DescriptionA test of 10 provenances was established in 1969 on the central coast of Oregon. The provenances tested included Juneau, Alaska, and Sandpoint, Idaho, in addition to eight well-spaced locations in Oregon, Washington, and the southern end of Vancouver Island, British Columbia. Periodic measurements through 15 years of plantation development revealed differences among provenances in height, diameter, and height/diameter ratio. The calculated variables, bole volume and aboveground biomass, showed large differences among provenances. Two provenances from northwestern Washington consistently were the most vigorous, two (Juneau, Alaska, and Sandpoint, Idaho) were the least vigorous, and the remaining six provenances shifted somewhat in ranking over time.
