MISSION

To provide a continuing source of high quality information on the long-term effects of silvicultural treatments and treatment regimes on stand and tree growth and development and on wood and product quality.

ORGANIZATION

SMC is composed of forest industry, state, provincial, and federal agencies, suppliers, and universities who commit resources and expertise to the mission. The voting Policy Committee, composed of dues-paying members, controls policy with the goal of establishing the highest possible technical standards in carrying out its mission. Technical Advisory Committees (TAC’s) in Silviculture, Nutrition, Wood Quality, and Modeling, comprised of leading scientists, have been created to develop plans for research projects that are approved by the Policy Committee. The SMC has headquarters at the College of Forest Resources, University of Washington, which provides administration and staffing.

MOTIVATION FOR SMC MEMBERSHIP

The long-term future of forest industry in the Pacific Northwest depends in part on the productivity of the region's forests and on the choice of silviculturally sound and cost-effective management regimes. Large areas of plantations are being established and managed with intensive Silviculture. Reliable projections of the results of possible alternative combinations of silvicultural practices are essential for realistic evaluation of forestry investments and for intelligent choices among management regimes. Needed are reliable estimates of response to silvicultural treatments and management regimes, understanding of how product quality and value are influenced by these treatments and regimes, and methods for designing regimes that will produce high yields of wood with desirable properties. The cost of establishing and maintaining a long-term research on the scale necessary to build an adequate regional database and understanding are beyond the capabilities of any single organization. The mission can only be met through a cooperative effort of land owners, processors, research agencies, and universities. The SMC was formed to create the pool of funding, scientific talent, and long term continuity necessary to achieve the mission.

ACHEIVEMENTS

The SMC maintains a database on 400 installations in British Columbia, Washington, and Oregon, primarily in Douglas-fir and western hemlock. These installations contain 2714 plots with a variety of treatments. These contain almost 225,000 trees which together have received 1,077,000 measurements. In addition there are soil survey data, vegetation surveys, and stem section information. The SMC sponsored a large study on the processing of plantation Douglas-fir into lumber and veneer which established important linkages between silviculture, log quality, and value. It completed studies on modeling branch and crown structure and occlusion after pruning in young Douglas-fir. A growth & yield model effort for Douglas-fir stands has just been completed and the SMC has a series of publications and workshops to transfer the latest research results to members.

FUTURE

Five year plans are develop by the TAC’s and approved by the Policy Committee. An annual research planning process identifies high priority research needs, develops requests for proposals from the scientific research community, and selects the best of these proposals for funding.
