4.1 General site character

Habitat class % Cover

Total Habitat Cover


Other Site Characteristics

This site comprises island Rinia and two small rocky islets (Tragonisi and Chtapodia) east of Mykonos island, at central Cyclades islands.This site includes the marine area surrounding the islands of Rineia and Delos, as well as a small part of the southwestern coast of Mykonos island, extending south of Cape Agios Georglos until Cape Closlda In Ornos Bay. It also contains the marine area surrounding Chtapodia islet located at the far east of the island. The site engulfs In total more than 15 islets and rocks. The boundary Includes a 0.5 n.m. marine extension in the western part and a 2.7 n.m. extension around Chtapodia. Currently it comprises one of the smallest marine sites in the Cyclades, however its boundaries are expected to be extended in the future since significant numbers of shearwaters regularly forage in the area around Mykonos. Rineia nowadays hosts only a few livestock pens and extensively cultivated cereal fields, while most of the Island is covered by phrygana and abandoned terraces. Delos comprises one of the most important archaeological sites in Greece, designated as a World Cultural Site since 1990. On the highest point of Chtapodia are the remains of observation pillbox, while a small pier and a church exist which are visited by locals and fishermen. The coastal area surrounding Rineia and Delos is very convoluted characterised by low-lying rocky cliffs Interspersed by sandy beaches and small coves with Posldonia beds. The waters are shallow, including numerous reefs and rocks and a gently sloping seafloor, with depths which do not exceed 100 m. Volcanic rocks on Chtapodia form eroding cliffs and significant scree habitats. To the north and east of Chtapodia, water depth Is greater, reaching a maximum of 200 m. The northern side of Mykonos and surrounding islets is exposed to strong north-northeastern winds coming directly from the open marine area of the Central Aegean Sea and Tsiknias Strait located between Tinos and Mykonos islands. The area provides suitable habitats for cetaceans; Common Bottle-nosed and Striped Dolphins have been observed here, while Risso's DFalco eleonorae population values are based on LIFE - Nature «Δράσεις προστασίας για τον Μαυροπετρίτη Falco eleonorae στην Ελλάδα» (LIFE03 NAT/GR/000091)olphins and Sperm Whale strandings have also been reported. A small Mediterranean Monk Seal breeding population Is also supported here.

4.2 Quality and importance

This is an important site for breeding raptors and seabirds.The site hosts Important breeding populations of three different seablrd species. A breeding population of Audouin's Cull was first recorded here in 1998 This is one of the rare occasions where the species nests on a larger island rather than on small uninhabited Islets. Colony size has remained stable over the last 15 years. The birds forage primarily along the coastal waters of Rineia, Delos and west Mykonos, but during the post-breeding season disperse in the wider area of Mykonos. Both Cory's and Yelkouan Shearwaters breed in the area. Colonies here, together with those located on islets around the central Cyclades (Paros, Naxos, Amorgos Islands), form the core shearwater breeding population of the Southern Aegean Sea (excluding Crete). These two species breed in a single moderately large mixed colony, sharing the same colony site, with nests dispersed between boulders, crevices within caves and under halophytic vegetation. The Yelkouan Shearwater breeding population, estimated at 100-250 pairs, is considered to be the second largest breeding colony in the Cyclades and the fourth most important on a national scale. Cory's Shearwaters also hold a significant colony here with 150-250 pairs. Both species have been observed feeding in large numbers in the region around Mykonos, with the largest flocks recorded in the marine area between Mykonos, Rineia and Tinos, in Tsiknlas Strait, as well as north of Chtapodia. The abundance of shearwaters in the area suggests that breeding birds from other sites also use the area for feeding. Additionally, the marine area between Tinos, Mykonos and Ikaria islands comprises an important passage for both species of shearwater moving between their colonies in the Central Cyclades and the Dodecanese and their foraging areas in the Central and Northern Aegean Sea.
