As the lower slopes of the mountains are so heavily populated, even the high altitude moorlands are affected by human interference, such as the grazing of livestock and even farming. There are two protected areas of high moorland: Bale Mountains National Park in the southern highlands, accessible from Dinsho; and Simien Mountains National Park, accessible from Gondar, which includes Ras Dashen. However even these parks are losing habitat to livestock grazing, while the lower elevation parks (Harar Wildlife Sanctuary, Awash National Park, Omo National Park, and Nechisar National Park) are even less secure.
