Demonstrating the resistance of the Boreal forest to high burn rates
October 7, 2014

A study by CEN’s researcher Dominique Arseneault, his student Jessie Héon and a colleague, recently published in Proceedings of the National Academy of Sciences US, clearly demonstrates that the time interval between forest fires has an effect on the intensity of successive fires. The recurrence of fires has induced the appearance of many young forests which has in turn created a negative feedback on fire activity given the reduced amount of fuel found in these forests. In the context of climate change and the increased occurrence of draughts, which represent the main cause of forest fires, this new knowledge will be extremely useful in determining the forests which are most at risk of fire and of fast propagation.
