  Flora

  Green alder woods

  Settled above the altimetric strip occupied by the wood or interspersed with it at its upper limit of expansion, extend the alneti, the shrubby populations of green alder, which, especially on the cool and shady slopes, leave little room for other species woody. It is a nitrogen-fixing species which, thanks to the symbiosis with particular microorganisms, manages to capture the nitrogen present in the atmosphere both for its own survival and for the enrichment of the soil.

  History and historical trail

  Forte Giaura

  Forte Giaura is located on the homonymous Cima di Giaura. Armed with 8 pieces of artillery, it is still in excellent condition. On the attack front of the fort you can see the five splinter-guard partitions between the emplacements of the pieces in the open ("in barbetta").

  Fauna

  The ptarmigan

  The higher slopes facing north, covered with rocky debris, dwarf willows and a few grasses, are the preferred habitats of a rare glacial relict, such as the alpine ptarmigan. Its survival in a climatic phase like the current one is put at risk, its biology does not allow it to adapt so quickly to changing high-altitude environments. It will only survive on the cooler slopes of high mountains, as its ability to move is relatively small.
