Answer:
A typical fire regime for a boreal forest might have fire re-occurring every 53 years.
Explanation:
The fires caused in the boreal region adds essential nutrients to 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. On average, wildfires burn anywhere between 5 to 20 million hectares of boreal forest each year. In Russia, low to moderately intense surface-level fires return every 53 years; for Canada, the return interval is roughly 180 years.
