Wildland fires have an irreplaceable role in sustaining many of our forests, shrublands and grasslands. They can be used as controlled burns or occur as free-burning wildfires, but can also be dangerous and destructive to fauna, human communities and natural resources. Through scientific understanding of their behavior, we can develop the tools to reliably use and manage fires across landscapes in ways that are compatible with the constraints of modern society while benefiting the ecosystems.u003cbru003e u003cbru003e The science of wildland fire is incomplete, however. Even the simplest fire behaviors - how fast they spread, how long they burn and how large they get - arise from a dynamical system of physical processes interacting in unexplored ways with heterogeneous biological, ecological and meteorological factors across many scales of time and space. The physics of heat transfer, combustion and ignition, for example, operate in all fires at millimeter and millisecond scales but wildfires can become conflagrations that burn for months and exceed millions of hectares....
