Total height volume tables for western hemlock, sitka spruce and young-growth Douglas-fir (based on 32-foot logs and an 8-inch top).

Abstract

In the Pacific Northwest logs are often scaled in lengths which average about 32 feet to facilitate logging. Although several excellent Western hemlock, Sitka spruce and Douglas-fir volume tables based on a 32-foot scaling length have been available for some time, they provide for a larger top diameter than is now used in actual practice. Other tables specify a satisfactory top diameter but are based on a 16-foot scaling length.
