Juang, C. S. et al. Rapid growth of large forest fires drives the exponential response of annual forestfire area to aridity in the western United States.Geophys. Res. Lett.49, e2021GL097131 (2022). Fire Statistics(Canadian Interagency Forest Fire Centre, accessed 3 November 2023);https:/...
The 2023 Canadian forest fires have been extreme in scale and intensity with more than seven times the average annual area burned compared to the previous four decades1. Here, we quantify the carbon emissions from these fires from May to September 2023 on the basis of inverse modelling of sate...
Forest fires in Canada are directly influenced by the state of the climate system. The strong connection between climate and fire, along with the dynamic nature of the climate system, causes the extent, severity and frequency of fires to change over time. For instance, many reconstructions of ...
In Canada, recent forest disturbance episodes such as insect outbreaks, forest fires, and drought have significant consequences on forest ecosystems while future climate change is expected to result in more severe impacts. These effects of climate change will impact the communities that depend on fore...
scar, and (3) proportional filtering. "Bracketing" fire regime statistics to account for purported uncertainty associated with targeted sampling was not useful. Quantifying differences in sampling approaches cannot resolve all the limitations of fire-scar methods, but does strengthen interpretation of thes...
fires and where fire mitigation is very efficient, logging has almost become the only type of severe-intensity disturbance (Östlund et al.1997). Clearcutting systems are by far the most common harvesting method in the boreal forest biome. This approach is most profitable for forest companies,...
2.6. Bioinformatics and statistics We worked primarily in Jupyter notebooks, with phyloseq (McMurdie and Holmes, 2013), ggplot (Wickham, 2016), and dplyr (Wickham et al., 2019) being instrumental in working with the data in R (R Core Team, 2017) (See Supplemental Note 1 for full bioinfor...
3.1. Preliminary and descriptive statistics of extreme temperatures in the Canadian prairies Fig. 3 shows the mean maximum temperature plot for the Canadian Prairies between 1970 and 2020. The plot shows that the southern portion of this region has a temperature above 36 °C. The region close to...
Native Canadian prairie vegetation has experi- enced a great decrease in area, from 61.5 M ha prior to European settlement to 11.4 M ha in recent years based on Statistics Canada Census 2006 and earlier pub- lished data (Bailey et al. 2010). This is partly due to ...
Farm sizes were larger than the provincial averages of 1237 acres in Alberta and 1784 in Saskatchewan (Alberta Agriculture and Forestry 2017; Statistics Canada 2017d), although sample aver- ages were increased by the participation of several extremely large farms. Similarly, the high average number...
