Weeping willows are everywhere, but they’re particularly prominent in California’s southern and central Sierra Nevada.
In the past decade, they’ve spread a deadly fungus known as “California tree blight.”
The fungus attacks the delicate, white-capped willow trees that bear the fruit of the California redwood tree, a massive tree with over 30,000 species.
It kills the tree’s bark and leaves and rots the wood, turning it brown, red, and gray.
The trees are the source of a valuable source of timber for California’s agriculture industry.
But now the fungus is threatening to spread to the rest of the state, killing thousands of willows and destroying the livelihoods of thousands of farmers who rely on them for seedlings.
The fungus is the second-deadliest fungus in California, behind the West Nile virus, which kills an estimated 300,000 people a year.
The West Nile is now spreading at a faster rate, and the fungus’s emergence is the main reason California is experiencing its highest number of deaths from the disease since 2000.
But in the past two years, the state has also seen an increase in the number of willow deaths, which have been rising at a rate of nearly 10 percent a year, according to data collected by the California Department of Forestry and Fire Protection.
That’s a huge spike for a disease that is so rare and endemic in California that it can be passed down from one generation to the next.
The outbreak in southern California has left hundreds of farmers dead and destroyed thousands of trees, said Jeff Karp, the director of the Sierra Nevada Forest Service, which is responsible for protecting and managing the forests in Southern California.
The number of California tree blight deaths has more than doubled in just two years.
In recent years, there have been two more outbreaks, with at least three more cases each year.
A third is now suspected to have been a new one.
Karp told me he thinks the fungus has spread more rapidly in recent years because of climate change.
“The climate is warming and that has increased the risk of this fungus becoming more severe,” he said.
“It’s a very difficult disease to control.”
The disease is also spreading faster than ever before.
In a survey released in March, the California State Water Resources Control Board found that nearly 90 percent of the land affected by the disease had not been properly managed since 2008.
The board estimated that 1,300,000 willows were destroyed or lost, and it expects more than 1.4 million trees will be lost.
California has not been immune to the disease.
In 2009, the first year of the outbreak, the Sierra was declared a national emergency.
The last time that happened was during the drought of the early 1990s, when California lost more than a quarter of its trees.
The new outbreak is the latest reminder of how important it is to protect and manage the state’s forests, and its recovery from the past is under the watchful eye of Gov.
Jerry Brown, who has pledged to take more aggressive steps to prevent a resurgence of the disease and restore the environment.
As he prepares to address the state legislature on April 3, Brown has been talking about what he has called “the next big threat” to the state: climate change and the risk that California’s forests will become too dependent on one source of carbon to offset carbon emissions.
Climate change is a problem we’ve known about for a long time, he said in March.
“We can’t be a carbon-rich state.
We can’t afford to be.”
