Local and landscape-scale agricultural intensification is a major driver of global biodiversity loss. Controversially discussed solutions include wildlife-friendly farming or combining high-intensity with land-sparing for nature. Here, we integrate crop productivity data smallholder cacao in Indonesia to exemplify tropical agroforests that there little relationship between yield under current management, opening substantial opportunities management. Species richness trees, fungi,...
Abstract The complexity of forest structures plays a crucial role in regulating ecosystem functions and strongly influences biodiversity. Yet, knowledge the global patterns determinants structural remains scarce. Using stand index based on terrestrial laser scanning, we quantify boreal, temperate, subtropical tropical primary forests. We find that variation is largely explained by annual precipitation seasonality (R² = 0.89). forests as benchmark, model potential across biomes present map...
At least 10 different methods to determine exposure for hemispherical photographs were used by scientists in the last two decades, severely hampering comparability among studies. Here, an overview of applied is reported. For standardization photographic exposure, a time-consuming reference measurement open land towards unobstructed sky was required so far. The Histogram Methods proposed here make use technical advances digital cameras which enable users assess photograph’s histogram directly...
Abstract The three‐dimensional forest structure affects many ecosystem functions and services provided by forests. As forests are made of trees it seems reasonable to approach their investigating individual tree structure. Based on point clouds from laser scanning, a newly developed holistic is presented that enables calculate the box dimension as measure structural complexity using fractal analysis. It was found significantly different among tested species, belonging same species but...
Ecological research and an effective forest management need accurate information on the structure of canopy to understand biochemical, physiological biogeochemical processes within a forest. This paper reviews currently available instruments for measuring distribution biomass canopies. We compare most well-established approaches present different measurable parameters. A special focus lies resolution obtained data. It was found that only 3D laser scanners offer data with required by...
Abstract The proportion of mixed-species forests is presently increasing since they are commonly seen as providing a higher level many ecosystem goods and services than monospecific stands. This may be due to more complex three-dimensional distribution pattern plant elements, which has often been noted, but date rarely quantified. In the present study, we used terrestrial laser scanning data analyze relationship between tree species mixing stand structural complexity in three regions...
Automated species classification from 3D point clouds is still a challenge. It is, however, an important task for laser scanning-based forest inventory, ecosystem models, and to support management. Here, we tested the performance of image approach based on convolutional neural networks (CNNs) with aim classify seven tree 2D representation in computationally efficient way. We were particularly interested how would perform artificially increased training data size augmentation techniques. Our...
Laser scanning has revolutionized the ability to quantify single-tree morphologies and stand structural variables. In this study, we address issue of occlusion when a spruce (Picea abies (L.) H.Karst.) beech (Fagus sylvatica L.) forest with mobile laser scanner by making use unique study site setup. We scanned stands (1) from ground only (2) above using crane. also examined effect in summer (leaf-on) winter (leaf-off). Especially at canopy level stands, was very pronounced, were able its...
