These unstocked forest areas are areas that have been deforested due to various disturbances, such as forestry and/or nonforestry operations, overgrazing, overexploitation for fuelwood and timber, repeated fires and attacks by insects and diseases (figure 13.1). These areas are expected to be regenerated. Non-forest areas (0.54 million ha) include areas within forest land, which include high mountain sub-alpine tundra vegetation, mountain slopes, rocky areas, meadows and tree nurseries. However, due to its small population (3.12 million people) and vast territory, and thus its low population density (2 inhabitants/km2, one of the lowest in the world), Mongolia is not designated a "low forest cover" country on the basis of its ratio of forested area per capita, which is 4.09 ha/capita (the global ratio is 0.54 ha/capita).
