Other Site Characteristics

Northern Sporades are a group of islands situated in the NW Aegean, on the north of Evvoia island and on the east of Pilion peninsula. The site includes the SE part of Skopelos and the island of Alonnisos, the only inhabited parts of the site and a number of smaller islands and islets, which are uninhabited, with the exception of the few guards and the occasional cattle-breeders. The largest part of the site is covered by marine habitats, not included in the Annex I habitat types. Geologically, all the islands are dominated by limestone with the exception of Psathoura, which has a clearly volcanic origin. Near Psathoura there are the remnants of an old volcano. The earthquakes of 1867-1868, 1965, and 1973 were destructive. As a result, the population of the old village (Chora) of Alonnisos moved to the harbour, creating the new village of Patitiri. The highest peak in SE Skopelos is Paliouri (546 m). Steep valleys and seasonal torrents are formed on the island. The vegetation consists mainly of Aleppo pine forets, Quercus coccifera maquis, a small forest of Quercus ilex, an Oleo-Ceratonion community, and orchards and olive trees.The highest peak in Alonnisos is Kouvouli (493 m). The vegetation consists mainly of dense maquis with Quercus coccifera, Q. ilex, Arbutus unedo, Juniperus phoenicea (a tall arborescent maquis, Aleppo pine forests, and phrygana (Sarcopoterium spinosum). The pine forests at Skopelos and Alonissos replaced the once dominant oak forests because the pines were supported due to their use in ship-building. The highest peak in Peristera, a mainly rocky island, reaches at 260 m. The vegetation at the central and southern part consists of olive trees, while in the north there is a dense maquis with Quercus coccifera, which suffered by intensive grazing in the past.The highest hills on the island of Kyra Panagia (300 m) are separated by a valley connecting the two main bays of the island, Planitis and Agios Petros, which are the safest ports in N. Sporades. The main vegetation consists of maquis with Pistacia lentiscus, Quercus coccifera, Atbutus unedo, Erica verticulata and olive trees and there are abandoned fields colonized by Vicia viscosa and Mentha pulegium. The highest peak in Gioura island, and in the whole site, reaches at 570 m. The vegetation mainly consists of phrygana (Sarcopoterium spinosum and Euphorbia acanthothamnos). In the middle of the island there is a Quercus coccifera forest. In the central and northern parts of the island, dolines dominated by Crataegus monogyna have been formed. In the cliffs of Gioura a large number of chasmophytic species can be found.The maximum altitude on Psathoura island does not exceed 17 m. The vegetation differs from the one of the other islands, with sparse phrygana (Sarcopoterium spinosum), Olea europea var. sylvestris and Pistacia lentiscus.The embryonic sand dunes and the semi-aquatic habitats host a relatively large number of flora specie (130), not observed on the other islands.The highest altitude in Skantzoura island is 107 m. The vegetation includes Juniperus phoenicea matorral, Sarcopoterium spinosum phrygana, and maquis. The islets around Skantzoura are covered by Euphorbia acanthothamnos phrygana.The highest altitude in Piperi island reached at 353 m. The island is covered mainlny by Pinus halepensis forest, maquis, and phrygana. Many chasmophytes grow on the sea cliffs of Piperi. The site includes marine areas surrounding Alonnisos island, the uninhabited islands of Peristera, Kyra Panagia, Gioura, Piperi, Psathoura and Skantzoura and the nearby islets of the Northern Sporades, as well as the eastern part of Skopelos island from Skopelos Bay on the northern side of the island up to Cape Veloni on the south of Skopelos. Inaccessible cliffs and islets are the main nesting sites for all common seabird species in Greece, including the Mediterranean Shag, Audouin's Gull, Yelkouan Shearwater and Cory's Shearwater, all of which use the surrounding marine areas for foraging and resting, Due to the large number of shearwaters foraging in the area, it is expected that Yelkouan and Cory's Shearwaters from other regions in the North Aegean visit the site to feed, The area is also important for marine mammals, such as cetaceans and the Mediterranean Monk Seal. The area supports a large population of the latter, considered to be the most important for the species in the Mediterranean Sea, Posidonia beds extend along the coast of Alonnisos, Kyra Panagia and Psathoura.

