Seeds of Audouinia capitata, a threatened fynbos species, are known to germinate under natural conditions only after fires. Experimental results are presented which demonstrate that seed germination is initiated by chemical factor(s) found in smoke, derived from burning fynbos…

Fire is becoming recognized as a major issue throughout the North American continent. The last several years have seen major fire seasons in the United States, Canada, and Mexico. There are five areas where an international approach to fire management will be useful. Technology…

Biomass and hydrocarbon fuel fires are two common sources of obscuring smoke which present significant operational challenges over a broad range of possible viewing wavelengths. This is especially true of very large fires where the primary smoke particles (approx. 0.1-0.3 um…

BIOMASS burning is a primary source of many trace substances that are important in atmospheric chemistry. More than 80% of the world's biomass burning takes place in the tropics as a result of savanna fires, forest-clearing activity, and the burning of agricultural waste and…

The Ontario Ministry of Environment (MOE) recently participated in a joint Canadian/U.S. program to monitor the behavior and environmental impact of prescribed fires. Air, soil and ash samples were collected at the burn sites and analyzed for chlorinated dibenzo-p-dioxins (CDD)…

A detailed set of data was compiled on 20 large fire whirlwinds observed at 27 prescribed burns conducted in Ontario. There appear to be two types of such whirlwinds: one occurs in pairs on the leeward side of the convection column and the other is created after the entire…

Airborne measurements of 13 trace gases from seven forest fires in North America are used to determine their average emission factors. The emission factors are then used to estimate the contributions of biomass ubrning to the worldwide fluxes of these gases. The estimate for NH3…
