TIMBER GROWTH AND VALUE CONFERENCE

PROCEEDINGS

 

INTRODUCTION

 

The Timber Growth and Value Program is one of three programs funded by British Columbia’s Forest Investment Account, Forest Science Program (FIA-FSP) to promote sustainable forest management policies and practices in British Columbia. The Timber Growth and Value Program represents a 10-year strategy (2006-2016) that seeks to improve timber growth and value in British Columbia. The program focuses on research addressing key knowledge gaps identified as priorities by the FIA-FSP Forest Science Board. To address this, the Bulkley Valley Research Centre organized and hosted the Timber Growth and Value Conference in February 2008. The research topics presented at the Timber Growth and Value Conference were structured around eight themes identified by the FIA-FSP Timber Growth and Value Program. Although not all projects presented at the conference were associated with FIA-FSP, it was apparent that a number of different agencies and researchers have common interests in continuing to improve sustainable forest management and delivering new information to practitioners, managers, and policy makers. Ultimately, continued interest in these areas and opportunities to share research will generate new management solutions more effectively. The objectives of the conference were to introduce the research and management communities to the state of knowledge regarding timber growth and value, identify operational applications of this knowledge, and provide an opportunity for researchers, practitioners and managers to meet and synthesize current research.

 

A number of important strategic goals of the FIA-FSP were outlined at the conference. These included strong continued support for research promoting sustainability and improving timber growth and value, guidance in the development of a provincial forest extension program, the development of efficient and effective processes for determining annual priorities, and the encouragement of stable funding. A major emerging challenge of maintaining multi-year project commitments with insufficient funds was addressed at length, suggesting less allocation of funding for current calls for new proposals. The development of the First Nations Forestry Council was identified as a significant step forward in addressing First Nations research priorities and involvement. Active collaboration in the form of partnerships with FIA-FSP was also highlighted as a key to effective incorporation of priorities and funds.

 

The eight themes outlined by FIA-FSP Timber Growth and Value Program were the focus of the projects presented at the conference.

 

  • The basic research on tree growth and stand development theme included projects highlighting the importance of understanding basic biological processes in complex stands to improve operational models and decision-support tools.
  • The design and analysis of silvicultural systems theme included a comparison between different silviculture systems and management regimes to measure regeneration potential and maximize timber volume and value in a stand.
  • The growth and yield modeling/predictions theme introduced several approaches to applying and improving models and decision-support tools that predict tree and stand characteristics and relate to the production of timber volume and value.
  • The timber losses to environmental and biotic factors theme described approaches used to measure forest changes. Highlighted were stands recently attacked by the mountain pine beetle (MPB) and their regeneration patterns.
  • The analytical techniques and models for strategic analysis theme introduced a technique developed for integrating various data sources and models for resource analysis or local land-use planning.
  • The marketable resources other than timber theme described the effects of silviculture systems and management practices on non-timber forest products, and the values derived from non-timber forest products.
  • The climate change theme presented new approaches to predict and assess the effects of climate change on stand growth and forest health at multiple scales, ranging from individual tree, to forest and landscape. The forest growth and health concerns included Dothistroma needle blight, MPB, and fire.
  • The forest harvesting and engineering studies on salvaged MPB-killed timber theme included projects related to the design of cost-effective and environmentally appropriate methods of harvesting and hauling of MPB-killed timber.

CONCLUSIONS

The focus of the Timber Growth and Value Conference was to synthesize current research designed to identify key short- and long-term forest management challenges. The conference also highlighted the value of sharing research and, as a result, the direction for new research. There are several key research needs that have become evident through this conference. Firstly, the need for more spatially explicit information was identified as a requirement for future landscape level research and forest management strategies. Secondly, their is a clear need to improve models designed for use of planners and silviculturists in predicting changes in tree and stand characteristics. Finally, the value of other high-resolution tools (i.e., dendrochronology) in reconstructing historical events, such as climate and fire, and their impacts on forest health was discussed.

 

The FIA-FSP demonstrated a clear commitment to the development of a research program that promotes continued support of science-based knowledge in sustainable forest management in British Columbia. The focus of FIA-FSP on improving its’ effectiveness as a funding agency was clear and further demonstrated by its commitment to the vision of the program. The opportunity for research and extension collaboration was also requested to assist the program with new research interests and common goals. These partnerships are critical in maintaining the programs commitments to science-based knowledge and application of research.
