“After a devastating wildfire season, Canada has experienced a staggering number of forest fires in 2023. These fires have burned an unprecedented 18.5 million hectares of land, which is equivalent to 46 million acres. This accounts for about five percent of Canada’s entire forest area and is more than ten times the amount of land burned in the previous year. Currently, there are still 769 active fires throughout the country, with 345 considered to be ‘out of control.’ The impact of these fires has been immense, with all 13 provinces and territories affected, tens of thousands evacuated, and the loss of at least four firefighters.
The question that arises after such a widespread disaster is what happens to the land and forests once the fires have been extinguished and communities have returned? Forest ecosystems in Canada are fire-adapted, and historically, wildfires have played a role in the natural lifecycle. Fires trigger new growth, reduce diseases, and cleanse the forest floor. After a fire, forests go through a process of regeneration that typically takes several years. It is a natural ecosystem process that cannot and should not be completely excluded from forests, according to David Martell, a professor emeritus at the University of Toronto’s Faculty of Forestry.
Different fire behavior and impacts on forest ecosystems can be observed across the country due to variations in the local environment. Some tree species, such as Jack and Lodgepole pine, actually rely on the heat of a fire to release their seeds. In the aftermath of a fire, aspens and coniferous trees eventually take over, attracting various animal species that benefit from the new growth. This natural process has been a part of the Canadian ecosystem for centuries.
However, climate change is now disrupting this natural cycle. Warmer temperatures are drying out the forests, turning them into tinderboxes vulnerable to ignition. A recent study found that human-caused climate change has more than doubled the likelihood of extreme fire weather conditions in eastern Canada. As a result, the frequency, severity, and intensity of wildfires are increasing, and the boreal forests, one of the largest intact ecosystems on Earth, may be permanently altered.
Edward Struzik, author of ‘Dark Days at Noon: The Future of Fire,’ highlights the potential consequences of these intensifying fires. In some areas, fires are burning so hot that they destroy seeds and nutrients necessary for regrowth. Instead of natural regeneration, these burned areas may transform into deciduous forests or even grasslands. Furthermore, Canada’s boreal forest, which currently serves as a carbon sink, holding a significant portion of the world’s carbon reserves, is now becoming a carbon source. The carbon released from the forest contributes to climate change, fueling the conditions for more fires in a vicious cycle.
Struzik emphasizes the need for new strategies to address this evolving fire situation. He advocates for a coordinated national wildfire strategy involving all levels of government, Indigenous communities, and businesses. Restoration efforts, Indigenous-led prescribed burning, and rethinking infrastructure to minimize fire risks are essential components of moving forward.
As this unprecedented wildfire season comes to a close, it is crucial to reflect on the long-term implications and take action. This requires long-term thinking, investments, and collaboration among various stakeholders. The time to act is now, as the future of Canada’s forests and the planet’s climate depend on our ability to adapt and find innovative solutions.”
