In its latest aerial survey released on Friday, the U.S. Forest Service said 62 million trees in California forest died this year, bringing the six-year total to 102 million trees lost.
“It’s not beyond the pale to suggest that this is a pretty unprecedented event in at least recent history,” a US Geological Survey ecologist tells the San Francisco Chronicle.
There are 21 million acres of trees in California’s national forests. The dead trees, some of which can live over 100 years, represent one-third of the trees left. In other words, of the 21 million acres of trees, 7.7 million acres of trees are dead.
