In times of urgency, prescribed burns get an upgrade.
Prescribed burns, an age-old practice that rids forests of the small trees, brush and other matter than can fuel wildfires, are getting a 21st-century upgrade.
Scientists think we can do better. Several teams recently converged at Blodgett Forest Research Station northeast of Sacramento, California, an area thick with towering Ponderosa pine, Douglas fir and incense cedar.
Scientists have been “just completely caught off guard about how fast things are changing,” said James T. Randerson, an earth scientist at the University of California, Irvine. Better fire modeling is important, but so is baking that knowledge into easy-to-use tools for burn crews, he said. “We should be able to represent, in a training environment, what fire should or might do in a very sophisticated way, long before we strike a match.”
In another patch of forest, Randerson and Audrey Odwuor, a doctoral candidate at Irvine, placed twigs and pine needles into Ziploc bags, as if collecting evidence from a crime scene. They planned to burn the material back at their lab to analyze the chemical composition of the resulting emissions. They had also brought instruments to Blodgett to collect smoke samples.
