Justification:

A small population persists in the southern Algerian mountains; Hoggar and Tassili National Parks. This is the only population in a Mediterranean country. The Algerian population is presumably very small although it has not been censused. The most recent record is of a group of 9 individuals in 1996 at between 11-12 East and 24-25 North (near the Libyan border) in Tassili National Park (K. de Smet pers. comm. 2007).

The Mediterranean population is smaller than 50 (likely smaller than 25) and is very close to extinction. It is isolated from other populations. The population in the Mediterranean region probably has always been low, but in the past there was contact with Sahel populations that allowed the Algerian population to be sustained. Now these adjacent Sahel populations are extirpated.

Although the single Mediterranean population is in a protected area (the two connected National Parks mentioned above), this does not afford the species effective protection from trapping.

Geographic Range [top]

Range Description:Historical data indicate that African Wild Dogs were formerly distributed throughout sub-Saharan Africa, from desert (Lhote 1946) to mountain summits (Thesiger 1970), and probably were absent only from lowland rainforest and the driest desert (Schaller 1972). They have disappeared from much of their former range: 25 of 39 former range states no longer support populations (Fanshawe et al. 1997). The species is virtually eradicated from West Africa, and greatly reduced in central Africa and north-east Africa. The largest populations remain in southern Africa (especially northern Botswana, western Zimbabwe, eastern Namibia, and Kruger National Park, South Africa) and the southern part of East Africa (especially Tanzania and northern Mozambique). Details of current distribution and status are in Woodroffe et al. (1997) and Sillero-Zubiri et al. (2004).

Population [top]

Population:African Wild Dogs are rarely seen, even where they are relatively common, and it appears that populations have always existed at very low densities. Ginsberg and Woodroffe (1997) used population densities in well-studied areas to estimate the size of remaining populations. These estimates suggest that between 3,000-5,500 free-ranging wild dogs remain in Africa.

Estimated sizes and trends of national wild dog populations in Africa, updated from Woodroffe et al. (1997), can be found in Sillero-Zubiri et al. (2004).
Current Population Trend:Decreasing

Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:African Wild Dogs are generalist predators, occupying a range of habitats including short-grass plains, semi-desert, bushy savannas and upland forest. While early studies in the Serengeti National Park, Tanzania, led to a belief that wild dogs were primarily an open plains species, more recent data indicate that they reach their highest densities in thicker bush (e.g., Selous Game Reserve, Tanzania; Mana Pools National Park, Zimbabwe; and northern Botswana). Several relict populations occupy dense upland forest (e.g., Harenna Forest, Ethiopia: Malcolm and Sillero-Zubiri 2001; Ngare Ndare Forest, Kenya). African Wild Dogs have been recorded in desert (Lhotse 1946), although they appear unable to establish themselves in the southern Kalahari (M.G.L. Mills, unpubl.), and montane habitats (Thesiger 1970; Malcolm and Sillero-Zubiri 2001), although not in lowland forest. It appears that their current distribution is limited primarily by human activities and the availability of prey, rather than by the loss of a specific habitat type.

African Wild Dogs mostly hunt medium-sized antelope. Whereas they weigh 20-30 kg, their prey average around 50 kg, and may be as large as 200 kg. In most areas their principal prey are Impala (Aepyceros melampus), Greater Kudu (Tragelaphus strepsiceros), Thomson's Gazelle (Gazella thomsonii) and Common Wildebeest (Connochaetes taurinus). They will give chase of larger species, such as Common Eland (Tragelaphus oryx) and African Buffalo (Syncerus caffer), but rarely kill such prey. Small antelope, such as dik-dik (Madoqua spp.), Steenbok (Raphicerus campestris) and duiker (tribe Cephalophini) are important in some areas, and warthogs (Phacochoerus spp.) are also taken in some populations. Wild dogs also take very small prey such as hares, lizards and even eggs, but these make a very small contribution to their diet.

Threats [top]

Major Threat(s): The principal threats to African Wild Dogs are conflict with human activities and infectious disease. Both of these are mediated by habitat fragmentation, which increases contact between wild dogs, people and domestic dogs. The important role played by human-induced mortality has two long-term implications. First, it makes it likely that, outside protected areas, wild dogs may well be unable to co-exist with the increasing human population unless better protection and local education programmes are implemented. This will be a serious problem for wild dog populations outside protected areas. Second, wild dog ranging behaviour leads to a very substantial "edge effect", even in large reserves. Simple geometry dictates that a reserve of 5,000 km² contains no point more than 40 m from its borders - a distance well within the range of distances travelled by a pack of wild dogs in their usual ranging behaviour. Thus, from a wild dog's perspective, a reserve of this size (fairly large by most standards) would be all edge. As human populations rise around reserve borders, the risks to wild dogs venturing outside are also likely to increase. Under these conditions, only the very largest unfenced reserves will be able to provide any level of protection for wild dogs. In South Africa, proper fencing around quite small reserves has proved effective in keeping dogs confined to the reserve (although fencing has costs, as well as benefits, in conservation terms).

