A recent Peter Wall interdisciplinary workshop in the Faculty on "Linking Forest Sustainability to Aesthetics " (see page 6) grappled with the various views of forested ecosystems as seen by the ecologists, forest resource scientists, landscape architects, perceptual psychologists and sociologists. In this guest editorial, Dr. van der Kamp explores some common human reactions to our stories that forests grow and change. John A. McLean, Acting Dean (604) 822-2467, fax (604) 822-8645, or e-mail mclean@interchg.ubc.ca. • EDITORIAL by Dr. Bart van der Kamp L e t me start by telling three stories. Hamish Kimmins recently took a group of European visitors on a walk through the 70+-year-old Douglas-fir stands of Pacific Spirit Park. He told them how the area was logged and burned just after the turn of the century and left to itself. Seeing the nicely stocked vigorous stands, they responded with utter disbelief, and in spite of the notched, burned stumps still visible from the logging, they turned around and left. It couldn't be true. The other day I took my pathology class to Watershed Park in Surrey to show them Phellinus root disease and conduct a root disease survey. It was the third time my teaching assistant had come along, and he was amazed. Amazed that trees which were living when he first visited the area two years ago were now on the ground, totally rotted off at the base. And for the third story, last year I took the opportunity to visit the base camp site where I spend a summer working as a cruiser for the old Inventory Division in the mid sixties. I couldn't find it at first. The familiar land- marks were gone. I knew of course what should have happened in the interval. The old landing should have filled in with hard- woods and later tolerant conifers; the vista of distant mountains overtop an adjacent young stand should be blocked, etc. but my initial reaction was one of confusion. I couldn't recognize the place! After a while, of course, things came together and it all made sense. But it was a puzzling experi- ence. Why was I surprised and confused by things I should have anticipated, and in fact did anticipate? What these stories have in common is the real difficulty we have imagining that for- ests change. Sure, we all know that clearcuts green up, that root disease kills trees, and that landings fill in, but the imagination doesn't so easily go along. We drive past a patch of forest day after day, and nothing seems to change. Or rather, the changes happen on a time scale that is outside our everyday experience. Our imagination feeds as much on the direct sensory images (our daily drive through the forest) as it does on the results of our abstract reckoning, and so it is sometimes hard to imagine what we 'know' to be true. Of course, as time goes on, and we see the same changes again and again, we go from being amazed ('eh, it's really true') to a feeling of satisfaction ('yup, things are behaving as they should'), to a sense of the commonplace. And in the end we sometimes forget our initial reaction. This dichotomy in our minds, the knowing on the one hand that certain processes are going on, and the difficulty nevertheless of accepting and imagining their outcome, is an important phenomenon. It can, for in- stance, act as a block to ecological inter- pretation - certain possibilities are not con- sidered because our imagination refuses to consider them. It took me a long time, for instance, to recognize the drastic effect of Phellinus root disease on the structure of older immature stands around Salmon Arm (and without the help of some good friends, I might never have recognized it). Similarly, this dichotomy is, I think, large- ly responsible for the impact and 'success' of pictures of barren clearcuts and wasted hillsides. I suppose good propagandists have always known that there are other avenues into human beliefs than reasoned argument, and that these other avenues are both more direct, more subtle, and less likely to be questioned. In our explicit train- ing we have been so deeply steeped in the Enlightenment tradition that we are above all rational beings - that the prime or even the only access to our beliefs is through Reason, that we have forgotten the impact and power of direct appeal to our emotions, our sense of the aesthetic, and our imagina- tion, and the way that these aspects of our being refuse to yield to reason. All this is important both to understand ourselves and to guide our public pronounce- ments. For instance, when we explain long- range forest level plans to a 'lay' audience, the arguments may be understood by the audience, but that doesn't necessarily mean that their imagination has grasped it. And until it does, they may not be ready to accept and implement the conclusion. We could probably avoid a great deal of frustra- tion if we had more realistic expectations of responses to our stories about forests; if we had a fuller understanding of the way human beliefs, (our own and others') are formed and maintained.

