The Site on the outskirts of the city of Burgas on the Black Sea coast features marshes, freshwater, brackish, saline and hyper-saline pools, and a shallow bay. It is one of the most important wetlands in Bulgaria for the variety of bird species: despite its relatively small area, 252 different species have been recorded. Several are internationally threatened, including the slender-billed curlew, white-headed duck, horned grebe, and the Dalmatian pelican which is present in internationally significant numbers. These species use the Site as a stopover during their migration and as breeding grounds. A significant threat is the natural expansion of reedbeds, which reduces the availability of open water and nesting grounds for some birds. As of 2019, the Site’s management plan was being updated.
