Forest Ecology and Management


Forest Ecology and Management is a recognized area of excellence in our department and includes intensive forest management systems, genetic improvement, site preparation, fertilization, pest impact reduction, and density management for enhanced productivity. We are also working on extensive systems such as mixedwood management and emulation of natural processes. Complementary research for all forest management systems ensures that they are ecologically and socially sustainable.
