Other Site Characteristics

Diapontia is a small island complex situated at the north-westernmost part of Greece, in the NE Ionian Sea. The complex consists of three main (populated) islands (Othonoi, Erikousa and Mathraki) and some smaller uninhabited rocky islets (Trachia, Platia, Diaplo, Diakopo). This fully marine site extends at depths of 0-50 m and covers an area of 153.38 km2. This marine area is characterized by the existence of Posidonia beds, mainly in depths between 5-30m.

4.2 Quality and importance

The site comprises important Posidonia oceanica beds (Habitat Type 1120), infralittoral and circalittoral rocks and boulders (Habitat Type 1170), as well as detritic sediments and rhodolith beds (Habitat Type 1110). Llittoral biogenic rims of Dendropoma / Neogoniolithon occur along the most exposed rocky shores of the islands (HCMR, 2013).
