A total of nine &lt;em&gt;Phytophthora&lt;/em&gt; species, including &lt;em&gt;P. alticola&lt;/em&gt;, &lt;em&gt;P. multivora&lt;/em&gt;, &lt;em&gt;P. litoralis&lt;/em&gt;, &lt;em&gt;P. inundata&lt;/em&gt;, &lt;em&gt;P. nicotianae&lt;/em&gt; and &lt;em&gt;P. palmivora&lt;/em&gt; were isolated. In addition, three previously undescribed species, &lt;em&gt;Phytophthora&lt;/em&gt; aff. &lt;em&gt;arenaria&lt;/em&gt;, &lt;em&gt;Phytophthora&lt;/em&gt; aff. &lt;em&gt;humicola&lt;/em&gt; and &lt;em&gt;Phytophthora&lt;/em&gt; sp. &lt;em&gt;ohioensis&lt;/em&gt; were isolated. Isolates were recovered from a wide range of native and non-native host genera, including &lt;em&gt;Agonis&lt;/em&gt;, &lt;em&gt;Allocasuarina&lt;/em&gt;, &lt;em&gt;Brachychiton&lt;/em&gt;, &lt;em&gt;Calothamnus&lt;/em&gt;, &lt;em&gt;Casuarina&lt;/em&gt;, &lt;em&gt;Corymbia&lt;/em&gt;, &lt;em&gt;Dracaena&lt;/em&gt;, &lt;em&gt;Eucalyptus&lt;/em&gt;, &lt;em&gt;Ficus&lt;/em&gt;, &lt;em&gt;Pyrus and Xanthorrhoea&lt;/em&gt;. &lt;em&gt;Phytophthora multivora&lt;/em&gt; was the most commonly isolated species. Out of 230 samples collected 69 were found to be infected with &lt;em&gt;Phytophthora.&lt;/em&gt; Of those 69, 54% were located within parks and gardens, 36% within remnant bushland, and 10% within streetscapes. These pathogens may play a key role in the premature decline in health of the urban forest throughout Perth, and should be managed according to the precautionary principle and given high priority when considering future sustainable management strategies.&lt;/p&gt;</style></abstract></record></records></xml>
