F A C U L T Y O F F O R E S T R Y • NEWSLETTER • T H E U N I V E R S I T Y O F B R I T I S H C O L U M B I A Volume 11 No. 3 December, 2000 From Deans' Desks Outgo ing My twenty-six month term as "acting dean" has come to an end with the appointment of a new dean for the Faculty of Forestry, effective December 1, 2000. Look to the third panel of this page for an introduction to Jack Saddler, the new man at the helm. The past two+ years have been a very busy time for the Faculty. We have moved into our new facilities in the Forest Sciences Centre and are now teaching in modern classrooms that allow us the flexibility to embrace various teaching styles. Our major lecture theatres are equipped with state- o f - t h e - a r t a u d i o v i s u a l e q u i p m e n t that enhances the teaching experience for both instructors and students. The new computer labs have greatly expanded our ability to use a wide range of instructional programs. We are setting up increasing amounts of class support material for our students on instructional web sites. With a monitored access system in place, s tudents finally have access 24 hours a day, 7 days a week, to their learning environment. Our research labora tor ies are up and running. Facul ty and g radua te s tudents are pursuing their many and varied areas of research interest. (See the summary in our Annual Report, outlines on our web site at www.forestry.ubc.ca and feature articles in each issue of Branch Lines). We have been able to take advantage of our new and very pleasant surroundings by host- ing various workshops and international conferences. During the past summer, the Forest Gene t ics Group hosted a Work- shop on Advanced Forest Gene Resource Management . In August , Drs. Innes and Bull hosted a conference on Streamlining Local- level In fo rma t ion for Susta inable Forest Management. Elsewhere on campus. Dr. Bull also co-hosted a conference in the new Liu Centre for Global Studies on "Global Vision for Forests 2050" that was supported by the World Bank/World Wild- life Fund Alliance. Faculty members have also been involved in organizing several conferences at a wide range of off-campus sites and I refer you to the Department News sections of Branch Lines for further details. In June, I had the pleasure of attending a Canadian Forestry Service/NSERC hosted meeting of the Association of University Fores t ry S c h o o l s of C a n a d a Deans in Ottawa. We spent three days in discussions with a wide range of federa l agenc ies evaluating opportunities for better linkages with national organisat ions that support forestry in Canada . As all the forestry schools in Canada now have their profes- sional forestry programs approved by the Canadian Forestry Accredi ta t ion Board, Canadian students can now complete their undergraduate education at any of the seven accredited schools. Graduates can work in the province of their choice where they are able to complete the additional require- ments to register as a professional forester. In addition to this overall mobili ty, our undergraduate students are also able to undertake exchange programs in third year. We have the faculty and the facilities to maintain UBC Forestry as a leading forestry school in Canada. There are many chal lenges ahead for forestry in Canada. I would like to lake this o p p o r t u n i t y to t h a n k the i n d i v i d u a l s , agencies and industry for their generous support in providing scholarship funds and e n d o w m e n t s in support of the forestry professionals of tomorrow. Forestry con- tinues to have one of the highest alumni participation rates in the annual telephone appeal. Your advice and counsel is much appreciated and always welcome. John A. McLean f \ I ncoming During the past few months I have been trying to visit and meet with as many people as possible before the regular d e m a n d s of the D e a n ' s j o b take care of most of my time! These brief meetings have con- firmed my already high opinion of the faculty and staff within the Faculty of Forestry and reinforced my perception that the undergradua te and gradua te student body has enough energy, enthu- siasm and innovation to make signifi- cant improvements in the way that our forests and forest products are used! Over the next six months I hope to meet with as many of our const i tuents as possible and continue my own education of the most pertinent forestry issues. I hope that in subsequent issues of Branch Lines I can share these initial impres- sions with you. Please let me know if you have any issues