The impact of anticipated global change on growth and productivity of Norway spruce and European beech is still discussed controversially. The analysis of inter- and intra-annual growth dynamics in different environmental conditions will provide detailed insight into the resilience and adaption potential of stem radial growth to climatic extreme events and environmental changes.This study will be based on the exploitation of already existing unique long dendrometer time series collected at three dendroecological field sites of the Institute for Forest Growth along an altitudinal gradient in south-western Germany. At the three field sites, stem radial displacement of beech and spruce sample trees has been recorded by automatic precision point dendrometers in high temporal resolution (every 15 minutes) since 1990 at an altitude of 1250 m and since 1997 in addition at 450 m and 750 m. At these sites meteorological and pedological parameters have been measured during this observation period. Complementary environmental data, including high resolution time series of tropospheric CO2 concentration measurements from the nearby environmental monitoring station "Schauinsland" of the German Federal Environmental Agency (Umweltbundesamt) will be available. For extension of the retrospective analyses, stem discs and increment cores of dendrometer trees and neighboring trees will be sampled at each of the three sites.The innovative approach of combining long-term dendrometer data with tree ring features such as ring width, cell structure, intra-annual density profiles and data from detailed studies on cambial activity and wood formation, provides a great opportunity to deepen our understanding and knowledge about the interactions of different environmental factors with the short-, medium- and long-term growth dynamics of the two important tree species in German forestry.

预计全球变化对挪威云杉和欧洲山毛榉的增长和生产率的影响仍在有争议上讨论。 The analysis of inter- and intra-annual growth dynamics in different environmental conditions will provide detailed insight into the resilience and adaption potential of stem radial growth to climatic extreme events and environmental changes.This study will be based on the exploitation of already existing unique long dendrometer time series collected at three dendroecological field sites of the Institute for Forest Growth along an altitudinal gradient in south-western Germany.在三个野外地点，自1990年以来，自1990年以来的高度分辨率（每15分钟）以1250 m的高度和自1997年以来，在450 m和750 m以来，已经记录了山毛榉和云杉样品树的茎径向位移。在这些地点，在此观察期已经测量了气象和教学参数。互补的环境数据，包括来自德国联邦环境局（Umweltbundesamt）附近环境监测站“ Schauinsland”的对流层CO2浓度测量的高分辨率时间序列。为了扩展回顾性分析，将在三个站点的每个站点中的每个站点中进行采样，将茎盘和树木圆盘和相邻树的增量芯进行采样。将长期树枝状电表数据与树环的特征相结合的创新方法，例如环形宽度，电池结构，细胞结构，幼体密度概况和与知识相互作用的详细范围的研究，以深入研究cambial Active and Inrountion，以深入研究cambial Active and Inrountion，以深入研究cambial Active and Internotive of Cambial Active，以加强木环的研究，以加强木单的范围。德国林业中两个重要树种的短期，中，长期生长动力学。
