  <dc:description>&lt;p&gt;&lt;i&gt;Alnus viridis&lt;/i&gt;&lt;span&gt; seedlings were planted on placer mine spoil in an Alaskan subalpine watershed to bypass a seedling establishment bottleneck for &lt;/span&gt;&lt;i&gt;A. viridis,&lt;/i&gt;&lt;span&gt; and to evaluate the interaction between &lt;/span&gt;&lt;i&gt;A. viridis&lt;/i&gt;&lt;span&gt; and the dominant riparian woody plants,&lt;/span&gt;&lt;i&gt; Salix alaxensis&lt;/i&gt;&lt;span&gt; and &lt;/span&gt;&lt;i&gt;Populus balsamifera&lt;/i&gt;&lt;span&gt;. The study area was divided into 11 replicate blocks, each on a homogeneous recontoured spoil pile. Blocks were divided into two 0.01 ha plots, and treatments without (control) and with 84 planted &lt;/span&gt;&lt;i&gt;A. viridis&lt;/i&gt;&lt;span&gt; seedlings were randomly assigned to plots. After 10 years, the &lt;/span&gt;&lt;i&gt;Alnus&lt;/i&gt;&lt;span&gt; treatment had a dense stand of &lt;/span&gt;&lt;i&gt;A. viridis&lt;/i&gt;&lt;span&gt; 1–2 m tall, while the control had fewer, smaller seedlings. Compared to the control, planted &lt;/span&gt;&lt;i&gt;A. viridis&lt;/i&gt;&lt;span&gt; had a neutral effect on &lt;/span&gt;&lt;i&gt;S. alaxensis&lt;/i&gt;&lt;span&gt; and inhibited &lt;/span&gt;&lt;i&gt;P. balsamifera&lt;/i&gt;&lt;span&gt; at the seedling establishment stage, but facilitated the growth of established plants of both species, with many plants overtopping the &lt;/span&gt;&lt;i&gt;A. viridis&lt;/i&gt;&lt;span&gt; canopy. Compared to the control, &lt;/span&gt;&lt;i&gt;S. alaxensis&lt;/i&gt;&lt;span&gt; plants in the &lt;/span&gt;&lt;i&gt;Alnus&lt;/i&gt;&lt;span&gt; treatment had higher levels of foliar N and δ15N values closer to those of &lt;/span&gt;&lt;i&gt;A. viridis&lt;/i&gt;&lt;span&gt;, indicating the importance of N fixation by &lt;/span&gt;&lt;i&gt;A. viridis&lt;/i&gt;&lt;span&gt;. Planting &lt;/span&gt;&lt;i&gt;A. viridis&lt;/i&gt;&lt;span&gt; accelerated the rate of succession by stimulating growth of woody dominants.&lt;/span&gt;&lt;/p&gt;</dc:description>
