Tree die-off in California is “unprecedented”

“The number of dead trees in California’s drought-stricken forests has risen dramatically to more than 102 million in what officials described as an unparalleled ecological disaster that heightens the danger of massive wildfires and damaging erosion,” the Los Angeles Times is reporting.

“Officials said they were alarmed by the increase in dead trees, which they estimated to have risen by 36 million since the government’s last survey in May. The U.S. Forest Service, which performs such surveys of forest land, said Friday that 62 million trees have died this year alone.

“’The scale of die-off in California is unprecedented in our modern history,’ said Randy Moore, the forester for the region of the U.S. Forest Service that includes California. Trees are dying ‘at a rate much quicker than we thought.’

“Scientists say five years of drought are to blame for much of the destruction. The lack of rain has put California’s trees under considerable stress, making them more susceptible to the organisms, such as beetles, that can kill them. Unusually high temperatures have added to the trees’ demand for water, exacerbating an already grim situation.

“The majority of the dead trees are in the southern and central Sierra Nevada region, officials said, though they warned that high mortality levels are also creeping into forests in Northern California, notably Siskiyou, Modoc, Plumas and Lassen counties.
