  <dc:description>&lt;p&gt;&lt;span&gt;Element-concentration baselines are given for&amp;nbsp;&lt;/span&gt;&lt;i&gt;Parmelia sulcata&lt;/i&gt;&lt;span&gt;&amp;nbsp;and associated soils.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Parmelia chlorochroa&lt;/i&gt;&lt;span&gt;&amp;nbsp;was found sporadically and therefore only representative concentration ranges are reported for this species. Element data include (1) for lichens; Al, As, Ba, B, Ca, Cr, Cu, Fe, Hg, Mn, Ni, P, Sr, S, Ti, V, Y, and Zn; and (2) for soils: Al, Ba, Be, Ca, Cs, Cr, Cu, Fe, Hg, Mg, Mn, Ni, Nb, P, Pb, Sr, S, Ti, V, Y, and Zn. Very little (usually &amp;lt; 10 %) of the variability in the element data for lichen material occurs regionally (&amp;gt; 7.2 km); thus,&amp;nbsp;&lt;/span&gt;&lt;i&gt;P sukata&lt;/i&gt;&lt;span&gt;&amp;nbsp;is, in general, chemically similar throughout the park. This same uniformity was found for soil geochemistry. Numerous samples collected at close intervals would be required, therefore, to produce detailed element-concentration maps for&amp;nbsp;&lt;/span&gt;&lt;i&gt;P. sulcata&lt;/i&gt;&lt;span&gt;&amp;nbsp;and soils. No instances of elemental phytotoxic conditions were found; however,&amp;nbsp;&lt;/span&gt;&lt;i&gt;P. sulcata&lt;/i&gt;&lt;span&gt;&amp;nbsp;apparently possesses large concentrations of Ba, Cu, Fe, Pb, S, V, and possibly Zn.&lt;/span&gt;&lt;/p&gt;</dc:description>
