1. 1987. Impact of intensive forestry practices on net stand values in British Columbia. B.C.<br />
Ministry of <strong>Forest</strong>s FRDA-Report 014. 109 p.<br />
Keywords: release treatments<br />
fertilization<br />
thinning<br />
yield<br />
economics<br />
Abstract: Yield responses to major silvicultural treatments (regeneration method, brushing and<br />
weeding, spacing and thinning and fertilizer use) are analysed in relation to growth and yield<br />
theory, and their translation into operational use of treatments to increase merchantable vol. is<br />
considered. Data from coastal Douglas fir (Pseudotsuga menziesii), western hemlock (Tsuga<br />
heterophylla) and western hemlock/Abies amabilis stands and interior white spruce (Picea<br />
glauca), lodgepole pine (Pinus contorta) and wet belt Douglas fir stands are used to quantify the<br />
net present value of treatments in terms of improvement in net stand values and merchantable vol.<br />
Potentially viable treatment options are identified for each stand type present.<br />
2. 1994. Annual Report - <strong>Forest</strong> <strong>Research</strong> Laboratory, Oregon State University. <strong>Forest</strong> <strong>Research</strong><br />
Laboratory, Oregon State University. ii + 29 p.<br />
Keywords: genetic tree improvement<br />
tree/stand protection<br />
tree phenology<br />
tree physiology<br />
Abstract: Highlights of research conducted during 1993-1994 are presented, including:<br />
preliminary results of a 2-year (1992-94) field cold hardiness study of Douglas fir [Pseudotsuga<br />
menziesii] in Oregon, USA involving open pollinated progeny of 40 parents at a high and a low<br />
elevation; results of a progeny test on the frequency of second flushing of Douglas fir near<br />
Orleans, France; and variation in stable carbon isotope ratios (a measure of water use efficiency)<br />
among varieties and populations (coastal and Rocky Mountain) of Douglas fir.<br />
3. 1997. PNWTIRC Annual Report 1996-97, Pacific Northwest Tree Improvement <strong>Research</strong><br />
Cooperative. Oregon State University, Oregon, USA. ii + 29 p.<br />
Keywords: genetic tree improvement<br />
tree/stand protection<br />
tree phenology<br />
growth<br />
wood quality<br />
tree physiology<br />
Abstract: The report describes highlights for 1996-97, current research (3 projects), student<br />
project updates (3 projects), planned Douglas fir [Pseudotsuga menziesii] seed orchards for the<br />
new millennium and other planned activities of the PNWTIRC, a research cooperative operating<br />
in the Pacific Northwest area of North America (USA and Canada). Details are included of<br />
publications and finances. Details of the 3 current research projects and the 3 student projects,<br />
which all concern Douglas fir, are presented as short papers including brief results: (1) Influence<br />
of second flushing on cold hardiness; (2) Seedling drought physiology study; and (3) Quantitative<br />
