Recreation of ecological networks mutualized compensatory measures and visit of the National Natural Reserve of the Grand Lemps peatland

The Department of Isère coordinated a project of restoration and conservation of 6 wildlife corridors in the Grésivaudan Valley and the Voreppe Gorge between 2008 and 2015.

These two sites were identified as priorities in the Isère ecological network in 2001. Two studies were conducted in 2004 and 2006 by the Grenoble Region’s Urban Planning Agency and the Swiss research firm Econat to define the corridors and the actions to be implemented. Following these studies, a working consultation was held with both the financial partners (Europe, Rhône-Alpes Region, the Water Agency and AREA) and technical partners (municipalities and inter-municipal districts, hunting and fishing associations, Chamber of agriculture, and LPO).

This "Corridors of Life" project also included advocacy, communication, management of the corridor space and actions to mitigate points of conflict: creation of a small wildlife passage, developments on and under motorways but also the installation of wildlife detectors or two developments under county (departmental) roads.
