Mine in Ottana (NU)

The mine is not visible from the street or from the town because it descends into a pit. What's visible instead is the mining waste, which forms two hills, which stick out in the middle of the countryside. Beside this is Fenudi, a small mine, also hidden.
Both this and the former are being restored. To date, 7.000 shrubs and plants have been inserted over 4 hectares.
The sides of two small hills, Carboni and Pittalis, are well grassed and defend the slope very well from erosion. However, the considerable permeability of the underlying soil, composed of stone, does not allow a luxuriant growth of shrubs and trees, so it has been decided to create a garrigue environment, mostly grassy and rather dry, with the aim of attracting steppe birds, whose community contains many species of high conservation value, which characterize the most precious fauna in Sardinia. In 2010, two important species have already been detected: the Rock Sparrow (Petronia petronia) and Stone Curlew (Burhinus oedicnemus), both protected species, contained in the Birds Directive. This is already an excellent result that bodes well for the arrival of other valued species.
In 2011, 1500 plants have been planted. To overcome the problem of drought, which occurred in the summer, and that would have surely caused serious losses, an irrigation program was put in place for the first time. The introduced species will provide edible berries for migratory birds.

The areas around the mine are rural in nature and pleasantly undulating.    A well-revived side of the Carboni field (2010).

A long slope where grass will be planted in Fenudi field (2010).    The top of the Carboni sector about to be covered with topsoil for the planned sowing (2011).

The buckthorn (Rhamnus alaternus) is a typical bush of the Mediterranean shrub-land, widely used in restorations.    The wildflowers that spontaneously appear on the restoration site increase biodiversity.

Cistus bushes (Cistus creticus) are among the first to spontaneously colonize the restoration site.

The jackdaw (Corvus monedula) is common in the vicinity of the mine.    Bordignon controlling the rooting of seedlings (2010).
