California wildfires threaten the world's largest tree
Firefighters in California are trying to save the world's largest trees, threatened by wildfires that have raged for weeks in Sequoia National Park. Writes about it with the BBC.
Этот парк известен своими гигантскими секвойями, включая восьмидесятиметрового гиганта «Генерала Шермана» — самое большое по объему древесины дерево на Земле.
Its age is estimated at 2300-2700 years.
Firefighters use fire retardant aluminum sheeting to protect the General Sherman's trunk and other trees.
Forest fires threaten XNUMX giant sequoias. The fire element is caused by prolonged drought and hot weather in California.

The thick bark of giant sequoias is fire resistant, so these trees are not afraid of ground fires, experts say. But the current fires are not one of them, since they can destroy trees.
The age of giant sequoias can exceed 3 thousand years, and their height reaches 100 meters.

Dixie fire — крупнейший лесной огонь сезона пожаров 2021 года и второй по величине в зарегистрированной истории штата. Стихия сожгла как минимум 388 000 гектаров земли, в основном засаженной деревьями, и разрушила более 1200 зданий на своем пути. Пожар, названный в честь дороги, по которой он прокатился, начался 13 июля в каньоне Фезер-Ривер, пишет Sci tech daily.
As thousands of rescuers continue to fight the fire element, some have been distracted to help curb the nearby Caldor fire that threatened communities near Lake Tahoe before it crossed the state border into Nevada.

However, the smoke affected air quality in the United States and Canada, where it was much closer to the surface.
