  • Abundance categories (Cat.): C = common, R = rare, V = very rare, P = present - to fill if data are deficient (DD) or in addition to population size information
  • Data quality: G = 'Good' (e.g. based on surveys); M = 'Moderate' (e.g. based on partial data with some extrapolation); P = 'Poor' (e.g. rough estimation); VP = 'Very poor' (use this category only, if not even a rough estimation of the population size can be made, in this case the fields for population size can remain empty, but the field "Abundance categories" has to be filled in)

Other Site Characteristics

The site includes Syrna island and seven small islets situated south-east of the island of Astypalaia. They are very remote since all of them are found away from any large land mass and also they are surrounded by very deep sea.On Syrna island, the vegetation is mainly maquis, Juniperus phoenicea being the predominant plant. Today the islets are uninhabited, except for Syrna.Vertical seacliffs are present on all islets, even at the ones with the lowest altitudes; rarely is there a beach, and if there is one it is usually with pebbles. The only exception is on one islet of Tria Nisia group, south of Syrna, where there are extensive sand dunes on its northeast side. The vegetation of the cliffs is mostly composed by Aegean endemics, many of which are obligate chasmophytes.Falco eleonorae population values are based on LIFE - Nature «Δράσεις προστασίας για τον Μαυροπετρίτη Falco eleonorae στην Ελλάδα» (LIFE03 NAT/GR/000091)

4.2 Quality and importance

This area is important for passage migrants and breeding seabirds and raptors. Species of concern include: Calonectris diomedea, Puffinus yelkouan and Falco eleonorae.
