The flora of the Omaña and Luna valleys, which were designated Biosphere Reserve by UNESCO in 2005, includes many species which are endemic to the Iberian peninsula.

The region of the Omaña and Luna valleys is located in Castile and León, in the northwest of the province of León. It takes in the municipalities of Sena de Luna, Barrios de Luna, Soto y Amío, Murias de Paredes, Riello and Valdesamario. The region is surrounded by mountains which mark the frontier between the Cantabrian range and the León Mountains. In the La Cañada Mountains, in the southwest of the reserve, there are peaks in excess of 2,000 metres above sea level. Here you will also find the Luna and Omaña rivers, which give rise to a succession of fertile valleys and narrow gorges. As far as fauna is concerned, this area is the southernmost limit for animals such as the brown bear and capercaillie, currently endangered species in Spain.
