Wildlife conservation efforts are increasingly faced with declining, overcrowded or fragmented populations, environmental contamination, and the introduction of new species of either competitors or pathogens. These efforts are coming under increased public scrutiny in their attempt to balance human social and economic needs with those of wildlife. The integration of veterinary medicine as part of a multidisciplinary approach to conservation can assist in the successful planning, implementation and evaluation of conservation projects. Beyond the role of immobilizing animals, veterinarians can contribute to assessing and monitoring the health of wild populations, and can train others in modern approaches to working with and caring for wildlife.

The Lao People's Democratic Republic (PDR) has long been a white spot on maps depicting national parks and similar protected areas. This changed dramatically with the official declaration in October 1993 of 18 protected areas covering over 10 per cent of the country's land surface. Among the countries of South East Asia Lao PDR now ranks among those with the highest proportion of land under legal protection. The political climate seems favourable and additional areas may still be added. System planning and, increasingly now, the management of declared areas has been carried out by the Protected Areas and Wildlife Division of the Centre for Protected Areas and Watershed Management (PAWM), Forest Department, with funding by the Swedish International Development Agency (SIDA) and technical support from IUCN-The World Conservation Union. Some of the most vulnerable species, such as the Javan rhinoceros Rhinoceros sondaicus, may already be extirpated, but most species and ecosystems have good prospects of survival if management of the reserves and some wider conservation initiatives can be implemented.

The wild alala Corvus hawaiiensis population has been declining for many years and only three pairs of birds are currently reproductively active on the island of Hawaii. At the recommendation of a committee formed by the National Academy of Sciences, a restoration programme was initiated in 1993 by The Peregrine Fund in collaboration with private land-owners, the US Fish and Wildlife Service, National Biological Service and the State of Hawaii. The restoration programme includes removing eggs from wild nesting birds for artificial incubation, handrearing and reintroduction. In two breeding seasons (1993, 1994), 17 eggs were removed from alala nests in the wild. Three eggs were infertile, 13 chicks hatched and 12 alala were successfully reared (hatchability: 93 per cent; survivability: 92 per cent). Four of these chicks were sent to the State of Hawaii's Olinda Endangered Species Propagation Facility, while four chicks from this facility were sent to the reintroduction programme. Twelve alala have been released by The Peregrine Fund: five in 1993 and seven in 1994. Three of the five birds released in 1993 and all seven of the birds released in 1994 are currently surviving in the wild.

The Alaotran gentle lemur Hapalemur griseus alaotrensis is found only in the marsh vegetation surrounding Lac Alaotra in Madagascar. This habitat is shrinking and becoming fragmented due to conversion to rice cultivation. In addition, lemurs are hunted for pets and food. There is no protected area within their limited range. This paper presents the results of a 6-month field study assessing the distribution, population size and conservation status of the lemur. The population consists of about 7500 animals, split into at least two subpopulations. If no conservation action is taken in the near future, drainage of the remaining 13,000 ha block of marsh vegetation will probably lead to the extinction in the wild of this primate taxon.

During recent surveys in the Cordillera de Coldn, a semi-isolated mountain range in northern Peru, observations were made and information collected on three species of mammals considered globally threatened with extinction – yellow-tailed woolly monkey Lagothrix flavicauda, Andean night monkey Aotus miconax and spectacled bear Tremarctos ornatus. The yellow-tailed woolly monkey has an extremely restricted range, in which extensive deforestation is occurring, and the species is also heavily hunted. The urgent establishment of an effectively protected area in the Cordillera de Colán is strongly recommended in order to help secure the future for this poorly known primate and other mammal and bird species of conservation importance.
