    (i) Context:The ICP Forests database is probably the most comprehensive forest ecosystem database in Europe and contains the accumulated results of several decades of harmonised monitoring all over Europe. (ii) Aims: Goal of this paper is to open the soil information of the ICP Forests Level II plots for broader use among forest scientists. (iii) Methods: The soil data were gathered according to the ICP Forests manual, purified, validated, and aggregated to meaningful variables and summarizing soil properties. (iv) Main features and potential use of database: The aggregated Level II forest soil database provides the occasion for the combined evaluation of up to 130 unique soil variables per plot with dynamic data on tree growth, ground vegetation, foliage chemistry, crown condition, tree phenology, leaf area index, ground vegetation, ozone injury, litterfall, soil solution, deposition, ambient air quality, and meteorological data assessed on the same plots. (v) Conclusions:The database covers nearly all member states of the European Union, but it is not representative for this area in terms of tree species and soil types due to the original selection criteria for the plots.

    This data set provides unique empirical data from triplets of Scots pine (Pinus sylvestris L.) and European beech (Fagus sylvatica L.) across Europe. Dendrometric variables are provided (Table 2) for 32 triplets, 96 plots, 7555 trees and 4695 core samples. These data contribute to our understanding of mixed stand dynamics.

    This dataset has been developed during the A2 Action of the SelPiBio LIFE project (www.selpibio.eu). The main aim of this project is demonstrate the effects of two thinning regimes, selective and from below, on soil biodiversity in young black pine stands. To evaluate the effect of thinning on analysed pinewoods, eighteen monitoring areas of 1 ha each were designed and realized across two study areas in Tuscany (Central Italy), the Pratomagno mountain chain and the Monte Amiata (Fig.1). In each study area, 27 circular plots of 15 metres of radius were geo-referenced (3 for each monitoring area). All the included trees were measured and data were collected between 2015 and early 2016 to characterize the horizontal and vertical structure of studied forests.

    Bilan de santé du sapin pectiné dans le massif jurassien, effectué sur 208 placettes de 6 sapins réparties régulièrement sur le massif jurassien, avec relevé de végétation, données stationnelles (topographie, description de sols), données dendrométriques (hauteur, circonférence, concurrence en cime des arbres carottés), données sanitaires (transparence et jaunissement des houppiers, présence de gui et de gourmands)... Il a montré leffet prépondérant des sécheresses sur la santé des sapins jurassiens et une augmentation de leur croissance radiale à long terme considérable à relier à la modification de l'atmosphère et du climat à l'échelle de l'hémisphère nord, et à ses impacts sur les écosystèmes forestiers

    En 1982 et 1983, Denis Girault a effectué 400 relevés de végétation dans des forêts des Crêtes Pré-ardennaises qui lui ont permis de publier en mai 1985 le catalogue des stations forestières de cette région.
