Abstract
  • These are the proceedings of a short course in the manage­ment of young Douglas-fir and western hemlock conducted by the School of Forestry, Oregon State University, June 16-18, 1969. Upon recommendations of participants in the 1968 short course, this course was designed to enlarge upon the inventory, operational, and economic aspects of management as presented in the 1968 proceedings. The course included one day of lectures and discussion on the campus of Oregon State University and two all-day field trips. Participants observed commercial thinning operations in Douglas-fir and western hemlock and the use of the Hypo-hatchet in chemical, precommercial thinning of Douglas-fir. They also participated in marking Douglas-fir for a commercial thinning. The 67 registrants for the short course-all professional foresters-came from British Columbia, Washington, Oregon, and California. Two federal agencies, three state agencies, three universities, one city, and 22 private organizations were represented.
