We use a tree-ring network from southeastern Australia to reconstruct the number of high fire-danger days in January–March, as reflected in the Forest Fire Danger Index (FFDI). Highest quality reconstructions in southwestern Tasmania indicate that the recent persistent increase in seasonal fire danger is unmatched over the past 430 years.

We explore the utility of next-generation satellite observations of fire intensity during the Black Summer Fires. We found that these new datasets capture similar patterns to the previous generation earth-observation data but offer greater temporal detail. These results are significant as they open new opportunities for active fire monitoring.

This study analysed loss data from the 2018 Camp fire and found numerous building characteristics that were important determinants of structural survival, including double paned windows, enclosed eaves, ignition-resistant roofs/siding, age of structure, lack of vents, improvement value, and decks. Defensible space had only weak associations with structure loss in this data set. Mobile homes were far more likely to be destroyed.

Peatlands need acidic soil conditions for maintaining proper health and functioning. Wildfire-produced ash is often alkaline, thus potentially impacting soil pH. We observed that soil pH was not affected by the ash generated during a peatland wildfire.
