The inland part of the site consists of arable cultivation and a gorge with cliffs, deciduous forest and scrub. The coastal delta includes brackish marshes and low, scrub-dominated hills. Human activities include arable agriculture, livestock-farming, recreation and hunting.
The site is important for breeding, passage and wintering waterbirds and raptors. Breeding birds include eight of the 21 species in Europe that are restricted (when breeding) to the Mediterranean biome. Species of global conservation concern that do not meet IBA criteria: Phalacrocorax pygmeus (wintering), Pelecanus crispus (non-breeding), Aythya nyroca (non-breeding), Gallinago media (passage).
