Sardinia is one of the least populated regions in Italy; it counts only 1.659.300 inhabitants and has one of the lowest population density as well (only 69 inhabitants per km², versus a national average of 190 inhabitants per km²).
From the morphologic point of view this region is quite particular; despite the fact it doesn't have significantly high mountains (with the only exception of La Marmora peack in the massif of Gennargentu of 1834 mt. and of the mount Limbara of 1362 mt.), more than 80% of its surface is hilly or mountainous. Also from the hydrographic point of view it is quite particular; absence of glaciers, nature of soil mostly made of waterproof rocks and concentration of rain in only two months make nature of rivers mainly as torrent water.
In Sardinia historical and social reasons and maybe peculiarity of territory too, caused population concentrated in few agglomerates instead of occupying territory in a spread way. For these reasons a large part of territory remained almost intact and this favoured preservation of animal species some of them quite rare (on the contrary some other species like for instance bears, vipers and marmots absolutely absent on the island). The reach vegetation, mainly scrub, unfortunately is tried sorely by the calamity of arsons (and animals as well as vegetation); in fact in Sardinia there is more than 50% of the woodlands that every year goes up in smoke due to arsons.
