Trisetetum flavescentis (Schröter) Brockmann 1907

Trisetum flavescens-golden oatgrass meadows occupy the slightly sloping hills, in the following localities: Archita, Fi§er and Beia, at altitudes between 480-630 m. The flora of the association is diverse, consisting of 101 cormophytic species, of which most (54.45%) belong to coenotaxa characteristic to this class (Table 7). Trisetum flavescens phytocoenoses are tiered, in the upper level, besides edifying species, vegetate: Agrostis capillaris, Arrhenatherium elatius, Cynosurus cristatus, Festuca pratensis, Knautia arvensis, Leucanthemum vulgare etc., and the second level is composed of: Carum carvi, Lotus corniculatus, Cerastium holosteoides, Trifolium pratense etc. Other important species have been described: Achillea millefolium, Onobrychis viciifolia, Daucus carota, Holcus lanatus, Dianthus carthusianorum etc.

Conservation value of pastures is reduced.

Forage value of golden oatgrass meadows is good, with high productivity.
