Geobotanical investigations were carried out in years 1994-1995 in the Bystrzyckie mountains which constitute part of the Middle Sudety Mountains. The total of 250 phytosociological records were taken using the Braun-Blanquet method in combination with site. The aim of the studies was geobotanical and economical evaluation of meadow communities occurring in that region. Results of investigations revealed that the meadow communities in the Bystrzyckie Mountains are dominated by grasses from Molinio-Arrhenatheretea class, i.e. Arrhenatheretum elatioris, Alopecuretum pratensis, Lolio-Cynosuretum, Trisetetum flavescentis and, as a rule, they demonstrate a higher economical value although in recent years their value has decreased. A characteristic features of these communities, in comparison with their counterparts occurring in lowlands, is their floristic richness, in particular, a big share of herbaceous plants. From among economically less valuable and low-value communities, the following deserve mention: communities from Deschampsia flexuosa from Elymus repens as well as bog-springs with Eriophorum angustifolium, while on dry slopes-communities from xerothermic grasses - Thymus serphyllum and Festuca ovina.
