| General Description | The Dehesas de Sierra Morena was declared a biosphere reserve in 2002, following a proposal made by the Regional Environment Council and the Andalucía Committee. The Dehesas de Sierra Morena embraces the Aracena and Picos de Aroche Nature Park in Huelva, the Sierra Norte in Seville, and the Sierra de Hornachuelos in Córdoba. The biosphere reserve integrates 43 municipalities in three provinces, with a total population of more than 90,000 (2002). The area is recognized for its important cultural heritage, and has large expansive areas of holm and cork oaks, surrounded by pasture, meadows and Mediterranean scrub. The dehesas are an agrosilvopastoral system that has enhanced the maintenance of an extraordinarily high biodiversity. The traditional use is characterized by mixed livestock raising at low stocking densities, employment of hardy regional breeds and an elaborated maintenance and exploitation of holm oaks. Livestock production has traditionally been accompanied by arable systems with long rotations and closed nutrient cycles without external inputs of fodder, fertilizers and agro-chemicals. Modern trends are a specialization toward lamb and beef production and the employment of intensive techniques like free range grazing at high stocking levels or crossbreeding with high-performance breeds. The biosphere reserve expresses the significance of the dehesas for biological conservation and the socioeconomical reality of its use in a multidisciplinary manner. | |||
