The ring-tailed lemur Lemur catta is generally considered to be a species of dry deciduous forest, gallery forest and spiny thorn scrub at relatively low altitudes. During a survey of the summit zone of the Andringitra Massif, one of the most climatically extreme areas on Madagascar, we recorded this species above the tree-line at 2520 m in an area composed mostly of exposed rock, low ericoid bush and subalpine vegetation. Information was collected on food plants consumed by this species. This pelage coloration of the local population of L. catta differed from museum specimens and photographs taken from other areas of this species's range. The taxonomic status of the Andringitra population is in need of further study.

Increasing denouncement of African game legislation as inappropriate law imposed by the former colonial authorities is viewed with concern and condemned as mistaken. The necessity for the rule of law is argued and the good intent behind the institution of game laws. Abrogation of such laws will not lead to a lessening of the increasing destruction of African wildlife. The author was consultant to the Government of Botswana for the drafting of its new Wildlife Conservation and National Parks Act, 1992.

Project Angonoka, in its aim to conserve the endangered angonoka or ploughshare tortoise Geochelone yniphora in north-western Madagascar, has given a high priority to working with local people. Many of the environmental changes threatening the angonoka also cause difficulties for local people. An environmental awareness campaign has used the angonoka as a main theme, as an animal unique to the region whose near extinction symbolizes the impact of environmental changes occurring in the area. This campaign has stimulated the creation of village environmental associations. The activities undertaken by these associations have demonstrated a local willingness to manage and conserve their environment, and show how promotion of a flagship species can stimulate more general environmental conservation and sustainable development.

Selective logging is the predominant method of commercial timber exploitation in South East Asia. Its effects upon mammalian carnivores have seldom been addressed, despite the vulnerability of these animals at the top of many food chains. The authors investigated the effects of logging by comparing the abundance of sympatric civet species, which display feeding strategies ranging from strict carnivory tofrugivory, in primary and selectively logged rainforest in the Malaysian state ofSabah in northern Borneo. All species occurred in disturbed forest, but the overall density of civets in logged forest (6.4 individuals per sq km) was found to be significantly lower than in primary forest (31.5 individuals per sq km). This reflected a marked reduction in the abundance of civets from the predominantly carnivorous subfamilies Viverrinae and Hemigalinae.

It has been accepted traditionally that biodiversity is concentrated in the tropics. However, threatened temperate areas in southern South America, South Africa, New Caledonia, Australia and the Holarctic possess a significant number of unique taxa. Phylogenetic information encoded in cladograms can be used to develop indices for measuring biodiversity. Application of these indices to Asteraceae (Angiosperms) and Curculionoidea (Coleoptera) indicates the relevance of the temperate areas to biodiversity conservation: they are rich in phylogenetically valuable species and are environmentally threatened.

Reports of the Tibet red deer, a subspecies of Cervus elaphus, have been so few in recent years that there were fears that the animal was extinct. A survey in a mountainous region of south-east Tibet in October 1995 found evidence that a few deer survive in one small area and possibly two others in high-altitude valleys of the tributaries of the Subansiri River. The most exciting finding of the survey, however, was an estimated 200-strong population of this deer in high rolling hills near the village of Zhenqi, north of the Yarlung Tsangpo River. This is the only known viable population of the deer and, although some hunting occurs, including by professional poachers from outside Tibet, the fact that it survives is an indication of the tolerance of the local people. The Tibet Forest Bureau has agreed to fund guards and to establish a reserve for the deer in co-operation with local people.

The late Sir Peter Scott, a former President of Fauna and Flora International, proposed the idea of Red Data Books as conservation tools more than 30 years ago. Today, the international Red Data Book programme appears to be effectively at an end, with priority being given to Action Plans and Conservation Assessment Management Plans for groups oftaxa. These, however, cannot entirely replace Red Data Books, and the author of this paper argues that Red Data Books have many vital roles to play in species conservation and makes a plea for their renascence.

In 1994 the authors made two rapid assessments of wildlife in the remote Namcha Barwa region, south-eastern Tibet, China. They conducted interviews, examined and recorded trophies in the possession of local Menba, Luoba and Kangba Tibetans and made opportunistic field observations. Despite the extensive forests in this extremely remote region, wildlife populations appeared to be low except in inaccessible areas along county borders. Frequent reports of tiger predation on cattle, horses and mules in glaciated valleys on the south slope of the Himalayas may indicate a shortage of natural prey. Uncontrolled hunting, human population growth and expedient economic development threaten the survival of large mammals in the region.

Brazilian crocodiles are threatened by gold mining and related mercury- and lead-contamination of animals and their habitat, deforestation, increasing use of land for agriculture and destructive forestry, increased human incursions, and commercial and subsistence hunting for skins and meat. Contaminated meat is consumed by local people and miners, and meat and skins are exported to global markets. Already depleted black caiman Melanosuchus niger populations are seriously affected.

Sustainable development is increasingly being seen as a legitimate, and locally critical, element in wildlife conservation. However, relatively few studies of projects attempt to combine conservation and development goals. The Hadejia—Nguru Wetland Conservation Project in Nigeria grew out of a concern for wildlife (particularly wetland birds), but has expanded to address issues of environmental sustainability and economic development at both the local and the regional scale. This paper assesses the achievements of the project's approach.

