McLean, Acting Dean  •  EDITORIAL  by Dr. John Barker  Change is the rule is a phrase heard over and over again these days. Indeed, the pace of life seems to spiral ever upward with new capabilities, options, problems and opportunities descending on us in a daily deluge. In forestry, this change offers a unique challenge since foresters deal with situations covering decades rather than days. Continuity is a pipe dream. Public concerns and involvement in the forestry arena is increasing to a point where the technically desirable often seems to be overwhelmed by the politically acceptable. It is a matter of some concern to foresters how the profession should deal with this changing paradigm. It is apparent that a forester's education and training must change to meet the changing needs. The three C ' s needing consideration are: • compartmentalization, • coordination, and • communication. As the technical knowledge base required for forest management has increased, there has been a growing reliance on specialist knowledge to deal with aspects of fisheries, stability, biotech, GIS, recreation, biodiversity, value added, aboriginal values and on and on. A forester no longer represents the sole source of expertise on forestry matters.  Many other products are now demanded by the public owners. These other uses all have their specialized fields centered on their particular needs. The resulting compartmentalization of knowledge makes coherent management of the whole, difficult, since things desired in one sector are often contradictory to those deemed desirable by another. The need to coordinate management for the diversity of values is apparent. While tradeoffs between sectors requires technical input, substantial value judgement is needed. Decision makers, who are likely not foresters, require consolidated technical input communicated clearly and concisely. Thus, the forester is now required to communicate with a broad spectrum of stakeholders with a variable level of understanding of the forest. This new paradigm and the accompanying identity crisis in the forestry profession has been the subject of an ongoing debate for some time now. What is the role of foresters in the new paradigm? Of course, the traditional technical component in forestry remains but we now know clearly that forestry education needs to go far beyond this and develop a capacity for more creative, holistic thinking in order to effectively meet the pressing demands for coordination, consultation, integration and communication.  During the last decade, as a prelude to curriculum reform, the Faculty has been addressing the question of what constitutes a forester. A wide range of stakeholder input was sought by an academic task force. Gordon Baskerville's report (Branch Lines, December 1995) distilled this input and defined the desirable capabilities of the Compleat Forester. (Apologies here to Isaac Walton). The process has now moved on to the challenging task of devising a suitable curriculum to produce such a person via the BSF (Forest Resources Management) program. The new curriculum is now, after much debate and hard work, nearing completion. It stresses the integrative aspects of education and aims to provide enhanced opportunities for students to develop their integrative skills through integrated teaching arrangements and capstone case studies. It has been said that: Average teaching tells how. Good teaching explains why. Superior teaching demonstrates both. But great teaching inspires. The operative word being inspires. There is a really important need for inspiration and passion in keeping forestry effective in these turbulent times. The success of the restructured program in achieving these ends is only one part of the answer. Success will depend on the efforts not only of the Faculty and students but also the forestry community at large who must act as role models and mentors to inspire the new generation of foresters. Without this effort, forestry runs a real risk of becoming a minor player in determining the future of our forests.

A proper evaluation of the proposed use, materials specification, and installation procedures is important to good construction practices. Geosynthelic stabilisation of soils involves four basic functions of reinforcement, separation, filtration and drainage. The extent to which some or all of these functions are mobilised is governed by the site condition and construction application. This new guide, based on an integration of recent field studies and applied research, addresses these issues for use of geotextiles and geogrids in forest engineering applications. The guide includes an introduction to geosynthetics properties, basic functions, site delivery and a checklist for field inspection. Thereafter ten construction case reports are provided on forest engineering applications of roads (nonwoven geotextile, woven geotextile and biaxial geogrid), erosion control (cutslope stabilisation and log-culvert decks), subsurface drains (subdrains), riprap revetments (bank and channel stabilisation) and slopes and walls (fill slope stabilisation and lock-block bridge abutments). The construction case reports include a project overview of the general conditions, soils, application and construction procedure. Each case report has two photographs that illustrate the application (Figure 1). They also have a geosynthetics summary that addresses the type and material properties of the geosynthetic and, where appro-  DEPARTMENT NEWS D r .

