Surveys demonstrated the presence of four species of &lt;em&gt;Phytophthora&lt;/em&gt; including one novel species. By far, the most common species was &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt;; &lt;em&gt;P.&amp;nbsp;citricola&lt;/em&gt; and &lt;em&gt;P.&amp;nbsp;cambivora&lt;/em&gt; were isolated infrequently. In few instances, &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt; was isolated from fine roots and necroses on larger roots. No special pattern of incidence was found, but &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt; was more commonly isolated from greater Integrated Moisture Index values suggesting moist lower bottomlands favour this &lt;em&gt;Phytophthora&lt;/em&gt; species. When tree crown condition was examined relative to the presence of &lt;em&gt;Phytophthora&lt;/em&gt;, no significant association was found. However, roots of declining &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt;-infested trees had 2.5 times less fine roots than non-infested and healthy trees, which was significantly different. The population densities of &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt; from declining trees were significantly greater than from healthy trees, suggesting increased pathogen activity that has the potential to cause dieback and decline and possibly the cause of a reduced fine root amount found on declining trees.&lt;/p&gt;</style></abstract></record></records></xml>
