That’s a great question! With the understanding that in many places there is a fire deficit on the landscape, there is quite a bit of interest right now in cultural burning across the US / globe. Tree rings and fire scars don’t specifically provide information about how the fires were started, but inferences can be made in some cases. My work into understanding the seasonal aspects of fire scars can help to provide clues about the origins of fires. When we see fire scars that indicate the tree scarring occurred outside of typical wildfire season(s), we can often make assumptions that those fires were anthropogenic in origin. We consider burning by indigenous people to be an important part of the historical fire regime in many locations.
