Assessment of the Regional Ecological Coherence Schemes (SRCEs) in France: what methodological contributions can be made to the identification and mapping of the French terrestrial and aquatic ecological network?

Abstract

The French terrestrial and ecological network (TVB for short in French) policy is based at national level on a framework document called "National TVB Guidelines" (ON TVB for short in French), whose objective is to ensure a national coherence of the TVBs, while leaving a free choice of method at each territorial level. At the request of the ministry in charge of ecology, the "scientific and technical support" department of the TVB Resource Centre has been carrying out a technical follow-up of the elaboration of the Regional Schemes of Ecological Coherence since 2010, in order to know the methodological choices of the regions and the way they approach the ON TVB. In 2017, the information collected in the context of this follow-up was the subject of an assessment of which this article reports the main results and draws the first lessons on the implementation of the ON TVB.
