Arsi Mountains National Park

Arsi Mountains National Park is a national park in Arsi Zone of Oromia Region in Ethiopia. It protects a portion of the Ethiopian Highlands, and includes montane forests, subalpine heath, and alpine grasslands and shrublands. The park was designated in 2011, and covers an area of 10876 km2.

Geography
The park encompasses the Arsi Mountains, which are part of the Ethiopian Highlands. The mountains extend northeast to southwest through the park, and form the southern wall of the African Rift Valley. Mountains in the park include Dhara Dilfekar block, Mount Chilalo (with the heigh of 4036 m), the Galama Ridges, Mount Kaka, and Hunkolo. The volcanic caldera of Mount Chilalo is the highest point in the park.

Mountain rainfall sustains numerous streams and alpine lakes such as Lake Ziway. The northern slopes drain towards the Awash River, while the southern slopes are drained by headwater streams of the Shebelle River.

Bale Mountains National Park lies southeast of the Arsi Mountains. The upper valley of the Shebelle River separates the Arsi Mountains from the Bale Mountains.

Flora and fauna
There are three main vegetation zones in the park, generally defined by altitude. Dry evergreen Afromontane forests predominate on the lower slopes, from 2843 to 3756 meters elevation. The dry evergreen forests are interspersed with areas of mixed plantations of native and exotic trees between 3181 and 3340 meters elevation.

Subalpine vegetation, mostly heath shrubland dominated by the shrubs Erica arborea and Erica trimera, occurs above the tree line, from 3202 to 3985 meters elevation.

Afro-alpine vegetation occurs at the highest elevations, from 3576 to 4008 meters. It is made up mostly of grasses, herbs, trees, and shrubs, including species of Helichrysum and Alchemilla, interspersed with stands of the giant lobelia Lobelia rhynchopetalum, which is endemic to the Afro-alpine Ethiopian Highlands.
