California wildfires threaten famous giant sequoia trees
Firefighters wrapped the base of the world's largest tree in a fire-resistant blanket as they tried to save a famous grove of gigantic old-growth sequoias from wildfires burning on Sept. 16 in California's rugged Sierra Nevada.
The colossal General Sherman Tree in Sequoia National Park's Giant Forest, some other sequoias, the Giant Forest Museum and other buildings were wrapped as protection against the possibility of intense flames, fire spokeswoman Rebecca Paterson said.
The aluminum wrapping can withstand intensive heat for short periods. Federal officials say they have been using the material for several years throughout the U.S. West to protect sensitive structures from flames. Near Lake Tahoe, some homes that were wrapped in protective material survived a recent wildfire while others nearby were destroyed.
The Colony Fire, one of two burning in Sequoia National Park, was expected to reach the Giant Forest, a grove of 2,000 sequoias, at some point within days. It was unclear Thursday night whether that had happened. The fire didn't grow significantly as a layer of smoke reduced its spread, fire spokeswoman Katy Hooper said.
It comes after a wildfire killed thousands of sequoias, some as tall as high-rises and thousands of years old, in the region last year.
The General Sherman Tree is the largest in the world by volume, at 52,508 cubic feet (1,487 cubic meters), according to the National Park Service. It towers 275 feet (84 meters) high and has a circumference of 103 feet (31 meters) at ground level.
Sequoia and Kings Canyon national parks Superintendent Clay Jordan stressed the importance of protecting the massive trees from high-intensity fire during a briefing for firefighters.
