Boreal Mixedwoods 2012– Ecology and Management for Multiple Values

 

June 17-20, 2012

 

 

 

 

 

 

  Delta Edmonton South, Edmonton, Alberta

 

 

 

 

 

 

 

Mixedwood forests are an ecologically and economically prominent and important component of Canada’s boreal forest.  A wealth of knowledge relating to the ecology and management of boreal mixedwood forests has been developed over the past 20 years, by researchers and forest managers.

 

 

The Boreal Mixedwoods 2012 conference provided a forum for presentation and discussion of current knowledge relating to the ecology and management of mixedwood stands and landscapes to achieve ecological, social and economic objectives. This included evolving opportunities to improve the value of products being produced from these forests.

 

The conference was hosted by the Canadian Wood Fibre Centre and the University of Alberta.  The program included invited keynote speakers, volunteer papers, discussion sessions, and a volunteer poster session.

 

We are grateful to everyone who helped with the organization of this event and to everyone who participated.
