Observation shows that three types of horizontal vortices may form during intense wildland fires. Two of these vortices are longitudinal relative to the ambient wind and the third is transverse. One of the longitudinal types, a vortex pair, occurs with extreme heat and low to…

Fire is a natural phenomenon in Madrean Province ecosystems. Suppression of natural fire has altered ecosystem processes, however. Recognition of these alterations has led to the adoption of let-burn policies by many management agencies, but a let-burn policy has become less…

From the text...'When managing longleaf pine ecosystems it is not a question of whether or not to use fire, but rather what frequency, season and intensity is needed to achieve specific objectives. Longleaf ecosystems evolved under a chronic fire regime and thus the continual…

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…
