Hungary names additional Tisza valley site for the Ramsar List


Simultaneously with Hungary's joint designation with the Slovak Republic of reaches of the upper Tisza River in a new transboundary Ramsar site, the Administrative Authority has also nominated for the List of Wetlands of International Importance another very interesting site farther downriver. Csongrád-Bokrosi Sós-tó (770 hectares, 46°42'N 020°01'E) is a Nature Reserve located in Bács-Kiskun and Csongrád counties, composed of two seasonal saline lakes, Nagy Sós-tó of 100 ha and Kis Sós-tó of 10 ha and including saline marshes, saline meadows, a mosaic of loess meadows on high embankments, and agricultural areas of different sizes in between the ponds. The site is home to rare, endemic and threatened communities and species including European otter Lutra lutra, Ferruginous Duck Aythya nyroca, Glossy Ibis Plegadis falcinellus, and Great Bustard Otis tarda. It is part of the migration route along the Tisza river valley and supports more than 20,000 waterfowl seasonally, playing an important role as a resting, feeding and breeding site. Waterbirds regularly using the site include Pintail, Shoveler, Teal, Wigeon, Mallard, Garganey, White-fronted Goose, Greylag Goose, Bean Goose and the globally threatened Lesser White-fronted Goose. Past measures in the catchment area decreased the extent of wetlands through lowering the groundwater table. A potential threat to the site is the acceleration of the eutrophication process caused by nutrients coming from the arable lands. Ramsar site no. 1409.

Hungary presently has 23 Wetlands of International Importance, covering a surface area of 177,228 hectares.
