Nomascus is the second-most speciose genus of the gibbon family, Hylobatidae. Originally, this genus was a subgenus of Hylobates, with all individuals considered to be one species, H. concolor.
Species within Nomascus are characterized by 52 chromosomes. Some species are all-black, some are a lighter beige or peach hue, with a distinct black tuft of crown fur, while others have notable, light-colored cheek “patches”. Nomascus is endemic from southern China (Yunnan) to southern Vietnam, and can also be found on Hainan. Every species within this genus are either endangered or critically endangered; the Eastern black crested gibbon (Nomascus nasutus) has been deemed "the most-critically endangered ape species in the world".

Gibbons are apes in the family Hylobatidae. The family historically contained one genus, but now is split into four extant genera and 20 species. Gibbons live in subtropical and tropical forests from eastern Bangladesh to Northeast India to southern China and Indonesia.
Apes are a clade of Old World simians native to sub-Saharan Africa and Southeast Asia. Apes are more closely related to Old World monkeys than to the New World monkeys (Platyrrhini) with both Old World monkeys and apes placed in the clade Catarrhini. Apes do not have tails due to a mutation of the TBXT gene. In traditional and non-scientific use, the term ape can include tailless primates taxonomically considered Cercopithecidae, and is thus not equivalent to the scientific taxon Hominoidea. There are two extant branches of the superfamily Hominoidea: the gibbons, or lesser apes; and the hominids, or great apes.
The lar gibbon, also known as the white-handed gibbon, is an endangered primate in the gibbon family, Hylobatidae. It is one of the better-known gibbons and is often kept in captivity.
The hoolock gibbons are three primate species of genus Hoolock in the gibbon family, Hylobatidae, native to eastern Bangladesh, Northeast India, Myanmar, and Southwest China.
The silvery gibbon, also known as the Javan gibbon, is a primate in the gibbon family Hylobatidae. It is endemic to the Indonesian island of Java, where it inhabits undisturbed rainforests up to an altitude of 2,450 m (8,040 ft). It has been listed as Endangered on the IUCN Red List since 2008, as the wild population is estimated to comprise less than 2500 mature individuals.
The genus Hylobates is one of the four genera of gibbons. Its name means "forest walker", from the Greek hūlē and bates.
The black crested gibbon is a Critically Endangered species of gibbon found in China, Laos, and northern Vietnam, with four subspecies.
The eastern black crested gibbon, also called Cao-vit black crested gibbon or the Cao-vit crested gibbon, is a Critically Endangered species of gibbon from southeast China and northern Vietnam. The term "Cao-vit" originated from the sounds of their calls or songs that villagers of Ngoc Khe, Phong Nam and Ngoc Con communes of Trung Khanh District, Cao Bang Province of Vietnam use to name for them.
The yellow-cheeked gibbon, also called the golden-cheeked gibbon, the yellow-cheeked crested gibbon, the golden-cheeked crested gibbon, the red-cheeked gibbon, or the buffed-cheeked gibbon, is a species of gibbon native to Vietnam, Laos, and Cambodia. The species was discovered and named after the British naturalist Gabrielle Maud Vassal.
The northern white-cheeked gibbon is a Critically Endangered species of gibbon native to South East Asia.
The wildlife of Laos encompasses the animals and plants found in the Lao People's Democratic Republic, a landlocked country in southeastern Asia. Part of the country is mountainous and much of it is still clad in tropical broadleaf forest. It has a great variety of animal and plant species.
The Hainan black-crested gibbon, also called the Hainan gibbon, is a Critically Endangered species of gibbon found only on Hainan Island, in the Pacific Ocean.
Ficus neriifolia is a species of fig (Ficus). It is native to Asia, including Bhutan, Burma, China, India, and Nepal.
The southern white-cheeked gibbon is a species of gibbon native to Vietnam and Laos. It is closely related to the northern white-cheeked gibbon and the yellow-cheeked gibbon ; it has previously been identified as a subspecies of each of these.
The Yunnan lar gibbon, also known as the Yunnan white-handed gibbon, is a subspecies of the lar gibbon, a primate in the gibbon family, Hylobatidae. This Chinese subspecies is thought to be extinct.
The World's 25 Most Endangered Primates is a list of highly endangered primate species selected and published by the International Union for Conservation of Nature (IUCN) Species Survival Commission (SSC) Primate Specialist Group (PSG), the International Primatological Society (IPS), Global Wildlife Conservation (GWC), and Bristol Zoological Society (BZS). The IUCN/SSC PSG worked with Conservation International (CI) to start the list in 2000, but in 2002, during the 19th Congress of the International Primatological Society, primatologists reviewed and debated the list, resulting in the 2002–2004 revision and the endorsement of the IPS. The publication was a joint project between the three conservation organizations until the 2012–2014 list when BZS was added as a publisher. The 2018–2020 list was the first time Conservation International was not among the publishers, replaced instead by GWC. The list has been revised every two years following the biannual Congress of the IPS. Starting with the 2004–2006 report, the title changed to "Primates in Peril: The World's 25 Most Endangered Primates". That same year, the list began to provide information about each species, including their conservation status and the threats they face in the wild. The species text is written in collaboration with experts from the field, with 60 people contributing to the 2006–2008 report and 85 people contributing to the 2008–2010 report. The 2004–2006 and 2006–2008 reports were published in the IUCN/SSC PSG journal Primate Conservation,, since then they have been published as independent publications.
Kadoorie Conservation China (KCC) is a department under Kadoorie Farm and Botanic Garden, which aims to minimize the loss of biodiversity and promote sustainability in China.
The Tonkin black crested gibbon is a critically endangered subspecies of the black crested gibbon found in Yunnan and Vietnam.
