The areas of Carlingford Lough on the southern side of the dredged channel have been designated as a Special Area of Conservation (SAC).


This catchment is mostly structured by agriculture with mixed grazing pastures in upper stream and polders at the interface with the sea.


Principal economic activities in the Paiva are agriculture (particularly livestock), forestry, hunting and fishing. Associated transformation industries are also present in the catchment area. Tourism has growing importance.


The primary sector is predominant in the region, with an important seafood, fishing and bovine (semi-intensive) industry.
