The post-harvest burning of agricultural fields is commonly used to dispose of crop residue and provide other desired services such as pest control. Despite careful regulation of burning, smoke plumes from field burning in the Pacific Northwest commonly degrade air quality,…

Much of the public's attitude toward wildland fire as an important part of natural processes has been misguided, sometimes through programs perpetuating fear and misunderstanding of the vital role of fire in wildlands. Results presented here were part of a larger study that…
