About the susceptibility of commercial trees to roe deer browsing

Ballon, P. et al. (1995)

In order to better understand the susceptibility of some commercial trees to roe deer browsing, we observed the feeding behaviour of tamed animals. Through our experiments it appears that broadleaved species are much more prefered than coniferous ones. Oak transplants from nurseries are prefered to ...

Contrôler la végétation en plantation forestière : premiers résultats sur les modifications micro-environnementales engendrées par l'utilisation de plantes de couverture

Provendier, D. et al. (2004)

Young tree establishment in forest plantation is often compromised by herbaceous vegetation competition. At present, this vegetation is generally controlled by chemical or mechanical operations but they are criticized either from environmental points of view either for their efficiency. In this ...

Evaluation of the effect of accessibility on forest stand structure with airborne laser scanning data and GIS-based models

Bellier, J et al. (2014)

While numerous works have shown that the road network impacts forest biodiversity, there is a lack of hindsight regarding how forest accessibility affects forest structure due to the possibility of human intervention through harvesting. In a context of growing demand for woody resources, it is ...

Contrasting spatial and temporal responses of bird communities to landscape changes

Bonthoux, S. et al. (2013)

Quantifying the impact of land-use changes on biodiversity is a major challenge in conservation ecology. Static spatial relationships between bird communities and agricultural landscapes have been extensively studied. Yet, their ability to mirror the effects of temporal land-use dynamics remains to ...

Exploring the "last biotic frontier": are temperate forest canopy special for saproxylic beetles?

Bouget, C. et al. (2010)

Conserving saproxylic beetles in a complex forest landscape will require knowledge about the habitat requirements of most species to prioritize actions or to make informed decisions. As well as tropical forests, temperate forests are also stratified but patterns are similarly not well established. ...
