A new approach for modeling stand height development of German forests under climate change

open access: yesFrontiers in Forests and Global Change, 2023
IntroductionWe developed a new approach for site index curve models that combines longitudinal height development patterns derived from state-space data with the broad environmental conditions covered by space-for-time data.MethodsFor this, we gathered ...

Allometric models for above-ground biomass, carbon and nutrient content of wild cherry (Prunus avium L.) trees in agroforestry systems

open access: yesAnnals of Forest Science, 2023
Key message We provide a set of allometric models for wild cherry trees (Prunus avium L.) established in agroforestry systems. A total of 70 trees in southwestern Germany were surveyed using terrestrial laser scanning and analysed using quantitative ...

Multivariate drought stress response of Norway spruce, silver fir and Douglas fir along elevational gradients in Southwestern Germany

open access: yesFrontiers in Ecology and Evolution, 2022
The conifer tree species Norway spruce (Picea abies), silver fir (Abies alba) and Douglas fir (Pseudotsuga menziesii) are important elements in tree species composition and forest management of Central European forests, but their potential to thrive ...

Modelling and Comparing Shading Effects of 3D Tree Structures with Virtual Leaves

open access: yesRemote Sensing, 2021
Reduced solar radiation brought about by trees on agricultural land can both positively and negatively affect crop growth. For a better understanding of this issue, we aim for an improved simulation of the shade cast by trees in agroforestry systems and ...

High Phenotypic Plasticity, but Low Signals of Local Adaptation to Climate in a Large-Scale Transplant Experiment of Picea abies (L.) Karst. in Europe

open access: yesFrontiers in Forests and Global Change, 2022
The most common tool to predict future changes in species range are species distribution models. These models do, however, often underestimate potential future habitat, as they do not account for phenotypic plasticity and local adaptation, although being

Measurement of Forest Inventory Parameters with Apple iPad Pro and Integrated LiDAR Technology

open access: yesRemote Sensing, 2021
The estimation of single tree and complete stand information is one of the central tasks of forest inventory. In recent years, automatic algorithms have been successfully developed for the detection and measurement of trees with laser scanning technology.

Charcoal kiln sites, associated landscape attributes and historic forest conditions: DTM-based investigations in Hesse (Germany)

open access: yesForest Ecosystems, 2016
Background An examination of the distribution of ancient charcoal kiln sites in the forest landscape seems to be worthwhile, since general trends in the selection of suitable kiln site locations in the past might become obvious.

Success factors for high-quality oak forest (Quercus robur, Q. petraea) regeneration

open access: yesForest Ecosystems, 2019
Background Within the framework of close-to-nature forestry, oak forest (Quercus robur, Q. petraea) regeneration techniques that consider both silvicultural and nature conservation demands have become a very important issue.

Cooperative root graft networks benefit mangrove trees under stress

open access: yesCommunications Biology, 2021
Vovides et al. investigate mangrove trees at a field site in the Gulf of Mexico to determine the effect of stress on root networks. Non-destructive analyses indicate that the probability of non-selective cooperative root grafting increases with higher ...

Quantifying the effect of persistent dryer climates on forest productivity and implications for forest planning: a case study in northern Germany

open access: yesForest Ecosystems, 2018
Background Forest management decisions are based on expectations of future developments. For sound decisions it is essential to accurately predict the expected values in future developments and to account for their inherent uncertainty, for example the ...
