[californiadisasters] Climate & Fires in Different Subregions of California



From Climate Change and Energy to Fires and Fish:

Posted: 06 Aug 2012 06:00 AM PDT

About 4,000 people are expected to attend the annual meeting of the Ecological Society of America in Portland, Ore., Aug. 5-10. The theme of this year's conference is "Life on Earth: Preserving, Utilizing and Sustaining our Ecosystems."

Climate and Fires in Different Subregions of California: When wildfires sweep through news media and current events, there is a tendency to describe them broadly as "wildfires in the western U.S." The truth requires far more nuance. In this talk, USGS Western Ecological Research Center fire ecologist Jon Keeley discusses the subregions of California and contrasts the relationship between fire activity over the past 100 years and changes in climate and in human demography. Surprisingly, in both forested and non-forested subregions, the decade with the highest area burned was the 1920s. In some subregions, the area burned has declined continuously up until the present whereas in other subregions there has been a steady rise in fire activity since the 1970s, with the current decade approaching 1920s level of burning.  A subregional analysis of climate / fire interactions in California will be in Room B114 on Aug. 10 at 8:20 a.m. Contact: Jon Keeley,  jon_keeley@usgs.gov, 559-565-3170.
