During the 1990s, wolf populations in Gosh Meda and Guguftu became extinct. In both cases, the extent of Afroalpine habitat above the limit of agriculture had been reduced to less than 20 km2. The EWCP team confirmed the extinction of a wolf population in Mt. Guna in 2011, whose numbers had been in single figures for several years. Habitat loss in the Ethiopian highlands is directly linked to agricultural expansion into Afroalpine areas. In the northern highlands, human density is the among the highest in Africa, with 300 people per km2 in some localities, with almost all areas below 3,700 m having been converted into barley fields. Suitable areas of land below this limit are under some level of protection, such as Guassa-Menz and the Denkoro Reserve, or within the southern highlands, such as the Arsi and Bale Mountains. The most vulnerable wolf populations to habitat loss are those within relatively low-lying Afroalpine ranges, such as those in Aboi Gara and Delanta in North Wollo.
