However, wildfires in the taiga have increased since the 1990s. It is thought that this is due to global warming, bringing warmer and drier summers. They are becoming larger and more frequent, without giving the forest time to recover.
Why are fires so common in taiga?
In addition to the release of carbon through the melting of permafrost, high intensity wildfires will become more common and thus contribute to the release of stored carbon. This means that the boreal forest and its fire regime is becoming an increasingly more significant factor in determining the global carbon budget.
What is the role of fire in a taiga?
Often ignited by lightning strikes, fires in the boreal region release nutrients essential to forest growth into the soil. Some tree species are even dependent on the heat from fire to disperse their seeds, and the natural burn cycle helps maintain a healthy forest ecosystem.
Are fires good for the forest?
Fire removes low-growing underbrush, cleans the forest floor of debris, opens it up to sunlight, and nourishes the soil. Reducing this competition for nutrients allows established trees to grow stronger and healthier. Fire clears the weaker trees and debris and returns health to the forest.

Why is it important to protect the taiga?
Its home to a rich biodiversity for North America and is central to the lives and cultural practices of over a million indigenous peoples. It also plays an indispensable role in helping us win the fight against climate change.
Are forest fires a bad thing?
It plays a key role in shaping ecosystems by serving as an agent of renewal and change. But fire can be deadly, destroying homes, wildlife habitat and timber, and polluting the air with emissions harmful to human health. Fire also releases carbon dioxide—a key greenhouse gas—into the atmosphere.
Do forests grow back after fire?
Typically, species that regenerate by re-sprouting after theyve burned have an extensive root system. Dormant buds are protected underground, and nutrients stored in the root system allow quick sprouting after the fire.
