the wild boar (Sus scrofa), on the other hand, have been well preserved because they are popular with hunters. More abundant and in varied situations of conservation are such smaller carnivores as otters, dogs, foxes, the European badger (Meles meles), the European polecat (Mustela putorius), the least weasel (Mustela nivalis), the European wildcat (Felis silvestris), the common genet (Genetta genetta), and the Egyptian mongoose (Herpestes ichneumon). Other notable species are Acherontia atropos (a variety of death's-head hawkmoth), Vipera latasti (a venomous snake), and the endemic (and endangered) fish Aphanius baeticus. Protected areas Andalusia has many unique ecosystems. In order to preserve these areas in a manner compatible with both conservation and economic exploitation, many of the most representative ecosystems have been given protected status. The various levels of protection are encompassed within the Network of Protected Natural Spaces of Andalusia (Red de Espacios Naturales Protegidos de Andalucía, RENPA) which integrates all protected natural spaces located in Andalusia, whether they are protected at the level of the local community, the autonomous community of Andalusia, the Spanish state, or by international conventions. RENPA consists of 150 protected spaces, consisting of two national parks, 24 natural parks, 21 periurban parks (on the fringes of cities or towns), 32 natural sites, two protected countrysides, 37 natural monuments, 28 nature reserves, and four concerted nature reserves (in which a government agency coordinates with the owner of the property for its management), all part of the European Union's Natura 2000 network. Under the international ambit are the nine Biosphere Reserves, 20 Ramsar wetland sites, four Specially Protected Areas of Mediterranean Importance and two UNESCO Geoparks. In total, nearly 20 percent of the territory of Andalusia lies in one of these protected areas, which constitute roughly 30 percent of the protected territory of Spain. Among these many spaces, some of the most notable are the Sierras de Cazorla, Segura y Las Villas Natural Park, Spain's largest natural park and the second largest in Europe, the Sierra Nevada National Park, Doñana National Park and Natural Park, the Tabernas Desert, and the Cabo de Gata-Níjar Natural Park, the largest terrestrial-maritime reserve in the European Western Mediterranean Sea. History The geostrategic position of Andalusia in the extreme south of Europe, providing (along with Morocco) a gateway between Europe and Africa, added to its position between the Atlantic Ocean and the Mediterranean Sea, as well as its rich deposits of minerals
