Two territories in the province of Salamanca, the Sierras de Bejar and Francia and the Arribes del Duero Natural Park, have been declared UNESCO Biosphere Reserves, due to their environmental quality and sustainable development.
The Sierra de Bejar and Francia cover an area of around 200.000 hectares, so from 2006 it is the largest Reserve of the region and the third one in Spain. In these Reserves, we can visit Las Batuecas-Sierra de Francia Natural Park and the Natural Areas of Las Quilamas and Candelario.
They are made up by 88 villages and towns in the south of the province and the rich biodiversity includes more than 2.000 vegetal species, 5.000 invertebrate species and more than 300 vertebrate ones.
