The Muniellos nature reserve protects a wooded area in Asturias, Spain. The area of the nature reserve is 5,488 ha. The main species of tree is oak. In the 1970s timber extraction was forbidden and the woods were preserved as a hunting reserve. Hunting has since also been banned, and human access is now strictly controlled.
Wildlife includes brown bears (Cantabrian brown bear) and capercaillies (Cantabrian capercaillie). There is also a population of the rare Kerry slug.[1]
In 2000 UNESCO designated Muniellos as a biosphere reserve. The area of the biosphere reserve was extended in 2003 to take account of the creation of the Natural Park of Fuentes del Narcea, Degaña e Ibias, which incorporates Muniellos. The core area of the Muniellos biosphere reserve occupies 8,661 ha, making it somewhat larger than the nature reserve. The rest of the natural park is classed as a buffer zone to the core area.
As at 2011 there has been discussion of how the various biosphere reserves in the Cantabrian Mountains could be managed as a single super-reserve to be known as Gran Cantábrica.[2] The other relevant reserves include Somiedo Natural Park and Redes Natural Park, which are also in Asturias.[3] The proposed integration is expected to benefit endangered wildlife such as the Cantabrian brown bear and Cantabrian Capercaillie, by reversing habitat fragmentation. There are recovery plans in operation for both of these animals as they need to extend their range within the Cantabrian mountains in order to build sustainable populations.[4][5]
Bosque de Muniellos (Spanish for "Muniellos Wood") is a Special Protection Area for bird-life under the European Union's Birds Directive.[6]
