Q41x Cantabrian neutro-basophilous fens

New search

Description

Calcareous and tufa-forming fens dominated by specialized small sedges and brown mosses. They are frequent in calcareous springs and the basins fed by them, but generally limited to small areas. The study area represents the SW distributional limit of the habitat in Europe, including relict species such as Salix hastata in Vega de Liordes (Picos de Europa). A regional level IV unit is created, since both the existence of some endemic plants and the geographic definitions of Q412 and Q413 preclude a seamless integration of our fens in any of them.
