FACULTY OFFORESTRY  • NEWSLETTER •  T H E U N I V E R S I T Y OF B R I T I S H  Volume 8 No. 1  March, 1997  From the Dean's Desk Forestry in a Post-Modern World Part III J u d g i n g by the many thoughtful questions I received, my essay in the last issue cf Branch Lines apparently left readers baffled in a few places. I will attribute any confusion to the draconian word limits imposed by Uie editor, and not to any lack of clarity in writing on my part or reading on yours. The following comments are intended to respond more fully to the questions you have raised. Recall that p o s t - m o d e r n i s t s question the existence of an objective reality called "nature" and instead interpret phenomena through "social constructions" - definitions of nature that are acknowledged to depend on our culture, society and power circumstances. Nature cannot be defined entirely with reference to culture alone, however, because some scientific facts stand undisputed - a construction of nature requiring water to flow uphill unaided can simply be rejected. Science constrains acceptable constructions of nature, but generally not so tightly as to imply any one, single interpretation. While such a social constructionist view goes a long way towards explaining some of the deep currents of distress in forestry today, it leaves many questions unresolved. First, not all social constructions of nature have equally cheerful outcomes for humans. For example, in the 10th century, S c a n d i n a v i a n s settled in s o u t h w e s t e r n Greenland on grasslands emerging between  1  the receding icesheet and the ocean. 1 They brought with them Christianity and a pastoral culture dependent on sheep and cows. As the climate cooled in the 1300's, pastoral farming failed. Recent archaeological evidence suggests these farmers ate their d o g s and cows, and finally perished rather than adopting the sealhunting culture of the indigenous Thule people. Just as a social construction of nature which excluded seals as food led to the collapse of this Norse civilization, a social construction of nature which precludes logging old-growth timber would lead to the collapse of human settlements in most of non-metropolitan B.C. Second, the Canadian embrace of the multicultural mosaic combined with recent immigration patterns suggests greater dispersion in our constructions of nature rather than a convergence towards any one particular point of view. Through literally thousands of interviews, the social psychologist Kellert has identified a typology of nine different attitudes toward nature. 2 W h i l e the s t r u c t u r e of the t y p o l o g y appears to be robust to cultural differences, the frequency distributions of individuals in the various categories differs dramatically among countries. For example, Kellert finds "...[the] Japanese public [is] far more inclined than the American to e m p h a s i z e control over nature". 3 The North American concept of wilderness is wholly absent in Germany where humans play a leading role in the landscape. As our population makeup shifts in response to immigration, it would be startling if the predominance of various social constructions of nature did not also change.  This account is taken from H. Pringle, 1997. Death in Norse Greenland. Science 275:924-926. See, esp. S.R. Kellert. 1993.

Ecosystem management and plantation forestry: lessons for British Columbia. The Forestry Chronicle(forthcoming). 2  COLUMBIA  Third, as the new Chief of the US Forest Service Mike Dombeck observed about ecosystem management, "most resource issues today are less dependent on technical matters than they are on social and economic factors". 4 If forest management now has as much to do with values as with science, what then is the appropriate role of the professional forester? Forestry e d u c a t i o n d e a l s m o r e with "technical matters" than it does with social ones. In B.C., the Foresters Act and the ABCPF define the profession's mandate as focusing primarily on technical issues. And B.C.'s form of land ownership and management places an apparently impermeable barrier of regulation between professional practice and professional interpretation of landowner intent. Here the strong liberal traditions underlying western democracies may rescue us. These traditions, for example, reject a mandatory state religion and support tolerance f o r m a n y a l t e r n a t i v e p o i n t s of view. Multiculturalism - a distinguishing feature of Canada - makes such tolerance imperative. Forestry logically follows this tradition by seeking varieties of land management that are consistent with each of these social constructions of nature. Just as we have areas strictly protected from industrial activities to respond to the naturalistic and ecologistic constructions of nature (to use Kellert's typology), we should also have intensively managed areas focusing on t i m b e r p r o d u c t i o n and o t h e r tangible products to respond to the utilitarian and dominionistic constructions. Intermediate forms of management would capture still more of our constructions of nature. Interestingly, such planned variety in land m a n a g e m e n t is consistent with current p r o p o s a l s 5 f o r strong land-use zoning which have, to date, been based on economic and ecological arguments alone.

