that may occur there attempts to assure its protection. Natural parks focus their attention on the conservation and maintenance of flora, fauna, and terrain. Natural parks may be maritime or terrestrial and can be in the mountains, along the coasts, in the desert, or any other geographically defined space. Spain distinguishes natural parks from national parks. The categories of protected areas in Spain under Law 4/1989 are not based on higher or lower levels of protection, but on functions and characteristics: Parks: "natural areas, little transformed by human exploitation and occupation, that, for reason of the beauty of their landscapes, the representativeness of their ecosystems or their flora, fauna or geomorphological formations, possesses ecological, aesthetic, educational and scientific value, whose conservation merits preferential attention. A National Park is so designated because it is of national interest by reason of being representative of the natural heritage and that it includes some of the principal natural systems of Spain." Nature reserves: "natural spaces whose creation has as its end the protection of ecosystems, communities or biological elements that, because of their rarity, fragility, importance or singularity merit a special valuation." Natural monuments: "natural spaces or elements constituted basically by formations of notably singularity, rarity or beauty, that merit being the object of special protection." Protected Landscapes: "concrete places in the natural environment that, because of their aesthetic and cultural valuer, merit special protection." The largest protected space in Spain, and also its largest natural park, is the Sierras de Cazorla, Segura y Las Villas Natural Park in the province of Jaén, at the headwaters of the Guadalquivir. 9.1 percent of the surface area of Spain is protected, including 42 percent of the Canary Islands, 30.5 percent of Andalusia, and 21.51 percent of Catalonia, with lesser percentages in the other autonomous communities. Andalusia, being far larger than the Canary Islands or Catalonia, has 36 percent of the total protected areas in the country.
