Other Site Characteristics

This site comprises a group of small rocky islets and the islet Thasopoula situated west and north of Skyros island, at the southearn part of the Sporades islands. Scrubs, phrygana and pine trees occupy the area. The marine area of the site surrounds the entire Island of Skyros, Including the uninhabited islets of Skyropoula, Rinela, Valaxa, Platela, Sarakino, 30 smaller Islets and rocks along, the southern, southwestern and western coast of Skyros, and the islet group of Podies and Pyrgoi in the north of Skyros. The marine area enclosing the islet of Prasouda, located approximately 30 km southwest of Skyros Island, Is also part of this site. The site boundary Is made up of a 1 n.m. marine extension along the southeastern coast of Skyros, Sarakino, Valaxa, Skyropoula and Prasouda Islets, a 2 n.m. extension along the northern and eastern coast of Skyros and the Islet group of Podies and Pyrgoi and a 2.7 n.m. extension around Rinela Islet. The Islets north of Skyros are volcanic, while the rest have a calcareous substrate. They exhibit large diversity of vegetation types and provide a variety of suitable nesting and roosting habitats for seablrds. The surrounding waters are very rich fishing grounds, which favour the presence of large seabird populations and marine mammals, such as the Sperm Whale, Rlsso's Dolphin, Striped Dolphin and Common Bottle-nosed Dolphin, as well as the Mediterranean Monk Seal.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

The site is important for breeding raptors, seabirds and species found in coastal scrub.The site is Important for all five seabird species of conservation concern In Greece. The local population of the Mediterranean Shag (102-104 pairs) is among the largest in Greece and together with the neighbouring populations of the Northern Sporades (GR065 and GR198) comprises one of the species main strongholds in the Aegean Sea. The post- breeding population is large (237-374 individuals) suggesting that wintering birds remain in the site. Mediterranean Shags feed primarily in coastal waters along the northern, western and southern part of the area. Audouin's Culls breed on uninhabited islets along the western, southwestern and southern coast of Skyros. During the breeding season Audouin's Gulls feed mainly in the vicinity of their colonies, while during the post-breeding season they disperse throughout the site and beyond, towards Ewoia island. The main Cory's and Yelkouan Shearwater colonies are located on islets southwest of Skyros. The Cory's Shearwater breeding population (81-156 pairs) Is estimated to be the second largest in the North Aegean Sea. These two shearwater species use coastal waters, including the continental shelf extending along the northeastern and eastern coast of Skyros for feeding, resting and rafting. The foraging range of shearwaters breeding on Islet