Secondly, to promote the use of "best practices" in construction. To this purpose, examples are drawn from the ten reports. Guidance is developed with reference both to standard specification documents and relevant foundation engineering manuals. The guide is developed from original notes prepared for a continuing studies short course on geosynthetics for soil stabilisation. The ten construction case reports were written with funding from Forest Renewal BC. They were selected following a survey of industry and government, and include examples from the Cariboo, Kamloops, Nelson, Prince George and Vancouver Forest Region.

T  O quote a recent Business Week article (October 11, 1999), "If you are looking for signs of inflation in the US Economy look no further than the nearest gas pump. Since hitting a 12-year low of $11 (US) a barrel last December, oil prices have more than doubled to just above $25 (US)". While the US economy is running in high gear ("in sales of giant sport-utility vehicles, no less") there remains a hot debate about whether recent "climatic abnormalities" are due to our continued exponential release of greenhouse gases from fossil fuels. The recent dramatic increase in global C 0 2 emissions and corresponding global temperatures (Figure I) has raised concerns by various groups that, "even if climate change is due to the increasing release of greenhouse gases, there is little we can do to wean ourselves off the dependence on fossil fuels, when continued growth of the world economy is expected".  Over the same timeframe our Canadianbased forest products companies have generally shown poor profitability. This has been partially due to the competition in our traditional structural wood and pulp and paper markets, the high cost (stumpage) of the feedstock fibre, and high labour costs. Thus to cite a much abused cliche, "we need to do more with less!". In British Columbia it has been estimated that roughly 1 million tonnes of white wood and 2.25 million tonnes of bark are annually available as "waste" or "residual" material. Although it is likely that continued efforts would be made to develop higher value applications from this "waste" it is also anticipated that, for at least the foreseeable future, substantial amounts of residual material will still be available to produce "sustainable fuels and chemicals". Recently, US President Clinton spoke at a Bioenergy Climate Change Event and encouraged US industry to: "... make the raw material of tomorrow's economy from living, renewable resources, instead of fossil fuels, which pollute the atmosphere and warm the planet, the future of our children and grandchildren, the likelihood there will be more prosperity...and peace...will be far greater."

Over the last decade, predictions in the early 9 0 ' s that research into biotechnology and process engineering would dramatically reduce the cost of producing ethanol from biomass (Figure 2) have proven to be remarkably prescient. Currently a few energy companies, such as PetroCanada, are funding demonstration plants to assess the overall technical maturity and economics of an integrated biomass-to-ethanol process.

Single Tree Selection  N  Wildite Tree  Layout of silviculural systems area. In British Columbia, forest managers are gradually moving away from a traditional reliance on clearcutting. Our collective experience, however, is limited to a few other systems. At the Alex Fraser Research Forest, we have planned a silvicultural systems demonstration area around Gavin Lake. With support from Forest Renewal BC, we have mapped out a demonstration area that will provide feedback on the success or failure of different approaches to harvesting a particular stand type. This  100-hectare extension project is currently taking shape. Silvicultural systems are methods of treating forest stands to develop desired structures, and achieve regeneration. The demonstration area is a north-facing slope in the Interior Cedar Hemlock biogeoclimatic zone, and is aimed at showing a variety of ways of harvesting and regenerating stands. The systems to be used include a full spectrum from clearcutting to uniform selection management, with nine different systems and variants represented (see map inset). Our first cutting in the demonstration area will begin in January 2000. Harvesting will be under a group shelterwood system, incorporating small cleared gaps and adjacent thinnings in a 125 year-old Douglas-fir and spruce stand. The gaps will be cut in parts of the stand damaged by heavy snow last winter. The gaps will be planted, and the thinnings will regenerate naturally. The purpose of the demonstration area is to provide teaching and research opportunities for those who are interested in using silvicultural systems to solve regeneration problems or manage stands for uses other than timber harvesting alone.
