The Pomorie Lake is a natural hyper-saline lake – a sea coast lagoon, part of which has been converted to salt ponds. Also, it includes salty marshes and reed fields. Together with the Burgas wetlands, the lake forms the largest and most significant conservation complex along the southern Black Sea coastline. The area includes the estuary of the Aheloi River.The total Ramsar site area is 921,5 ha.Protected territory since 2011. In 2002 the lake is proclaimed for a wetland with international importance according to the Ramsar convention. In 1989 the territory is designated as an Important Bird Area and in 2007 it became part of the Natura 2000 network: Protected Site “Pomoriysko ezero” with code BG0000152 according to the Bird Directive and Protected site“Pomorie” with code BG0000620 according to the Habitat Directive.The following natural habitat types of significance for conservation, according to the Biodiversity Act and to the Habitats Directive have been established: 1150 Coastal lagoons; 1160 Large shallow inlets and bays; 1170 Reefs; 1310 Salicornia and other annuals colonizing mud and sand; 1530 Pannonic salt steppes and salt marshes; 2110 Embryonic shifting dunes; 2120 Pannonic dunes along the shoreline with Ammophila arenaria (white dunes); 92D0 Southern riparian galleries and thickets (Nerio-Tamaricetea and Securinegion tinctoriae).

This is the first map of sandbanks in Bulgarian Black Sea drawn based on expert interpretation of the following data: point data on the type of substrate (sediments, hard), grain size of sediments, sediment thickness determined by divers, acoustic profiling of the seabed morphology.
This is the first map of reefs in Bulgarian Black Sea drawn based on expert interpretation of the following data: point data on the type of substrate (sediments, hard), rock samples, sediment thickness over bedrock determined by divers, acoustic profiling of the seabed morphology.
Map of benthic biotopes in the sediments in part of Natura 2000 SAC Ropotamo, the Bulgarian Black Sea. The biotopes were defined based on the sediment type, depth range and the typical associated macrozoobenthos communities as differentiated by multivariate similarity analyses.
The Shabla complex includes the Shabla Lake and the Shabla Lagoon. The Shabla Lake is a firth brackish lake near the sea coast. The semi-saline Shabla Lagoon is located1.5 km to the southeast of the lake and is separated from the sea by high dunes.The territory of the Ramsar site is 404 ha, of which 150 ha of open water.The lake falls into the boundaries of the Natura 2000 protected sites “Shablenski ezeren komplex” (code BG0000156, according to theBirds Directive) and protected site “Ezero Shabla - Crapetz” (code BG0000621, according to theHabitats Directives).This location provides suitable habitats to 223 species fromthe Biodiversity Act, which are in need of special protectionmeasures.The following habitats according to Annex I to Directive 92/43EEC have been established: Marine - 1110 Sand Banks, which are slightly covered by sea water all the time; : 1150 Coastal lagoons; ; 2110 Embryonic shifting dunes; 2120 Pannonic dunes along the shoreline with Ammophila arenaria (white dunes)
