The objectives of this study were to develop estimates of smoke emissions from wild and prescribed fires in B.C. forests during 1981-90, and to compare these with amounts that occurred before European settlement. The prescribed fires included in this study were carried out under…

Atmospheric aerosol particles play a vital role in the Earth's radiative energy budget. They exert a net cooling influence on climate by directly reflecting the solar radiation to space and by modifying the shortwave reflective properties of clouds. Each year, increasing amounts…

The Atmospheric Boundary Layer (ABL) is the lowest portion of the Earth's atmosphere which is affected significantly by the properties of the Earth's (land or ocean) surface. The ABL may show a large daily variation in wind, temperature, and stability or turbulence. The ABL is…

Wildland fires produce smoke that contributes to reduced visibility over roadways with potentially tragic consequences. Land managers need to reduce this potential hazard. Two indices are described that correlate with conditions associated with roadway hazard. The Dispersion…

Residents of Canada and other northern circumpolar countries are concerned with the scenarios of climate change since Global Circulation Models predict that global warming over the next 30-50 years will be most evident in the northern regions (Bolin et at. 1986; Roots 1989;…

Studies on the radionuclear contamination of forests caused by the Chernobyl disaster of 1986 show that as of the year 1992, in the Bryansk Region, 84% of the radionuclides (averaged over all the forest types examined) have been concentrated in the forest fuels of soil cover and…

Tropical forest felling can be for the purpose of traditional shifting cultivation, after which forest is re-established, or for permanent land-use change, which is defined as deforestation. Recent decades have seen a dramatic increase in tropical deforestation caused by slash-…

Prescribed burning is an effective way of restoring the fire process to ponderosa pine (Pinus ponderosa Dougl. ex Laws.) ecosystems of the Southwest. If used judiciously, fire can provide valuable effects for hazard reduction, natural regeneration, thinning, vegetation…

Fires can produce a wide range of changes in nutrient cycles of forest, shrub, and grassland ecosystems depending on fire severity, fire frequency, vegetation, and climate. These changes can be beneficial when fires increase the availability of plant nutrients, and deleterious…

After nearly a century of avid fire suppression, land managers are substantially increasing prescribed burning to meet ecosystem management objectives. As scientists and managers we need to accurately quantify the capacity of airsheds to assimilate smoke and related atmospheric…
