International audienceEcological network concept is a growing core element of conservation strategies. Based on the need to integrate ecological processes which underlie spatial dynamics of biodiversity at a landscape scale, network planning is largely based on a single model that allows the identification of natural core areas and linkage corridors. In this context a structural mapping approach is the most often used means to discuss and identify conservation issues at stake and to prepare recommendations for action. In this paper we analyze the process of ecological network construction at the scale of a Regional Natural Park in southern France. We show that by sticking to a classical and highly technical approach focused on mapping spati...
