An inventory of particulate matter and air toxic emissions from prescribed fires in the USA for 1989
This report documents a prescribed fire emissions inventory developed using consistent methodology for each of the 50 states of the USA for calendar year 1989. Emissions of particulate matter, selected toxic compounds, and a few other carbon-containing compounds are estimated.…

We present evidence that fire suppression may have contributed to the fungal decline of torreya (Torreya taxifolia). During the 1950's torreya suffered a catastrophic die-back. The torreya die-back was probably caused by needle pathogens induced through environmental stress.…

We develop a simple analytical model to estimate the thickness of a smoke layer formed by a plume of a large area fire and to account for crosswinds. We take advantage of the dominant flow features in the upper part of the rising plume and in the smoke layer far from the plume…
