Forests dominated by European beech (Fagus sylvatica L.) are among both the most widespread in Europe and the most intensely exploited globally. One of the largest remnants of unmanaged beech forests in Europe is the Uholka-Shyrokyi Luh forest in Transcarpathia, Ukraine, covering 8,800 ha of primeval forest. In 2000, a permanent forest plot of 10 ha has been established in the Uholka massif. All living and dead trees with a diameter at breast height (DBH) ≥ 60 mm were identified to species, DBH measured, stems tagged and mapped. Since then, the plot has been remeasured in 2005, 2010, and 2015. In total, 4,820 individual trees were measured with 14,116 individual measurements throughout all four inventories. In spring 2018, an Airborne Laser Scan was carried out, covering the Uholka-Shyrokyi Luh forest. This data set allows us to derive a high-resolution digital elevation model (DEM) of the plot area. European beech covers a share of ≈ 95% of the basal area (BA) of all living stems. While BA was relatively stable throughout all inventories (≈ 38 m /ha), the number of stems increased considerably between 2010 and 2015 from 290 to 430 stems/ha. Additionally, the proportion of beech stems decreased from 95% in 2010 to 86% in 2015. The continuity of the share of beech on BA and the decrease in number of stems can be traced back to disturbance events, which led to an increase of more light demanding species in the recruitment but did not alter the distribution of BA as these small trees contribute very little to BA. The data set allows for important insights into the development and the spatial and temporal dynamics of primeval beech forests. It can be used to quantify the demographic processes growth, mortality, and recruitment, and to study inter- and intraspecific effects on demographic rates, stand structure, and species composition.

以欧洲山毛榉（Fagus sylvatica L.）为主的森林既是欧洲分布最广的森林之一，也是全球开发强度最大的森林之一。欧洲最大的未受管理的山毛榉森林遗迹之一是乌克兰外喀尔巴阡地区的乌霍尔卡-希罗基卢赫森林，占地8800公顷的原始森林。2000年，在乌霍尔卡地块建立了一个10公顷的永久性森林样地。所有胸径（DBH）≥60毫米的活树和死树都进行了树种鉴定、测量胸径、标记树干并绘制地图。从那时起，该样地在2005年、2010年和2015年进行了重新测量。在所有四次清查中，总共测量了4820棵单株树木，进行了14116次单株测量。2018年春季，对乌霍尔卡-希罗基卢赫森林进行了机载激光扫描。该数据集使我们能够得出样地面积的高分辨率数字高程模型（DEM）。欧洲山毛榉在所有活立木的断面积（BA）中占比约95%。虽然在所有清查中BA相对稳定（约38平方米/公顷），但2010年至2015年间，每公顷的树木数量从290棵大幅增加到430棵。此外，山毛榉树干的比例从2010年的95%下降到2015年的86%。山毛榉在BA中所占比例的连续性以及树干数量的减少可追溯到干扰事件，这些事件导致在更新过程中对光照要求更高的物种增加，但并未改变BA的分布，因为这些小树对BA的贡献非常小。该数据集有助于深入了解原始山毛榉森林的发展以及空间和时间动态。它可用于量化种群统计学过程（生长、死亡和更新），并研究种间和种内对种群统计学速率、林分结构和物种组成的影响。除了引用本数据论文外，使用该数据集不存在版权或专有限制。
