In 2008, the French region of Rhône-Alpes completed the mapping of its regional ecological network. In order to support projects and initiatives which contribute to maintaining or improving ecological connectivity, the region offers so-called “corridor contracts”. Ideally, projects receiving support should involve several local authorities. Contracts are awarded for a period of five years. Support is provided for schemes which directly help to maintain or improve connectivity, as well as to schemes which aim to safeguard the elements of a biotope network in the long term via planning tools, environmental education and public relations work. A guide has been produced for prospective stakeholders which contains detailed information on the regional scheme and the contractual process.

Time of realisation for measure Immediate: The support becomes available immediately after the contract is approved and for a period of 5 years.
Impact scope Regional: The scope of impact and implementation can differ greatly depending on the project being promoted, however, as a rule, several local authorities should be involved.


Implementation period Long term: The contracts are concluded for a period of 5 years.

Economic and legal aspects

Costs High (100'000-1 Mio EUR): On average, support is available for 50% of the costs of the project. The highest subsidy rate is €1 million per contract or €200,000 per year. The overall budget for the region is set once the pilot projects have been evaluated.
Socio-economic impacts Medium: Dependent on the project being supported.
Sources of financing Public: regional
Legal situation A 5-year contract between one or several local authorities and the region.
