Site description The site is Europe's largest complex of natural floodplain fen mires. The significant size of the area contributes to the relative stability of its ecosystems, which, to a large degree, are independent of outside impacts.
Key Biodiversity Sporovo fen mire is a key habitat for the globally threatened Aquatic Warbler Acrocephalus paludicola, supporting 9% of the global population. It supports 20 more bird species listed in the National Red Data Book, including two disappearing ones, Corncrake Crex crex and Great Snipe Gallinago media, as well as an internationally important population of Bittern Botaurus stellaris and nationally important breeding populations of Black Stork Ciconia nigra. The site hosts a total of 123 bird species.
Non-bird biodiversity: The floodplain of the Yaselda river has a unique but not very diverse flora. High flora diversity is only observed on mineral islands; these, however, are few and in most cases transformed by people. 18 protected and 13 regionally important plant species occur. One of the unique Atlantic communities, Corynephoretum canescentis, is found here.Rare Red Data Book fauna includes one reptile species (Fresh-water Turtle Emys orbicularis) and 18 insect species (two of which are listed in the European Red Data Book).

Protection status National Conservation Status: A national biological zakaznik "Sporovski" in its contemporary borders was established in 1999. International Conservation Status: An IBA was established in 1998 (code BY 002-003, criteria A1, Â2, Â3).Sporovo is the first Ramsar site for Belarus, established in 1999 (criteria 1, 2).
