Ethiopian wolves (Canis simensis) are Africa’s most endangered carnivore, with approximately 500 individuals remaining along the country’s Afroalpine habitat, approximately half of which are found in the Bale Mountains. While habitat loss is a major threat to species survival, infectious disease epizootics have had serious impacts on wolf populations. Since 1992, the wolves in the Bale Mountains have faced eight major outbreaks from rabies and canine distemper viruses. Outbreaks are prompted by introduction of the viruses from domestic dogs. The density and social nature of the wolves allow for rapid virus transmission amongst and between packs; concerningly, outbreaks have resulted in extinctions of entire packs. To effectively manage this threat, the Ethiopian Wolf Conservation Programme and its partners have developed and applied a comprehensive conservation strategy, including preventive and reactive vaccination and disease monitoring in line with a One Health approach.
