转载：SCI FRI. Science Friday. 201712 8 期

今年10月份，北加州发生了非常严重的森林大火，

时间刚刚过去两个月，目前南加州也发生了非常严重的森林大火。

今天的节目，科学星期五就会讨论为何发生森林大火，如何防治森林大火。

Southern California’s cities are under siege byout-of-control wildfires ripping through hillsides and housing developments. Theblazes in Los Angeles and Ventura counties have forced more than 200,000 peoplefrom their homes, destroyed hundreds of buildings, and threatened thousandsmore. The current fires, along with the catastrophic wildfires earlier thisyear in Sonoma, add up to make 2017 California’s worst year on record forwildfire.

Hugh Safford, a regional ecologist for the U.S. ForestService’s Pacific Southwest Region, talks about the ingredients that triggeredthis year’s devastating wildfire season up and down the state—and discusses whyrestoring native chaparral will be important after the burns.

And Joe Cahill, a botanist and executive director of theVentura Botanical Gardens, says the chaparral scrublands in the garden have“burned totally to the ground.” He talks about the garden’s destruction in theThomas fire, and whether some fire-adapted species may be able to survive.
