Recent changes in air quality regulations present a potential obstacle to continued use of prescribed fire as a land management tool. Lowering of the acceptable daily concentration of particulate matter from 65 to 35 μg/m3 will bring much closer scrutiny of prescribed burning…

Vegetation fires produce biomass combustion residues, with color varying from dark black char to white mineral ash. The color-lightness of char and ash combustion residues is a qualitative parameter describing the post-fire condition of burned areas, and has been correlated with…

To help reduce the chance for high-severity fires in the western United States, thinning of the forest understory, midstory and overstory has become a necessity. In some cases, the resulting surface fuels are piled by hand and burned. As this two-part treatment method becomes…
