number of young Douglas-fir stands in the Pacific Northwest come under intensive management, development of better tree-marking techniques based on sound scientific principles becomes essential. For this reason, two experiments have been established at the Wind River Experimental Forest near Carson, Wash., to measure the effect of different degrees of release on the growth rate of dominant, codominant, and intermediate trees. The initial test in a 41-year-old natural Douglas-fir stand has been previously reported. A second test in a nearby Douglas-fir plantation, 30 years old from seed, permits a comparison of early results.
