<br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />Summary of Previous Studies <br /> <br /> <br />Effects of Fire on Soil <br /> <br />· For arid areas of the southwestern U.S., vegetative regrowth after <br />severe burning can be very slow. <br /> <br />· Coarse textured soils are more likely to become highly water <br />repellent than fine textured clay soils. <br /> <br />· Lodgepole and Ponderosa Pine forests have displayed high water <br />repellency after burning, <br /> <br />· Soil formed from granitic parent material are sensitive to erosion. <br />The erosion rate is a function of the burn intensity. <br /> <br />Effects of Fire on Hydrology <br /> <br />· For a burned watershed, peak stream flows reported to be 2 to 60 <br />times greater than normal after a heavy rain. <br />
