When wildfire tore through giant sequoia groves in the Sierra Nevada last year, researchers estimated hundreds of the towering trees — maybe 1,000 — were killed.
Now, almost nine months later, experts have revised that figure tenfold. A new draft report puts the toll at 7,500 to 10,600 trees — 10% to 14% of the world’s natural population.
