      Biosphere Reserve Information



  General Description   Grazalema is located in the southwestern part of Sevilla, in the hydrographic complex of Cádiz. It is also situated in the extreme western side of the ‘Beticas’ mountain chains in the ‘Serranía de Grazalema’ comprising the Pinar, Zafalgar, Monte Prieto and Margarita’s mountains. It consists of a massif karstic limestone with closed river basins, headstreams of the Guadalete and Majacete’s Rivers and tributaries of the Guadiaro. It also comprises a mountain lagoon called ‘Laguna del Perezoso’. The relief is very complicated and abrupt, comprising very jagged crests and cavernous karstic plateau, with precipitous edges. The Sierra, the highest in the province of Cádiz, stands like a great spur overlooking the whole territory. The biosphere reserve contains a wealth of floral diversity, with some 700 species of vascular plants catalogued to date. Eighteen higher vegetation types have been found including evergreen sclerophyllous forests, woodlands and scrub. The core area comprises 300 hectares of Spanish fir (Abies pinsapo) forest, including carob tree woods, pine and fir woods. More than 8,000 inhabitants (2001) live in the biosphere reserve. In the low zones, cattle and sheep are allowed to graze with some restrictions. After nine years of protection, the Grazalema pine forest is rapidly evolving towards a state of equilibrium. An initiative to restock the karst-like deteriorated hills with standing shrubs and luxuriant creepers is being developed.
