The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable".
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit.
Speke's gazelle is the smallest of the gazelle species. It is confined to the Horn of Africa, where it inhabits stony brush, grass steppes, and semi deserts. This species has been sometimes regarded as a subspecies of the Dorcas gazelle, though this is now widely disregarded. Severe habitat fragmentation means it is now impossible to assess the natural migratory or nomadic patterns of G. spekei. Its numbers are under threat, and despite an increase in population, the IUCN in 2007 announced its status had changed from vulnerable to endangered. A captive population is maintained, and the wild population exists in the lower tens of thousands. As of 2008, this gazelle is classified as endangered under the IUCN Red List.
The Bornean yellow muntjac is a muntjac species endemic to the moist forests of Borneo.
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or conservation dependent.
The Sunda scops owl is a small brown owl native to the Sunda Islands.
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss.

The Viverrinae represent the largest subfamily within the Viverridae comprising five genera, which are subdivided into 22 species native to Africa and Southeast Asia. This subfamily was denominated and first described by John Edward Gray in 1864.
The Hainan Island shrew is a species of mammal in the family Soricidae native to China and Vietnam. The IUCN has insufficient data to assess the level of population and its trend.
The Vietnam ferret-badger is a member of the family Mustelidae native to Vietnam. It was described in 2011 and is known from only two specimens.

Urva is a genus comprising the Asian mongooses within the mongoose family Herpestidae. Species in the genus were formerly classified in the genus Herpestes, which is now thought to comprise exclusively African mongooses; phylogenetic evidence indicates that the Asian mongooses form a monophyletic group and had an Asian common ancestor. Urva forms a clade with Xenogale and Atilax, while Herpestes forms a clade with all other African mongoose species.
