“World’s largest tree wrapped
in aluminum blanket as wildfire races toward historic Giant Forest”
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 Thursday 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. A 50-year history of using prescribed burns — fires set on
purpose to remove other types of trees and vegetation that would otherwise feed
wildfires — in the parks’ sequoia groves was expected to help the giant trees
survive by lessening the impact if flames reach them. A “robust fire history of
prescribed fire in that area is reason for optimism,” Paterson said.
“Hopefully, the Giant Forest will emerge from this unscathed.” Giant sequoias
are adapted to fire, which can help them thrive by releasing seeds from their
cones and creating clearings that allow young sequoias to grow. But the
extraordinary intensity of fires — fueled by climate change — can overwhelm the
trees. That happened last year when the Castle Fire killed what studies
estimate were 7,500 to 10,600 large sequoias, according to the National Park
Service. A historic drought and heat waves tied to climate change have made
wildfires harder to fight in the American West. Scientists say climate change
has made the region much warmer and drier in the past 30 years and will
continue to make weather more extreme and wildfires more frequent and
destructive.
A national interagency fire
management team took command of efforts to fight the 11.5-square-mile
(30-square-kilometer) Paradise Fire and the 3-square-mile (8-square-kilometer)
Colony Fire, which was closest to the grove. Operations to burn away vegetation
and other fuel that could feed the flames were done in that area. The fires
forced the evacuation of the park this week, and parts of the town of Three
Rivers outside the main entrance remained evacuated Thursday. A bulldozer was
cutting a line between the fire and the community. To the south, a fire on the
Tule River Indian Reservation and in Giant Sequoia National Monument grew
significantly overnight to more than 6 square miles (15 square kilometers), and
crews had no containment of it, a Sequoia National Forest statement said. The
Windy Fire, also started by lightning, has burned into part of the Peyrone
Sequoia Grove in the national monument, and other groves were threatened. “Due
to inaccessible terrain, a preliminary assessment of the fire’s effects on
giant sequoia trees within the grove will be difficult and may take days to
complete,” the statement said. The fire led the Tulare County Sheriff’s Office
to warn the community of Johnsondale and Camp Whitsett, a Boy Scouts camp, to
be ready to evacuate if necessary. The wildfires are among the latest in a long
summer of blazes that have scorched nearly 3,550 square miles (9,195 square
kilometers) in California, destroying hundreds of homes. Crews had limited
ground access to the Colony Fire and the extreme steepness of the terrain
around the Paradise Fire prevented it completely, requiring extensive aerial
water and flame-retardant drops on both fires. The two fires were being managed
collectively as the KNP Complex.

that close and the tree will survive. ^
