Publication summary: 

We characterized fire-regime components (frequency, size, severity, seasonality and cause) along climate gradients and a gradient of human influence. Fire size, frequency, burn severity and cause were interrelated, whereas humans influenced patterns of burn severity and ignition cause. Wildfire activity was highest where thermal and moisture gradients converge to promote fuel production, flammability and ignitions. Thus, future changes to climate may lead to ecological changes through altered fire regimes.
