This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern. [source:]

Mediterranean Shag[Mediterranean Shag (Phalacrocorax aristotelis desmarestii) Europe 2007]
The Mediterranean Shag Phalacrocorax aristotelis desmarestii is a subspecies endemic to the Mediterranean basin. Despite their numbers are not well known experts agree that a reduction of the population has taken place. It is a seabird species linked to the coast where it breeds in rocky areas. The Mediterranean population of the species is included in Annex II of the Bern Convention, and the subspecies is listed in Annex I of the Birds Directive 79/409. This Action Plan relies largely on the results of a Workshop on the subspecies held in the Balearic Islands, on September 1999. The species is sedentary and partially dispersive, but generally philopatric. Only through adequate management at local level it would be possible to ensure the survival of all populations. Numbers and trends of the main colonies of the species are still unknown.