Even in large, well-protected reserves, or in stable populations remaining largely independent of protected areas (as in northern Botswana), wild dogs live at low population densities. Predation by lions, and perhaps competition with hyaenas, contribute to keeping wild dog numbers below the level that their prey base could support. Such low population density brings its own problems. The largest areas contain only relatively small wild dog populations; for example, the Selous Game Reserve, with an area of 43,000 km² (about the size of Switzerland), contains about 800 wild dogs. Most reserves, and probably most wild dog populations, are smaller. For example, the wild dog population in Niokolo-Koba National Park and buffer zones (about 25,000 km², larger than the state of Israel) is likely to be not more than 50-100 dogs. Such small populations are vulnerable to extinction. "Catastrophic" events such as outbreaks of epidemic disease may drive them to extinction when larger populations have a greater probability of recovery - such an event seems to have led to the extinction of the small wild dog population in the Serengeti ecosystem on the Kenya-Tanzania border. Problems of small population size will be exacerbated if, as seems likely, small populations occur in small reserves or habitat patches. As discussed above, animals inhabiting such areas suffer a strong "edge effect". Thus, small populations might be expected to suffer disproportionately high mortality as a result of their contact with humans and human activity.

There are no commercial uses for wild dogs, other than non-consumptive ecotourism.

Conservation Actions [top]

Conservation Actions: The species is not listed on CITES.

Wild dogs are legally protected across much of their range. However, this protection is rarely enforced and wild dogs are extinct in several countries despite stringent legal protection. Outside reserves, legal protection may have questionable value when it concerns a species that comes into conflict with people, often in remote areas with poor infrastructure. Under such circumstances, legal protection may serve only to alienate people from conservation activities.

The occurrence of wild dogs in protected areas is described in detail in Fanshawe et al. (1997). The largest populations inside protected areas occur in Tanzania: Selous Game Reserve and Ruaha National Park; South Africa: Kruger National Park; Botswana: Chobe National Park and Moremi Wildlife Reserve; and Zimbabwe: Hwange National Park.

Virtually no conservation measures have been implemented specifically for wild dogs. The establishment of very large protected areas (e.g., Selous Game Reserve, Kruger National Park), as well as conservancies on private and communal land, has ensured wild dogs' persistence in parts of eastern and southern Africa, and maintenance of such areas remains the highest priority for wild dog conservation. Attempts are underway to re-establish wild dogs in a network of very small reserves in South Africa, but this approach will demand intensive management in perpetuity and need not, at present, be used as a model for wild dog conservation elsewhere.

Conservation priorities include: (i) to maintain and expand connectivity of habitat available to wild dogs, particularly in northern Botswana/eastern Namibia/western Zimbabwe, South Africa/western Mozambique/south-east Zimbabwe, northern South Africa/south-east Botswana/south-west Zimbabwe and southern Tanzania/northern Mozambique; (ii) to work with local people to reduce deliberate killing of wild dogs in and around these areas, and also in smaller populations in Senegal, Cameroon and Kenya; (iii) to establish effective techniques for protecting small wild dog populations from serious infections such as rabies and distemper; (iv) to carry out surveys to establish the status of other potentially important populations, particularly in Algeria, Angola, Central African Republic, Ethiopia, Mozambique and Sudan, and (v) to continue long-term monitoring of 'sentinel' populations to identify emerging threats. Re-establishment of extinct populations through reintroduction currently has a low priority in most areas, although natural recolonizations should be encouraged.

Occurrence in captivity
There are more than 300 wild dogs in captivity in 55 zoos, as listed on ISIS and as many as 200 additional animals occur in zoos and private collections, particularly in South Africa.

Early attempts to reintroduce captive-bred animals to the wild were hampered by the dogs' poor hunting skills and naive attitudes to larger predators. However, recent reintroductions have overcome this problem by mixing captive-bred dogs with wild-caught animals and releasing them together. This approach has been very valuable in re-establishing packs in several fenced reserves in South Africa, but is not considered a priority in other parts of Africa at present. Nevertheless, captive populations have important roles to play in developing conservation strategies for wild populations, through research (e.g., testing of vaccination protocols), outreach and education.

Gaps in knowledge
Several pieces of information are needed to enable more effective conservation of African wild dogs. These include: 1) establishing which techniques will be most effective and sustainable for protecting wild dogs from disease, including whether vaccinating wild dogs against rabies and distemper can ever be safe and effective, and whether other methods (including control or vaccination of domestic dogs) can reduce the risks to wild dogs; 2) determining the true impact of wild dogs on livestock under different conditions of husbandry, and the effectiveness of techniques to reduce this; 3) establishing the true impact of wild dogs on managed wild game and the effectiveness of techniques to resolve conflicts with game ranchers; 4) surveys of wild dog distribution and status are also required, particularly in Algeria, Angola, Cameroon, Central African Republic, Ethiopia, Mozambique and Sudan; 5) genetic research would be valuable to establish the distinctiveness of wild dog populations remaining in west, central and north-east Africa; and 6) the reasons for and degree of fluctuation in packs and populations need to be better understood. In addition, several aspects of wild dogs' basic biology require further study, particularly: 1) mechanisms of ranging and dispersal; 2) causes of increased mortality among dispersers; 3) reasons for large home range; 4) mechanisms of sex-ratio biasing; 5) paternity; and 6) communication.