that you think the Faculty of Forestry should be address- ing. The multiple values of, job/wealth c rea t ion , b iodivers i ty , sus ta inabi l i ty , carbon sequestration climate change, etc. will ensure that there are no shortages of topics that should be covered in our education and research programs. I hope that I can obtain input from the many "clients" that the Faculty has to respond to, as to which issues are the most important in ensuring we obtain maxi- mum value and appreciation from our forest bounty. You can contact me through email (saddler@interchg.ubc.ca) by phone at (604) 822-2467 or visit me in the new Forest Sciences Centre. Jack Saddler V J Forest Sciences Department RESEARCH HIGHLIGHT Are riparian reserves effective? For what? Control 30 m 10 m 0 m Algal biomass measured as chlorophyll a ( + 1 S.E.) from streams with different riparian treatments, over four seasons. A THIRTY metre riparian reserve seemed like a lot of protection for a small stream when it was put into the code. How- ever, there are few published, scientif ic studies testing the effectiveness of riparian reserves of a given size for protection of stream and streamside ecosystems. We know that a supply of woody debris is probably important, but what about all the other features of streams and riparian ecosystems? Since 1996 we have been studying small s t reams and their r ipar ian areas at the Malcolm Knapp Research Forest. This is part of a large-scale study involving many members of our department. In the 13 streams and riparian areas we have been measuring invertebrates, algae, amphibians, small mammals, water quality, temperature, etc., since prior to any log- ging. Our d e s i g n uses con t ro l s , 30 m reserves, and 10 m buffers (all with three replicates), and clearcuts (n = 4). This gives us a replicated, before-after control-impact design, which is a very robust method for field studies. There are few well-designed studies of terrestrial vertebrates in riparian areas. Most of what we know about riparian protection and vertebrates is based on retrospective studies with all their attendant confounding. We used mark-recapture methods on small mammals and amphibians to evaluate the effects of harvesting or leaving riparian re- serves for these animals. In the clearcuts numbers of both groups generally decrease, but a few species actually increase - perhaps DEPARTMENT NEWS D r . Fred Bunnell has received the 2000 BC S c i e n c e and T e c h n o l o g y A w a r d "Solutions Through Research" for either his charm, sartorial splendor, or perhaps it was his work in sustainable forestry (see page 5). Dr. Gordon Weetman gave the Forest Industry Lecture at the University of Alberta in November and the Doug Little Memorial Lecture at the University of Northern British Columbia in December. In November, Dr. Chris Chanway gave an invited presentation entitled "Plant growth- from reduced competition? However, even the 30 m rese rves expe r i enced some declines in numbers relative to the control sites. These reserves might serve as local refugia to provide colonists to repopulate harvested sites, but we still need to test that. One of our instream measures is algal production. No one is surprised that re- moving riparian vegetative cover would increase light to a stream and increase algal production. However, we have found that even a 30 m reserve results in significantly increased light input and increased algae (including filamentous algae), compared to the controls (Kiffney and Richardson - unpublished data). We are still working on how light increases might affect the other parts of the stream and riparian food web. p romot ing rh izobacter ia : Viabil i ty and variability" at the 5th International Work- shop on Plant Growth-Promoting Rhizo- bacteria in Cordoba, Argentina.

The three-week review began at the end of November. Dr. Cindy Prescott has developed a new fourth year course in agroforestry which she introduced at the Coastal Agroforestry Con- ference in Cumberland, B.C. in Ocotober. We will study these stream and riparian systems for many more years. We will determine how riparian protection contrib- utes to the recovery processes for the function and biodiversity of these systems. This study will also add to a couple of rapidly-emerging issues, i.e., what do small, fishless streams contribute to downstream reaches and are they unique communities in themselves? The hard part will be figuring out what to do about them. Copies of a workshop report on this pro- ject are available while supplies last.

