New WUI areas have expanded by more than 46 million acres
(33%) over the 1990-2010 period
WUI areas now include 1/3 of all homes in the US within 10% of
the nation's land area
The population growth in at-risk areas for wildfires will require
more aggressive firefighting strategies
Growth in the WUI and increasing global temperatures have led
to the average number of large fires (larger than 1,000 acres)
burning in the Western US each year to more than triple
between the period of 1970s to 2010s
Total number of Western US acres burned by such fires showed a
six-fold increase in the 2010s compared to the 1970s
Dixie (CA, 2021) and August Complex (CA, 2020) were two of the
most historically damaging wildfires, burning a combined ~2
million acres
