UnDisciplined: Is human intervention necessary to regenerate forests after a wildfire?
Remember the smoke that engulfed Salt Lake Valley last summer? Landscapes in the West are experiencing more frequent and intense fires due to hotter, drier summers. A recent study suggests that fire refugia – the green islands of live trees that remain after forest fires – can enhance forest regeneration. This research can guide us in deciding when the human intervention of tree planting is, and isn't, warranted – critical information in our warming world.