P r o j e c t i o n s by the C a n a d i a n Nat ional Energy Board indicate that there will be a steady rise in the amount of energy-related GHG emissions in Canada over the next two d e c a d e s , p u s h i n g I he total amount of emissions to 720 mega- tonnes (CO, equivalent) by 2025. As 27% of emissions are from trans- portation, improving the quality and efficiency of road vehicle fuels is essential for Canada to fulfil its com- mitment to the Kyoto protocol (6% reduction in GHG by 2008/2012). Bioethanol produced from agri- cultural and forestry residues or the cellulosic fraction of municipal solid waste, provides a renewable transportation fuel and a prof i table waste management strategy that adds value to materials generally considered undesirable. Such waste manage- ment strategics can also reduce GHG emis- sions, as the photosynthesis process in plants and trees seques te rs the carbon d ioxide generated throughout the life cycle of the fuel. For the past 10 years, the Forest Products Biotechnology research group at UBC has studied various aspects of wood-to-ethanol bioconversion. Our studies have included pretreatment for liberation and separation of cellulose and hemiccl lu lose fract ions, DEPARTMENT NEWS D r . David Cohen presented a paper entitled "Factors driving softwood lumber substitu- tion in Japan" at the International Forest Products Marketing Conference, sponsored by the University of Washington, Centre for International Trade in Forest Products and the Softwood Export Council on November 13 in Seattle, Washington. enzymatic hydrolysis for transforming solid cellulose into simple fermentable sugars, and the fermentation subprocess for trans- forming wood-derived sugars to ethanol. We are fortunate to be collaborating with Mr. Don O'Connor, the former Vice President, Supply and Manufacturing of Mohawk Canada Ltd., in the use of the fuel cycic model developed by M. Delucchi and modif ied by Levelton Engineering and (S&T) : Consultants Inc. This model calculates CO,-equivalent emissions of carbon dioxide, methane, and nitrous oxide from all stages of the life cycle of various fuels and vehicles. A full fuel cycle in- cludes production, harvest, transportation, and p rocess ing of the l ignocel lu los ic feedstocks as well as production, distribu- tion, and utilization of the fuel. Drs. Robert Kozak and Tom Maness from the Department of Wood Science, Dr. Gary Schajer from the Department of Mechanical Engineering at UBC and Mr. Darrcll Wong from Forintek Canada have been awarded an NSERC Strategic Grant to develop a real time quality control system for wood machining. Dr. Jack Saddler gave a presentation entitled "World energy: The role of ethanol The results of an initial study involving various land-use scenarios, indicate that the extent of GHG emission reduction by par- tial replacement of gasoline with wood- derived ethanol depends to a large extent on the origins of the feedstock. For example, wood derived f rom short rotation forestry on lands previously covered by grass or agricultural crops, or the use of sawmill wood residue shows a good potential for reducing GHG emissions. However, trans- formation of natural forests to short rotation plantations seems to offer mar- ginal benef i t . Var ia t ions in the amount of above-ground biomass and soil organic carbon under each land-use scenario are the primary contributors to these differences. Our future work will focus on assessing the impact of other wood production practices on the reduc- tion of G H G emissions associated with the use of bioethanol fuel e.g., tree planting on marginal farm- lands. Benefits of afforestation for biofuel supply include the mainte- nance of an emission-uptake equili- brium, a one-time gain in carbon uptake from initial establishment of tree plantations, and then, the annual fossil-fuel offsetting emissions. The level of GHG emission reduction depends on the price of fossil-fuels and electricity, as well as the cost of afforestation and effi- ciency of conversion systems. Given the recent jump in fuel prices, it is expected that afforestation for biofuel conversion will be highly desired and will make significant contributions to GHG emissions reduction.

