Mankubsa–Welenso forest is near the Negele–Arero track between 20 and 40 km south of Negele town, the capital of Borana Zone. Negele is over 310 km south-east of Awassa. The area is on a plateau at the western edge of the Liben plains (site ET062). The forest is dominated by Juniperus procera, which forms a relatively open canopy at 25 m. Juniperus procera dominated forests are more usually found at higher altitudes than at Mankubsa–Welenso. Other species that form a lower stratum include various Acacia spp., Olea europea cuspidata, Combretum spp., Maytenus sp., and Rhus sp. A ground-cover of tall grasses includes Hyparrhenia spp. and Cympopogon spp. The soils in this area are shallow sands and gravels, and as a consequence are easily eroded.
See Box and Tables 2 and 3 for key species. Tauraco ruspolii and Serinus xantholaema both occur, but are uncommon. Among Somali–Masai biome species known from the area are Calandrella somalica, Cisticola bodessa, Sylvia boehmi and Sylvietta isabellina. Other species of interest recorded from the site include Accipiter ovampensis and Nectarinia erythrocerca. In addition, one species of the Sudan–Guinea Savanna biome has been recorded at this site; see Table 3.
