FACULTY  OFFORESTRY  • NEWSLETTER  • THE U N I V E R S I T Y  Volume 2 No. 1  OF B R I T I S H  COLUMBIA  January 1991  From the Dean's Desk W h a t will the forester of the 1990's and beyond need to know? Our planning process responds to this question in several ways. • A task force on the undergraduate B.S.F. curriculum, chaired by Prof. Peter Pearse, is considering alternative models of undergraduate education as well as the need to expand curriculum content. Approaches under consideration include the current structure (four years in the Faculty), two years of Arts or Sciences followed by two years in the Faculty, and two years of Arts or Sciences followed by three years in Forestry leading to a Master's degree. Agreement on the need to expand the curriculum content centers around written and oral communication skills, professional ethics, and the social and political aspects of forestry. The problem is how to add to the already full curriculum without diminishing the important technical components. • A task force chaired by Prof. Douglas Golding will propose greater emphasis on nonresearch oriented Master's programs. These will provide the opportunity (i) for specialization in some applied branch of forestry, and (ii) for individuals with Bachelor's degrees in allied areas to complete the courscwork necessary for RPF registration. • A task force chaired by Prof. Don Munro is developing an approach for the Faculty to become more involved with continuing studies in Forestry. The science and practice of forestry change over time: what was taught in the 1970's probably no longer represents the state-of-the-art. Thinking of the B.S.F. as simply the first step in a life-long process of learning will not only improve the practice of forestry, but also the quality of the first degree. • A task force chaired by Prof. A1 Chambers is examining our role in international forestry. We plan to develop closer tics with a few other universities and Pacific Rim countries.  Faculty Publications Supplement T h i s mailing of Branch Lines includes a supplement listing publications produced by Forestry Faculty members in 1990. The listing is alphabetically sorted by first author and shows Faculty member names in boldface type. Many of the publications on this list are readily available in libraries, others may be harder to track down. If you have difficulty finding any particular publication, please contact the appropriate Faculty  member directly. Contact directions are provided on the back page of the publications supplcment.Q  ATTENTION U B C Forestry Alumni T h e Forestry Alumni Division Newsletter, previously distributed to forestry alumni once a year, will in future be included as an annual supplement to Branch Lines starting in May, 1991.

I would like to hear your views on these initiatives, in person, by letter, fax (604) 222-8645, phone (604) 228-2467 or E-mail (CLARK_BINKLEY@MTSG.UBC.CA).a  members, worldwide on an annual basis. Because of budgetary constraints in the past, only two of the past ten newsletters were circulated outside of B.C. The last two wider circulations have re-established contact with many of the more distant alumni and their news will be published in next May's Branch Lines. Hopefully, this will continue to lead to even greater feedback, and the alumni network will expand rather than contract. The Forestry Division executive is currently planning an informal gettogether of alumni and UBC Forestry students in early March (tentatively set for March 12, 7:30 pm following the Division's Annual Meeting) at the MacMillan Building on campus. This will be an opportunity for students to meet alumni and discuss any forestry issues. This will also be an opportunity for alumni to meet Clark Binkley, the new Dean of the Faculty, perhaps to convey to him your feelings regarding forestry education priorities, curriculum ideas, or new directions. The Division executive will be contacting local alumni with further details. Out-of-town alumni who could attend should contact Terry Lewis (B.S.F., 1968) at (604) 435-8668.Q  Harvesting and Wood Science Department RESEARCH  HIGHLIGHT  Moving Towards Smaller Clearcuts and Longer Green-up Periods  C  periods will have on annual allowable cuts LEARCUTTING has been the most and road construction and maintenance commonly used silvicultural system schedules.

One advantage of the large-opening clearcut system is that it requires a minimal amount of road development and maintenance, and relatively few moves of harvesting and silvicultural equipment.

Where possible, silvicultural systems other than clearcutting are being considered, but it appears that these systems can only be feasibly introduced on a small percentage of the forest land base.

As an example, the accompanying figure shows reductions to the annual allowable cut for a large coastal drainage as clearcutting constraints become more stringent. As the maximum opening size decreases, a higher percentage of the road network must be constructed in the early decades, and the amount of road maintenance tends to be higher throughout the planning horizon.

The daily production of primary treated sludge from Greater Vancouver's treatment plants is currently close to 60 dry tonnes per day. When the city goes to secondary treatment in two years, the daily production of sludge will double. Present methods of handling the sludge involve either onsitc storage, for which space is no longer available, or ocean dumping, which is no longer considered environmentally or socially acceptable. One solution to the disposal problem may be to apply the treated sewage sludge to forest land as a form of slow-release organic fertilizer. To this end, the Dept. of Forest Sciences in cooperation with the Greater Vancouver Regional District has recently undertaken a joint research project to study the environmental, ecological, public health and silvicultural implications of the application of treated municipal sewage sludge to forest lands. This three-year project involves an expanding research scope and scale of sludge applications in each year. The field research is being conducted within the Malcolm Knapp Research Forest, north of Maple Ridge, B.C. The goal of the first phase of the project is to investigate the impact of sludge applications on soil, surface water and ground water properties. Monitoring will concentrate on decomposition and release of nutrients from the sludge. Ecological and silvicultural effects arc also being  DEPARTMENT  NEWS  D r .

