David Briggs joined the CFR faculty as Assistant Professor in 1980. He currently is a Professor in the Management and Engineering Division, and also serves as Director of the Stand Management Cooperative.
Dave began his doctoral studies at the College in 1968, completing his Ph.D. in 1980. During that time he also worked as market researcher for Washington Iron Works, a major manufacturer of logging machinery. In 1974, he was appointed special assistant to then Dean Bethel and in that capacity served on a several projects, including the effects of herbicide spraying during the Vietnam War, the Consortium for Research on Renewable Industrial Materials (CORRIM), and a biomass-for-energy study for the U.S. Congress Office of Technology Assessment. He also began teaching an undergraduate class in computer programming. Dave says, “I’m amazed how many former students have walked up to me years later to say what an important job skill that class provided.” He also began teaching the math sequence in the UW’s Center for Quantitative Science.
Since joining the faculty, Dave has taught courses in wood science and forest products, wood and fiber identification, and engineering economics. He says, “I greatly enjoy teaching, particularly interacting with bright, young students and watching them progress. I think the greatest reward as a faculty member comes from feedback that former students found something they learned in one of my classes was valuable to them in their careers.”
Dave was born and raised in New Braintree, MA, a small dairy farming town in the center of the state. He spent a year after high school in the U.S. Air Force, where he got his first introduction to mountain climbing—which, he says, “has become a life-long addiction!” He did his undergraduate degree in forest management at the University of Massachusetts where he also took as many wood science courses as he could fit in. His next stop was a master’s degree in wood science at Yale. For his Ph.D., he applied to all of the forestry schools near big mountain ranges and finally ended up choosing the UW.
Dave says, “My research interests have always been associated with looking at how forestry, wood science, and forest products interact. I focused my doctoral study on management science and operations research, where I could combine things into systems, look at how they interact, and optimize them to provide better information for decision making. In my dissertation on the bucking process, I combined tree shape and geometry features with surface descriptions of knots and other wood quality characteristics to develop the optimal sequence of logs to cut. Today this is a trivial analysis for modern PCs, but then it took the UW’s mainframe several minutes per tree! This analysis also taught me how much measurement systems affect results; change the log-scaling rule and you get a completely different bucking solution for a tree. I had done similar work on sawing logs into lumber and again saw how measurement systems affect the results. I was beginning to go through a rite of passage—understanding the wide array of complex and confusing measurement systems involved in forestry and forest products. This led me to update Forest Products Measurements and Conversion Factors in 1994, and to my continuing work on that publication project for which I hope to create a Web-based calculator version.”
Although Dave thought his dissertation would lead him in the direction of optimization problems in wood products manufacturing, the growing interest in how plantation practices affect wood quality and product value led him instead in the direction of applying these models to problems of evaluating stands of timber, to predictions from growth and yield models, and to the tradeoffs among volume growth, quality, and economic return. During his early work on these issues, the Stand Management Cooperative (SMC) was formed. Dave has participated in the cooperative since it formed in 1985 and was appointed Director in 1996. “The cooperative’s work is really exciting to me,” Dave says, “because it integrates all of my research interests and because of the strong involvement of many companies and agencies in designing the program and ensuring that the results are relevant.”
On the personal side, Dave and his wife, Anne, are kept busy with a small herd of llamas, a menagerie of other pets, and Dave’s addiction for another rock climbing or peak bagging junket.

Steve West reports on recent research studying buffers left along both sides of streams when surrounding areas are clear-cut. Steve is the lead researcher for the Western WA portion of a $1 million study, begun in 1991 and funded largely by Washington State’s Timber, Fish, and Wildlife Program and the DNR, with some private sector support, that is comparing buffer sizes and their effects on birds, bats, small mammals, and terrestrial and stream amphibians. Other CFR participants in the study are Kathryn Kelsey and Dave Manuwal. Along with colleagues from Washington State University and Eastern Washington University, UW researchers have found that, two years after harvest, a 50-foot buffer of trees left along both sides of a stream may provide sufficient habitat to sustain a surprisingly large number of species.
The research is studying “type 3 and 4” streams in the state, mid-size streams, which are the most common kind of waterway in the region. Currently, a variety of buffer widths from 25 feet to 200 feet are used on state and private lands, depending on various criteria. State lands managed under Habitat Conservation Plans require buffers of 100 feet. Buffers provide shade, lessen erosion, and maintain cool, wet habitats for species that prefer or require them. Although preliminary, these results, says Steve, “may be good news for both the timber industry and wildlife. The research is not yet complete and it is too soon to tell whether these narrower buffers will retain species permanently. It takes about 18 to 20 years for the forest canopy to close, and additional surveys will be needed now, 10 years from now, and when the forest becomes reestablished.”
Although the study does not include fish, current decisions about buffer width must also focus on the needs of salmon that need shaded streams to maintain cooler water temperatures. Steve says, “Additional research is also needed on the relationship among species survival and both streamside and upland habitats; many species need both types of habitat to survive. I’m now getting ready for the next round of observations—which means a constant search for new grant funding.”
A copy of the complete report, “Effectiveness of Riparian Management Zones in Providing Habitat for Wildlife,” is available free of charge from WA DNR.
