Srebarna Lake Biosphere Reserve

Panorama

The Srebarna Lake was designated as a Monument of World Cultural and Natural Heritage (1983), UNESCO biosphere reserve (1977), Ramsar site (1975) and Important Bird Area (1990) because of its extremely rich ornithofauna and mainly because of the breeding of globally threatened species Dalmatian Pelican (Pelecanus crispus), Pygmy Cormorant (Phalacrocorax pygmeus) and Ferruginous Duck (Aythya nyroca). During the last years the lake ecosystem underwent significant changes towards strong eutrophication and anthropogenically speeded-up succession. The main reasons were the interrupted connection with the Danube River (because of a dyke built in 1948) together with the pumping-out of the underground waters, as well as the agricultural changes and activities in the watershed basin. The restoration activities carried out in 1993-1994 and especially the canal which connected the lake with the Danube lead to the beginning of lake recovery. All these events influenced the biodiversity of the reserve.

The dominant plant association is that of the Reed (Phragmites australis), which occupies about two-thirds (400 ha) of the Reserve's total surface area. Gray Willow (Salix cinerea) and Purple Willow (Salix purpurea) bushes grow in some places. The second widest spread plant species after the Reed is the Lesser Reedmace (Typha angustifolia), and it is more abundant than the Great Reedmace (Typha latifolia). Of all 139 vascular plant species hosted by the Reserve, 11 are rare or endangered. Some 19 fish species occurred in the lake until 1948. There are 21 reptile and amphibian species, and 41 mammal species. The avifauna numbered a total of 230 bird species. The nesting colony of Dalmatian Pelican (Pelecanus crispus) is the pearl of the Reserve.

Ecological station of CLGE-BAS

The permanent staff of the field station is involved in a routine long-term monitoring program of the reserve. The most frequently measured parameters are:

  • nutrients
  • phyto- and zooplankton composition
  • water level and temperature
  • quantitative estimations of bird populations

In the framework of short scientific visits researchers from the CLGE-BAS headquarters regularly collect samples to assess the trophic status, monitor fish and bird populations and assess the effect of anthropogenic impact.

Three recent PhD programs were completed using the facilities of this ecological station, two examining populations of diving ducks and habitat distribution of nesting populations in reedbeds and inundated forests, and one assessing the spatial distribution of small mammals.

Major applied project of CLGE-BAS based on this station were the elaboration of the management plan of the reserve (funded by Wetlands International) and the elaboration and implementation of the monitoring system in accordance with international obligations of the country as a member state of the Ramsar Convention (funded by the Ministry of Environment and Waters of the Republic of Bulgaria).

Another long-term project is the "Conservation actions for protection of Dalmatian Pelican (Pelicanus crispus)".

P.crispus Inthereserve

The Central Laboratory of General Ecology – Bulgarian Academy of Sciences (CLGE - BAS) dispose with Laboratory and Education Centre in Srebarna Village near the Srebarna Biosphere Reserve. In the Laboratory are performing the hydrobiological, microbiological and ornithological studies. The exhibition in the Education Centre has three aquariums, 2 terrariums and 23 posters, which present the history and biological diversity of the reserve.

The address of Laboratory and Education Centre is: 7587 Srebarna Village, Silistra District, 53 Dunav Street

The Field Station is in Srebarna Village (Silistra District). In the house there is 3 badrooms, two kitchens, two bathrooms and a storage place. Near the house there is also a garden with some fruit trees and vegetables.
