Montiferru

It takes its name from the eponymous extinct volcano massif, whose main peak is the Monte Urtigu (1,050 m).

Extending for some 700 km2, the massif had originally a maximum elevation of c. 1,600/1,700 m, later reduced due to erosion.

Flora goes from the Mediterranean shrubland of the coast to olive and fruit trees in the mainland, up to pine and oaks in the more elevated parts.

Wildlife include wild boar, fox, Sardinian hare, European hedgehog, least weasel, marten, the rare Sardinian wildcat, vulture, carrion crow, peregrine falcon, hoopoe, little owl, Eurasian scops owl and others.

The rocks of Montiferru are the remains of an extinct volcanic complex, covering an area of about 400 square kilometres (154 sq mi), that was active 3.9 to 1.6 million years ago during the Pliocene and Pleistocene epochs of the Earth's geological history.
