Video. NO COMMENT: Health check of a giant sequoia

Researchers from the Ancient Forest Society inspected the General Sherman, a 2,200-year-old giant sequoia in Sequoia National Park, for bark beetle infestations.

These beetles, recently deadly to redwoods, bore into branches and trunks, potentially killing the trees within six months.

Although General Sherman showed no signs of beetle activity, the inspection highlighted threats from climate change, beetles, wildfires and drought that can pose to redwoods.

The Giant Sequoia Lands Coalition must monitor and protect these iconic trees.