4.2 Quality and importance

The part of the Northern Sporades included in the site, which covers the National Marine Park, represents a unique in the Mediterranean complex of terrestrial and marine habitats. It contains a variety of vegetation types -especially marine priority habitat types of excellent representativity-, and of flora and fauna species, among which many are endemic, rare, or protected, and some are at their southern- or northern-most limits of distribution. The island of Piperi is protected by the Barcelona Convention. Besides the scientific and educational interest of both the marine and the terrestrial area, the site also presents a great archaeological interest with relicts covering the prehestorical, the classical, and the byzantine ages (cave findings, shipwrecks, old monasteries, and churches).The ecological quality and importance of the site and especially its biological diversity potential are made evident by the following detailed description:Fauna:The numerous caves with beaches formed at the sea cliffs of the islands consitute ideal shelters for the Monk seal population, which is estimated to be the most important in the Mediterranean. Piperi, the most important breeding area for the Monk seal, is the core area of the National Marine Park of Sporades.An isolated population of Capra aegagrus ssp. dorcas (included in section 3.2.c. as C. aegagrus) lives exclusively on Gioura. OTHER IMPORTANT SPECIES WITH MOTIVATION: The following species are protected by the Greek Law (Presidential Decree 67/81) and are included in the IUCN Red Data List (1993) in the category of threatened plants: Callitriche brutia is a European species, found in Psathoura and Agios Efstratios in Greece. Campanula chalcidica is balkan endemic found in Athos and Yioura in Greece. Evax contracta occurs in the S. Aegean in Greece and in Europe, otherwise in Asia. Filago aegaea ssp. aristata is a plant with distribution in S & E Aegean, Ionian Islands, Crete and Cyprus. Lythrum borysthenicum is a species of C & S Europe, very rare in the Balkan peninsula (Flora Europaea).Note: The IUCN characterizations given concern the plants status in Greece unless otherwise stated. Malcolmia flexuosa ssp. naxensis is endemic to the Aegean region and Anatolia. Silene fabaria is an Aegean region endemic (occurring only in W Anatolia out of Greece).The Mediterranean Shag breeding population (85- 134 pairs) is one of the largest in Greece. Nesting sites are dispersed throughout the entire site in small and medium-sized colonies. Mediterranean Shags forage mainly in coastal waters close to their colonies, After the breeding season a significant proportion of birds leave the marine area of the site. Increased post-breeding congregations in the neighbouring regions, i.e. Skyros and Skiathos islands, as well as colour ring recoveries, which were found up to 200 km away from nesting sites, suggest post-breeding dispersal of Mediterranean Shags in a wider region of the Northern Sporades. Several Audouin's Gull breeding sites have been located in the area during the last 15 years. Different nesting sites tend to be used over consecutive years, Audouin's Gulls forage and rest primarily in coastal waters adjacent to their colony sites during the breeding season but disperse throughout the Northern Sporades and beyond during the post- breeding season. The entire marine area of the site, particularly east of Alonnisos, is used by Cory's and Yelkouan Shearwaters for feeding and resting, In the Northern Sporades both shearwater species breed in small and medium-sized colonies and use waters adjacent to their colonies primarily for the formation of rafts before entering colonies at night. The total estimated number of Yelkouan and Cory's Shearwater breeding individuals in the area Is small compared to the total estimated number of birds that regularly forage in the area. It Is therefore anticipated that Cory's and Yelkouan Shearwaters from other colonies in the Northern or potentially Central Aegean Sea visit the site to feed. Additionally, large foraging congregations have been recorded to the east (i.e. towards Skyros island) and to the north (i.e. towards Chalkidiki) of the site.
