Postglacial establishment and expansion of marginal populations of sugar maple in western Québec, Canada
An isolated sugar maple ( Acer saccharum Marsh.) stand is located in the boreal forest of Abitibi, about 75 km beyond its present northern range limit. When did this relatively thermophilous tree species establish after ice retreat? Were its populations more abundant than now sometimes in the past? If so, when and how did they expand then retracted? How did the species persist in boreal forest over time? What could have been the role of fire on t…
Projected changes in fire activity and severity feedback in the spruce–feather moss forest of western Quebec, Canada
As a result of extreme weather conditions associated with anthropogenic climate change, fire regimes are expected to continue to change in the boreal forest over the 21st century and beyond. Consequently, changes in ecological attributes like stand composition, tree density and forest carbon stock can be expected. In the present study, we used an adjusted version of the CanFIRE model to project long-term (1971–2100) changes in burn rates, fire se…
The reconstruction of burned area and fire severity using charcoal from boreal lake sediments
Although lacustrine sedimentary charcoal has long been used to infer paleofires, their quantitative reconstructions require improvements of the calibration of their links with fire regimes (i.e. occurrence, area, and severity) and the taphonomic processes that affect charcoal particles between the production and the deposition in lake sediments. Charcoal particles >150 μm were monitored yearly from 2011 to 2016 using traps submerged in seven head…
Spatiotemporal evolution of paludification associated with autogenic and allogenic factors in the black spruce–moss boreal forest of Québec, Canada
Paludification is the most common process of peatland formation in boreal regions. In this study, we investigated the autogenic (e.g., topography) and allogenic (fire and climate) factors triggering paludification in different geomorphological contexts (glaciolacustrine silty-clayey and fluvioglacial deposits) within the Québec black spruce ( Picea mariana )–moss boreal forest. Paleoecological analyses were conducted along three toposequences var…
Coherent signature of warming-induced extreme sub-continental boreal wildfire activity 4800 and 1100 years BP
Climate changes are expected to progressively increase extreme wildfire frequency in forests. Finding past analogs for periods of extreme biomass burning would provide valuable insights regarding what the effects of warming might be for tree species distribution, ecosystem integrity, atmospheric greenhouse gas balance, and human safety. Here, we used a network of 42 lake-sediment charcoal records across a ∼2000 km transect in eastern boreal North…
Fire history of the central boreal forest in eastern North America reveals stability since the mid-Holocene
Past and present fire frequencies are key factors to evaluate fire-mediated changes in climate, but this metric is difficult to evaluate realistically in paleoecological and climatic reconstructions. Here, we applied charcoal analysis of forest soils to test from direct evidence the stability and resilience of the eastern North-American boreal forest at the Holocene timescale. Current knowledge indicates that the boreal forest is not so stable an…
Utilisation de la classification de la végétation dans l’aménagement forestier au Québec
Le Ministère des Ressources naturelles et de la Faune du Québec a amorcé un vaste programme de classification écologique du territoire en 1986. Ce programme s’appuie sur une cartographie physique à petite échelle, un inventaire écologique systématique et une classification de la végétation selon des principes de phytoécologie. Une attention particulière a été portée pour bien expliquer la dynamique végétale selon les milieux et les gradients clim…
