  <dc:description>&lt;p&gt;&lt;span&gt;Population size of habitat-specialized butterflies is limited in part by host plant distribution and abundance. Effective conservation for host-specialist species requires knowledge of host-plant habitat conditions and relationships with the specialist species. Clayton’s copper butterfly (&lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;Lycaena dorcas claytoni&lt;/i&gt;&lt;span&gt;) is a Maine state-endangered species that relies exclusively on shrubby cinquefoil (&lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;Dasiphora fruticosa&lt;/i&gt;&lt;span&gt;) as its host. &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;Dasiphora fruticosa&lt;/i&gt;&lt;span&gt; occurs in 28 wetlands in Maine, ten of which are occupied by &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;L. d. claytoni.&lt;/i&gt;&lt;span&gt; Little is known about environmental conditions that support large, persistent stands of &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;D. fruticosa&lt;/i&gt;&lt;span&gt; in Maine. We evaluated the environment (hydrology, pore water and peat nutrients) associated with &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;D. fruticosa&lt;/i&gt;&lt;span&gt; distribution, age, and condition in Maine wetlands supporting robust stands of &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;D. fruticosa&lt;/i&gt;&lt;span&gt; to compare with &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;L. d. claytoni&lt;/i&gt;&lt;span&gt; occurrence. Although dominant water source in &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;D. fruticosa&lt;/i&gt;&lt;span&gt;—containing wetlands included both groundwater discharge and surface-flow, &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;D. fruticosa&lt;/i&gt;&lt;span&gt; coverage was greater in wetlands with consistent growing season water levels that dropped into or below the root zone by late season, and its distributions within wetlands reflected pore water hydrogen ion and conductivity gradients. Flooding magnitude and duration were greatest during the &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;L.d. claytoni&lt;/i&gt;&lt;span&gt; larval feeding period, whereas, mean depth to water table and upwelling increased and were most variable following the &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;L. d. claytoni&lt;/i&gt;&lt;span&gt; egg-laying period that precedes &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;D. fruticosa&lt;/i&gt;&lt;span&gt; senescence. Oldest sampled shrubs were 37&amp;nbsp;years, and older shrubs were larger and slower-growing. Encounter rates of &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;L. d. claytoni&lt;/i&gt;&lt;span&gt; were greater in wetlands with larger &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;D. fruticosa&lt;/i&gt;&lt;span&gt; plants of intermediate age and greater bloom density. Wetland management that combines conditions associated with &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;D. fruticosa&lt;/i&gt;&lt;span&gt; abundance (e.g., non-forested, seasonally consistent water levels with high conductivity) and &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;L. d. claytoni&lt;/i&gt;&lt;span&gt; occurrence (e.g., drawdown below the root zone following egg-laying, abundant blooms on intermediate-aged &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;D. fruticosa,&lt;/i&gt;&lt;span&gt; nearby &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;D. fruticosa&lt;/i&gt;&lt;span&gt;-containing wetlands) will aid &lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;L. d. claytoni&lt;/i&gt;&lt;span&gt; conservation.&lt;/span&gt;&lt;/p&gt;</dc:description>
