D4.1N1 - Niveau 5 : Tourbières de sources calcaires médio-européennes
Description
Communities of calcareous springs, seeps and flushes of the nemoral and lowland boreal western Palaearctic domaine in which tufa formation is absent or limited to encrustation of the constituting mosses without building of large deposits. They are characteristic of high altitudes, maritime climates and semishaded stations, all situations unfavourable to tufa formation.