Forest Sciences Department RESEARCH HIGHLIGHT The nutritional significance of coarse woody debris WITH the current trend towards more natural management of forests, the role of coarse woody debris (CWD) in forest ecosystems has received increasing atten- tion. The role of CWD as a critical habitat for many species of animals, plants and fungi is well-recognized. Less is known about the role of CWD in nutrient cycling and productivity of forest ecosystems. The contribution of CWD nitrogen and phos- phorus cycles was assessed in three Rocky Mountain forests: a self-thinning lodgepole pine forest, a mature white spruce forest, and an old-growth forest of Engelmann spruce and subalpine fir. Weight loss and changes in N and P concentrations in de- composing log segments were measured over a 14-year period. Input rates were measured during ten years for CWD, one year for ground vegetation, and five years for other aboveground litter types. Organic matter accumulation in the forest floor, and N and P release from decomposing litter were simulated for a period of 40 years. The role of CWD in nutrient cycling in these forests was assessed by determining 1) the proportion of the annual above- ground inputs of C, N and P that is derived from CWD, and 2) the proportion of the C, N and P released from aboveground litter during the simulated 40-year period that is derived from CWD. During the 14 years pine logs lost 71% of their original weight, spruce lost 38% and fir lost 40%. If current trends continued, pine logs would disappear completely in about 35 years, spruce logs in 45 years, and fir logs in 35 years. Nutrient release during log decomposition differed between the two elements and among the three species of logs. The pine logs gained N, spruce logs released some N, and the fir logs released almost 30% of their original N content. This pattern was related to the initial N concen- trations in the logs, which were lowest in the pine logs and highest in the fir logs. 1000 800 600 400 200 0 1000 Pine 800 600 400 200 Spruce / •i / / 800 600 400 200 CWD Smfll woody Fir 10 20 30 Time, years Contributions of the various litter types to annual N release from accumulated organic matter at the pine, spruce andfir sites during a 40-year simulation period. DEPARTMENT NEWS D r . Scott Hinch organized and chaired a session on "Land-use impacts on fish" at the Canadian Conference for Fisheries Research, January 8-10, in Edmonton, Alberta. He also organized and chaired a session on "Sockeye salmon migrations and life history" at the American Fisheries Society North Pacific Chapter Meeting, February 15 -17 in Richmond, B.C. In January, Dr. Hamish Kimmins was appointed for the next four years as a member of the World Commission on the Ethics of Scientific Knowledge and Technology Committee. SELECT CD will be available in March. This site-specific, decision-support tool will aid in selecting ecologically viable tree species, reproduction cuttings, and regeneration methods in the coastal for- ests (CDF, CWH and MH biogeoclimatic A similar pattern was even more striking for P: the fir logs with very low initial P concentration immobilized additional P equivalent to almost four times their initial content. Earlier studies at these sites indi- cated that N was the most limiting nutrient for vegetation at the pine site, and P was most limiting at the fir site. Our findings of greatest N import into logs at the pine site and greatest P import at the fir site suggest that wood decay organisms may be compet- ing with vegetation for limiting nutrients. Foliar litter made up the greatest pro- portion (40-50%) of total annual above- ground litter input at all sites. The propor- tion of CWD in aboveground litter input was 19% at the pine site, 3% at the spruce site, and 24% at the fir site. According to the simulation, foliar litter also accounted for the greatest contribution to forest floor: 32% of the total organic matter accumula- tion at the pine and spruce sites, and 39% at the fir site. The contribution of CWD to organic matter accumulation varied from 5% at the spruce site to 30% at the fir site. Foliar litter also dominated N and P release, along with ground vegetation. The contribution of CWD to N and P release was 2% or less except at the fir site where CWD released 5% of the N. Our findings indicate that CWD is not a significant source of available N and P in these for- ests; it may actually compete with vegeta- tion for limiting nutrients. CWD has many other functions in forest ecosystems, such as base cation cycling, moisture retention, seedling establishment, and habitat. The amounts of woody debris to be maintained should be based on management objec- tives related to these values, rather than nutritional considerations.

HEMFIR is the market name of a mix consisting of two softwood species, namely, western hemlock and amabilis fir which are harvested, processed, and mar- keted together. HemFir with 101 by 101- mm cross section, commonly called "baby squares", is specially used for construction in Japan and its demand has been continu- ously growing over the past years. The variation in basic density (BD) and green moisture content (MC) between west- ern hemlock and amabilis fir has been deter- mined to be 377 and 423 kg/m3, and 69 and 85% for amabilis fir and western hemlock, respectively. Because of this high variation in green MC and BD, drying baby squares to a uniform final MC has been recognised by the industry as a significant problem that translates into difficulties in meeting the 19% maximum final MC and reducing planer splits. As has been shown in practice, prob- lems with high percentages of overdried and underdried squares are likely to appear if mixed species are dried together. Lumber with wet spots is not suitable for further processing, and overdried lumber may con- tain a considerable amount of degrade. The UBC-Department of Wood Science in collaboration with Forintek has initiated a joint research study on means to improve the quality and value of conventionally dried baby squares. Two of the strategies already tested are presteaming and presorting based on species and basic density. Experimental runs were carried out with HemFir squares in a conventional kiln. Green baby squares were exposed to circu- lating saturated steam at 100"C (presteam- ing) for 5, 10 and 20 hours, respectively. DEPARTMENT NEWS T h e Department is proud to announce that Dr. Colette Breuil has been invited to serve as the Associate Dean, Research for the Faculty of Forestry. Colette assumed this role on March 1 on her return from a six- month sabbatical research leave. Dr. Frank Lam has been promoted to Associate Professor effective July 1, 1999. Then, they were kiln dried according to a schedule developed by UBC and Forintek. The results showed a significant reduc- tion in the difference of core and shell MCs after drying as presteaming times increased and significant increase in shrinkage with an increase in presteam- ing duration. However, prolonged pre- steaming decreased the MC and shrink- age variability within the lumber and did not adversely affect the quality of the dried wood. In a second study, HemFir squares were presorted in two species and two basic density groups and then kiln dried as above. Data analysis showed that final MC distributions did not improve after The first on-line graduate-level course in the proposed "Fibre and Wood, Re- search and Education in Science and Technology" program will be offered starting April 6, 1999. This 13-week course on technology management was developed by Dr. Alan Procter, adjunct professor within the department, and the distance education staff at UBC. The separation of species. However, after BD separation, the low density squares exhib- ited shorter drying times, and lower volu- metric shrinkage, MC difference between core and shell, and variability when com- pared to the runs with high density lumber. It is apparent from these two studies that there is a substantial body of evidence point- ing towards the use of presteaming, and/or density and moisture content presorting of HemFir 101-mm squares as ways of re- ducing drying times and/or improving the quality of the dried product.

