While sustainable forestry in Europe is characterized by the provision of a multitude forest ecosystem services, there exists no comprehensive study that scrutinizes their sensitivity to management on pan-European scale, so far. We compile scenario runs from regionally tailored growth models and Decision Support Systems (DSS) 20 case studies throughout analyze whether service depends intensity other co-variables, comprising regional affiliation, social environment, tree species composition....

Summary Exotic tree species are widely used in forest plantations for their often high productivity and performance compared to native trees. However, these advantages may be compromised by herbivore damage. A list of European insect that have expanded host range one 28 exotic introduced E urope was compiled from a systematic literature review. The number successful expansions analysed using three predictors: (i) phylogenetic relatedness between species; (ii) area covered Europe; (iii) time...

The world’s forests have never been more threatened by invasions of exotic pests and pathogens, whose causes impacts are reinforced global change. However, forest entomologists pathologists have, for too long, worked independently, used different concepts proposed specific management methods without recognising parallels synergies between their respective fields. Instead, we advocate increased collaboration these two scientific communities to improve the long-term health forests. Our...

Abstract The demand for wood in Europe is expected to increase the coming decades. However, any theoretical maximum supply will be affected by sustainability constraints, motivations of forest owners and regional factors, such as incentives, species assortments. influence these factors on changeable.

Climate change poses a major challenge for forest management in Europe. Understanding how forestry professionals perceive climate is critical to inform decision-making on adaptation. The aim of this study was explore the perceptions regarding and its effects forests, as well importance different strategies Using survey, which we received 565 [retained] responses, determined regional differences across nine European countries six professional groups.

Abstract Europe has a history rich in examples of successful and problematic introductions trees with native origin outside (non-native trees, NNT). Many international legal frameworks such as treaties conventions also the European Union have responded to global concern about potential negative impacts NNT that may become invasive natural ecosystems.

We collected information on native and attacking trees, i.e. type, extent time first observation damage for 23 important trees in 27 European countries. Our database includes about 2300 synthesised records (synthesised per biotic threat, country) from over 800 species. Insects (49%) fungi (45%) are main observed threats, but also...
