The area of permanent pastures is the land overgrown with grass (for 5 years or more), which in principle is not mown but left for grazing. In mountainous regions it also includes the area of mountain pastures left for grazing and maintained in a good agricultural condition (including permanent pastures not used for production purposes and pastures for extensive grazing, located on mountainous land or at high attitudes with low-class soil, where no fertilisation, sub-sowing, melioration, etc. is performed).
