That’s exciting that you have initiated a PhD on wildfire! Congrats! This is a tough question because it just depends on where you look! In longleaf pine ecosystems of the Southeast, for example, our tree-ring records show us that we need more fire on the landscape. We need to continue our prescribed burning and increase it in many areas. There are some locations where fire activity has changed in recent years, related to climate change and the history of fire exclusion (including fire suppression). In some places, fires are happening more frequently than historically, based on comparisons to the tree rings and other proxy records.
