Over the last 30 years the African wild dog population has declined dramatically. Dogs have disappeared from 25 of the 39 countries in which they were previously found, and only 6 populations are believed to number more than 100 animals. Today it is believed that between 3,000 and 5,500 dogs remain in 600-1,000 packs only and most of these are to be found in eastern and southern Africa.
Dragonflies, those beautiful and colourful creatures which can often be seen hovering above water, pre-date dinosaurs. Today, some 5,000 species have been described and many more await discovery and description. The value of dragonflies lies in their beauty and distinctive colours which make them valuable subjects for research on insect behaviour, both for ecology and art; the fact that their larvae are aquatic makes them a good indicator of water quality; and because they are predators, they are particularly useful in the control of mosquitoes which pass on diseases to human beings.
The Ethiopian wolf is one of many species endemic to the highlands of Ethiopia but with only about 400 adults remaining, it is also the most endangered canid in the world. The main threats to this creature are loss of habitat to subsistence farming and livestock over-grazing, human development with all its subsidiary effects whereby human activity encroaches on the wolf's territory. Added to this, the small size of the remaining population has also brought with it problems of inbreeding, leading to a loss of genetic diversity, disease and hybridisation.
Wild caprinae, including sheep and goats, are an extremely valuable group of mammals. While most live in mountains, some inhabit desert grasslands, tropical forests or even arctic tundra. They range in size from the 30kg goral to the 350kg musk ox and display a variety of horn shapes and sizes as well as coat and body coloration. They are highly prized by hunters on account of their horns and their coats. Today, despite their important domestic relations, many wild caprinae are in danger of being lost forever: over 70 of caprinae taxa are threatened and over 30 endangered or critical.
There are currently three species of Asian rhino: the Indian or greater one-horned Asian rhino, the Javan or lesser one-horned Asian rhino and the Sumatran or Asian two-horned rhino. Today, all three are threatened with extinction and two, the Sumatran rhino and Javan rhino, critically so. Although the Indian rhino is to be found in greater numbers than the other two, the threats to this species nevertheless remain significant.
