" Scott, our recent recipient of the Killam Faculty Research Fellowship for his studies on fish migration, reviews the results of a recent federal fisheries audit. He argues it is time to conduct the necessary research to improve current provincial guidelines. John A. McLean, Acting Dean • E D I T O R I A L by Dr. Scott Hinch "Bad forestry blamed for loss of salmon habitat" was the title of the half page article that appeared in the Vancouver Sun this past July 17. It was accompanied by a photo of a newly constructed logging road near Cathe- dral Grove on Vancouver Island. Comment- ing on an audit conducted by Fisheries and Oceans Canada1 (FOC) the article concluded that "forest road construction continues to devas t a t e f i s h - b e a r i n g s t r e a m s desp i te legislation and policies which are supposed to protect them". The audit was conducted because FOC was instructed by the Auditor General to devote more effort to compliance monitoring. Technical staff from FOC iden- tified stream crossings (i.e. bridges and cul- verts) as priority for evaluation. The audit examined habitat at 46 crossings on small to mid-sized fish-bearing streams within watersheds of a "representative" 'interior' region (Prince George Forest District) and 'coastal' region (Port McNeill Forest Dis- trict). All were constructed since implemen- tation of the Forest Practices Code (FPC). Habitat as defined by the Fisheries Act in- cludes spawning , nursery, rearing, food supply and migration areas on which fish depend directly or indirectly in order to carry out their life processes. Obviously the channel at a stream crossing is fish habitat, but so are ad jacent riparian (s treamside vegetation) areas because they contribute food and modify channels. The audit found only three crossing types: n o n - e m b e d d e d c o r r u g a t e d meta l p ipes 'Harper, D.J. and J.T. Quigley. 2000. No net loss of fish habitat: an audit of forest road crossings offish-bearing streams in British Columbia, 1996- 1999. Can. Tech. Rep. Fish. Aquat. Sci. #2319. Contact authors at quigleyj @dfo-mpo.gc.ca. (CMPs), log culverts (LCs) and bridges. In terms of in-stream habitat, overwhelmingly, CMPs caused the highest losses. Forty-three n r of bank and benthic habitat was lost per C M P crossing, compared to 11 n r lost per bridge, 2 n r lost per LC, and 1 n r lost per deactivated crossing. Furthermore. 25% of CMPs were impassable by fish due to either water velocity barriers or because they had become inaccessible at their downstream end. Thousands of square metres of up- stream habitat was made unavailable by those cross ings . An interest ing f ind ing glossed over by the newspaper article was that, with one exception. LCs were only found in the coastal region and CMPs only in the nor thern interior . Th is sugges t s 'coastal' operations may be much better than their 'nor thern interior ' counterpar t s at conserving in-stream fish habitat at cross- ings, despite the article's photo displaying coastal logging. This regional dichotomy is however blurred by a post-FPC study, cited in the audit, conducted in the Prince Rupert and Skeena region demonstrating that CMPs were installed poorly resulting in fish pas- sage barriers and impacts on bank stability. Irrespective of region, the audit found that about 400-7(X) n r of riparian habitat was lost at each stream crossing simply due to the presence of the road. Maybe this doesn' t seem like a lot but multiply it by the hundreds of crossings that are installed each year on fish-bearing streams and the audit suggests that we could be losing over 300,000 n r of fish habitat each year, of which about 30% is stream channel habitat alone. The audit makes several good recommen- dations. Most important is that CMPs should no longer be used on fish-bearing streams. The FPC Stream Crossing Guidebook for Fish Streams (SCG), a 1997 working draft, details how to protect fish and habitat. It clearly states that CMPs "rarely meet fish passage requirements" and "are considered too risky for general use", despite this, it still suggests them as an avai lable cross ing s tructure. It seems imperat ive that this working draft be updated with the audit 's recommendations and 'finalized'. Does this audit have some flaws? Yes. First, in-stream habitat quality and productive capacity were not evaluated making it diffi- cult to judge the full impact of the reported habitat losses. In fairness, this would be impossible to do on such a large scale requir- ing seasonal habitat assessments and consi- derations