Post-drought forest inventory and tree canopy health data, Rhӧn Biosphere Reserve, Germany, 2021

This dataset comprises forest inventory (diameter at breast height, tree height, social class and relative crown distance) and tree canopy health data (extent of overall damage, discolouration and defoliation) collected in 2021 from sites within core protected areas of the UNESCO Rhӧn Biosphere Reserve dominated by European beech (Fagus sylvatica) forest. The study forests were subject to the extreme drought event that impacted central Europe in 2018/2019 and this project sought to collect data to enable the analysis of individual tree and stand level characteristics that influence the response (canopy damage and defoliation) of European beech trees to extreme drought events. Field assessments of individual tree and stand canopy health were carried out within this project collecting data comprising canopy condition assessments and measurements of individual tree size and stand demography. The work was supported by the Natural Environment Research Council (Grant NE/V00929X/1).

本数据集收录了2021年采集自联合国教科文组织伦山生物圈保护区（UNESCO Rhön Biosphere Reserve）核心保护区域的森林清查（forest inventory）与林冠健康（tree canopy health）数据。其中森林清查数据包括胸径（diameter at breast height）、树高、林木社会地位（social class）与相对冠距（relative crown distance）；林冠健康数据涵盖整体受损程度、冠部变色程度与落叶程度。该保护区的优势植被为欧洲山毛榉（Fagus sylvatica）林。本研究样地内的森林曾遭受2018至2019年间影响中欧地区的极端干旱事件，本项目旨在通过采集数据，分析影响欧洲山毛榉对极端干旱事件响应（林冠受损与落叶情况）的单木与林分尺度特征。本项目通过开展单木及林分林冠健康状况的野外调查，采集了包含林冠状况评估、单木尺寸测量以及林分种群结构（stand demography）在内的相关数据。本研究由英国自然环境研究委员会（Natural Environment Research Council）资助，项目编号为NE/V00929X/1。
