Southern Alpine oatgrass-blue moorgrass swards

Xero-thermophile, open, stepped or garland, species-rich grasslands of the alpine and subalpine levels of the southern Alps, and particularly of the southwestern Alps, similar to those of the previous unit (36.431), but in which [Carex sempervirens] is less prominent, while various oats, [Helictotrichon sedenense] ([Avena sedenensis]) ([Helictotrichon montanum], [Avena montana]), [Helictotrichon sempervirens], [Helictotrichon parlatorei], [Helictotrichon setaceum], or [Festuca dimorpha] become important components together with [Sesleria albicans], and oro-Mediterranean species such as [Globularia nana], [Hedysarum hedysaroides], [Lilium pomponium], [Centaurea triumfetti], [Ononis cristata] ([Ononis cenisia]), [Ononis striata], [Iberis sempervirens], [Aethionema ovalifolium], [Sempervivum calcareum], [Arenaria cinerea], [Alsine brunati], [Galeopsis reuteri], [Leuzea rhapontica ssp. bicknellii] ([Leuzea rhapontica], [Rhaponticum scariosum]) and the spiny [Astragalus sempervirens] appear; several of these species are local endemics of very restricted distribution.
