Second Growth Douglas-Fir: Its Management and Conversion for Value

摘要

The forest industry in Canada will become increasingly dependent on managed second-growth timber for its wood supply. In order to consider the objectives of both silviculture and utilization, studies of alternative forest management strategies require data on the relationship between site quality, stocking density, thinning, pruning and fertilization regimes, and product types, quality and values for the softwood species of commercial interest. The Douglas-Fir Task Force had the following main objectives: To estimate the physical, mechanical and chemical properties of the intensively managed coastal Douglas-fir resource of the future; To determine the value of the resource for conversion to dimension lumber and pulp and ;To develop a computer model capable of evaluating the effects of silvicultural treatments in terms of end-product value.
