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.…
