Slash burning is an integral tool of forest management in the Pacific Northwest. The purpose of this study was to determine if mass- ignited, high intensity fires had less fuel consumption than moderate intensity fires. There was 23 percent less woody fuel consumption in high…

When prescribed burning is conducted at the wildland-urban interface (WUI), the smoke that is produced can sometimes inconvenience people, but it can also cause more serious health and safety problems. The public is unlikely to continue to tolerate the use of prescribed fire,…

Due to a rapidly expanding human population in Florida, fire management has become hampered by urban encroachment, smoke management issues, and forest fragmentation. For these and other reasons, fire has been excluded from many stands, resulting in the buildup of dangerous fuel…
