Mont Lachat is a Sensitive Natural Area (ENS). This is an area recognised for its natural heritage, but which is threatened and/or vulnerable due to urbanisation or the proliferation of industrial activities. The Mont Lachat ENS has been the site of daring efforts to rehabilitate and renaturate the site. After dismantling an old wind tunnel, the soil was reseeded with a mixture of local seeds. A total of 5,000 square metres was restored by September 2015. For a site located at an altitude of 2,000 metres, at the foot of a glacier and exposed to the wind, this was truly an unprecedented scientific experiment.
