“…Analyses conducted within the northwest (Figure 1, region b) and central RIA study area (Figure 1, region c) revealed that regions that are already characterized by a relatively short fire interval and low productivity will be increasingly vulnerable to regeneration failure with changes in burn rate (Splawinski et al 2019a,c, Cyr et al 2021, Forestier en Chef 2021a), with regeneration failures that could cover more than 30% of the territory by 2100 under RCP 8.5 (Figures 4i and 4ii). Such changes will promote an important switch from boreal forest landscapes to unproductive open woodlands (Splawinski et al 2019a, hindering the recruitment of trees and maintaining low stand density over time (Splawinski et al 2018) that could in turn alter future timber harvesting. In this context, we assessed the joint impact of climate-induced increases in burn rates as well as harvest on various productivity variables in these two regions.…”

Regional analyses assessing the vulnerabilities of forest ecosystems and the forest sector to climate change are key to consider the heterogeneity of climate change impacts but also the fact that risks, opportunities and adaptation capacities might differ regionally. Here we provide the Regional Integrated Assessment of climate change on Quebec’s forests, a work that involved several research teams and that focused on climate change impacts on Quebec’s commercial forests and on potential adaptation solutions. Our work showed that climate change will alter several ecological processes within Quebec’s forests. These changes will result in important modifications in forest landscapes. Harvest will cumulate with climate change effects to further alter future forest landscapes which will also have consequences on wildlife habitat (including woodland caribou habitat), avian biodiversity, carbon budget and a variety of forest landscape values for Indigenous peoples. The adaptation of the forest sector, will be crucial to mitigate the impacts of climate change on forest ecosystem goods and services and improve their resilience. Moving forward, a broad range of adaptation measures, notably through reducing harvest levels, should be explored to help strike a balance among social, ecological and economic values. We conclude that without climate adaptation strong negative economical and ecological impacts will likely affect Quebec’s forests.

“…Although jack pine seedlings generally perform better than black spruce under dry conditions (Sirois 1993;Blake and Li 2003;Hébert et al 2006), they could also be affected by water deficits. Indeed, in an experiment testing different water regimes, no seedlings survived after 3 months in a treatment involving two-fold less frequent watering compared to normal precipitation in eastern Canada (Splawinski et al 2018). Buxton et al (1985) observed that only 33% of jack pine seedlings survived after 9 days of drought, compared with 51% survival for black spruce.…”

Climate change is projected to increase fire severity and frequency in the boreal forest, but it could also directly affect post-fire recruitment processes by impacting seed production, germination, and seedling growth and survival. We reviewed current knowledge regarding the effects of high temperatures and water deficits on post-fire recruitment processes of four major tree species (Picea mariana, Pinus banksiana, Populus tremuloides and Betula papyrifera) in order to anticipate the effects of climate change on forest recovery following fire in the boreal biome. We also produced maps of future vulnerability of post-fire recruitment by combining tree distributions in Canada with projections of temperature, moisture index and fire regime for the 2041-2070 and 2071-2100 periods. Although our review reveals that information is lacking for some regeneration stages, it highlights the response variability to climate conditions between species. The recruitment process of black spruce is likely to be the most affected by rising temperatures and water deficits, but more tolerant species are also at risk of being impacted by projected climate conditions. Our maps suggest that in eastern Canada, tree species will be vulnerable mainly to projected increases in temperature, while forests will be affected mostly by droughts in western Canada. Coniferdominated forests are at risk of becoming less productive than they currently are, and eventually, timber supplies from deciduous species-dominated forests could also decrease. Our vulnerability maps are useful for prioritizing areas where regeneration monitoring efforts and adaptive measures could be developed.
