Description

Sesleria albicans-dominated facies of communities of unit 34.322 or 34.326, often rich in dealpine species, occurring in particular in the Alpine and Pyrenean periphery, but also occurring locally, farther from the immediate Alpine influence, in anomalous stations such as steep, more or less shaded slopes or cliffs; Sesleria argentea-dominated grasslands of Alava and Navarra. Geographical subdivisions can be introduced by use of the fourth decimal digit of unit 34.322 in the fourth place of unit 34.325.
