PLOT 3: a scree at about 2500m a.s.l.
We take the trace of an old path and after a few steps we meet a spring. Among the rocky crags of an arid and karstic Brenta, it seems almost a mirage to see water flowing freely on the surface, without disappearing immediately swallowed by the mountain. We continue a little further, our goal is the third plot at an altitude of 2500 m.
Although of limited dimensions, the spring represents a hot spot of biodiversity, an ecological refuge for many animal and plant species characteristic of the hypogean and epigean environment. We were able to recognize the planarians, flatworms with considerable regenerative capacity and several insect larvae. Among these were also Chironomids, that are the subject of a specific study thanks to the collaboration of the Section of Invertebrate Zoology and Hydrobiology of MUSE.
On the Brenta Dolomites, at high altitude, places like this are out of the ordinary. In August, all around the Gentiana brentae bloom, an intense blue color, endemic to the Brenta Dolomites. There is only one tiny presence in the near Adamello.
During the ascent to the plot, the singing of the Apine accentors pleasantly interrupts the morning silence …
Within the Plot there are two habitats that have become part of the ““Natura network 2000 ” due to their value and to their scarce distribution on a community level. A network of areas recognized by the European Union as strategic for biodiversity conservation at a supra-national level.
- 8120: Mountain and alpine calcareous and schist screes
- 8210: Calcareous rocky walls with chasmophytic vegetation
