We suggest creating<br />
landscape heterogeneity<br />
in the Sierra<br />
Nevada by mimicking<br />
the <strong>for</strong>est conditions<br />

We suggest creating landscape heterogeneity in the Sierra Nevada by mimicking<br />
the <strong>for</strong>est conditions that would be created by the fire behavior and return<br />
interval associated with differences in slope position, aspect, and slope steepness<br />
(Sherlock 2007). In general, stem density and canopy cover would be highest in<br />
drainages and riparian areas, and then decrease over the midslope and become lowest<br />
near and on ridgetops (fig. 10). Stem density and canopy cover in all three areas<br />
would be higher on northeast aspects compared to southwest. Stand density would<br />
also vary with slope becoming more open as slopes steepen.<br />
