Fire affects forests above and belowground. Travel along on a multiscale journey from forest-wide influences to molecular-level changes, unraveling the knowns and unknowns of fire effects on soil, vegetation, and carbon.
Sharon Hood explains how fire affects tree mortality, tracing the pivotal role of carbohydrates in a tree's post-fire survival. Dexter Strother investigates the production and persistence of black carbon in soils, shedding light on its potential climate implications. Matt Dickinson shares innovative techniques for measuring belowground heat transfer during fires, and unveils the intricate effects on soil nutrients and microbial life.
