History of fire and drought shapes the ecology of California, past and future
Date:8/6/2014

Fire season has arrived in California with vengeance in this third year of extended drought for the state. A series of large fires east of Redding and Fresno, in Yosemite, and on the Oregon border prompted Gov. Jerry Brown to declare a state of emergency on Sunday, August 3rd.

As force of destruction and renewal, fire has a long and intimate history with the ecology of California. Ecological scientists will discuss aspects of that history in detail at the upcoming 99th Annual Meeting of the Ecological Society of America on August 10 15th, 2014.

"Big fires today are not outside the range of historical variation in size," said Jon Keeley, an ecologist based in Three Rivers, Cal., with the U.S. Geological Survey's Western Ecological Research Center, and a Fellow of the Ecological Society.

Keeley will present research on the "association of megafires and extreme droughts in California" at the Annual Meeting as part of a symposium on understanding and adapting to extreme weather and climate events.

He will synthesize his research on the history of wildfire across the entire state, contrasting historical versus contemporary and forested versus non-forested patterns of wildfire incidence. He and his colleagues reviewed Forest Service records dating to 1910, as well as a wealth of newspaper clippings, compiled by a Works Progress Administration archival project, that stretch back to the middle of the last century.

Understanding historical fire trends, Keeley said, means recognizing that when we talk about wildfire in California we are talking about two very different fire regimes in two different ecosystems: the mountain forests and the lower elevation chaparral, oak woodlands, and grasslands.
