Upcoming Webinars Date: Friday, May 29, 2026, from 2:00 - 3:00pm ET / 11:00am - 12:00pm PT Title:  Causal Analysis of Fire Regime Drivers Speaker: Jon Keeley, Research Scientist, USGS Western Ecological Research Center Join USGS Senior Scientist Jon E. Keeley for a closer look at how climate and human factors influence wildfire activity. This webinar draws on more than a century of fire records, from 1910 to 2021, combined with climate and weather data to better understand what shapes fire behavior across different ecoregions. The presentation introduces a framework that distinguishes between immediate drivers, such as fuel conditions and ignition sources, and underlying factors like long-term climate patterns and land use. Findings show that wildfire drivers vary widely across California. In northern forested regions, fire activity is closely linked to fuel aridity tied to climate conditions, along with the accumulation of woody fuels influenced by fire suppression.…
