4.1 General site character

Habitat class % Cover

Total Habitat Cover


Other Site Characteristics

The terrestrial part of the site is combination of a long beach with small dunes and floodplain forests. In the marine part of the site are included the Islands of Sv. Ivan and Sv. Petar. Island of Sv. Petar - There is a lighthouse with little farms around it. There are a few fishing huts in the west and one in the eastern part of the island. The territory is taken by thorny bushes where hare colonies are found. On the island are gazing cows and goats. The island is completely ruderalized. There are numerous hare colonies on the island. Only on the coastal rocks (with inclination 30-90%) to the sea are seen representatives of the coastal rocky vegetation. The island is used by fishermen and during the summer season for one-day trips. Island of Sv. Ivan - Completely ruderalized. Only Chenopodiaceae species. Waterless island, covered with guano by the gulls with layer thickness between 10-15 cm. Place for breeding. Only on the coastal rocky splits are found individual representatives of rocky vegetation. The island is not visited. The site is under strong tourist impact.

4.2 Quality and importance

The site is important for the existing of invertebrate fauna, different coastal habitats, especially habitat type “humid dune slacks”. The southern part of the bay of Sozopol includes one of the largest deposits in the region of subtype 1110-1 “underwater meadows with sea grasses," which is in relatively good ecological condition and has good prospects for achieving and maintaining favorable conservation status. The islands in the site are the only natural habitat of the Yellow-legged Gull (Larus cachinnans) remaining on our sea coast. Island of Sv. Petar – the populations of Goniolimon and Limonium are small in a state of progressive nitrification. There is no old information about the situation of the natural environment on the Island of Sveti Petar and comparison cannot be made. The forecast is unfavorable - continuing dying of the natural flora and in the best case preserving of some fragments of the cliff zone. Island of Sveti Ivan - species with conservation value are found on the island. On the Bulgarian seacoast there is not an analogy to the specific mezoconditions that exist on the island of Sveti Ivan and although it is close to a settlement it is not visited. It could be used as an ecological model of the processes of complete nitrification. The processes are natural.
