Nature in Bulgaria has so much to offer you! Besides the impressive Cape Kaliakra Reserve and the plant-rich Strandzha Nature Park, you should definitely keep the Srebarna Biosphere Reserve in mind.

Srebarna Biosphere Reserve: An Overview

The biosphere reserve is located 2 km from the Danube and thus near the town of Silistra in northeastern Bulgaria. In total, the reserve covers an incredible area of 600 hectares of core zone and 500 hectares of buffer zone (in case of harmful influences). Due to its uniqueness, the Srebarna Biosphere Reserve was included in the World Network of Biosphere Reserves in 1977 and declared a UNESCO World Natural Heritage Site in 1983. Generally speaking, it is a reserve consisting of a freshwater lake with an adjacent marshland, floodplain forest, wet meadows and reed zones.

A Sanctuary for Birds

The reserve is known for its crucial protective role for birds as Europe's most important bird sanctuary. It is home to around 80 migratory bird species that overwinter in the reserve, as well as a further 99 bird species that use the biosphere reserve near the Danube during their breeding season. In total, you can discover 233 bird species in the protected area, whose presence may vary depending on the season.

Particularly well-known species include the Dalmatian pelican, the cormorant, the ferruginous duck, the red-breasted goose, the black-crowned night heron and the little bittern. The Dalmatian pelican makes up a full 10% of the world population within the biosphere reserve and is considered the largest bird of its kind in Europe. Protecting this species is all the more important, as it is now only known as a rare occurrence and suffers from the destruction of floodplain areas (such as in Germany, for example). Generally, however, the Dalmatian pelican breeds from Mongolia all the way to southern Europe, occasionally also crossing countries such as Hungary (albeit very rarely).

Equally important is the ferruginous duck, which is listed in Germany on the Red List of endangered breeding bird species and is threatened with extinction. In addition, the red-breasted goose has been classified as endangered. It is therefore clear that the Srebarna Biosphere Reserve makes a decisive contribution to the protection of bird species. For this reason, Lake Srebarna (as part of the reserve) was already declared a bird sanctuary in 1942. The site subsequently gained the status of a nature reserve in 1948, before later being declared a UNESCO World Natural Heritage Site.

The Srebarna Biosphere Reserve offers its inhabitants a diverse habitat. This includes open waters covering an area of 120 ha and reed zones covering an area of 400 ha. The reserve is also home to interesting plants that adorn the area and create a natural atmosphere. In the area, you will find poplar stands, grass and wet meadows, marshland as well as underwater vegetation, water lilies and willow species.

Visiting the Reserve: What Should You Keep in Mind?

Rules of Conduct

Various rules must be observed in the biosphere reserve in order to treat nature with respect and not endanger the protected area. For one thing, hunting and fishing are strictly prohibited. Likewise, you cannot simply wander freely through the protected area. Please use, for example, the ecological nature trail, which will take you to various observation towers. From there, you can also wonderfully pursue your passion for bird watching. Depending on the season, it is also possible to take part in a boat trip. If you would like to learn more about the reserve and its inhabitants, you can also visit the Natural History Museum. This welcomes around 15,000 interested visitors each year.

When Is the Best Time to Visit?

A visit to the biosphere reserve is free of charge, although donations are always welcome. The best time of year to visit varies depending on the individual visitor's goal. While the breeding season takes place from May to July, during which you can encounter a great variety of species, migratory birds roam the country from August to October. Only the best time of day does not vary! If you would like to observe the animals extensively, you should visit the reserve in the early morning or in the evening.
