Prehistoric fire area and emissions from California's forests, woodlands, shrublands, and grasslands
In the majority of US political settings wildland fire is still discussed as a negative force. Lacking from current wildfire discussions are estimates of the spatial extent of fire and their resultant emissions before the influences of Euro-American settlement and this is the…
