Other Site Characteristics

This is a marine site that encompasses all the territorial waters of W and SW Crete. It is delimited in the north by the longitude of the northwestern point of Crete, which is the northern edge of the island Agria Gramvousa. It stretches all along the west and southwest coasts of Crete down to the longitude of cape Fragkokastelo, which is the south-eastern limit of the site. The site is characterized by a narrow band of shallow coastal waters inhabited by coastal marine mammals and a very steep slope of the continental shelf which rapidly falls down to depths exceeding 2000 m in the west and southwestern part of the site. Its waters form part of the Hellenic Trench, which is the perfect habitat for deep diving cetacean species. The vast majority of the coasts that border the site have not been disturbed by human activities and maintain most of their characteristics of wild nature. For this reason, seven Natura 2000 sites currently exist on the land of W and SW coasts of Crete.

4.2 Quality and importance

Cetaceans: The marine area of the site is very important for cetaceans and marine mammals in general. Six species inhabit the area. These are the bottlenose dolphin (Tursiops truncatus) and the monk seal (Monachus monachus) along the coastal shallow waters and the sperm whale (Physeter macrocephalus), the Cuvier’s beaked whale (Ziphius cavirostris), the Risso’s dolphin (Grampus griseus) and the striped dolphin (Stenella coeruleoalba) in the deep offshore waters. The site constitutes an extreme border for the range of the bottlenose dolphin (Annex II of the EEC/92/43), for which there is no proper coastal habitat in Europe southern than in the neighboring to the site island of Gavdos. Furthermore, the site is of extreme importance for the IUCN “Endangered” sperm whales and Cuvier’s beaked whales (both Annex IV of the EEC/92/43) and has been proposed by ACCOBAMS to be part of a Marine Protected Area for deep diving cetaceans along the Hellenic Trench. It is critical area for the entire Mediterranean sperm whale population (both breeding and feeding take place in the site) and constitutes one of the three hotspots of high densities for sperm whales along the Hellenic Trench. Marine habitat & invertebrates (subregion: IMERI KAI AGRIA GRAMVOUSSA - TIGANI KAI FALASARNA - PONTIKONISI, ORMOS LIVADI - VIGLIA): Posidonia oceanica meadows occur patchily, naturally restricted by steep slopes and wave exposure. Various facies of coralligenous assemblages (deep counterpart of Habitat Type 1170), including spectacular gorgonian facies (i.e. Paramuricea clavata, Eunicella cavolini) at depths between 85-105m, occur along the steep rocky coasts and reefs of the site. The foraminiferan Miniacina miniacea, common in both Posidonia oceanica rhizomes and the coralligenous communities, makes an important component of the biogenic sands in this area.
