欧洲赤松（Pinus sylvestris L.）是苏格兰高地森林的基础物种和国家标志。由于大量开采，目前的原生松木覆盖率仅占冰后期最大值的一小部分。为了扭转这种下降趋势，已经启动了各种计划，以促进种植新的松树和扩大旧的松树。这包括指定种子区，以控制剩余的遗传资源。分区主要是基于松树之间的生化相似性，但根据定义，中性分子标记不反映当地的表型适应。苏格兰境内的环境变化很大，目前尚不清楚这在多大程度上形成了苏格兰人口之间的适应性分化模式。系统的，范围广泛的共同环境试验可以提供洞察到原生松树的进化，表明环境如何影响表型变异和如何保持变异。精心设计的实验还可以通过分子标记分析提供有关种群历史和种群间联系的数据。总之，这些试验的表型和分子数据集可以提供一个强大的基础，完善种子转移指南苏格兰苏格兰松在苏格兰，并应形成保护行动的科学基础上，这个国家重要的栖息地。
Scots pine (Pinus sylvestris L.) is a foundation species in Scottish highland forests and a national icon. Due to heavy exploitation, the current native pinewood coverage represents a small fraction of the postglacial maximum. To reverse this decline, various schemes have been initiated to promote planting of new and expansion of old pinewoods. This includes the designation of seed zones for control of the remaining genetic resources. The zoning was based mainly on biochemical similarity among pinewoods but, by definition, neutral molecular markers do not reflect local phenotypic adaptation. Environmental variation within Scotland is substantial and it is not yet clear to what extent this has shaped patterns of adaptive differentiation among Scottish populations. Systematic, range-wide common environment trials can provide insights into the evolution of the native pinewoods, indicating how environment has influenced phenotypic variation and how variation is maintained. Careful design of such experiments can also provide data on the history and connectivity among populations, by molecular marker analysis. Together, phenotypic and molecular datasets from such trials can provide a robust basis for refining seed transfer guidelines for Scots pine in Scotland and should form the scientific basis for conservation action on this nationally important habitat.
