Abstract
The ecological network concept brings with it a new approach in terms of conservation and has received attention from both the lawmaker and the developers, with its focus on conservation and restoration of the ecological continuum and ordinary biodiversity. The implementation of the corridors remains however difficult, as they are not necessarily based on clearly identified formal structures. How to reconcile, in this context, the ecological challenges with the economic, urban or agricultural development of the territories? How to make operational the aims defined in the regional Scheme for ecological coherence- Green and Blue Belt (SRCE-TVB)? Is it possible to rely on the public and parapublic landowners to translate the ecological continuum? The aim of the project is to elaborate a methodology to map ecological corridors which confront, on the scale of the plot, the ecological issues with the territory development dynamics. The methodology will have to be scalable and transposable to other territories. The project is built around: • the identification of the potential ecological corridors from a landscape approach; • the evaluation of the ecological functionality of potential corridors through a qualitative approach and a quantitative approach; • the evaluation of the corridors’ efficiency from the point of view of feasibility and structure sustainability. Three types of results are expected: • a decision-making support tool to facilitate choices in terms of corridors scenarii; • ecological continuity scenarii on the scale of the Saint-Omer urban community territory; • a measure of the degree and quality of potential intervention of landowners.
