is an open woodland found at lower elevations, and dominated by species of Terminalia, Commiphora, Boswellia, and Acacia. Weyna dega is a woodland found in moister and higher locations, dominated by the conifers Afrocarpus gracilior and Juniperus procera. The lower portion of the Harenna Forest is a distinct woodland community, with an open canopy of Warburgia ugandensis, Croton macrostachyus, and Syzygium guineense, and Afrocarpus gracilior, with wild coffee (Coffea arabica) as the dominant understory shrub. The southwesterly winds bring rainfall from May to October with moisture from the Red Sea coming in from the east year round. Fauna at these elevations includes the endemic Harwood's spurfowl (Pternistis harwoodi), Prince Ruspoli's turaco (Tauraco ruspolii) and yellow-throated seedeater (Serinus flavigula) The Ethiopian montane grasslands and woodlands is the largest of the highland ecoregions, occupying the area between 1,800 and 3,000 meters elevation. The natural vegetation was closed-canopy forest in moister areas, and grassland, bushland, and thicket in drier areas. However these hillsides have good fertile soil and are heavily populated, largely by farming communities, so most of the region has been converted to agriculture with a few areas of natural vegetation remaining. Urban areas in this ecoregion include: Ethiopia's capital city and Africa's fourth largest city Addis Ababa, the Amhara Region capital Bahir Dar with its island monasteries on Lake Tana, the old walled city of Harar, the spa town of Ambo, Asella in the Arsi Zone, the trekking center of Dodola, the lakeside Bishoftu, the largest city in the southwest Jimma, the market town of Nekemte, and the capital of the Tigray Region, Mek'ele. Awash National Park is a site for birdwatching. Remaining woodland in the drier areas contains much endemic flora and primarily consists of the conifers Afrocarpus falcatus and Juniperus procera, often with the broadleaved Hagenia abyssinica. In the Harenna Forest, pockets of moist, closed-canopy forest with Pouteria and Olea are draped with lianas and epiphytes, while above 2400 meters, a shrubby zone is home to Hagenia, Schefflera, and giant lobelias (Lobelia gibberroa), species which can be found on the East African mountains further south. The evergreen broadleaved forest of the Semien Mountains, between 2,300 and 2,700 meters elevation, is dominated by Syzygium guineense, Juniperus procera, and Olea africana. 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.