of all life stages and species in- cluding fishes that are "unimportant" econo- mically for which we have little knowledge. Second, even with the most fish-friendly of crossings, riparian habitat is lost. But what arc the consequences for fish? Streamside logging can destabilize banks, add sediment, and reduce recruitment of large wood into channels, negative aspects for habitat. It can also increase in-stream primary production creating more fish food, and in northern regions can warm streams to optimal levels for fish growth. The balance between nega- tive and positive habitat changes depends on climate, topography, fish species, life stage etc. But, is this a good model for evaluating effects of riparian loss from stream cross- ings. I would argue no. There has been little scientific evaluation of cumulative riparian loss resulting from bridges or culverts in forested areas on fish production or biodi- versity. It 's quite possible that the net effect on habitat and fish is negative as the audit implies but it is time that research is conduct- ed to address the magnitude of this issue. The 1992/1994 Tripp forestry-fish guide- line audits raised large amounts of public, government and industry concern hastening the deve lopment of our current riparian guidelines. Will the road crossing audit have similar stimulatory effects on the SCG and on stream stewardship? Only time will tell. Dr. Hindi can be reached at shinch@ interchg.ubc.ca. Forest Sciences Department RESEARCH HIGHLIGHT Unhealthy aspen trees support wildlife THE increased edge, fragmentation and loss of mature forest structure resulting from forest cutting, is considered to nega- tively impact forest wildlife, in particular hole nesting animals. The mixed deciduous and coniferous fores ts of the Cariboo- Chilcotin support one of the richest assem- blages of cavity-nesting birds and mammals in North America, including 8 woodpecker species, 4 weak excavator species (nut- hatches, chickadees) and 32 secondary cavity nesters (ducks, songbirds, raptors, squirrels, and bats). These cavity nesting communities are structured in Nest Webs centered around nest site availability (Fig. I). Trembling aspen, comprising only 15% of trees on our sites, is the key nesting tree as 96% of 1097 nests were in aspen. Secondary cavity S e c o n d a r y Cav i t y N e s t e r s Bushy.

For example, Bufflehead primarily use flicker holes, but also use pileated woodpecker cavities and occasionally natural holes. nesters depend on excavators or natural events to provide the tree holes they require for nesting. Northern flickers are the key excavators as they provide nests for most sec- ondary cavity nesters (Fig. 1). Pileated woodpeckers , are less abundant than flickers, but create holes used by larger ducks and owls. Although weak cavity ex- cavators avoided edges and were less abundant in frag- ments, woodpeckers and sec- ondary cavity nesters were more numerous on sites with more forest-grassland or riparian edges. Over 50% of nests were located less than 15 m from forest edges. Selection cutting treat- ments are planned (in co- operation with Lignum Ltd.) that will attempt to emulate the positive edge effects found on natural- ly fragmented sites. Cavity nesters use the full range of living and dead trees for nesting, but their s trongest prefer- ence is for live unhealthy or dead trees; 45% of nest trees were decay class 2 (15% of trees available), and another 45% of nest trees were decay class 3 4 4 4 1? • A v a i l a b l e ( n = 1 0 4 2 8 ) • U s e d ( n = 8 1 0 ) Bufflehead goideneye to 6 (10% of trees; Fig. 2). Fig. 2: Decay classes of trees used for hole nesting versus trees available. Decay class: 1 - live healthy tree, 2 - live unhealthy, etc. to 7 - a short soft snag. This research shows that mature forest structure and composition are critical for cavity nesters. Edges, particularly in the early stages of fragmentation, may provide enhanced foraging and nesting oppor- tunities for cavity nesters. Aspen should be re ta ined wheneve r poss ib le given its importance at the base of the Nest Web, particularly near edges. The value of man- aged forests and reserves to wildlife will increase greatly if they contain mature healthy, diseased and dead deciduous and coniferous trees. Mature forest reserves large enough to provide interior conditions should be retained for the weak excavators and some woodpeckers. Thus, a range of forest treatments should be part of a land- scape strategy to provide suitable habitat conditions for forest wildlife.

