Site description (2000 baseline):
Site location and context
The site contains the Tyœmienica river valley (right-bank tributary of the Wieprz river) and is covered by wet meadows with some remnant sedge-beds and scrub of willow
Salix and alder
Alnus that are used for agriculture. There are eleven small pond complexes, a few hundred peat pits, oxbow lakes, and the large Siemieñ pond complex (790 ha). In that complex 20% of large ponds and 40-50% of small ones are overgrown with reed
Phragmites and reed-mace
Typha. The site is surrounded by agricultural land.
Breeding species of global conservation concern that do not meet IBA criteria:
Gallinago media (up to five pairs).
Pressure/threats to key biodiversity
Fishermen, and reed burning in spring, cause some disturbance to birds, especially to geese and some ducks. Also, early filling of some ponds reduces breeding numbers of
Charadrius dubius and
C. hiaticula, and filling ponds too high destroys nests of gulls and terns.
National None
International None
