The adaptation of forest management to changing environmental conditions due climate change relies on information the current and tree vitality. In common practice, percentage crown defoliation is used as a proxy for vitality, an approach that has several drawbacks. By performing laser scanning plot in Hainich National Park, we tested new quantifying Based difference structural complexity measured between summer winter, assessed via box-dimension, provides objective reproducible method does...
Accurate detection and delineation of individual trees their crowns in dense forest environments are essential for management ecological applications. This study explores the potential combining leaf-off leaf-on structure from motion (SfM) data products unoccupied aerial vehicles (UAVs) equipped with RGB cameras. The main objective was to develop a reliable method precise tree stem crown deciduous forests, demonstrated at structurally diverse old-growth Hainich National Park, Germany. Stem...
Key message Analyzing fine branch length characteristics in beech trees using single-tree QSMs derived from laser scanning reveals insights into drought-induced changes vitality, which include shedding and reduced shoot growth. Abstract Climate change causes increasing temperatures precipitation anomalies, result deteriorations of tree health declines ecosystem services forests. It is therefore crucial to monitor vitality preserve forests their functions. However, methods describing situ are...
