Map of fire regimes across the USA

I'm not sure what happened to the thread on fires and their differing impacts in the ADKs that was posted in the "General Adirondack Discussion" section of the forum. The one thing I was going to add to the conversation there was the following map that shows how the natural fire regimes differ across the Adirondack region- as well as across the entirety of the country. ​This was pointed out in that thread but the following map helps to illustrate it:

Of note is that the majority of the central ADKs is classified as having a natural fire regime that consists of "stand replacement fires." This means that when natural fires do occur across the majority of the Adirondack Park, they are nearly always catastrophic events resulting in a complete reset of successional forest dynamics.

In contrast, the fringes of the Adirondack Park- including the Lake Champlain valley- have a natural fire regime that consists of "mixed severity fires." In other words, when fires occur here, the set back in successional dynamics isn't always so severe, and the forest can appear to recover more quickly- especially when compared to the different regime of the higher elevation parts of the ADKs.

As complex as this map looks, it's still very much a generalization. The rabbit hole of differing fire regimes is deep- if you do a google image search for maps of fire regimes across the USA, you find no shortage of Jackson Pollock-inspired graphics.
