Protected Landscape of the Mining Basins Nature · Mieres, Caudal, Asturias Image of Mieres, not of the place itself. An inland range of 13,225 hectares declared by decree of 14 March 2002, spread across Mieres, Langreo, Laviana and San Martín del Rey Aurelio; it protects mountains and forests on carboniferous bedrock at the headwaters of the Caudal and Nalón valleys, with Peña Mea (1,559 m) as its most distinctive peak. The vegetation combines meadows and farmland with oak, beech and Pyrenean oak woods, and shelters the Cantabrian capercaillie, the Egyptian vulture, the otter and the Pyrenean desman, as well as wild boar and roe deer; the mountain is recovering from old mining activity and acts as a wildlife corridor towards the Redes natural park. Sheep, cattle and horse farming continues, in decline, and numerous routes link up with the industrial heritage paths of the lower valleys.
