Other Site Characteristics

The site is mountainous, located in southern central Crete and covers part of the southern massif of Dikti in Iraklion Prefecture. It is delimited by Omalos plateau and Erganas stream on the north and by the contour of 700 to 800 m on the south including the southeastern peaks and slopes (Tourlou, Kynigou, Graspiasmasta etc) of Dikti mountains, the area of Ano Viannos in the south and Symi in the south-east.Springs and small intermittent streams are scattered throughout the site with Platanus orientalis and Nerium oleander riparian formations along the watercources. There is also a temporary pond at Omalos Viannou. The vegetation in most of the site is typical of Cretan calcareous cliffs and rocks, with phrygana and maquis (Q. coccifera) formations. There are also bare rocks and caves. Finally, there are Pinus brutia forests on the southern slopes and also cypress forests (Acero-Cupression), over 800 m.

4.2 Quality and importance

The total of the landscape and of the biotopes with the rare and endemic animals and plants compose a site with ecological and aesthetic value. The ecological importance lies on the existence of a range of habitat types, with a vegetation mostly at a good conservation status, from phrygana to maquis to forests to streams and ponds and to steep cliffs, screes and caves. The flora and fauna of these biotopes typically contains endemic and moreover local endemic species in Crete. Regarding the flora, there is the typical chasmophytic flora with rare and endemic species. The avifauna includes rare and protected birds of prey and the area is considered an important for the avifauna ecosystem at local level.
