An American tragedy: why are millions of trees dying across the country?

From the Guardian - a quiet crisis playing out in US forests as huge numbers of trees succumb to drought, disease, insects and wildfire – much of it driven by climate change

"Forestry officials and scientists are increasingly alarmed, and say the essential role of trees – providing clean water, locking up carbon and sheltering whole ecosystems – is being undermined on a grand scale.

California and mountain states have suffered particularly big die-offs in recent years, with 66m trees killed in the Sierra Nevada alone since 2010, according to the Forestry Service.

In northern California, an invasive pathogen called Sudden Oak Death is infecting hundreds of different plants, from redwoods and ferns to backyard oaks and bay laurels. The disease is distantly related to the cause of the 19th-century Irish potato famine, and appears to have arrived with two “Typhoid Marys”, rhododendrons and bay laurels, said Dr David Rizzo, of the University of California, Davis.

“We’re talking millions of trees killed, whole mountain sides dying,” Rizzo said."
