Other Site Characteristics

Cetaceans: The site consists of Nestos Delta and Keramoti lagoons and all the sea area of the wider Thasos channel and Kavala Gulf, with the exception of the very coastal waters of the urban part of Kavala and Nea Karvali. To the west and south-west the site is delimited by the straight line that links the beach of Elaiochori Kavalas with the cape Prinos in Thasos Island. To the east the site is delimited by the west side of the port of Avdira and to southeast by the cape Pyrgos of Thasos Island. The shallow and very productive waters of the marine area of the site constitute important part of the habitat of the local small harbour porpoise population (Phocoena phocoena). They are also inhabited by two more coastal cetacean species: the bottlenose dolphin (Tursiops truncatus) and the common dolphin (Delphinus delphis). The nearest to the wetland towns and villages are Keramoti and Chrysoupolis while Kavala is situated 25 km and Xanthi 16 km away from the wetland. River banks are sandy with extended softwood and riparian forests. Moreover, a mosaic of habitats at the mouth of the river, composed by reedbeds, Tamarix scrubs, inland as well as large coastal dunes. There are several greater lagoons with salt marshes around, where in the area of Chrysoupolis there are freshwater lakes with reedbeds and water lilies. There, is also found a rocky islet (island of Thassopoula). At the adjacent gorge of Nestos, rich vegetation grows on the steep cliffs and diverse fauna is provided with shelter. Information on the site in relation to Avifauna is coming from the description of the wider IBA area GR250 (see documantation): This proposed marine IBA, situated within the Gulf of Kavala and around Thasos island, Is one of the most important areas for seabirds in the Northern Aegean Sea. The site Includes the entire Gulf of Kavala, the Strait of Thasos, coastal waters in the east adjacent to the Delta of River Nestos, a marine strip along the southern coast of Thasos up to Cape Stavros, and finally the coastal area along the mainland from Nea Peramos up until Drakopetra to the west. Apart from the central part comprising of the Gulf of Kavala and Thasos Strait, the area also contains a 1 n.m marine extension along the western coastal section and a 0.5 n.m. extension along the southern coast of Thasos. The boundaries of the proposed IBA adjoin with those of the existing IBA 'Nestos delta and coastal lagoons' (GROT 2). The largest part of the area extends over a shallow plateau with depths up to 50 m. This is one of the most important fishing grounds In Greece, with extensive Posldonia beds. Cetaceans, primarily dolphins and the Harbour Porpoise, as well as Mediterranean Monk Seals are regularly observed in the area. Important foraging areas regularly hosting significant numbers of shearwaters extend south and eastwards beyond the boundaries of the proposed marine IBA. Thus, it Is expected that future surveys will provide additional data supporting the extension of Its boundaries towards these pelagic areas.

4.2 Quality and importance

Cetaceans: The marine area of the site is considered of extremely high importance for populations of rare, endangered and vulnerable cetaceanss: the harbour porpoise (Phocoena phocoena) the bottlenose dolphin (Tursiops truncatus) and the common dolphin (Delphinus delphis). The most important characteristic of the site is the high density (in comparison to the rest of the north Aegean Sea) of the small, resident and endangered harbour porpoise population, which is the only population of the species surviving in the entire Mediterranean Sea. Until this population was discovered, the species was considered extinct from the entire Mediterranean Sea. Together with the sea area of Alexandroupolis, the site constitutes the most important spots of the national territory (and the Mediterranean in general) for the survival of this species. The high productivity of the marine environment offered by the neighboring river deltas and the large plateau of the Thracian Sea create a perfect habitat also for the two coastal dolphin species: bottlenose dolphin and common dolphin. Apparently for trophic reasons, their local population units seems to be still thriving if compared with populations southern in the Aegean or in the Ionian Sea. Therefore, they are considered as important population stocks not only for the Aegean Sea, but for the entire eastern Mediterranean Sea. The harbor porpoise is listed in Annex II of the Directive 92/43/EEC and is also included in the Bern, Bonn and CITES conventions, in the Greek Red Data Book (endangered species) and is also protected by the Greek legislation (Presidential Decree 67/1981). The Mediterranean population of harbor porpoises is classified as Endangered in the IUCN Red List of Threatened Animals and as priority/key species in the ACCOBAMS agreement. The bottlenose dolphin is also listed in Annex II of the Directive 92/43/EEC. Both the bottlenose dolphin and the common dolphin are protected species according to 92/43/EEC Directive and are also included in the Bern, Bonn and CITES conventions, in the Greek Red Data Book and are also protected by the Greek legislation (Presidential Decree 67/1981). The Mediterranean population of common dolphins is classified as Endangered in the IUCN Red List of Threatened Animals and as priority/key species in the ACCOBAMS agreement. The wetland is important from ornithological point of view because of the big extense it occupies and because of its rich habitat types. Moreover, it is a valuable part of a wetland chain included between Axios river and Delta Evrou in northern Greece. The riparian forest and the coastal area are important for breeding, the lagoons for migrating and the river for the wintering of many species as grebes, ducks, herons, cormorants, pygnies, raptors, geese, flamingos, waterfowl and others. The reference on Leuciscus cephalus is about the subspecies macedonicus. Concerning the fauna the quality of the site is indicated by the invertebrate Araschnia levana which is the southern edge of extension, the invertebrate Lycaeides argyrignomon which is refered to Koomen P., van Helsdingen P.J. 1993. Listing of biotopes in Europe according to their significance for invertebrates. Council of Europe and the invertebrate Maculinea alcon which is refered to IUCN Conservation Moniotoring Centre 1988. IUCN Red List of Threatened Animals. In the present site Salvinia natans, a plant species included in WCMC as well as Leymus racemosus ssp. sabulosus, a plant taxon which reaches its extreme distribution limit in Northern Greece, are growing wild. Information on the site in relation to Avifauna is coming from the description of the wider IBA area GR250 (see documantation): The proposed marine IBA Includes seaward extensions for some of the largest and most important Mediterranean Shag colonies in Greece, located on uninhabited islets and Inaccessible coastal cliffs. The local breeding population represents more than 10% of the national breeding population of the species and its main colony sites have already been included In terrestrial IBAs (GROT 2 and GR016). Additionally, it is estimated that more than 17% of the national wintering population spends the post- breeding period In the area. Based on the results of boat-based surveys, telemetry and ring recoveries it has been confirmed that Mediterranean Shags disperse throughout the entire area of the proposed IBA In search of food. Since the area is characterised by shallow waters, the species foraging areas are not exclusively restricted to the coastal zone. Abundant schools of small and medium-sized pelagic fish, such as anchovies and sardines, attract pelagic seabirds, primarily Yelkouan Shearwaters. Flocks consisting of several tens to several hundreds of individuals regularly feed in the entire area of the proposed IBA. However, large foraging concentrations of Yelkouan Shearwaters have also been recorded In pelagic areas beyond the eastern and southern boundaries, indicating that some significant foraging areas of the species around Thasos remain to be Included. Therefore, further surveys are considered essential In order to delineate them. Since no breeding colony of the species has been located In the area, it Is assumed that these shearwaters come from colonies found in the northern and potentially central Aegean Sea. The highest numbers of Yelkouan Shearwater have been recorded in the area during the winter months when birds return from the Black Sea to their breeding sites In the Aegean Sea and the rest of the Mediterranean Sea, however significant foraging congregations are recorded during the breeding season as well.
