  <dc:description>&lt;p&gt;&lt;span&gt;Loss of local biodiversity resulting from abrupt environmental change is a significant environmental problem throughout the world. Extinctions of plants are particularly important yet are often overlooked. Drawing from a case in Hawai‘i, a global hotspot for plant and other extinctions, we demonstrate an effort to better understand and determine priorities for the management of an endangered plant (‘Ihi makole or&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="italic"&gt;Portulaca sclerocarpa&lt;/span&gt;&lt;/i&gt;&lt;span&gt;) in the face of rapid and extreme environmental change. Volcanic heat emissions and biological invasions have anecdotally been suggested as possible threats to the species. We integrated&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="italic"&gt;P. sclerocarpa&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;outplanting with efforts to collect geological and ecological data to gauge the role of elevated soil temperatures and invasive grasses in driving&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="italic"&gt;P. sclerocarpa&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;mortality and population decline. We measured soil temperature, soil depth, surrounding cover and&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="italic"&gt;P. sclerocarpa&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;survivorship over three decades. The abundance of wild&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="italic"&gt;P. sclerocarpa&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;decreased by 99.7% from the 1990s to 2021. Only 51% of outplantings persisted through 3–4 years. Binomial regression and structural equation modelling revealed that, among the variables we analysed, high soil temperatures were most strongly associated with population decline. Finding the niche where soil temperatures are low enough to allow&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="italic"&gt;P. sclerocarpa&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;survival but high enough to limit other agents of&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span class="italic"&gt;P. sclerocarpa&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;mortality may be necessary to increase population growth of this species.&lt;/span&gt;&lt;/p&gt;</dc:description>
