Site description (baseline)
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.
