‘Tinderbox’: 20% of California’s forests might die – research
A lead scientist for the Carnegie Airborne Observatory spent three weeks flying over California’s forests in Sacramento and Bakersfield in order to laser map them.
The results were shocking: up to 20 percent of the state’s forests are at risk of dying. The results come as California endures its fourth year of drought and its worst forest fire season in history.
The Carnegie team used a special plane outfitted with two special instruments with which they could map millions of trees a day – a LiDAR and an image spectrometer. The LiDAR fires two lasers out of the bottom of the plane that capture 3D images of the forest, and the image spectrometer measures the chemical makeup of trees. The instruments allowed Carnegie’s Greg Asner to rapidly measure trees in bulk – about 8 million per hour – rather than having to measure individual trees by hand.
