The 28-day survey was carried out in May and June 2002 in the Doom-dooma, Dibrugarh, Digboi and Tinsukia Forest Divisions of Upper Assam. Seventeen protected areas in south-east Thailand were surveyed for the Endangered pileated gibbon Hylobates pileatus during April 2004–March 2005, with the objectives of establishing the species’ current distribution, obtaining approximate population estimates for the largest forest areas, and assessing threats to the species’ survival. 1984; Leighton 1987). The western hoolock gibbon (Hoolock hoolock) is a higher primate found in india. Workshop Report, 2005 Abstract: A survey on the present distribution, population status and conservation of Western Hoolock Gibbon (Hoolock hoolock) was conducted from September 2006 to April 2007 in Namdapha National Park, Arunachal Pradesh, northeastern India. There are two species: the western hoolock gibbon (Hoolock hoolock) and the eastern hoolock gibbon (Hoolock leuconedys) (Mootnick and Groves 2005; Das et al. In a census in 2007, only 62 individuals in 17 groups were found in Lawachara and in the greater West Bhanugach Reserved Forest. Encounter rates were used as an index of gibbon population densities, and gibbon group size and age class ratios as an index of the status of the population. This species is found particularly east of the Chindwin River in Myanmar and in southwest Yunnan (China). Reports of several other surveys in southern Myanmar are pending (Geissmann et al. The western Hoolock gibbon is listed on t he Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) Appendix I and on schedule I of the Indian Wildlife Protection Act of 1972. POPULATION: The global population of this species is estimated to be <3000 individuals, with India possessing the vast majority (2600). In India, it is listed on Schedule 1 of the Indian (Wildlife) Protection Act 1972. Far from the madding crowd, in the western part of Arunachal lies the last remnants of a rainforest patch, rich in biodiversity. A status survey was done in the Longai Reserve Forest from June 2012 to … The Western Hoolock Gibbon, the only wild ape found in India and also among the most endangered primates in the world, has found a safe haven thanks to the people of Meghalaya. Until 2007, the global population of Hoolock gibbons was estimated at fewer than 5,000 individuals. Most populations of the western hoolock are isolated and small, with 80% of those assessed in India and Bangladesh harbouring fewer than 20 individuals, and over half having fewer than 10 (Walker et al. An estimated 90 percent of its population has been lost over the past 30 years due to deforestation, hunting, and government neglect. Populations of western hoolock gibbons have declined by almost 90% over the last 30 years, and it is now considered to be one of the most endangered 25 primate species in the world. 2007). Myanmar retains a relatively large area of intact habitat with the Hoolock’s range, and holds populations of the distinct Eastern and Western Hoolock gibbon. Western hoolock gibbon (Hoolock hoolock) is listed as an endangered mammal in IUCN Red List. The southernmost population of the western hoolock gibbon in Myanmar has been surveyed by Geissmann et al. Indian records of the species likely to actually represent the Western Hoolock The species has experienced a drastic population decline in the last 30 to […] The Western hoolock gibbon (Hoolock hoolock) a top canopy ape species occurs in the forests of Northeastern India. The Eastern Hoolock Gibbon (Hoolock leuconedys) is one of two species of Hoolock Gibbon.
This is Mehao WLS and the habitat of Eastern Hoolock Gibbon - … It is one of the top 25 most endangered primates and one of the six non-human primate species found in Lawachara. There may be much yet to learn … However, in many publications, the two species are only considered distinct at the subspecific level.
A western hoolock gibbon. Hoolock gibbons have been placed within their own genus, Hoolock, as well as split into two discrete species, the western hoolock gibbon (H. hoolock) and the eastern hoolock (H. leuconedys) (Mootnick & Groves 2005).
2006).They are confined to the rain forests of Southeast Asia, Northeast India, and Bangladesh (Preuschoft et al. The arboreal species is so reluctant to spend time on the ground that even the loss of a single connecting tree can render forest fragments inaccessible to them. Hoolock gibbons are the only apes found in India. The data were re corded from 12
2008). The western hoolock gibbon is threatened globally, too.
Conservationists say the future of the IUCN-listed endangered species is very much in jeopardy. Conservation of Western Hoolock Gibbon (Hoolock hoolock hoolock) in India and Bangladesh - Population and Habitat Viability Assessment (P.H.V.A.) It is also listed in CITES Appendix I and in the Schedule I of the Indian Wildlife (Protection) Act, 1972. Introduction.
