The N F Railway authority has extended cooperation to the project. western hoolock gibbons singing are monogamous and live in small family groups (2 - 5 individuals) with the adult male and female and their offspring. The IUCN has classified the population of the western hoolock as endangered and that of the eastern hoolock as vulnerable. News … The work would have been impossible without the efforts of many students and volunteers from the University of Dhaka and Jahangirnagar University. Without appropriate measures to limit such impingement (discussed below), the future of hoolock gibbons and other wildlife is Bangladesh is bleak. … We are also grateful to Anthony Di Fiore and three anonymous reviewers for critically reviewing a previous version of the manuscript and providing suggestions that have significantly improved this manuscript. Binomial name. In Bangladesh both species are critically endangered and distributed mainly in the northeast and southeast hilly regions bordering neighboring India and Myanmar. Geissmann, 1995; Rowe, 1996; Marshall & Sugardjito, 1986). Relative cover = mean basal area per hectare. This species is found particularly east of the Chindwin River in Myanmar and in southwest Yunnan (China). The largest population of hoolock gibbons (84 individuals) occurs in Kaptai (Karnafuli Range) and the second largest population occurs in Lawachara National Park (42 individuals). 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: v35sbm@mun.ca, 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. 2005). Of the two, the western hoolock is listed as Endangered in the IUCN Redlist, while the eastern hoolock is listed as Vulnerable, and both species’ populations have been declining due to habitat destruction of various forms and hunting for meat. Groves 2005). 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.

The efforts for conservation of hoolock gibbon has been funded by US Fish Wildlife Service (Great Ape Conservation Fund). Number of times cited according to CrossRef: Evolution, Ecology and Conservation of Lorises and Pottos. A total of 35 sites were surveyed (Islam et al. The conservation value of degraded forests for agile gibbons Hylobates agilis. Traditionally, the hoolock has been considered being a member of the genus Hylobates and the monotypic representant of a distinct subgenus (e.g. The western hoolock gibbon (Hoolock hoolock) is a globally threatened species, and in Bangladesh it is critically endangered. 2003, Islam et al. To ensure the long-term conservation of the gibbons in this region, ten priority forest complexes have been identified. The Lawachara National Park in Moulvibazar, ... Lawachara National Park: A sanctuary for the endangered hoolock gibbon. Approximately 300 remain in Bangladesh in populations dispersed between isolated forest fragments. Hoolock gibbons (Hoolock hoolock) are endangered small apes occurring in Bangladesh, India, Myanmar, and south China. Currently, hoolocks are categorized by the IUCN World Conservation Union in Bangladesh as critically endangered (IUCN 2000) and globally as endangered (IUCN 2006). If you do not receive an email within 10 minutes, your email address may not be registered, Each region has its distinct tree composition and forest canopy characteristics. We demonstrate that a key habitat feature associated with the survival of hoolock gibbons is edible plant species richness. This study provided the first thorough survey of its population status and distribution in China since its recognition as a new species. The Asian elephant (Elephas maximus) and Hoolock gibbon (Hoolock hoolock) are two globally endan-gered wildlife species limited to only tropical Asian forests. 2006). The western hoolock gibbon (Hoolock hoolock) is a primate from the gibbon family, Hylobatidae. Unfortunately this charismatic species is facing habitat loss and hunting across its range. The endangered forests of Bangladesh: why the process of implementation of the Convention on Biological Diversity is not working, https://doi.org/10.1111/j.1744-7429.2007.00298.x, https://www.cia.gov/cia/publications/factbook/geos/bg.html, *Indicates species that provide food for hoolock gibbons. Islam et al. Feeroz (2001), Ahsan (2001), and Islam et al. The rapid destruction and alteration of habitat (by plantation of exotic monoculture species) that continues in an unplanned manner throughout Bangladesh will undoubtedly result in the extinction of the species. The Forest Department has already developed plans of restoring habitat and boosting hoolock gibbon and other primate populations in Lawachara and Rema Kalenga (FD/MOEF 2000a, FD/MOEF 2000b). The species is probably endangered. (2006) counted the total hoolock gibbon population at each site (a total of 282 hoolock gibbons in 96 groups in 24 of the 35 sites). Lawachara and Kaptai are the two sites in Bangladesh that currently harbor the largest hoolock gibbon populations (Islam et al. For corroboration surveys, field workers walked along 5–25 km of existing trails with a local guide. 1984, Chivers 2001). 2004). The International Union for Conservation of Nature lists the western Hoolock gibbon as Endangered, appearing on the IUCN’s Red List of Threatened Species (IUCN, 2017). Received 11 April 2006; revision accepted 4 October 2006. 2005). Gibbons not only include the most endangered apes but also the most endangered primate species of the world. Ten sites were identified from the northeastern region and 25 sites from the southeastern region (Table 1). However, it’s also edged with sadness – as we’re also calling for the IUCN to immediately confer Endangered status on the Skywalker hoolock gibbon, which faces the same grave and imminent risk to its survival as many other small ape species in southern China … Ahsan (1994, 2001) and Feeroz (2001) have stated the importance of a diversity of fruiting trees in hoolock gibbon survival. Their populations in southern China and Myanmar have not been surveyed in recent years and population estimates from the eighties suggested no more than 200 individuals lived in these areas (MacKinnon & MacKinnon 1987, Mootnick et al. Protection of habitat would require a larger commitment from the government and its Forest Department. The main reasons for this are habitat loss and degradation, hunting and illegal trade. 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. Our study suggests that areas such as Baralekha, Lathitila, Lawachara, Satchari, and Adampur in the northeast and Kaptai, Rampahar, and Bamu have large enough populations and conservation efforts may be directed toward managing these hoolock gibbon populations. In India, it is listed on Schedule 1 of the Indian (Wildlife) Protection Act 1972. Mortality of primates due to roads and power lines in two forest patches in Bangladesh. Fruits and flowers of A. chapalasha constitute an important component of the diet of hoolock gibbons and the higher representation of this species is of great significance to hoolock gibbon persistence in degraded areas (Ahsan 2001, Feeroz 2001, Islam et al. 2004, Molur et al. Wildlife conservation in many Asian and African countries suffers due to a variety of acute social and political problems (Oates 1999, Gain 2002). 2006; Fig. With long and slender arms, hoolock gibbons are swift creatures, barely needing to step on the ground. 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 (CNN) A newly-discovered species of gibbon should be named in honor of Luke Skywalker, say the Star Wars-loving scientists who found it. The species is confined to 29 fragmented forested areas in western and central Java.

We examined the influence of area of natural forests, area of plantations, area of agricultural land and edible plant species richness on the hoolock gibbon numbers from 22 sites in Bangladesh using multiple regression analysis. The IUCN has classified the population of the western hoolock as endangered and that of the eastern hoolock as vulnerable. The hoolock gibbon, an endangered species, is a now rare sight in the forests of northeast India. Unfortunately this charismatic species is facing habitat loss and hunting across its range. Skywalker hoolock gibbon, Hoolock tianxing. Gron KJ. Hoolock gibbons are distributed in various northeastern states in India, with a current total population of more than 2600 individuals (Molur et al. 2008 August 13. The International Union for Conservation of Nature lists the western Hoolock gibbon as Endangered, appearing on the IUCN’s Red List of Threatened Species (IUCN, 2017). Extricating the root cause of population declines in such a variety of factors that influence primate populations is often difficult. 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. 2006). and you may need to create a new Wiley Online Library account. 53 new species should be categorized as Endangered under IUCN criteria.
