Forest Management and the Dixie Fire Video

by

This video shows how a major wind event in early August, 2021, created extreme fire behavior west of Chester, California. We use satellite-derived forestry data to investigate whether past forest management had any effect on survival of trees in the approximately 100,000-acre area affected by the firestorm. This video is focused on forest conditions and fire behavior in the area around Chester and Swain Mountain. Fire behavior throughout the almost 1,000,000 acre Dixie Fire had a large amount of variety.

We’ll look at other parts of the fire in other videos. This video is a production of The Lookout (the-lookout.org), a user-supported wildfire journalism and education initiative run by Zeke and Erika Lunder, in Chico, California.
