Mine in Florinas (SS)

Section of San Lorenzo: at the top,

This is a big mine, which includes an old abandoned mine site that Gruppo Minerali Maffei has reused in part. The past activity has left a heavy legacy with regard to restoration: a precipice wall, called Massacci. This has eroded a lot over time and has been experienced several collapses, so for security reasons we had to take away the area subject to landslides, but at the same time making the slope even more pronounced. This has not helped in the recovery.
Now the wall has been partially hydroseeded and partly revived with the pockets system, which involves creating niches in the rock, filling them with soil and planting a casmofita tree, that is suited to life on the cliff wall. In the rest of the Florinas mine, where we could operate normally, we created terraces that allowed the recovery of quality, made with native Sardinian shrubs and wild seeds collected by hand. The use of genetic material of the island has allowed us not to pollute the endemic biodiversity and at the same time obtain the best rooting results. Environments useful to birdlife, including a large pond, have been recreated and have allowed the census of 78 different species in 2009-2010 (Bordignon and Grussu 2011, in progress), including rare species in the Birds Directive such as the Peregrine falcon (Falco peregrinus), the Shrike (Lanius collurio), the Nightjar (Caprimulgus europaeus), the Stone Curlew (Burhinus oedicnemus), the Woodlark (Lullula arborea), the marmora's Warbler (Sylvia sarda) and the Dartford Warbler (Sylvia undata). The results are encouraging.

Freshly dug sand is loaded onto the truck.    Specialized operators insert the seedlings of rupicole species in the pockets of the rock (2010).

Two pockets in the rock, created specifically to house plants adapted life on the cliff wall: in the left pocket an Inula viscose, in the right, a Spartium junceum.

A truck loaded with seedlings to be planted on the Massacci wall (2010).

A part of the restorations in Florinas has been 'furnished' to accommodate visitors.    Nesting boxes are used by cave-dwelling bird species, such as titmice, which would otherwise not be able to nest, given the young age of the plants introduced by the restoration.
