Mammals

In some areas of western equatorial Africa, ape populations have declined by more than 50% over the last twenty years. By far the most serious short-term threats to apes in this region are poaching and disease epidemics. In the longer term, however, it is believed that habitat loss and disturbance will become as serious a threat as hunting and disease.

The Cross River gorilla (Gorilla gorilla diehli) is recognized by IUCN as Critically Endangered, and is the most threatened taxon of ape in Africa. Work during the last two decades has revealed that fewer than 300 Cross River gorillas may remain, spread across an area of about 12,000 km2. The outlook for these apes is far from hopeless, but a concerted and sustained effort will be required if their long-term survival is to be assured.

Numerous scientific studies show that biodiversity in Europe has been declining rapidly for some time and that this pattern has been matched by the great periods of expansion and intensification of land use. This first assessment of the Red List status of Europe’s and the European Union's mammals shows us that 15% of our species are threatened with extinction, 27% were identified as declining and another 33% had an unknown population trend.

Part 3 of the Antelopes, Global Survey and Regional Action Plans completes the coverage of the Ethiopian Fauna Region. What distinguishes this portion of the earth from others is the wealth of the megafauna, of which antelopes constitute a dominant component. All major climatic-vegetation zones are included, from the lowland rain forests of the Congo basin and West Africa to the Great Saharan Desert.

Over 30 organisations collaborated to produce this publication. It covers 295 terrestrial and marine species and subspecies of mammals, which were assessed within South African borders, excluding Swaziland and Lesotho.

This report has been produced by ZSL in collaboration with WWF, IUCN and SSC. It considers for the first time the current status and trends of global vertebrates in the context of human pressures, with a particular focus on threatened, novel and evolutionary distinct species.