The mountain tapir has already disappeared from parts of its range in the high Andes of South America and remaining populations are severely threatened by hunting and habitat destruction. With an estimated population of fewer than 2500 individuals, urgent measures are necessary to secure a future for the species. This paper presents an overview of the species throughout its range as well as some of the main results of the author's studies on tapir ecology. Finally, a plea is made for conservation action in Sangay National Park, which is one of the species's main strongholds.

The São Tomé white-toothed shrew Crocidura thomensis is endemic to the island of São Tomé in the Gulf of Guinea. This species was discovered in 1886 and since then has been recorded from fewer than 10 locations. This paper summarizes all published and unpublished information on C. thomensis. The species is currently listed by the IUCN as ‘Insufficiently Known’, but using the new IUCN Red List Categories is re-classified as ‘Vulnerable B1 + 2c’. Threats to the survival of C. thomensis include deforestation, plantation redevelopment and predation by introduced mammals.

Four endangered species of marine turtle nest on the southern beaches of Bioko Island, Equatorial Guinea. The turtles and their eggs are an important traditional source of food for the people of the area and turtle populations have apparently declined considerably, probably because of overexploitation. This paper reviews what is known about Bioko's marine turtles, their nesting seasons, population trends, use by humans, conservation status and recent conservation efforts. Recommendations are made for additional research and conservation action.

Surveys of river otters Lutra lutra on Kinmen and Little Kinmen islands were carried out in 1992 and 1993. In order to record sightings of otters in the past, 12 Kinmen residents who had seen or caught otters before were interviewed. Interview results indicated that the otter is a resident, breeding species on Kinmen. Survey results indicated presence of otters throughout Kinmen and in many sites on Little Kinmen. However, habitat degradation, including pollution and drought, may pose serious threats to the continued existence of the species on both islands.

This paper presents the results of surveys conducted in 1994 to establish the population size and density, and conservation status of red howler monkeys Alouatta seniculus insulanus and white-fronted capuchin monkeys Cebus albifrons trinitatis in the Trinity Hills, Bush-Bush and Central Range Wildlife Sanctuaries of the Republic of Trinidad and Tobago, West Indies. Populations of the red howler and capuchin monkey have declined by about 25 per cent in Bush-Bush Wildlife Sanctuary over the past 25 years. This decrease was attributed to intensive hunting pressure and habitat destruction. These factors have also caused monkey population declines in the Trinity Hills and Central Range Wildlife Sanctuaries. Recommendations are presented for the local government to enhance the protection of wild monkeys and their habitats in Trinidad.

Some megapode populations have already become extinct in parts of Indonesia because of the increasing human population, improved infrastructure and the abandonment of traditions governing the collection of megapode eggs for human consumption. In other areas megapode eggs are being collected unsustainably, while in more remote areas traditions, and megapode populations, are still intact. The authors examine the ways that traditional egg-collecting methods could be incorporated successfully into megapode conservation projects.

Bukit Barisan Selatan National Park in south-west Sumatra is one of the largest protected areas in Sumatra and thus of considerable importance to the conservation of biodiversity in Indonesia. Until recently, little was known of the wildlife in the park. The authors' surveys document the presence of an intact community of the birds and mammals known to occur in lowland Sumatran rain forests. While hunting and collection of forest products threaten a number of plant and animal species in the park, the primary threat to the park's integrity is from agricultural encroachment and expansion of enclaves beyond their boundaries. The future survival of Bukit Barisan National Park and its wildlife requires that active measures be taken to curb non-sustainable exploitation of plants and wildlife. It will also be necessary to resolve land-use conflicts with communities in, and adjacent to, the park.

Indonesia, like many other developing countries, is turning to ecotourism in an attempt to integrate the goals of development and nature conservation. Although ecotourism may be a valuable tool for preservation of biodiversity, it can have long-term negative effects on reserves, wildlife and local communities if improperly managed. In this study the authors evaluated ecotourism in the Tangkoko DuaSudara Nature Reserve, North Sulawesi, by examining trends in visitor numbers, the tourist experience, the distribution of tourist revenues, and tourist impact on the Sulawesi black macaque Macaca nigra and spectral tarsier Tarsier spectrum. The data collected showed that, although tourism is expanding rapidly, local benefits are not being fully realized, the reserve does not generate enough money to implement management, and primate behaviour is being affected. There is urgent need for a change in legal status of the reserve if ecotourism is to be managed. National park status would accommodate ecotourism planning and development, provide for greater participation by the local community, and allow for increased revenues for management.

The issues of habitat loss and hunting are of paramount importance to wildlife conservation in Asia. In Sulawesi, Indonesia, these problems are having a serious impact on the vertebrate fauna. Using line-transect methods, the densities of 11 species of large birds and mammals were compared between 1979 and 1994 in the Tangkoko-DuaSudara Nature Reserve in North Sulawesi. During those 15 years, populations ofanoa Bubalus depressicornis, bear cuscus Phalanger ursinus, crested black macaque Macaca nigra, maleo Macrocephalon maleo and red junglefowl Gallus gallus declined by 50–95 per cent while populations of Sulawesi pig Sus celebensis, Tabon scrubfowl Megapodius cumingii, Sulawesi tarictic hornbill Penelopides exarhatus and red-knobbed hornbill Aceros cassidix increased by 5–100 per cent. We considered hypotheses for these changes: habitat loss outside the reserve, habitat degradation inside the reserve, and hunting. Only hunting adequately explained the pattern of changing densities observed. Unless protection from hunting is enforced for these species, we may soon witness the demise of these unique animals in North Sulawesi and possibly throughout the island.
