The combustion products (smoke) from forest wildfires or prescribed burns are often considered on a par with any other emission that might affect air quality. But enough is known about smoke from woody fuels to indicate that its importance is limited almost entirely to…

The benefits from fire use - including hazard reduction, silvicultural manipulation, pathogen control, and nutrient recycling - might be forfeited by public reaction to smoke, whether harmful or not. Generally, the public desires alternatives to burning, but might accept fire if…

Spontaneous combustion is thought to be a cause of many of the fires which occur in areas such as peat bogs or dry snags. The theories of spontaneous heating are presented, along with a discussion of possible ignition mechanisms in both wood-chip and hay fires. The physical…
