Rapid rise in wildfires in large parts of Canada?
Date:12/16/2011

Chicago/Leipzig. Large forest regions in Canada are apparently about to experience rapid change. Based on models, scientists can now show that there are threshold values for wildfires just like there are for epidemics. Large areas of Canada are apparently approaching this threshold value and may in future exceed it due to climate change. As a result both the area burnt down annually and the average size of the fires would increase, write the researchers of the Helmholtz Centre for Environmental Research (UFZ) and the University of Michigan in the December issue of the journal the American Naturalist. The strategies for combating wildfires in large parts of Canada should therefore be reconsidered.

According to media reports, after weeks of drought around 1,000 hectares of forest and scrubland were burnt down in the West Canadian province British Columbia in the summer of 2009 alone. 11,000 people had to be evacuated. Are such events on the rise as a result of climate change? This question is being hotly debated by ecologists all over the world. In July a group of US researchers led by Anthony Westerling of the University of California forecasted similar changes in the journal PNAS. They believe that climate change might result in a dramatic increase in the threat of wildfires in Yellowstone National Park and that the forests might disappear here in the 21st century.

Fires are an important factor in many terrestrial ecosystems. They are a result of the interaction of the weather, vegetation and land use, which makes them very sensitive to global change. "Changes in the wildfire regime have a significant impact on a local and global scale and therefore on the climate as well. It is therefore important to understand how the mechanisms which shape these wildfires work in order to be able to make predict
