FR831COR157 - Etang d'Arje Vecchie
Description
L’estuaire de la rivière Petrignani est situé entre le village de Moriani et au sud de Santa-Lucia-di-Moriani, sur la commune de San Nicolao. La présence d’eau douce est permanente, bien que qu’il soit probable que l’eau soit saumâtre à l’embouchure. La connexion avec la mer est sèche en été. La rivière est traversée par la route T10 via un pont. La végétation dominante est composée d’Arundo donax et de phragmites. Les berges sont peuplées par des aulnes. La pêche à la truite est pratiquée en amont de la rivière. Les activités principales du bassin sont agricoles (culture de clémentines notamment). (Inventaire le 31/03/2019 par T.
