California forest fires threaten world’s largest trees

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.

Multiple forest fires are threatening groves of gigantic sequoias in California’s Sierra Nevada mountains that are home to some of the world’s largest trees.

Flames are likely to reach the famous Giant Forest in Sequoia National Park, where two fires have been burning since lightning ignited them on September 9, according to a briefing for fire crews.
