As early as 1890, thoughtful persons had observed and pointed out that controlled fire might have a place and was possibly necessary in the silviculture of longleaf pine. Dr. Roland Harper, a botonist, proposed its use for understory hardwood control from 1911 to urge the use of…

In Mediterranean climates, the shrubby plant cover and the coniferous forest above it are vulnerable to frequent large fires. The fuelbreak, a strip of land in a strategic area-such as a ridgetop-where fuel modification and often type conversion can be accomplished, is an…

A program of field and laboratory measurements of emissions from the burning of agricultural residues (primarily cereal straw and stubble) and plume behavior is described. Relationships investigated include the dependence of total emissions and plume concentrations on fuel…

During the autumn of 1975, the Iowa Department of Environmental Quality conducted a study to determine the impact of the open burning of leaves on local are quality in the Des Moines (Iowa) metropolitan area. The results of the study show that open burning can cause excesses of…

Present knowledge indicates that prescribed forest and agricultural burning can be continued with minimal adverse affects. The most serious objection to burning is the limited visibility that may persist temporarily in the vicinity of the fire. Smoke can be a severe problem near…

The Task Force on Prescribed Burning was established in the spring of 1975 to inform and guide the Council on the appropriate use of fire in forest management. The Task Force accordingly synthesized knowledge about fire in forest ecosystems, its effects on air and water, and its…

Twenty control burns performed with a wide range of fuel loadings and moisture conditions were used to study the effectiveness of old fuel reduction under standing Douglas-fir/larch forest. This paper reports the influence of burning on nutrient retention and loss from the soil…

Wood versus fossil fuel as a source of excess carbon dioxide in the atmosphere: a preliminary report
If the amounts of wood consumed in deforestation to increase agricultural land and as firewood in underindustrialized countries are added to the amount consumed by the money economics as forest products, the estimates of the net amount of wood removed from the biosphere in this…
