Castro Verde Biosphere Reserve (Portugal)

Located in southern Portugal, in the hinterland of the Baixo Alentejo region, this biosphere reserve covers an area of almost 57,000 ha. It encompasses the most important cereal steppe area in Portugal, one of the most threatened rural landscapes in the Mediterranean region. It has a high degree of endemism in its flora. There is a bird community of around 200 species, including steppe birds such as the great bustard and endemic species such as the Iberian Imperial eagle, one of the most endangered birds of prey in the world. The population of about 7,200 habitants lives from the extensive production of cereals and livestock rearing.
