During a forest fire approximately 8-10% of the heat generated is radiated
downward to the forest floor (A. C., Cilimburg, and Short. K. C., 2005).
Extensive soil heating takes time and is most likely to occur beneath heavy
fuels, like large-diameter tree stumps and logs, which can smolder for days orweeks. In general, an enduring, low-intensity fire in logging slash will have
more severe effects on forest soil than a fire that burns more intensely but
rapidlythrough tree crowns (A. C., Cilimburg, and Short. K. C., 2005).
Recovery to pre-fire conditions may take only as long as necessary for soil
biota to reestablish and surface organic matter to reaccumulate. In the
meantime, the physical, chemical, and biological changes in forest soil will be
