Gentiane, Tabac d’Espagne, Decticelle… et tant d’autres !

Follow the Conservatoire d'espaces naturels des Hauts-de-France's volunteer curators and discover the rare Gentian pneumonanthe in the Marais de Berneuil sedge meadow, before admiring the summer flowering of the Vallée Monnet and its procession of insects: butterflies, locusts, grasshoppers, praying mantises...
