The recruitment niche of mountain birch (<i>Betula pubescens</i> ssp. <i>tortuosa</i>) and implications for woodland restoration

These data were collected for and used in the research article titled "The recruitment niche of mountain birch (<i>Betula pubescens</i> ssp. <i>tortuosa</i>) and implications for woodland restoration".Authors: Guðrún Óskarsdóttir, Kristín Svavarsdóttir, James D. M. Speed, Thóra E. Thórhallsdóttir,.The data describes seed and seedling counts, the substrate type they were recorded in, and seedling survival from 2018 to 2020 for a sampled population of a mountain birch (<i>Betula pubescens</i> ssp. <i>tortuosa</i>) on Skeiðarársandur glacial outwash plain in southeast Iceland. All data were gathered from 2018 to 2020, but the intensity of sampling varies between years. See research article for details regarding study design, data collection, and analyses.本数据集为配合题为《山地桦树（*Betula pubescens* ssp. *tortuosa*）的生态位招募特征及其对林地修复的启示》的研究论文所采集并使用。作者包括：Guðrún Óskarsdóttir、Kristín Svavarsdóttir、James D. M. Speed、Thóra E. Thórhallsdóttir。本数据集记录了冰岛东南部斯凯达拉桑杜尔（Skeiðarársandur）冰水平原上的山地桦树（*Betula pubescens* ssp. *tortuosa*）采样种群在2018至2020年间的种子与幼苗数量、定植基质类型以及幼苗存活情况。所有数据的采集周期为2018年至2020年，但各年度的采样强度存在差异。有关研究设计、数据采集流程与分析方法的详细信息，请参阅该研究论文。