A case study of the B.C. value-added sector WOOD is a beautiful and functional material that is ideally suited to a countless array of industrial and consumer goods. However, the characteristics that give wood its transcendent qualities paradoxical- ly also cause quality problems. Wood, unlike other products such as steel or plastic, is an organic and heterogeneous material that is prone to variation and defects. As a result, wood processing requires very specific skills in order to achieve a high degree of quality that consistently meets the needs of various customer segments. Before discussing issues pertain- ing to quality within the context of the va lue-added wood produc t s sector, i( is important to first under- stand the definition of quality itself. This is more difficult than it seems - quality is a multifaceted and subjec- tive term that is not defined in most literature, so much as explained. Definitions typically focus either on the product being manufactured or the process of manufacturing. In fact, it can be argued that both interpreta- tions are intrinsically tied - product quality problems are merely symp- tomatic of bigger and largely controllable process quality problems. In other words, while quality may be seen in a product, it is the result of proper manufacturing and design. The American National Standards Institute has attempted to increase the understanding of quality by offering a standardized defini- tion as "the totality of features and charac- teristics of a product or service that bears on its ability to satisfy given needs". While this is not a particularly operational definition, it does point to the fact that quality is not just any one characteristic, nor the sum of many, but rather is a holistic concept akin to the value that customers place on a number of product attributes. One paradigm for defining quality that has been validated for the wood industry attempts to encapsulate the multiple attri- butes of product quality into eight dimen- sions (see figure). In order to better under- stand how this definition of quality applies product performance - product conformance - product reliability - perceived quality - product aesthetics praiuct features product durability product serviceability H 4 6 Importance rating Perceptions of Garvin's eight dimensions of quality B.C. value-added producers vs. Japanese customers. to the value-added sector, two concurrent surveys were conducted: one on B.C. value- added wood producers and the second on an important customer group, Japanese homebuyers. In each case, respondents were asked to define quality by rating the importance of eight quality dimensions. Given that wood products generally come with few 'bells and whistles', the results are not particularly surprising. In defining quality, both producers and cus- tomers place a great deal of importance on how well products are made and how well they function, while less importance is at- tached to how products look and feel. What is more surprising are the perceptional gaps that occur between producers and cus tomers on three quali ty at tr ibutes: perceived quality, product durability and product serviceability. Value-added wood producers in B.C. seem to place a great deal more importance on perceived quality (the image of their companies and products) than this particular customer group. This speaks to the fact that customers may not be loyal to any one company and, in fact, may be readily willing to substitute wood products. Two of the reasons that they may do so are the fact that this customer group rates product durability and serviceability very highly in defining quality, while producers do not seem particularly interested in the attri- butes that define quality once the product has left the manufacturing facility. This makes sense, given that it is the consumer who is in posses- sion of a product for the duration of its service life, but it also seems to be a myopic strategy, especially if companies wish to encourage repeat business. In the final analysis, it goes with- out saying that B.C. 's value-added manufacturers need to produce high quality wood products in order to remain globally competitive. This must begin, first and fore- most, with a complete understanding of what quality means from their customers' point of view.

Lam and Prion successfully organized the World Confer- ence on Timber Engineering 2000 in Whistler, B.C, along with post-conference tours at UBC and Forintek. The conference attracted over 400 delegates from 36 countries. Five high profile keynote addresses and 270 tech- nical papers were presented, 90 of which were in the form of posters. Dr. Dave Cohen presented a paper at this meeting entitled "Case study of an environmental residen- tial building system for Hokkaido". Dr. Cohen has also published "Wood market trends in Japan" with Chris Gaston and David Fell (FRBC/Forintek Canada Corp./Natural Resources Canada) and "Survey of consumers regarding nine per- formance criteria for new home rating and labeling development in Japan" (COFI, Japan /FRBC/SPF Working Group). Dr. John Ruddick has been elected third vice president of American Wood Preser- vers Association. The first Canadian to be elected to this position. In July, Dr. Jack Saddler presented a plenary paper entitled "Wood-to-ethanol: Options and targets for commercialization" at the ISAF XIII International Symposium on Alcohol Fuels, in Stockholm, Sweden.O Branch Lines 3 Forest Resources Management Department RESEARCH HIGHLIGHT Spectral unmixing of mountain pine beetle attack FORESTERS