The Bulkley Valley Research Centre hosted a dynamic conference in February of 2007, attracting some of the province’s top forestry professionals as well as prominent researchers from Alberta and the United States.

This conference was organized as a way for researchers, managers, silviculturists, and other practitioners to update themselves on current developments in the science of managing complex forest stands.  In the past 5 years there have been substantial advances in our understanding of complex stand dynamics, in our knowledge of non-timber values, and in an array of simulation models and decision support tools to support decision-making around complex stands.  Much of this is driven by the current mountain pine beetle epidemic.  Such models continue to be modified and improved.  This conference and proceedings is a way to distribute this information more broadly.

Our definition of ‘complex stands’ for this conference is fairly simple.  ‘Complex stands’ have: multiple tree species, species of multiple ages, multiple layers, a variety of other organisms, and are managed for multiple values.

The first day offered different perspectives on complex stand management.  The second day focused on active research projects addressing some of the questions and challenges with which researchers are faced. The three main topic areas were 1) research on complex stands and succession; 2) management and research related to mountain pine beetle; and 3) growth models and decision support tools for complex stand management.

This conference was followed by a two day SORTIE-ND workshop that introduced foresters and technicians to the latest software that will offer the industry an innovative approach to modeling complex stand structures.

Thank you to Chief Woos (Roy Morris) and the Wet’suwet’en for hosting this event on their territories, and for the traditional welcome.

This conference was made possible by the Forest Investment Account - Forest Sciences Program.  We would like to thank all conference presenters as well as participants in making this conference a great success!
