The frequency of forest fires during the past 600 yr was studied on 281 sample plots within boreal forest ecosystems in a river valley in northern Sweden. Fire scars in living and dead trees were used for dating past fires. Before fire suppression started in the 19th century the…

Plume trajectory measurements were made at a power station on the South African Highveld under mainly near-neutral stability conditions. The maximum distance of observation ranged from 1050 to 6750 m. The fit of the models of Briggs (1969, 1970) and of Moore (1973, 1974) to the…

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…

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…
