More than half of the species' population lives in the Bale Mountains, where wolf density is high for a social carnivore of its size, and positively correlated with density of rodent prey and negatively with vegetation height (Sillero-Zubiri and Gottelli 1995). Highest wolf densities are found in short Afroalpine herbaceous communities (1.0–1.2 adults/km²); lower densities are found in Helichrysum dwarf-scrub (0.2/km²), and in ericaceous heathlands and barren peaks (0.1/km²). Wolves are also present at low density (0.1–0.2/km²) in montane grasslands at lower altitudes.
Elsewhere, overall wolf density is relatively lower. In Menz, wolf density was estimated at 0.2 animals/km² using transect data (Ashenafi 2001). Comparison of census transect data from recent comprehensive surveys (Marino 2003a) indicates higher abundance in North Wollo (0.20 ± 0.20 sightings per km), intermediate in Arsi and Guna (0.10 ± 0.11 and 0.10 ± 0.14, respectively), and lower in South Wollo and Simien (0.08 ± 0.13 and 0.06 ± 0.11, respectively). These results were supported by counts of wolf signs (i.e., diggings and droppings) and interview results.
A summary of population abundance and status in each region can be found in Sillero-Zubiri et al. (2004), with the most recent information on population status found in IUCN/SSC Canid Specialist Group (2011), and summarized above. Time series from long-term monitoring of wolves in the Bale Mountains of southern Ethiopia, spanning over 20 years, indicated marked variation in wolf abundance in association to rabies epizootics affecting high-density populations in 1991, 2003 and 2008 (Marino 2003b, Marino et al. 2006, IUCN/SSC Canid Specialist Group 2011). Population numbers returned to previous levels after the first two disruptions, evidencing resilience to catastrophes, but at very low density population growth was unexpectedly low, due to delays in the formation of new breeding packs (Marino et al. in review). Canine distemper (CDV) appears to be more important than previously thought, with CDV outbreaks affecting wolves across subpopulations in the Bale Mountains in 2005, 2006 (Malcolm 2006), and 2010 (Gordon et al. 2010).

Description complète des menacesTexte détaillé évaluation IUCNExpert
Continuous loss of habitat due to high-altitude subsistence agriculture represents the major threat. Sixty percent of all land above 3,200 m has been converted into farmland, and all populations below 3,700 m are particularly vulnerable to further habitat loss, especially if the areas are small and of relatively flat relief (Marino 2003a). Habitat loss is exacerbated by overgrazing of highland pastures by domestic livestock, and in some areas habitat is threatened by proposed development of commercial sheep farms and roads. Human persecution triggered by political instability in the past is currently less severe and associated with conflicts over livestock losses (Marino 2003a). Recent population decline in Bale has been mostly due to disease epizootics, with road kills and shooting as secondary threats. Rabies is a potential threat to all populations, with canine distemper also a concern in Bale. Most of these threats are exacerbated by the wolves' specialization to life in the Afroalpine ecosystem.
In Bale, the Ethiopian wolf hybridizes with domestic dogs (Canis familiaris). Gottelli et al. (1994) used mitochondrial DNA restriction fragments and microsatellite alleles to conclude that hybridization was relatively common in western Bale as a result of crosses between female wolves and male domestic dogs. Hybrids have shorter muzzles, heavier-built bodies and different coat patterns. Although hybrids are confined to the Web Valley in western Bale they may threaten the genetic integrity of the wolf population. Following hybridization, a population may be affected by outbreeding depression or reduction in fitness, although to date this does not seem to have taken place in Bale. Currently there is no indication of hybridization taking place outside western Bale.
There is no exploitation of the species for furs, body parts or other purposes.

The species is not included on the CITES Appendices. It has full official protection under Ethiopia's Wildlife Conservation Regulations of 1974, Schedule VI. Killing a wolf carries a sentence of up to two years.
The Ethiopian Wolf occurs in several protected areas: Bale Mountains National Park; Simien Mountains National Park; Borena Saiynt Regional Park (South Wollo); Guassa Community Conservation Area (North Shoa); Arsi Mountains Regional Park. As a result of boundary extensions (Simien) and new parks created (Arsi) the area of suitable wolf habitat within protected areas increased to 87%.
A number of important steps have been taken in the interests of conserving this endemic species, including: 1) a dog vaccination campaign in Bale, and vaccination campaigns in response to rabies outbreaks in dogs close to wolves in Menz and Simien; 2) sterilization programme for hybrids in Bale; 3) vaccination of wolves in response to rabies epizootics in parts of Bale; 4) community and school education programme in Bale and Wollo; 5) strengthening the capacity of the Bale Mountains National Park – funding patrolling, maintenance of infrastructure, etc.; 6) surveys to determine the persistence and status of all populations of wolves; 7) monitoring of all wolf populations; 8) A Strategic Planning workshop for Ethiopian wolf conservation held in Lalibela, February 2011, resulting in a National Action Plan for the next 10 years (IUCN/SSC Canid specialist Group 2011).
In 1983, the Wildlife Conservation Society established the Bale Mountains Research Project, which publicized the wolf's plight and started a regular monitoring programme for the species. A detailed four-year field study followed (Sillero-Zubiri 1994). Based on its findings, the IUCN/SSC Canid Specialist Group produced an action plan for the Ethiopian Wolf (Sillero-Zubiri and Macdonald 1997), which provided a detailed strategy for the conservation and management of remaining wolf populations. This plan advocated immediate action on three fronts – education, wolf population monitoring, and rabies control in domestic dogs – to conserve the Afroalpine ecosystem and its top predator. As a result, the Ethiopian Wolf Conservation Programme (EWCP) was established in 1995 by Oxford University with financial support from the Born Free Foundation, Frankfurt Zoological Society (FZS), the Wildlife Conservation Network and other donors. The Programme’s overall aim is to protect the Afroalpine ecosystem and many of its rare highland endemic plants and animals through better management in Bale and the establishment of other conservation areas in Menz and Wollo. The EWCP currently monitors the demography of the Bale and selected populations in South and North Wollo, supports park patrols within the wolf range, undertakes domestic dog control and the removal of dog-wolf hybrids. Additionally, the EWCP carries out a community conservation education campaign that targets people living inside the wolf's range and is aimed at improving dog husbandry and combating disease in the park and surroundings. A large-scale dog vaccination programme (targeting up to 5,000 dogs a year) seeks to reduce the occurrence of rabies and distemper within the Ethiopian wolf range and is backed up by further epidemiological and demographic studies. The EWCP is also active elsewhere in Ethiopia, with representatives surveying and monitoring all wolf ranges and implementing education campaigns about the plight of the species. Zelealem Tefera Ashenafi set up the Guassa Biodiversity Project in 1996, looking at the relationships between pastoralists and wildlife in the highlands of Menz. FZS and partners are working in North Ethiopia to protect the Afrolapine ecosystem, supporting the Simien Mountains National Park and creation of a new community conservation area in North Wollo.
There are no animals maintained in captivity.Although the behavioural ecology of the species is well known, research has focused largely in the optimal habitats in the Bale Mountains. Additional information on dispersal distance and survival would be useful. Investigation into the role of the species in the epidemiology of canid-related diseases is necessary. Studies on wolf-prey relationships and prey availability in the high risk populations of northern Ethiopia are also needed.
