SACRAMENTO, Calif. — Admirers of California’s Sierra Nevada mountains are familiar with the swaths of blackened trees flanking its sprawling green forest ranges. A new University of California, Berkeley study quantifies that devastation, finding nearly a third of southern Sierra conifer forests have died in the last decade.
California has seen devastating bouts of drought and record-breaking wildfire events in the last several years. From 2011-2020, a combination of fire, drought and drought-related bark beetle infestations killed 30% of forests in the Sierra Nevada mountain range between Lake Tahoe and Kern County, according to the analysis.
“It’s kind of a wake up call, even to those of us that are kind of steeped in this field,” said Zackary Steel, lead author of the study. “We’re moving from knowing this is a problem to quantifying the problem.”
