Résumé :

WOODNET studies of a range of landscapes from forest and shrubland to agricultural landscapes where woody vegetation elements play a key role for conservation or service delivery. Novel satellite images at different resolutions, permitting to describe the internal structure of landscape elements, will produce improved resistance maps, considering landscape characteristics at different scales, and supported by species empirical data and models of habitat suitability, resource selection and landscape. New connectivity models based on a diversity of possible pathways for species movements through landscapes will be made. WOODNET also considers landscape legacies (past connectivity) on current species distribution. We will, for arable crops, study how landscape connectivity drives the distribution of pest and beneficial arthropods. The biological models are diverse, from bears and lynx for large landscapes dominated by forests or shrublands to beetles, plants, birds and damselflies for landscapes characterized by hedgerows. This will result in a diversity of functional networks with an evaluation of the synergies and antagonisms among them. This is an important point for discussion with stakeholders. In the landscape ecology research part of WOODNET we will decipher the different sources of scientific uncertainties, and their consequences on the design of the legal framework of GBIs. The involvement of stakeholders at different scales will permit to further discuss the links between research design and its outputs on GBIs implementation and management.
