Solomon Dobrowski, Landscape Ecology Professor, University of Montana

The Big Burn of 1910: The spark of today’s wildfire crisis.

Over two days, the ‘Big Burn’ would decimate 3 million acres, kill 87 people, level entire towns, and later shape US policy and approaches to managing wildfire to this day. Solomon will share the story of this event, how its legacy altered the character of forests across the west, and how it continues to shape our ongoing struggle with the wildfire crisis. Solomon, a Cal Forestry alum and landscape ecology professor at the University of Montana, researches climate risks to forests, wildfire, and conservation biogeography. He serves on the USGS Northwest Climate Adaptation Science Center leadership team and advises Blue Forest.