C o o p e r a t o r s in the study include Western Forest Products Limited, RADARSAT International, and the Canadian Space Agency. In the September 1994 issue of B r a n c h Lines (Volume 5, No. 2), we reported some results from airborne SAR data which helped us develop the methodology to examine R A D A R S A T data.  On N o v e m b e r 4, 1995, C a n a d a ' s R A D A R S A T satellite with its weather/ cloud/darkness penetrating C-band SAR sensor was launched. In December 1995, the RAINS project was funded by the Canadian Space Agency (CSA) in their Application Development and Research Opportunity (ADRO) competition. The RAINS award included 12 R A D A R S A T images to be acquired late in 1996 and 1997. R A D A R S A T , orbiting at about 800 km above Earth, is a directional viewing satellite and can be programmed to look at selected targets, at specific depression angles and resolutions.

On December 3, 1996, at 19:21 hours during a heavy rainstorm with winds gusling 50 to 100 km/hr over exposed areas, the first R A D A R S A T Fine 2 image was acquired. On December 11, at 20:44 hours, the first Standard 4 m o d e image was acquired. Both data sets were processed and delivered by the CSA within a week of imaging. We are now in the process of d o c u m e n t i n g a n d q u a n t i f y i n g the following observations: • riparian leave strips are detectable; • tree crowns give canopies image texture; • large defoliated tree crowns give strong radar returns; • partially defoliated tree crowns give a somewhat less bright return; • recent clearcuts are detectable and can be mapped; • new forest road construction in forest stands is detectable and can be mapped; • forest roads through new clearcuts are more difficult to map; • young plantations are separable from new clearcuts.

Burgess-Lane Lecture T h e Burgess-Lane Memorial Lectureship in Forestry was established in 1974 to honour Thomas E. Burgess and David E.

A fund was established by Mrs. Dorothy Burgess and Mrs. Evelyn Lane and British Columbia Forest Products Ltd. for the presentation and publication of special lectures in forestry by outstanding authorities in forestry or the forest industry.  Research legacies at the forests A vast array of researchers come through our gates each year, most with highly focused interests and expertise. They leave us various kinds of legacies. The most important ones are new information and valuable sites for teaching and further research. These build our repository of information and resources that can be passed on to future generations. Some of the physical items we inherit are useful, and can be re-used by others. For example, at the Malcolm Knapp Forest a deer pen that was originally constructed for a browse preference study, has been used since to test animal repellents, grow seedlings in a deer free environment, and test herbicides. Similarly, a quarter hectare small mammal enclosure that was built at the Alex Fraser Forest provides a perfect cattle exclosure to protect a variety of other types of research from grazing and trampling damage. Some items are not so useful, however, and require cleaning up or may even pose a hazard. For example, a board walk that was constructed around a small lake study site is currently rotting and unsafe. Steel nails used to secure research tree tags become grown over if not removed and pose a significant future hazard during tree harvesting and processing. Project materials such as plastic, metal, wood and chemicals that are left in the forest are not aesthetically or environmentally desirable and require cleanup after project completion. Wildlife are commonly attracted to foreign materials, such as plastic, and in many cases will chew on and ingest them. Above ground structures and pits or holes in the ground can create barriers and unsafe conditions for stock and wildlife travel. Some legacies are large, and require considerable effort to dismantle. Some years ago, Malcolm Knapp inherited over 20 tons of neither useful nor attractive rusty metal left behind after a research project. Some legacies are movable (like bottles, traps, and s c r e e n s ) , w h i l e o t h e r s are fixed or difficult to move (like plantings, deep pits, weirs, and physically modified trees). Some of the "fixed" legacies have proven to be extremely valuable.
