Combining low-density LiDAR and satellite images to discriminate species in mixed Mediterranean forest

Using a combination of remote sensing data, Pinus pinaster Ait. and Pinus pinea L. were distinguished at individual tree level in mixed Mediterranean stands with over 95% accuracy. This approach is easily applicable over large areas, enhancing

Tree and stand level estimations of Abies alba Mill. aboveground biomass

We provided a complete set of tree- and stand-level models for biomass and carbon content of silver fir Abies alba. This allows for better characterization of forest carbon pools in Central Europe than previously published models. The

Base cation dynamics in rainfall, throughfall, litterflow and soil solution under Oriental beech (Fagus orientalis Lipsky) trees in northern Iran

Fluxes of base cations were studied in an Oriental beech forest and an adjacent forest gap. The fluxes of base cations in throughfall, litterflow, topsoil and subsoil solution were higher in a mixed Oriental beech forest compared

Performance of alternative spatial models in empirical Douglas-fir and simulated datasets

Based on an empirical dataset originating from the French Douglas-fir breeding program, we showed that the bidimensional autoregressive and the two-dimensional P-spline regression spatial models clearly outperformed the classical block model, in terms of both goodness of

Patterns of hybrid seed production in adjacent seed orchards of Acacia auriculiformis and A. mangium in Vietnam

Hybrid seed production in adjacent seed orchards of Acacia auriculiformis and Acacia mangium was influenced by (i) flowering times of the two species and (ii) the distances of parent trees from the inter-orchard boundary. Approximately 80% of

Site- and tree-related factors affecting colonization of cork oaks Quercus suber L. by ambrosia beetles in Tunisia

Ambrosia beetles are emerging globally as important agents of tree death and decline. In this work, we observed highly variable attack intensity by ambrosia beetles in cork oak stands in Tunisia. A correlation between the proportion of

Elevation modulates the phenotypic responses to light of four co-occurring Pyrenean forest tree species

Elevation markedly modified the species-specific phenotypic responses of trees to light. The effects from elevation mostly occurred at organ level (SLA) for the montane species, but at whole-plant level (allocation traits) for the subalpine ones. The subalpine

A general method for the classification of forest stands using species composition and vertical and horizontal structure

We present a novel approach to define pure- and mixed-forest typologies from the comparison of pairs of forest plots in terms of species identity, diameter, and height of their trees. Context Forest typologies are useful for many

NFIWADS: the water budget, soil moisture, and drought stress indicator database for the German National Forest Inventory (NFI)

The NFIWADS database contains aggregated results for the German National Forest Inventory (NFI) plots based on process-based water balance simulations. More than 150 water budget, soil moisture, and drought stress indicators were derived for mature, closed-canopy beech

Stand and environmental data from Pinus halepensis Mill. and Pinus sylvestris L. plantations in Spain

This data set provides valuable environmental information about Pinus halepensis and Pinus sylvestris plantations in Spain. An array of 74 physical, chemical and biochemical soil (organic horizon and 10 cm topsoil), climatic, physiographic and stand variables from
