slope length, slope gradient (steepness), and orientati<strong>on</strong> with respect to solar radiati<strong>on</strong> (aspect). Slope length,<br />

slope gradient, and positi<strong>on</strong> al<strong>on</strong>g the slope also influence soil stability and ecological sensitivity to disturbance<br />
