Background Recent studies have reported increasing frequency of lightning fires and associated burned area in Tasmania. Aims To identify factors driving the scale lightning-induced Method We compiled datasets on activity, fire, vegetation fuel moisture. Multi-model inference was used to evaluate predictors fire. determined number days annually with dry enough be susceptible fires. examined temporal trends lightning, moisture between 2005 2022. Key results Drier fuels higher density increased probability fires, areas treeless being more than forests. Lightning fire-prone were concentrated western central However, no significant found or fire days. There a drying trend southern Tasmania, wetness northern eastern regions. Conclusions implications are most likely those exposed intense activity. The short record limits detecting trends. High-resolution data dryness, ignitions crucial for understanding dynamics.
