The Gruissan Botanical Society (Les Amis du Pech Maynaud) was founded 1996, and exists to study and protect the local flora.

The botany of Gruissan and (to some extent) Narbonne is unique. For this reason, cataloguing and protecting it is necessary and urgent. A small group of friends was formed for this purpose and, after a while, this became "Les Amis du Pech Maynaud".

Now the society has over one hundred members, who ramble in the area in every season.
