Species surveys

Although most antelope species still exist in large numbers in sub-Saharan Africa (some in hundreds of thousands), up to three-quarters of the species are in decline. Threats to their survival arise from the rapid growth of human and livestock populations, with consequent degradation and destruction of natural habitats, and excessive offtake by meat hunters.

Conifers are one of the world's most important resources of timber. If managed wisely and used sustainably, these resources will provide wood for a multitude of purposes, virtually indefinitely. Additional products include resins and their derivatives, and even medicinal extracts, for example taxol now used in the treatment of cancer. Conifers occur on all continents except Antarctica.

These 12th proceedings provide an overview of the ongoing research and management activities on polar bears on the circumpolar Arctic. Together with the previous proceedings, they provide an historic record of the international effort in protecting polar bears from over-harvest, and document more recent concerns of threats arising as a consequence of increased human activities in both the Arctic and in regions far beyond the realm of polar bears.

The eight species of bear live in more than 65 countries or autonomous regions in four continents, in a variety of habitats from tropical rainforests to arctic ice. Numerous human cultures around the world symbolically or physically try to incorporate the power of bears into their people.

Deer are a unique group of mammals recognised for their grace and beauty. Some are also prime examples of flagship species, whose continued survival sustains the complex interplay of flora and fauna. Today many species are under threat of extinction.

The first comprehensive treatment of North American rodents of conservation concern. This action plan summarises the rodent fauna of North America and provides available information on every rodent taxon that has been considered to be of conservation concern by state, provincial and private conservation agencies and regional experts.

Despite their low species density, hyaenas are both unique and vital components of most African and some Asian ecosystems. Although there are only 4 species, they tend to clash with the interests of humans to a greater extent than many other mammals and one of the biggest obstacles facing those committed to the conservation of this species is the negative feelings that many people have towards hyaenas.
