Threats to wild dogs
The
African wild dog has declined dramatically over the past 30 years. Between 3,000
and 5,000 wild dogs remain in total and most of these are in southern and eastern
Africa. The pressures that bear directly on the survival of wildlife species
such as the African wild dog can be attributed broadly to a slow but continuous
loss of wilderness habitat and the concurrent decline of wildlife populations
that depended on those habitats. Additionally, as competition for resources
increases with a rapidly growing human population, the frequency of conflict
with people escalates, resulting in damaging perceptions and the persecution
of wildlife, while at the same time the threat of domestic-animal diseases becomes
increasingly pronounced.
Wild
dogs range widely so that even those within protected areas often contact human
activity outside the reserve boundaries. Outside the protected areas, wild dogs
face persecution by man that is often linked to the unfounded negative attitudes
and images connected with the wild dog. As a general
rule, African wild dogs are thought to be dangerous, vicious, and problematic.
Personal injury is non-existent and loss of livestock from wild dogs is infrequent.
However, wild dogs that come into contact with local farmers are either shot
or poisoned due to the hostility and fear most people feel toward them. Furthermore,
wild dogs are also frequently found, inside and outside of reserve boundaries,
dead from snares and vehicle accidents.
Wild
dogs that are in contact with human activity are also threatened by domestic-animal
diseases. The constant social contact, such as that described during the hunting
rally, between all
wild dogs in a pack means that any virus, once started in a pack, will quickly
and effectively spread to all the dogs in the pack. Wild dog populations in
Kenya and Tanzania were decimated by
the rapid spread of disease between packs in the early 1990's. Viruses known
to be fatal or cause significant mortality in wild dogs include rabies and canine
distemper. Although protected areas are available to this endangered carnivore,
the area of land devoted to wilderness and the wildlife populations that it
supports is declining. As a result, the daily survival of individual wild dogs
is growing steadily more difficult. Despite man's historical persecution of
this fascinating canid, as well as its vulnerability to domestic dog diseases,
the loss of habitat from expanding human populations ultimately puts the greatest
pressure on the last of the continent's wild dogs. As land-use policies that
will impact the remaining wildlife continue to be implemented, the long-term
survival of the African wild dog hangs in uncertainty.
