在重新造林计划中选择耐旱的植被可能有助于森林适应气候变化。为了为此类重新造林策略提供信息，我们测试了黑松 (Pinus contortaDoug. ex Loud. varlatifoliaEnglm.) 种群对干旱的反应，并推断从干燥的南部环境向北转移种子的潜在好处。该目标是通过将树木生态生长分析与长期遗传现场试验相结合来实现的。在不列颠哥伦比亚省南部的三个实验地点，对来自北美西部 23 个种群的 500 多棵树木进行了破坏性采样，代表了气候变暖的情况。远距离向南或向北迁移的种源32年后的增长明显低于当地人口的增长。所有种群均受到 2002 年严重自然干旱事件的影响。来自最南部地区的种源表现出最高的耐旱性，但生产力较低。当地品种多产且耐旱。与所有其他来源相比，北方北部的物种在南部测试地点显示出较低的生产力和耐旱性，这意味着对干旱的适应不良可能会阻止北方种群在预计的气候变化下充分利用更有利的生长条件。
Choosing drought‐tolerant planting stock in reforestation programs may help adapt forests to climate change. To inform such reforestation strategies, we test lodgepole pine (Pinus contortaDoug. ex Loud. varlatifoliaEnglm.) population response to drought and infer potential benefits of a northward transfer of seeds from drier, southern environments. The objective is addressed by combining dendroecological growth analysis with long‐term genetic field trials. Over 500 trees originating from 23 populations across western North America were destructively sampled in three experimental sites in southern British Columbia, representing a climate warming scenario. Growth after 32 years from provenances transferred southward or northward over long distances was significantly lower than growth of local populations. All populations were affected by a severe natural drought event in 2002. The provenances from the most southern locations showed the highest drought tolerance but low productivity. Local provenances were productive and drought tolerant. Provenances from the boreal north showed lower productivity and less drought tolerance on southern test sites than all other sources, implying that maladaptation to drought may prevent boreal populations from taking full advantage of more favorable growing conditions under projected climate change.
