We demonstrate that a key habitat feature associated with the survival of hoolock gibbons is edible plant species richness. Groves 2005). Hoolock gibbons (Hoolock hoolock Harlan, 1834) are endangered (A4acd ver3.1) small apes occurring in Bangladesh, India, Myanmar, and south China. The IUCN has classified the population of the western hoolock as endangered and that of the eastern hoolock as vulnerable. The species’ populations have been declining due to habitat destruction of various forms and hunting for meat. In fact, the areas that have undergone declines in population have also lost considerable natural forests as classified by the Forest Department. For corroboration surveys, field workers walked along 5–25 km of existing trails with a local guide. The main reasons for this are habitat loss and degradation, hunting and illegal trade. Gibbons (hylobatidae) are small apes distributed in south and southeast Asia (Preuschoft et al. The western hoolock gibbon (Hoolock hoolock) is a globally threatened species, and in Bangladesh it is critically endangered. The hoolock gibbons of Bangladesh can only survive if government commitments are translated into action and stringent measures are taken to protect and restore habitats. Lawachara and Kaptai are the two sites in Bangladesh that currently harbor the largest hoolock gibbon populations (Islam et al. The hoolock gibbons, also known as hoolocks, one of the most important attractions of north east india’s wildlife, hoolock gibbons are two primate species from the family of the gibbons. The discovery 54 of the new species focuses attention on the need for improved conservation of small 55 apes, many of which are in danger of extinction in southern China and Southeast Asia. If you do not receive an email within 10 minutes, your email address may not be registered, All hoolock gibbons in each site were located and counted. This species is found particularly east of the Chindwin River in Myanmar and in southwest Yunnan (China). Shillong, Sept. 22: In a major boost to wildlife conservation, a western hoolock gibbon, a highly endangered species, was born at the Huro Programme Rehabilitation Centre in Meghalaya's West Garo Hills this week. The efforts for conservation of hoolock gibbon has been funded by US Fish Wildlife Service (Great Ape Conservation Fund). Most of these sites fall under the jurisdiction of different forest divisions and have undergone extensive deforestation and habitat alteration over the last two decades (Gain 2002). Gron KJ. We presented the result of a systematic survey on the population size and distribution of the Endangered Gaoligong hoolock gibbon (Hoolock tianxing) in Houqiao Town, Tengchong City, Yunnan Province of China.A total of 15–18 individuals of H. tianxing in 5–6 gibbon groups and one solitary gibbon were recorded during the survey conducted in November 2019. 2008 August 13. J Trop Ecol 7(1):147-53. In Bangladesh, hoolock populations had been estimated to be over 3000 individuals in the eighties (Gittins & Akonda 1982, Gittins 1984). This study determined that one such factor is most likely an important cause of population declines of hoolock gibbons in Bangladesh. The eastern hoolock gibbon (Hoolock leuconedys) male can be differentiated from the western species (Hoolock hoolock) by its grizzled silver coloured chest; a silver genital tuft and the white brow streaks are widely separated in adult males and juveniles of both sexes instead of being We compiled a list of all the plant species whose leaves, shoots, fruits, flowers are reported to be eaten by hoolock gibbons from Islam and Feeroz (1992), Ahsan (1994), and FD/MOEF (2000a). Key to the conservation of hoolock gibbons in these and other areas will be habitat protection. Habitat quality across sites.— Maps of each study site were collected from the digitized map database available in the Forest Department, Ministry of Environment and Forest. This is critical in not only understanding the ecology of this endangered species, but also for developing conservation and management plans, given limited resources and habitat and high human population pressure in Bangladesh. 81/Ka, Road # 11, Baridhara, Dhaka 1212, Bangladesh, Corresponding author; Current address: Department of Biology, Memorial University of Newfoundland, St. John's, Newfoundland, Canada A1B 3X9; e‐mail: firstname.lastname@example.org, Current address: Wildlife Trust of Bangladesh, 69/1 New Circular Road, Malibagh, Dhaka, Bangladesh, Department of Zoology, University of Dhaka, Dhaka 1000, Bangladesh, Department of Zoology, Jahangirnagar University, Savaar, Dhaka, Bangladesh.
