California Now Has More Than 100 Million Dead Trees

California Now Has More Than 100 Million Dead Trees

The USDA announced today that the U.S. Forest Service has identified an additional 36 million dead trees across California since its last aerial survey in May 2016.


This brings the total number of dead trees since 2010 to more than 102 million on 7.7 million acres of California’s drought stricken forests.

In 2016 alone, 62 million trees have died, representing more than a 100% increase in dead trees across the state from 2015. Millions of additional trees are weakened and expected to die in the coming months and years.

With public safety as its most pressing concern, the U.S. Forest Service has committed significant resources to help impacted forests, including reprioritizing $43 million in California in fiscal year 2016 to conduct safety-focused restoration along roads, trails and recreation sites.

However, limited resources and a changing climate hamper the Forest Service’s ability to address tree mortality in California. Agriculture Secretary Tom Vilsack and Forest Service officials said they are seriously hampered not only by short-term budgets passed by Congress, but also a broken budget for the Forest Service. An increasing amount of resources is going to firefighting while less is invested in restoration and forest health, said Vilsack.

“These dead and dying trees continue to elevate the risk of wildfire, complicate our efforts to respond safely and effectively to fires when they do occur, and pose a host of threats to life and property across California,” said Vilsack. “USDA has made restoration work and the removal of excess fuels a top priority, but until Congress passes a permanent fix to the fire budget, we can’t break this cycle of diverting funds away from restoration work to fight the immediate threat of the large unpredictable fires caused by the fuel buildups themselves.”

The majority of the 102 million dead trees are located in 10 counties in the southern and central Sierra Nevada region. The Forest Service also identified increasing mortality in the northern part of the state, including Siskiyou, Modoc, Plumas, and Lassen counties.

Five consecutive years of severe drought in California, a dramatic rise in bark beetle infestation and warmer temperatures are leading to these historic levels of tree die-off. As a result, in October 2015 California Governor Jerry Brown declared a state of emergency on the unprecedented tree die-off and formed a Tree Mortality Task Force to help mobilize additional resources for the safe removal of dead and dying trees.

This year, California had a record-setting wildfire season, with the Blue Cut fire alone scorching more than 30,000 acres and triggering the evacuation of 80,000 people. In the Southeastern U.S., wildfires have burned more than 120,000 acres this fall. The Southeast region of the Forest Service is operating at the highest preparedness level, reflecting the high level of physical resources and funding devoted to the region. Extreme drought conditions persist, and many areas have not seen rain for as many as 95 days.

Longer, hotter fire seasons where extreme fire behavior has become the new norm, as well as increased development in forested areas, is dramatically driving up the cost of fighting fires and squeezing funding for the very efforts that would protect watersheds and restore forests to make them more resilient to fire. Last year fire management alone consumed 56% of the Forest Service’s budget and is anticipated to rise to 67% by 2025.

As the situation in the Southeast demonstrates, the problem of shrinking budget capacity is felt across the U.S., not only in the western states. The health of our forests and landscapes are at risk across the nation, and the tree mortality crisis could be better addressed if not for the increasing percentage of the Forest Service budget going to fight wildfire.

“We must fund wildfire suppression like other natural disasters in the country,” says Vilsack.

Forest Service scientists expect to see continued elevated levels of tree mortality during 2017 in dense forest stands, stands impacted by root diseases or other stress agents and in areas with higher levels of bark beetle activity.

Gosh, maybe consider harvesting trees for lumber, thus employing thousands and creating uncountable free market jobs?

Dave Alden says:

That is a huge amount of trees. It seems like there could be a some sort of plan to log grids of forest and while taking out the effected trees it would also build big swaths of buffer zones to create fire breaks. That way if fire were to break out, the effected grid might burn but not the whole dang forest, like happens now. Possibility, Right?

In the Tahoe area the dead trees are predominantly white fir, which expanded their range considerably during unusually wet conditions from the 50’s to 70’s. They are no good for lumber and marginal for firewood. It is not surprising that they should suffer dieback in a return to more normal conditions.

Patriot says:

Mature forest is 30 trees per acre. Maybe 40 feet apart. The Donner Party came over in wagons weaving around the trees. Impossible now. Trees shade out run out of water from competition. Get the Feds out and let the State manage like they are in Balch Park area.

patriot says:

start thinning the forests. they are trying to save single species for the system. get the cattle back to keeping the system thinned as well in the west.

Bill walker says:

Did they ever think of harvesting? And replanting little trees less water less fires and commerce for poor countries

Judi says:

It’s amazing how we all seem to have the same logical answers to these problems, however the huge overpowered hand of the EPA are strangling every effort. While they think they’re saving the forest & allowing nature to take care of things, the truth is that it’s just perpetuating the problem since the beetles continue to spread from dead trees to live ones. Gettem out of there & use the wood for something useful
