This site lies in the Province of Extremadura and is characterized by sclerophyllic Mediterranean forests and “Dehesas”, that is a landscape modelled by human impacts through cattle raising and production of cork from cork oak trees. The landscape of the biosphere reserve is very representative of Mediterranean agrosylvopastoralist system, with a very rich biodiversity although it has been strongly modified.


Declaration Date: 10 July 2003
Surface Area: 116,160 ha (core: 11per cent; buffer: 13 percent; transition: 76 per cent)
Administrative Division: 14 Municipalities have their territory in the Biosphere Reserve  

Human Activities

The main activities in the Biosphere Reserve are open range livestock-raising, environmental education, scientific research, cork harvesting and other forest uses, together with hunting and tourism.

Ecological Characteristics

The central area consists of a succession of sierras at an altitude of about 500 m, festooned by quartzite crests.

The best representations of Mediterranean forest and shrubland, harbouring 90 per cent of the Mediterranean flora present in the Iberian Peninsula, are to be found on the slopes of these sierras, particularly on the shady sides.

Towards the outer part and coinciding with the transition zone, less rugged and more accessible to humans, Dehesas take over from the Mediterranean forest.

They are in an excellent state of conservation, together with other less representative ecosystems such as the riparian woodlands, irrigated land near the Tietar River and the orchards andsmall holdings near the villages.

The presence of endangered species such as the Lynx and the Black Stork is noteworthy. However the most emblematic species in the Biosphere Reserve are the numerous and large colonies of birds of prey, such as the exceptional Spanish Imperial Eagle or Adalberti’s Eagle and the colonies of the Eurasian Black Vulture.
