Phytosociological and habitat studies of rush communities were conducted in the Noteć Bystra and Noteć Leniwa river valley in the years 2010–2014. These communities are of varied nature value and form valuable ecosystems of high landscape value. Their development, floristic diversity, nature and agricultural value are connected primarily with their moisture content, resulting from the habitat mosaic and land use intensity. The calculated floristic diversity index (H’) ranged from 1.2 to 2.7, while valuation results provided by the method proposed by Oświt showed that communities with moderately high and high nature value predominate in the area. Most examined communities are of poor and mediocre economic and utility value, as evidenced by the calculated fodder value score FVS=1.7–4.1.
