Lake Atanasovsko
Burgas
Lake Atanasovsko is a salt coastal lake located just north of Burgas, Bulgaria, adjacent to the Black Sea. Approximately 5 km long and divided by a central sand strip, it features diverse flora and fauna within its surrounding swamps and canals. Since 1906, the lake has been a site for sea salt production, yielding around 40,000 tons annually. Its northern part is a protected nature reserve established in 1980, connected to the sea by canals, while the southern section primarily supports salt extraction and acts as a buffer zone. The lake is a vital ecological habitat, home to over 230 vascular plant species including several endangered in Bulgaria, and hosts the smallest mammal by mass, the Etruscan pygmy shrew. It is one of Bulgaria’s key ornithological sites with 314 bird species observed, representing 70% of the country's avifauna. Notably, twelve globally endangered bird species such as the Dalmatian pelican and red-breasted goose inhabit the area. The lake lies on the important Via Pontica migration route, with peak bird populations during autumn. Since 2019, it hosts Bulgaria’s largest flamingo colony, though breeding has yet to be observed. The lake's ecological and cultural importance is further highlighted by the visitor trail dedicated to reed warblers and the salt production tradition that sustains its wetland habitats.

Histoire
Lake Atanasovsko has been used for salt production since 1906, leveraging its naturally high salinity linked to the Black Sea.
In 1980, the northern part of the lake was designated a nature reserve to protect its unique biodiversity.
The southern part was later classified as a buffer zone and then a protected area.
