istorically, fires have burned in the Sierra every 5 to 15 years. But
now, 100 years of fire suppression has blocked this important process,
a vast accumulation of dead wood and other fuel puts the biggest trees
at risk. Unlike centuries past, needles and limbs from the big trees and
other more flammable species fill the forest floor. Smaller trees that
would have been burned out form a ladder into the upper branches that
allows fire to climb into the crowns of the forest giants like in the
fire shown to the right.
And, Sequoias, some of them 3,000 years old, either reproduce slowly
or never without fire to clear the way.
