A fire growth model, FARSITE (Fire ARea SImulator) is under development for simulating the spread and behavior of prescribed natural fires. The models uses a technique for wave propagation to expand surface fire fronts in 2 dimensions. Points defining...

We develop a simple analytical model to estimate the thickness of a smoke layer formed by a plume of a large area fire and to account for crosswinds. We take advantage of the dominant flow features in the upper part of the rising plume and in the smoke...

Changing climate and land use appear to importantly affect the biosphere by way of impacts on fire regimes. Feedback effects on climate and air quality are likely through emissions of trace gases, aerosols, and particulates that affect radiation...

Mechanized full-tree logging is the preferred harvesting system in Northeastern Ontario. These operations typically involve roadside delimbing, producing large quantities of slash at roadsides and landings. Slash pile burning involves gathering the...

Recreation is of increasing importance in forest environments. Fire has both short-term effects, trail closures, smoke impacts; and long-term effects, residual 'scars,' potential hazards, on forest recreation. The general public is gaining...

Traditionally, in the Southwest, ponderosa pine (Pinus ponderosa) red slash has not been treated with fire to meet resource objectives until all slash has fully cured, usually a 2-to-4-year wait. Waiting for slash to cure is still the widespread...
