The project for the animation of NATURA 2000 Grande Brière — Marais de Donges and Brivet sites carried out by the Mixed Trade Union of the Regional Natural Park of Brière concerns the implementation of the actions defined in the objective documents of the two Natura 2000 sites for the period from 1 February 2018 to 31 January 2020. It aims to promote concerted management between the actors involved in natural areas to enable the species and habitats that have justified the designation of the site to be maintained in good conservation status.