need timely information of the exact locations of mountain pine beetle (MPB) attack in order to finalize forest operat ion planning. Ground probes and aerial sketch-mapping are the tools current- ly used. Ground probes need people on the ground which limits the area that can be covered. Aerial sketch-mapping relies on finding trees whose foliage has turned red- brown (red attacks), which occurs after the beetles have flown and infested new trees. The goal of this project was to use Landsat Thematic Mapper data to locate stands of lodgepole pine which had been infested by M P B during the current growing season (green-attack) and past growing season (red- attack) using a technique known as linear spectral unmixing. Linear spectral unmixing uses pixels containing pure samples of scene constitu- ents (endmembers) to predict the fractional composition of each pixel. The digital forest cover data were used to stratify the suscep- tible lodgepole pine stands into three age groups and eliminate non-susceptible stands. With the forest cover map overlaid on the August 23, 1998 landsat image, pixel DN values for 14 endmembers were then col- lected using a ground-probe map of known attack: red-attacked (3: one for each age group), green-attacked (3), lodgepole pine presumed healthy (3), spruce (3), soil and shade. After the unmixing had been per- formed, the classified pixels within each stand were averaged and appended to the forest cover GIS data. The final composite map showed the predicted fraction of MPB attacked lodgepole pine within each stand. Since 19 map sheets covering 3463 km2 were assessed, an aerial survey was con- ducted over some portions of 14 of the map sheets to assess the validity of the results. Assisted with the NASA-developed plant stress detection glasses, one person made calls of attacked trees in stands, while the forest manager marked the calls on the attack-fraction map. The results of the aerial survey are given in the table below. 44.25% of the calls were in stands with an attack probability of greater than 77%, and 86.7% of the calls of red-attack were in stands with a greater than 50% probabil i ty of attack. All of the attack calls were in stands with a greater than 32% probabil i ty of attack. Conversely 56 .7% of the stands "traversed" had no calls and had a <32% probability of attack, whereas 87.5% of the stands with no calls had < 5 0 % probability of attack. Spectral unmix ing was conducted by M.Sc . cand ida te Zachary Bor to lo t and funding was provided by Plateau Forest Products Ltd., Vanderhoof.

Her Royal Highness is the president of the Chulabhorn Research Institute in Bangkok, an institute that she formed in 1987 to promote scientific research in Thailand. Her visit to the Faculty of Forestry focussed on our Genetic Data Centre where Dr. Carol Ritland, director of the Centre, explained the mandate and activities of this new group (see article below). Her Royal Highness was accompanied by Sunai Bunyasiriphant, Ambassador to Thailand, for her visit to UBC. We look forward to the possibility of future cooperative research projects with the Chulabhorn Research Institute in Thailand. Genetic Data Centre Open House The Genetic Data Centre was established in 1998 in the new Forest Sciences Centre at UBC. With recent support from the Canadian Foundation for Innovation, the Centre has now been furnished with state-of-the-art equipment and research projects are well underway. The facility is particularly useful to people who have not invested in equipment for molecular marker work, but who have research problems that would benefit from the insight, direction and results possible from the use of molecular gene- tics. The laboratory has become a common meeting ground for molecular applications in population, quantitative and conservation genetics. We are planning our first public Open House for the Centre in January 2001. Look for further details in the next issue of Branch Lines, or check the Faculty web site.

UPCOMING CONFERENCES The Nature and Culture of Forests: Implications of Diversity for Sustainability, Trade and Certification (May 10-13, 2001) The Institute for European Studies, in cooperation with the Faculty of Forestry, is organizing a conference to take place in the Forest Sciences Centre at UBC. The goal of the conference is to address how diversity in cultural values shapes the operative concepts of "respect for nature" and impacts forest policy decision-making. The Nature and Culture of Forests will be organized along three thematic lines: diversity in the nature of forests (biodiversity and dimensions of sustainability), plurality in culture (percep- tions, values and perspectives), variability in approaches to certification and man- agement (implications for policy and trade). The conference is timed to coincide with Sweden's presidency of the European Union.

John Innes and Gary Bull, was held in the Forest Sciences Centre on August 28- 29, 2000. The workshop examined some of the links between planning, forest certifi- cation, and criteria and indicators of sus- tainable forest management. Over 100 dele- gates heard speakers from five countries explain some of the opportunities associ- ated with the various different schemes that have evolved to examine the sustaina- bility of forest management practices. Some of the overlaps and linkages be- tween the different systems were identi- fied and steps will now be taken to increase the efficiency with which these are applied in B.C. and elsewhere. The proceedings will be published in book form in 2001.
