This paper presents the characteristics and utility assessment of grasslands in the certified organic farms breeding herbivores livestock, located in the Sudety Mountains. Based on the analysis of the floristic composition, four types of floristic vegetation with dominant species in the sward were identified. Among them, 75% was represented by the most common types with the dominance of Agrostis capilaris L. or Festuca rubra L. s. str. The type containing high value forage grasses covers approximately 21% of the area. Meadows and pastures are diverse both, in terms of vegetation structure (utility group) and utility value – fodder value score (FVS). Grasses have the largest share in the coverage area – up to 70%, with the most prevalent groups being herbs and weeds. An important component of the sward is Fabaceae - least numerous group, however covering a relatively broad area, between 10% and 20%. Most of the examined grassland (over 61%) has a good and very good utility value (FVS > 6.0). Most valuable grasslands (FVS from 7.5 to 8.2) are located below 500 m a.s.l., whereas those of low value - more than 700 m a.s.l.
