This is a really good interactive article on how North America is a "fire continent" and that wildfire behavior prior to European colonization was very different than it is today due to changes in land management practices.
It's a blessing and a curse in that many regions have experienced a relatively quiet century or so of limited fire activity. But the absence of fire combined with climate change means these regions will see more fire over the decades to come.
