37.215 - Bistort meadows

Classification des habitats du Paléarctique (2001)

Description

Wet and humid meadows of sub-Atlantic Western and Central Europe dominated by, or very rich in, Polygonum bistorta, most characteristic of montane or submontane regions of the Hercynian ranges and neighbouring regions. They include distinctive acidocline Hercynian communities in which Polygonum bistorta is associated with Deschampsia cespitosa or Juncus filiformis, Polygonum bistorta-enriched submontane or montane variants of thistle or ragwort lowland communities of units 37.211 or 37.214, of the montane thistle-globeflower communities of unit 37.212, of the clubrush communities of unit 37.219, peri-Hercynian submontane and lowland thermophilous communities of the Danube basin, and montane communities of the Iberian peninsula. They constitute the principal habitat of the threatened fritillary Proclossiana eunomia, and, at least locally, an important habitat for other threatened butterflies, in particular, the copper Palaeochrysophanus (Lycaena) hippothoe.
