Nature and Man in the Park

Guide interattive alla flora del Parco e d'Italia

Dryades è la branca italiana del Progetto Europeo KeyToNature, coordinato dall'Università di Trieste e finanziato dalla Commissione Europea nell'ambito del Programma eContentplus.

Flora and vegetation

The Park’s flora and vegetation are greatly influenced by the large number of lakes and small wetlands in the area, as well as abundant outcrops of serpentinite, rocks that result in shallow soils poor in nutrients. In the upper valley of Dondena, in the municipality of Champorcher, extensive outcrops of calc-schist host a very rich and varied flora very different from that found on serpentinite.


A prime feature of the Park’s fauna is the high number of insect species present, due to the considerable environmental variety of the protected area. For example, up to now the following have been recorded:
- over 1100 species of butterflies, including 70% of all the macrolepidoptera known in the entire Valle d’Aosta and 4 species of microlepidoptera new to science;
- 22 species of Dytiscidae and Helophoridae beetles in the wetlands;
- 111 species of phytophagous beetles of the forest (32 of which have never been reported before in Valle d’Aosta).

Geo-morphological, mineralogical and hydrological aspects

The Park mainly has outcrops of the Piedmont calc-schist complex with greenstone (ophiolite of the ultrabasic rock complex of Mont Avic prevail in Val Chalamy; calc-schist prevail in Champorcher Valley). The ophiolites are a fragment of the Piedmont oceanic basin, involved in the alpine orogenesis following the continental collision between Africa and Europe.

“Natura 2000” environments

Mont Avic Natural Park has been included in the European Union ecological network “Natura 2000” which aims to guarantee the conservation of the habitats and species listed in the European Union’s Birds Directive 2009/147/EC and Habitats Directive 92/43/EEC. The protected area is classified as a Special Area of Conservation (SAC IT1202000) and Special Protection Area (SPA Mont Avic - Mont Emilius IT202020).
