Abstract

National Coastal Biocenosis Observation Network

Purpose

The aims of the benthic network (REBENT) are to collect and organise data relating to the distribution of coastal habitats and the monitoring of their flora and fauna, in order to provide a pertinent and coherent inventory for scientists, biodiversity manager and the public, and to detect changes over space and time. First established in Brittany after the Erika oil spill, REBENT Bretagne made it possible to implement long-term institutional monitoring for the application of the Water Framework Directive (WFD) along the coast of mainland France. In Brittany, the mostly closely-related monitoring operations were funded in part within the context of who state-regional contracts, first in 2000-2006 and then 2007 – 2013.