The second phase of the project involves sludge applications to a small experimental watershed. This phase will expand the research from a soils-water-physical chemistry assessment to a more intensive study of production ecology and human health aspects. Smaller ancillary projects within the second phase include a study to assess the efficiency with which a variety of organic waste mixes (sewage sludges, fish mortalities from fish farms, and cellulose  rich sludges from pulp mills) act as forest fertilizers. The team approach taken on this project is led by Drs. Hamish Kimmins and Morag McDonald and involves numerous faculty, researchers and graduate students within U.B.C. and the University of Victoria. The end products of this intensive program will be operational sludge application guidelines, a series of field demonstration sites, development of a computerized decision support tool and an improved understanding of the behavior of sewage sludge in forest ecosystems. Dr. Kimmins can be reached at (604) 2283549.Q  NSERC Cooperative Research Development Grant. Eight full-time employees, working in MacMillan Bloedel's three regions and the Fraser River, are looking at the level of ambrosia beetle infested booms. Other members of the team are measuring the impact of ambrosia beetle attacks on the economic returns in sawmills.  Dr. Gordon Weetman's SCHIRP project (Salal/Cedar/Hemlock Integrated Research Program) has received a further two years of funding from the N S E R C Research Partnership Program.

Finally, land that is currently unimproved but threatened by agricultural expansion can be used to grow trees. An economic analysis of these options indicates that the least costly method for reducing C 0 2 buildup is to plant trees on marginal farmland that was previously converted to agricultural production. The next best strategy is to plant trees on unimproved farmland that is not currently growing trees. The most costly alternative is to reforest NSR backlog lands. Upon comparing these options with other policies, it is clear that sequestering C in forests is a costly method of reducing C02. For example, scrapping all automobiles of pre-1983 model years will result in an overall benefit to society because fuel savings will exceed the value of the vehicles that are disposed of. Nonetheless, some forest planting options are preferred over vehicle emission policies (see graph). It is cheaper to plant trees on farmland than convert automobiles to natural gas, which would reduce C emissions by 25%. Further information about this project can be obtained from Dr. G.C.

Of particular interest was the Faculty's involvement, for the first time, in a team taught non-credit course presented to the general public. The course, which ran for eight Wednesday evenings in the fall, was offered through UBC's Centre for Continuing Education and was entitled "Our Forests: A Citizen's Course in Current Issues". Each session included a one-hour presentation by a Faculty member followed by brief responses from invited speakers from industry, government and the environmental sectors. The remaining time was kept for questions. Fifteen of the 150 individuals registered in the course attended an optional Saturday field trip to the Malcolm Knapp Research Forest at Maple Ridge. The feedback on the course was very favourable and each presentation appeared to stimulate the audience into a wide range of questions and dialogue. Many of the questions raised were on issues beyond the focus of this introductory course. For example, the issues of wood quality from second growth forests and the multinational ownership of B.C. forest companies came up on several occasions. Both of these issues could be addressed at future sessions. An immediate spin-off from this course is Dr. Hamish Kimmins' new course in forest ecology described below. It is hoped that this "current issues" course will be repeated in the fall of 1991, after which a poll of the audience will be used to direct the development of more specialized courcs in the following year. Watch the Continuing Education scction of this newsletter for further announcements. In the winter term of 1991 the UBC Centre for Continuing Education is offering three new non-credit courses in forestry, each taught by a member of the Forestry Faculty and open for registration to the general public: Forest Ecology: Only Diamonds are Forever is offered by Dr. Hamish Kimmins of the Forest Sciences Dept., on ten Tuesdays from January 29 to April 2 (7:30-9:00 pm). This course will deal with environmental issues in forestry and will provide a better understanding of how ecosystems respond to natural and human caused disturbance. There will be a one day field trip to the U B C Research Forest at Maple Ridge. Registration is S I 0 0 . Branch Lines  Several course registrants attended a one day field trip to the UBC Malcolm Research Forest. (Photo by Rick O'Neill). Small Mammals in Forest Ecology is offered by Dr. Tom Sullivan of the Forest Sciences Dept. on four Mondays from February 4 to 25 (7:30-9:00 pm). The course will be an introduction to the natural history of small mammals in B.C., particularly those with conservation and management concerns related to forestry. Registration is $40. GIS and Remote Sensing is offered by Mr. Jerry Maedel of the Forest Resources Management Dept., as a one-day workshop on Saturday, February 23 (10:00 am to 4:00 pm). Geographic Information Systems (GIS) are the latest new tools for computerbased research, exploration, management and education concerning the Earth and its resources. The course will be a hands-on workshop intended for individuals interested in the applications and potentials of GIS. Registration is $100. A fourth course, in general biology, will include one forestry session: The Compleat Naturalist a team-taught course, will have one session devoted to forestry. The course is offered on six Saturdays from February 16 to March 23 (10:00 am to 4:00 pm). The one-day forestry component will be taught by John Karakatsoulis, a Ph.D. student in the Forest Sciences Dept., and will focus on forest ecology. Registration is $185.

