Audomarois Marshes


The Audomarois marsh is located at the junction between the Artois and Flanders. Vast of 3726 ha, rich of 700 km of canals, picturesque landscapes, 300 species of plants including 40 protected by law, more than 200 species of birds, 26 species of fish, it is truly a privileged site.
However, modern farming techniques and new social practices threaten this unique area, the only cultivated marsh in France.

Local actors considered it their responsibility to take charge of the future of this exceptional area in order to ensure its preservation and transmission under good and safe conditions to future generations.

For more than 10 years, their commitment has been demonstrated by concrete actions of restoration, enhancement and education. Two objective documents have already been published and have exceeded expectations in terms of positive benefits for the territory. In particular, the increasing participation of local associations, partners and inhabitants, but also recognition beyond our borders, such as the Ramsar site and the Biosphere Reserve, constitute important awards and recognition of the specific features of the territory and our work.
