Salicetum auritae is an oligotrophic to mesotrophic type of willow carr, dominated by Salix aurita, S. cinerea, Frangula alnus, and on some sites in southern Bohemia also by Spiraea salicifolia. The herb layer includes species typical of acidic fens and moss layer is often dominated by species of Sphagnum. This vegetation occurs in fen complexes, near nutrient-poor ponds and on abandoned acidic wet meadows. Its distribution in the Czech Republic is poorly known.
