Forest Succession Underway, Continuing

Survey Finds 18 Million Trees Died in California in 2018,
US Forest Service, Feburary 11, 2019.


Tree Mortality Continues
“The USDA Forest Service announced today that an additional 18 million trees, mostly conifers, died in California since fall 2017.”

California Count
“Over 147 million trees have died across 9.7 million acres of federal, state, local and private lands in California since the drought began in 2010.”

Over, but Extreme Weather Continues...
“While the 2016-2017 winter officially ended California’s drought, below-average precipitation recorded in 2017-2018 slowed the recovery of the state’s surviving trees.”

Burn it Controlled, Now, before Nature (or PGE) Burns It
“The Forest Service completed approximately 313,000 acres of restoration in 2018, which included over 63,000 acres of prescribed fire—the largest number recorded since the National Fire Plan was implemented in 2001.”

“Years of drought and a bark beetle epidemic have caused one of the largest tree die-offs in state history.”
