DescriptionTo evaluate effects of different degrees of release on individual Douglas-fir trees, a study was started in 1952 in a 41-year-old, site IV stand at the Wind River Experimental Forest. A remeasurement at the end of four growing seasons showed that dominants respond more quickly and positively to the removal of competing trees than codominants or intermediates. A second remeasurement at the end of seven growing seasons substantiates this initial trend and adds to our understanding of the reaction of Douglas-fir trees to the removal of competitors.
