Pyrodiversity or variation in spatio-temporal fire patterns is increasingly recognized as an
important determinant of ecological pattern and process, yet no consensus surrounds how
best to quantify the phenomenon and its drivers remain largely untested. We present a
generalizable functional diversity approach for measuring pyrodiversity, which incorporates
multiple fire regime traits and can be applied across scales. Further, we tested the
socioecological drivers of pyrodiversity among forests of the western United States. Largely …
