Flora
Alpine regions have a high rate of endemism and a high diversity of plant species. This taxonomic diversity can be attributed to geographical isolation, glaciation, microhabitat differentiation.
Galium montis-arerae, the Pizzo Arera bedstraw, is a rare plant species in the Rubiaceae. It is named after the mountain, locus classicus where it was first described.
