Alliance TDB
Polygono bistortae-Trisetion flavescentis Br.-Bl. et Tüxen ex Marschall 1947

The alliance Polygono-Trisetion includes mesic montane meadows on nutrient-rich soils. These are usually dominated by medium-tall grasses. In addition to species typical of meadows they also contain some species of forests and subalpine tall-forb vegetation. Due to the less favourable montane climate, Polygono-Trisetion meadows are less productive than those of the alliance Arrhenatherion elatioris. Therefore they are less intensively managed, being mown once or twice a year. These meadows occur in various mountain ranges of temperate Europe, becoming progressively more common in oceanic areas.