Forestry 131: Introductory Biometrics for Forestry is a revision of the course "Directed Study in Forest Biometrics" by Drs. A. Kozak and J. Demaerschalk, which was previously offered through UBC Access as Forestry 449. The new biometrics course, which was prepared by Dr. S. Watts, now matches the Faculty of Forestry's course of the same name and number. Forestry 131 will be offered three times a year, commencing in May, 1991. Forestry 238: Forest Mensuration has been prepared as a correspondence course by Drs. V. LeMay and P. Marshall. The course will be offered annually, commencing in January, 1991.

The Malcolm Knapp Research Forest was no exception. The Forest's weather details have been a matter of record since the gathering of climatic data became the Forest's 21st research project over 30 years ago. Although the rainfall records for November indicated a 20 year "high" (over 240 mm fell in one twenty-six hour period alone), the creeks and rivers issuing from the forest were well below their highest recorded levels, which occurred in November, 1989. It was probably the exceptionally low snow pack this past November that limited the effects of the precipitation and saved the forest roads and drainage structures from the considerable damage normally caused by flooding. UBC's Research Forests are used by many outside agencies as well as university researchers. The Malcolm Knapp Forest has joint venture projects with government and industry in recreation, education and demonstration. One particularly interesting demonstration project is known as the "management challenge". This demonstration involves over 50 hectares of comparative management strategies established by major forest companies, the B.C. Ministry of Forests and a group of UBC Forestry Faculty members. Each participant has prescribed and treated a small plantation area managed under their particular corporate, agency or individual management strategy. As time passes it will be interesting to see how each prescription develops. If you are out at the Forest Peter can show you some of the results to date. On a historical note, a new classroom to replace the old Recreation Hall at Loon Lake Camp has been put out to tender. At this time 39 years ago the Recreation Hall had just been completed and was ready for its first use.  Any questions concerning the Malcolm Knapp Research Forest, or any suggestions for Forest topics for this newsletter should be directed to Peter Sanders (Resident Silviculturalist), UBC Malcolm Knapp Research Forest, R.R. #2, Maple Ridge, B.C., V2X 7E7. « (604) 463-8148.  Alex Fraser Research Forest T h e University's second research forest received only brief mention in the last issue of Branch Lines. The Alex Fraser Research Forest, in Williams Lake, was created in 1987 as a result of discussion between the B.C. Ministry of Forests, the B.C. Forestry Association, the Cariboo Regional District, the Cariboo Lumber Manufacturers' Association, the city of Williams Lake and local forest companies. The Forest remains as Crown land, under tenure from the government to U.B.C. The tenure document is in the form of a Special Use Permit which gives the responsibility of management, and a licence to harvest timber, to the University. This Special Use Permit and Licence to Cut make the tenure similar, in many respects, to a Tree Farm Licence. The Forest is required to operate under an approved Management and Working Plan, a draft version of which is currently being circulated for review. A five year development plan is also in preparation. Since UBC assumed management of the 9,000 hectare forest, 44 research projects have been established, 200 students have visited the area and 4,600 cubic meters have been harvested. Any questions concerning the Alex Fraser Research Forest should be directed to Ken Day (Resident Forester), UBC Alex Fraser Research Forest, 1040 S. Lakeside Drive, Williams Lake, B.C. V2G 3A6. ** (604) 392-2207.Q  Newsletter Distribution T h e circulation list for this newsletter is made up from a combination of the Alumni Association's list of all U B C Forestry graduates, and from an in-house mailing list of individuals from the forest industry, research organizations, forestry schools and the community. It was intended that the in-house mailing list for the newsletter would include only those individuals not covered by the Alumni Association's listing. Sometimes it is not easy to make this cross-check and certain individuals may be receiving this newsletter in duplicate. Please let us know if this is happening. Also, if this newsletter has reached you by some circuitous route and you would like to receive future editions directly, please let us know. After the last mailing it was apparent that many forestry graduates had not updated their addresses with the Alumni Association. If you know of anyone who may be in this situation, please pass on the word. Requests for mailing list updates, additions or deletions should be directed to, Dr. Susan Watts, Newsletter Editor, at the address below.
