Vertebrates

Animals presenting, as a distinctive and peculiar feature, a spine that gives support to the body and allows it to move. The vertebrates represent approximately just 2% of all animal life on Earth. They are present in Italy with about 1300 species, accounting for 1 to 2% of the entire Italian fauna. In Aosta Valley about 350 species are present.

Invertebrates

Large and heterogeneous set of animal species without an internal skeleton. They represent about 97% of all animal life forms on Earth. First to colonize our planet, about 4 billion years ago, they populate any terrestrial environment. In Italy there are about 55100 species, accounting for 98-99% of the Italian fauna

Protection

The conservation of wildlife must consider multiple biological characteristics of vertebrates and invertebrates species, including high mobility and interactions among even distant populations. More and more often the legislative protection interventions must be transnational and thus they are shared by several Countries and Regions.

Vascular flora

It represents the set of all those plants equipped with a specialized vascular system for the transport of water, minerals and sugars. Are part of the vascular flora the pteridophytes and phanerogams, all plants equipped with seeds and flowers more or less specialized, which represent, by themselves, about half of all species of the vegetable kingdom.

Protection

With the Regional Law No 45/2009 - Regulations for the protection and preservation of alpine flora, the Autonomous Region of Aosta Valley regulates the protection and conservation of spontaneous and native alpine flora, as well as some species of ferns, mosses and lichens. Through habitat protection, promotion of conservation and management programs, research and promotion activities, this law is intended to ensure, on the basis of international, community and national laws, the proper conservation of the flora heritage.

Open

Lichens

Symbiotic organisms resulting from the close association between a fungus and an algae. The fungus absorbs the nourishment from the algae, and in return it provides water, minerals and support. Thanks to this symbiosis the lichen can live in extreme environments, generally inaccessible to other forms of plant life.

Protection

With the Regional Law No 45/2009 - Regulations for the protection and preservation of alpine flora, the Autonomous Region of Aosta Valley regulates the protection and conservation of the species of lichens, which reproduction and diffusion occur in natural way. Through habitat protection, promotion of conservation and management programs, research and promotion activities, this law is intended to ensure, on the basis of international, community and national laws, the proper conservation of the natural heritage.

Open

Bryophytes

Very primitive plants that have structures similar to leaves and stems, but they are not provided of real roots and vascular tissues, and for this reason they are small. They are generally pioneer plants, able to colonize inhospitable places, where they retain water and limit soil erosion, thus favoring the settlement of species with more ecological requirements.

Protection

With the Regional Law No 45/2009 - Regulations for the protection and preservation of alpine flora, the Autonomous Region of Aosta Valley regulates the protection and conservation of the species of mosses whose reproduction and distribution occur in a natural way. Through habitat protection, promotion of conservation and management programs, research and promotion activities, this law is intended to ensure, on the basis of international, community and national laws, the proper conservation of the natural heritage.

Mushrooms

Systematic heterogeneous group, which includes organisms with very different shapes and sizes. In general, being unable to perform the photosynthetic process, unlike the plant they must draw nourishment from other organisms. They can be parasites of animals or plants or they can live on dead organic matter, accelerating its processes of decomposition.

Herbage
Heterogeneous group of plants without woody stem. Depending on whether the underground part of the plant is persistent or not, they can be annual, biennial or perennial. The survival of herbaceous plants is ensured by a type of sexual reproduction through seeds or durable underground structures that allow a vegetative-type reproduction.
Open

Pteridophyta
Plants without flowers and seeds that reproduce by spores and have a development cycle that is completed by alternating two generations, only one of which has reproductive function. They are already evolved plants, as consisting of stem, leaves and roots and are equipped with a vascular system for the transport of fluids.
Open

Schrubs
Perennials plants characterized by a persistent woody stem surviving throughout the year, already branched as out of the ground . The shrubs generally not exceed 5 meters in height.
Open

Trees
Long-living perennials plants, characterized by a woody stem undivided at the base that branches since a few meters from the ground to form, together with the leaves, the characteristics foliage in shape and color. Depending on whether the leaves are persistent or deciduous, are divided into broadleaf and evergreen.
