Branches, tops and other woody material left after pruning and thinning operations can safely be burnt under the standing trees. Provided the soil and lower humus layer are thoroughly moist and the correct procedure is followed there should not be any damage to trees which have…

Timberland owners and managers of southern forests are faced with a serious fuel buildup situation. The same favorable climate that promotes some of the fastest growing trees in the nation also produces large amounts of hazardous forest fuels. Wildfires are a constant threat…

Forest managers are seeking ways to manage smoke from their prescribed burns. Why? How much management is needed for an intermittent source of emissions occurring only once every three to five years? Isn't wood smoke good smoke? These and other questions must be faced.

This paper describes simple laboratory experiments to determine whether it is possible, or likely, that selenium is lost during burning operations in eucalypt forests. It appears that, after a fire, less than half of the selenium in forest litter may be left as residue in 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…
