Coupling of climate projections with records of area burned over the last 3 decades across the North American boreal zone suggests that area burned will increase by 30-500% by the end of the 21th century, with cascading impacts on ecosystem dynamics and on the boreal carbon balance. Fire size and the frequency of large-fire years are expected to increase. However, how fire size and time since previous fire will influence future burn rates is poorly understood, mostly due to incomplete records of past fire overlaps. Here, we reconstruct the length of overlapping fires along a 190-km long transect over the last 200 years in one of the most fire-prone boreal regions of North America in order to document how fire size and time since previous fire will influence future fire recurrence. We provide direct field evidence that extreme burn rates can be sustained by a few occasional droughts triggering immense fires. However, we also show that the most fire-prone areas of the North American boreal forest are resistant to high burn rates due to overabundant young forest stands, thereby creating a fuel-mediated negative feedback on fire activity. These findings will help refine projections of fire impacts on boreal ecosystems and their large carbon stocks.\r\n","author":{"name":"Jessie Héon, Dominique Arseneault, Marc-André Parisien"},"citation":"Jessie Héon, Dominique Arseneault, Marc-André Parisien. 2014.

The study has been designed so as to reconstruct the extent of wildfires that have overlapped over the last 200-300 years along a 190-km transect. The transect corresponds to the James Bay road in northern Québec and is subdivided into 93 cells of about 2 km2. Samples are trunk cross-section mostly taken on fire-scarred trees, or to a lesser degree, near the base of unscarred specimen. \r\n\r\nNote: On September 23, 2014, carbb001.txt, carbb001-pnas2014-09316dataset-s1.csv, and carbb001-pnas2014-09316dataset-s1.xls were modified as follows:\r\nColorado spruce and blue spruce were replaced with black spruce; \r\nPicea pungens Engelman was replaced with Picea mariana (Mill.)
