Torching Yosemite ... with a purpose.
It's fire season again in Yosemite. But this time of year, blazes are more likely to be sparked by park rangers than by Mother Nature. "Prescribed burns," such as this one in Yosemite Valley, are a key element of the national park's updated Fire Management Plan. In the wake of the uncontrollable fire storms that blackened large areas of Yellowstone in 1988, Yosemith's plan was revised to gradually reduce dangerous amounts of undergrowth and dead wood that have built up over a century of fire suppression. Under the plan, natural fires (started mostly by lightning) will be allowed to burn where risk to people or facilities is small. Prescribed burns are planned for more critical areas--such as the valley--only when weather and fuel moisture conditions permit.
