The study area “Altopiano delle Pale” was a karstic rock “desert” surrounded by several dolomite pinnacles, the one visible in this picture is the Rosetta Mount (2743 m a.s.l.) westward from the photographer. Behind it, to the right, the dark Lagorai mountain chain. The vegetation patchily colonised the study area exploiting the scarce presence of a thin lithosol. The “good” season usually lasts from the end of June to the beginning of September.
