The Biosphere Reserve of La Rioja is a large area that occupies almost a quarter of the southeastern part of the region. It has a geographical, climatic and landscape homogeneity that gives it a very high environmental value. The Leza, Jubera, Cidacos and Alhama Valleys were listed as a World Biosphere Reserve by UNESCO on 9 July 2003.