Growth and yield (cumulated growth) of stands of trees with a large diversity of species, sizes and ages are more difficult to predict than the growth and yield of uniform stands. In order to predict the growth of multi- species and multi-aged stands of trees in the southeastern interior of B.C., a growth- and-yield model called Prognosis that was developed, over two decades ago, in the United States is being calibrated for this region (Prognosis80). This model has been used in 20 forest regions of the U.S. to: 1) help plan and implement a variety of forest management objectives, 2) choose amongst alternative silvicultural treat- ments, 3) assess the impacts of disease and insects on forest health, 4) conduct timber supply analysis, and 5) project the forest inventory to the future. Prognosis grows individual trees over time using a suite of component models to predict changes to the diameter, height, and prob- ability of mortality for each tree. Highly diverse stands, under a variety of cutting patterns, including selecting individual trees, can be simulated using this model. Since forests of the southeastern in- terior of B.C. are similar to those found in northern Idaho, the northern Idaho variant of Prognosis was used as the basis for Prognosis 8 0 . Each of the component models within this variant must be tested for validity, and adjusted if the predictions do not reflect the growth indicated by measurements taken from southeastern interior of B.C. A series of related studies on the suite of component models within Prognosis80 is being conducted at UBC, including: • Examining the large-tree height and diameter growth models that were modified using southeastern interior of B.C. data. The results indicated that the adjusted models predict growth well for most ecological units included in the study (see figure). ESSF ICH IDF MS PP Ecological Unit Percent bias of large-tree height growth model by ecological units. Evaluating and calibrating the tree mor- tality model. Differences between the observed mortality, as measured on long term permanently located plots, and the predicted mortality (as reported by Prognosis80) were found. For example, in the Nelson Forest region, the model consistently overestimated (more mor- tality than that actually recorded) for western red cedar, Douglas-fir, western larch, and ponderosa pine. The mortal- ity model is now being adjusted for each ecological unit, tree species and size. • Calibrating the small-tree height and regeneration model. Due to differences in ecological classification systems used in northern Idaho and B.C., Prognosis80 does not have the capability to predict natural regeneration at the moment. However, the model can use actual data on the amount and species of planted trees if these data are avail- able. The ability to use the model to evaluate the impact of alternative silvi- culture choices on natural regeneration is important. In 1998, regeneration and small-tree height increment data were collected in the Nelson Forest Region. These data are currently being analyzed to adjust the regeneration establish- ment components of Prognosis80 and to develop growth modifiers for the small-tree component model. Once Prognosis80 is fully calibrated, it will be used to project stands and evaluate silvicultural alternatives for multi-species, multi-aged stands in southeastern interior of B.C.

Quite a few years ago (more than ten, I fear), one late-summer evening, there seemed to be some guffawing happening outside my office. I sauntered out to discover two men horsing around. "Gunn (i.e. Grant, class of '70)" I said, "what are you doing here?" (not bad since I hadn't seen him for twenty years) "and who is this other person?" "It's my son" he said (Brett, '92) "and he's going to be in your class this September". Yikes, my first 2nd-generation student. The chill wind of mortality whistled by. Currently, these progeny seem legion in the Faculty... Brace '62, Lucas, McCloy, both '70, Hodson '71 (two!), Burbee '73, Steeves, Berdusco, both '74, Purych '75, and Sutcliffe '77. Have I missed any? What about already graduated 2nd generation? 3rd, 4th generation? Let's make a list for fun. Do you encourage this following in your footsteps? Or forbid it and thus make it irresistible? More material for the Alumni News please. And it would be useful if you could tell me what your name used to be, if y ou've changed it. Please contact John Worrall at (604) 822-3516 or e-mail worrall@interchg.ubc.ca. Recent workshop Public perceptions of forestry On February 24-27, an interdisciplinary group of researchers at UBC, led by the Faculty of Forestry, hosted an international w o r k s h o p en t i t l ed "Linking Forest Sustainability to Aesthetics: Do People Prefer Sustainable Landscapes?". The event, which was sponsored by the Peter Wall Institute for Advanced Studies Exploratory Workshop Program, included participation of 30 invited eco- logists, forest resource scientists, land- scape architects, and perception experts. Part of the workshop was open to the public for scientists to share their views on the conflicts between "good forestry" and "good-looking fores t ry" , and for interest groups to comment on research priorities. Over 80 people attended this Public Day event. For further information on the work- shop including abstracts and biographies of the invited speakers, see the web site www.forestry.ubc.ca/pwall/default.htm.
