The aim of this study was to determine floristic diversity, the chemical composition, nature value and energy value of selected sedge communities in view of habitat conditions in the Noteć valley. This study was based on a total of 46 relevés prepared according to Braun-Blanquet. The identified communities were represented by common plant associations, both natural or semi-natural. They comprised mainly vegetation of meadows excluded from agricultural use, on fresh and partly moist and very moist soils, of weak acid and neutral reaction. Analysed communities had moderate or high nature value. Sedges and Cyperaceae predominated in their structure, with the greatest share of Caricetum lasiocarpae (76%) and the lowest share of Caricetum distichae (44.6%). No Fabaceae were reported in any of the two plant associations, while herds were found in all associations. The greatest higher heating value and lower heating value were found for communities with Carex lasiocarpa and Carex disticha.

The paper presents the characteristics of Sudeten grasslands (species composition, floral diversity and habitat parameters) from the perspective of diversified management. On the sites examined, hay meadows were found with Arrhenatheretum elatioris, variant with Trisetum flavescens and pastures of Lolio-Cynosuretum. Mowing and grazing promoted floristic diversity. There were few grass species. On the sites examined, the share of tall grasses (Arrhenatherum elatius, Dactylis glomerata, Alopecurus pratensis) was high. There were many species of dicotyledons (including leguminous plants). The pasture was characterized by a larger quantity of total grasses, with a larger share of low grasses (Cynosurus cristatus, Trisetum flavescens, Festuca rubra and Agrostis capillaris) along with grazing species (Trifolium repens, Alchemilla monticola, Carum carvi and Leontodon autumnalis). Both meadow and pasture were dominated by ground-level budding plants (hemicryptophytes) with a share of about 80%. Differences occurred in remaining life forms: the meadows contained larger quantities of one-year plants (terophytes). Dominating in both cases were species of plants preferring moderate light (76 to 79%). However, meadows contained more species requiring full light, and pastures contained more numerous species growing in partial shade. Pastures contained slightly more species with high water requirements. These species grew mainly in moist areas. Meadows had a greater share of mesotrophic species, pastures had a greater share of eutrophic species.