Branch Lines 3 Forest Resources Management Department RESEARCH HIGHLIGHT Using hydrologic modeling to test the Interior Watershed Assessment Procedure A CLEAR understanding of how logging af fec ts the hydrologic regime of a watershed is necessary if land managers are expected to make decisions regarding optimal logging scenarios and sustainable resource management. Modeling of hydro- logic processes is a useful way of supple- menting information derived from paired watershed experiments, and for decision- s u p p o r t a n a l y s i s . T h e U n i v e r s i t y of Washington Distr ibuted Hydrology Soil Vegetation Model (DHSVM) is a leading edge research tool for B.C. condi t ions . Digital elevation maps are used to model topographic controls on governing proces- ses using physically-based equations while GIS is used to assign land cover and soil properties to each pixel (see figure below). A D H S V M application of the 26 km2 Redfish Creek catchment in the West Ami Demonstration Forest, near Nelson was used to test aspects of the 1998 Interior British Columbia Watershed Assessment Proce- dure (IWAP). Logging has taken place since DHSVM schematic. DEPARTMENT NEWS D r . Jonathan Fannin gave an invited pre- sentation "Landsl ide runout assessment: analytical vs. empirical techniques" October 20, 2000, in Whistler, at the annual confer- ence of the Associat ion of Professional Engineers and Geoscientists of B.C. Dr. Peter Marshall has recently returned from sabbatical leave visiting the Australian National University in Canberra. Dr. Gary Bull and Sandra Schinnerl organized four international conferences: October 2 - Pacific Rim Sustainable Forestry the 60 ' s and 10% of the basin is in various states of recovery. In the management of snow dominated catchments such as Redfish Creek, a crucial decision factor concerns the elevation bands at which logging should take place. The relationship between snow covered area and streamflow accumulation has long been recognized and is exploited in the IWAP based on the notion that in the interior snow covers the upper 60% of a watershed during peak streamflow. The area above the H60 elevation is thus ex- pected to contribute most to peak flows. The H60 is the elevation contour line for which 60% of the basin is above this line as determined from a hypsometric (area- elevation) curve. Peak flow index calculations in the IWAP utilize the H60 elevation and Equivalent Clear-cut Area (ECA) which is calculated from the area affected by logging and the hydrologic recovery of that area due to for- est regrowth. The above figure compares index calculations with DHSVM predict- ed changes in peak streamflows for current conditions ("c") and 6 logging scenarios (labeled 1-6). Compared to current condi- tions, the scenarios consider additional 1/3 and 2/3 harvest levels in the lower (H100- H80; scenarios 1,2), middle (H80-H60; 3,4) and upper (H60-H40; 5,6) operable forest zones. ECA performs well in differentiat- ing between the two harvesting levels. The peak flow index also discriminates between logging above and below the H60 eleva- tion line. However, the IWAP does not Initiative, at the Liu Centre, UBC; October 4 - Developing Markets for Environmental S e r v i c e s f rom Fores t s , at the Hya t t , Vancouver; October 5-6 - International Working Group on Markets for Environ- mental Services from Forests, in Parksville, B.C.; and October 12-13 - Global Vision for Forest 2050, at the Liu Centre, UBC. In October, Dr. Stephen Sheppard gave a public lecture "Aesthetics and visualization of alternative forest harvesting practices" at Selkirk College in Castlegar, B.C., under the distinguish between logging concentrated in the lower and middle forest zones, where- as D H S V M predicts smal ler peak flow changes for scenarios I and 2, as compared to 3 and 4. Furthermore, while I and 2 re- present higher harvest levels than current conditions, peak flow increases for these 2 scenarios are smaller. Additional logging at low elevation reduces maximum stream- flow compared to current conditions be- cause increased melt rates at low elevation advance the rising limb of the hydrograph and lower the annual peak. This snowmelt desynchronization effect of logging at low elevation is not accounted for in the IWAP. I W A P testing was undertaken in collabo- ration with Dave Toews and Rita Winkler, B.C.

Dur ing the b reed ing season re- duced mobi l i ty increases vulnerabi l i ty to prey, d is turbance and persecut ion. T w e l v e r a p t o r s p e c i e s , e a c h w i t h unique habitat requi rements , are known to breed at the Alex Fraser Research Forest . Nest ing sites vary f r o m cl i ffs and cavit ies to large stick structures. S o m e raptors build new nests each year and others take over abandoned nests of other species. Current ly there are ten raptor nests identif ied at the Forest . Four of these nests (three ospreys and one northern goshawk) were con f i rmed to be act ive in 1999 and 2000. T h e other six nests are thought to be- long to ospreys and red-tailed hawks . Osprey platform nest in Douglas-fir snag Knife Creek. Red-tailed hawk nest in aspen at Knife Creek. M a n a g i n g for one raptor species may preclude another. For example , northern goshawks require closed canopy condi- tions and are unable to compe te with the l a rge r and m o r e a g g r e s s i v e r ed - t a i l ed hawks in open areas. M a n a g e m e n t strate- gies for these two species mus t be qui te different. There is no blanket prescription suita- ble for manag ing all raptors. In general , raptor managemen t should address the l ikelihood of a species ' presence, the conservat ion status and range of that species , the f r equency of the crit ical habitat e lements for that species and any local constraints on forest manage - m e n t . C o n f l i c t i n g r e q u i r e m e n t s m a y necessitate prioritisation.
