"I'm not suggesting one's right and one's wrong, but it presents an interesting contrast," Safford said, "It's a good case study to look at the effects of large, severe fires on watersheds subject to different management regimes."
The fir, cedar, and pine forests of the high Sierra are adapted to frequent fires ignited by lightning. Fire scars on older trees, including the 2000-year-old giant sequoias record a history of low intensity fires recurring every 10 to 20 years. Fires that burned at low intensity through the understory tended to kill few of the mature trees, on the order of 5 to 10 percent. Recent studies have found that wildfires in the mixed conifer forests of the Sierra often run out of fuel and go out when they encounter sections of forest that have already burned within the last decade.
Though it smoldered on into October, by September 3rd, 2013, the Forest Service was reporting that the Rim Fire was 70 percent contained. Most of the acreage burned in the first week. The blaze that began as an alarming, out-of-control monster became just another big fire that managers were using to do ecological work.
Ignited by a hunter's illegal campfire near the Rim of the World Vista in Stanislaus National Forest on August 17th, the fire ultimately burned for three months, consuming 257,314 acres of trees and $127 million taxpayer dollars. Smoke from the fire prompted air quality warnings from the Bay Area to Reno, Nev. It was the largest recorded fire in the Sierra Nevada.
A trend toward mega-fires
In the past few decades, ecologists have noted a trend toward intense
