The wild buffaloes, gaur Bos gaurus and banteng Bos javanicus, are among the most threatened mammals in Vietnam but little information is available on their status and distribution. Over 2004–2007 I undertook surveys in three Vietnamese distribution strongholds of the Vulnerable gaur and Endangered banteng: Ea So Nature Reserve and Yok Don and Cat Tien National Parks. A total of 22 herds with 121 gaur and seven herds with 49 banteng were observed. Herd sizes of both species were generally lower than those recorded in Thailand and Malaysia. Most of the herds were observed in remote areas, showing that the species are probably staying away from areas with human activity. No banteng were found in Cat Tien National Park. Of the other wild buffalo species the Critically Endangered kouprey Bos sauveli and Endangered water buffalo Bubalus arnee were not observed in the three protected areas but the Near Threatened serow Capricornis milneedwardsii was occasionally observed in all three areas. Illegal hunting, habitat degradation and disturbance appear to be the most significant threats to gaur and banteng in the areas surveyed. It is essential to have effective law enforcement to eliminate human impacts on these two species, and an adequate conservation strategy to secure their long-term survival.

The population and conservation status of crocodiles throughout West and Central Africa is poorly known and the IUCN Crocodile Specialist Group's highest priority recommendations are country status surveys and examination of potential threats. This study presents survey data and a review of the conservation status of the Nile crocodile Crocodylus niloticus, slender-snouted crocodile Mecistops cataphractus and African dwarf crocodile Osteolaemus tetraspis at 67 sites throughout Ghana and Côte d'Ivoire. No crocodiles were sighted in 31.5% of surveys but, where encountered, densities averaged 0.90 crocodiles sighted km-1. The most frequently encountered crocodile was C. niloticus (94% of sightings) with population structure highly biased to individuals < 1 year of age (41.4%). Only 14 M. cataphractus were observed. Local informants report that crocodiles were more common 10–20 years ago than at present. There is now little commercial harvest, which includes limited use in the bushmeat and traditional medicine markets, because of the crocodile's scarcity. Habitat encroachment and incidental bycatch in fishing devices appear to be the major threats. Actions needed to improve the conservation status of crocodile populations in both countries, and throughout the region, are discussed.

Attenborough's long-beaked echidna Zaglossus attenboroughi is known from a single specimen collected in the Cyclops Mountains of northern Papua in 1961, and has previously been considered to be extremely rare if not already extinct. New fieldwork to investigate the continued survival of Z. attenboroughi was conducted on the north and south slopes of the Cyclops Mountains in May 2007 using community interviews, sign surveys and visual encounter surveys. Many villagers recognized photographs of long-beaked echidnas, were able to describe key biological characteristics of echidnas, and reported several recent sightings below 300 m elevation, referring to the animal as payangko. Although no echidnas were observed during fieldwork, diagnostic echidna feeding signs (imprints of nose pokes) were detected from < 300 m to 1,250 m and possibly up to 1,700 m elevation. These extensive reports and observations confirm that long-beaked echidnas are still present in the Cyclops Mountains, and descriptions provided by local informants strongly suggest that the reports refer to Z. attenboroughi. However, the species remains threatened by human impacts, primarily subsistence hunting and habitat loss. Efforts are now being made to learn more about the relationship of Attenborough's long-beaked echidna to all other Zaglossus species, and a project is being initiated with local communities to monitor sightings and increase awareness of this rare and evolutionarily distinct mammal.

In September 2007 unusual precipitation patterns created conditions in the eastern steppe of Mongolia (drought conditions in many places and wet conditions in one area) that led to the observation of a historically large Mongolian gazelle Procapra gutturosa herd (> 200,000). A model developed to predict gazelle occurrence based on satellite imagery of vegetation productivity correctly identified the region where the mega-herd was located. Additionally, few gazelles were observed in large portions of adjacent, suitable habitat that either had intense insect activity or were undergoing intensive oil development. Because Mongolian gazelles appear to undertake long-distance nomadic movements to cope with a highly variable environment and food availability, development activities that discourage use of limited suitable habitat may ultimately reduce gazelle fecundity or increase mortality. Landscape level conservation strategies that prevent habitat loss and allow access to all of the grasslands seem preferable to strategies that focus on enhancing a handful of protected areas.
