After Bale Mountains, the Simien Mountains host the second most important population of Ethiopian wolves. These rare animals are endemic to the Ethiopian Highlands, that is, they are found nowhere else in the world. The Simien Mountains, a World Heritage Site, is the inspiration behind their scientific name, Canis simensis – a species described in 1840 from a specimen collected there by German naturalist Eduard Rüppell. Compared to wolves in Bale, which are diurnal and relatively easy to find, Simien wolves are notoriously shy and difficult to observe. Reproduction is also not as good as in Bale: litter sizes are always small—seldom more than three pups—and several packs are not able to produce a litter each year. Wolf packs therefore remain small. In addition, some areas in Simien Mountains withstood many months of brutal fighting during the Tigray war until very recently. Recent research across the world have highlighted that human disturbance may shift animal activity to the night, with potential negative consequences on reproduction and survival. To address this question, after obtaining approval from the Ethiopian Wildlife Conservation Authority, EWCP launched in early March 2023 a GPS collaring study of Ethiopian wolves in Simien Mountains. This is the first time Ethiopian wolves are tracked after the first study conducted in 1988-1992 by Claudio in the southern slopes of Bale’ Sanetti Plateau using VHF collars.
