Evidence for environmentally enhanced forest growth. [PDF]

Proc Natl Acad Sci U S A, 2014
SignificanceNorthern forests have sequestered a substantial amount of carbon dioxide from the atmosphere during the past several decades. This large carbon (C) sink usually is considered to be driven by tree regrowth after stand-replacing disturbance and growth enhancement due to environmental changes, but the relative contribution between these two ...

Forest structure, stand composition, and climate-growth response in montane forests of Jiuzhaigou National Nature Reserve, China. [PDF]

, 2013
Montane forests of western China provide an opportunity to establish baseline studies for climate change. The region is being impacted by climate change, air pollution, and significant human impacts from tourism.

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

Frontiers 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 ...

Old-growth forest carbon sinks overestimated [PDF]

Nature, 2021
Luyssaert et al.1 reported that unmanaged, old-growth forests continue to sequester atmospheric carbon (C) at a rate of 2.4 ± 0.8 Mg C ha–1 yr–1 for stand ages exceeding 200 years. This claim was based on an analysis of net ecosystem productivity (NEP) and other C flux data from temperate or boreal forest plots compiled from published studies and ...

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

Annals 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

Frontiers 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

Remote 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

Frontiers 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

Remote 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.

Spatiotemporal changes in biomass after selective logging in a lowland tropical rainforest in peninsular Malaysia [PDF]

, 2021
We studied biomass changes in a lowland tropical rain forest in the Pasoh Forest Reserve of Peninsular Malaysia after selective logging in 1958. A tree census was undertaken every 2 years from 1998 to 2012 in a 6-ha logged forest plot.
