Scheiden-Wollgras
The Plateau de Beille is a Zone naturelle d'intérêt écologique, faunistique et floristique [Natural Zone of Ecological Interest, Fauna and Flora] (ZNIEFF) type I. Its habitat consists of short lawns, forests of "Pinus uncinata" at altitude, a beech-fir forest on its lower slopes, moorland and some bogs. In the bogs are oblong-leaved sundew ("Drosera intermedia"), round-leaved sundew ("Drosera rotundifolia") and bog club moss ("Lycopodiella inundata"), rare and protected species, but also the marsh cinquefoil ("Comarum palustre") and tussock cottongrass ("Eriophorum vaginatum").
