Peatland burning identification among other wildfires across different ecozones in Canada
Bibliographic record
Abstract
The unprecedented severity of the 2023 Canadian wildfires highlights growing concerns about the vulnerability of global peatlands—key ecosystems storing substantial amounts of terrestrial carbon. Peatlands, traditionally resistant to burning, are increasingly at risk due to climate-induced warmer and drier conditions. This study specifically investigates the extent and characteristics of peat burning in the 2023 Canadian wildfires based on available remote sensing data. The primary objective is to determine whether fires on peatlands demonstrate distinct fire behavior compared to fires on non-peatland. To achieve this goal, this study utilized statistical tools and machine learning algorithms, including power-law relationship estimates, Mann-Whitney U test, K-means clustering, and generalized additive model (GAM) to identify the contribution of peat presence to fire behaviors. Key findings demonstrate that fires on peatland are significantly more intense, longer-lasting, and associated with higher carbon emissions. Even though peat combustion can not be confirmed without field validations, these results underscore the critical importance of the potential impact of peat on wildfire growth and management. By highlighting the disproportionate impact of peat burning, this study provides a foundation for future research aimed at developing targeted remote sensing techniques and policy responses to mitigate peatland vulnerability and preserve vital carbon stores in the context of global climate change.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
