California wildfire could threaten giant trees

Sequoia National Park was shut down and its namesake gigantic trees were potentially threatened Tuesday as two forest fires burned in steep and dangerous terrain in California’s Sierra Nevada. Both fires were projected to advance in the direction of Giant Forest, home to more than 2,000 giant sequoias including the General Sherman Tree, the largest tree on Earth by volume. The massive sequoias grow on the western slope of the Sierra Nevada. The General Sherman Tree stands 275 feet (83.8 meters) and is over 36 feet (11 meters) in diameter at the base, according to the U.S. National Park Service.

“There’s no imminent threat to Giant Forest but that is a potential,” said Mark Ruggiero, fire information officer for Sequoia and Kings Canyon national parks. Ruggiero estimated that the closest flames were about a mile (1.6 kilometres) from the grove. Sequoia headquarters personnel, about 75 people, were being evacuated, he said. The Colony and Paradise fires, named for locations where they started, were ignited by lightning last week and were being battled collectively under the name of the KNP Complex. Their combined sizes grew to more than 4.7 square miles (12 square kilometres).

All park facilities were already closed and wilderness trailhead permits had been cancelled. The Silver City retreat and the summer cabins of Cabin Cove were under evacuation orders. Part of the community of Three Rivers outside the park entrance was under an evacuation warning. Kings Canyon National Park, to the north of Sequoia, remained open.
