  <dc:description>&lt;p&gt;&lt;span&gt;(1) The effects of substrate disturbance on perennial plant succession in the Mojave Desert were assessed at three military camps abandoned for 40 years. &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span&gt;(2) Soil compaction, removal of the top layer of soil, and alteration of drainage channel density caused significant changes in perennial plant cover, density, and relative species composition. &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span&gt;(3) Long-lived species, predominantly &lt;i&gt;Larrea tridentata&lt;/i&gt;, were dominant in all control areas but percentage cover and density were greatly reduced in areas where substrate alterations were significant. &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span&gt;(4) Pioneer species such as &lt;i&gt;Ambrosia dumosa&lt;/i&gt; and &lt;i&gt;Hymenoclea salsola&lt;/i&gt; had percentage cover values similar to or greater than controls in most areas where substrate alterations were significant, and these species were dominant in the majority of disturbed areas. &lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span&gt;(5) Where substrate alterations were insignificant in disturbed areas at one camp, &lt;i&gt;Larrea&lt;/i&gt; was the dominant species as in the control.&lt;/span&gt;&lt;/p&gt;</dc:description>
