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

manifest in post-fire plant establishment and growth (A. C., Cilimburg, and

Short. K. C., 2005).
