At the level of watersheds (Aude, Berre and Corbières-Maritime), SMMAR through the development of the strategic management plan for wetlands wishes to perpetuate the services rendered or offered, actual or potential, by wetlands and to define a hierarchy of the latter. The plan is put in place in a concerted approach to bring together all the actors of the territory sensitive to the conservation of wetlands. They should be involved in this project. For this, 2 SMMAR agents are in charge of the animation and the follow-up of the operation.
