  <dc:description>&lt;p&gt;&lt;span id="_mce_caret" data-mce-bogus="1" data-mce-type="format-caret"&gt;&lt;span&gt;Counts were made of pollen in traps formed by enclosed bark in two remnants of bristlecone pine,&amp;nbsp;&lt;/span&gt;&lt;i&gt;Pinus aristata&lt;/i&gt;&lt;span&gt;&amp;nbsp;Engelm., from the White Mountains of east-central California. The traps, dated by tree-rings at A.D. 350 and 1300 B.C., contained a major complex of pine-sagebrush pollen and traces of other species, representing the equivalent of the present vegetation.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;</dc:description>
