"Last week, General Sherman, California's most famous giant sequoia, got a checkup.
Climbers from the Ancient Forest Society scaled the tree looking for signs of a sequoia bark beetle infestation — entrance holes where adults had burrowed into the branches and laid their eggs; exit holes, where larvae chewed their way out; globules of pitch, indicating the tree was putting up a fight, trying to push the beetles out.
And, simply, whether Sherman's canopy looked healthy.
The beetles can kill a tree within a year, starting at the top and working their way down over several generations. Feeding on the cambium, they can interrupt the tree's ability to distribute water and nutrients. "
