Ankasa Conservation Area (National Park and Resource Reserve) is located in the South Western part of Ghana, borderingIvory Coast. The Park is one of the few remnants of undisturbed Tropical Rainforest in Ghana. It was created in 1976. The site is very rich in biodiversity including forest elephants, bongos, leopards, olive colobus, black and white colobus, mangabey and other monkeys, yellow backed duikers and other duikers, pangolins, over 200 species of birds recorded, over 600 species of butterflies etc. The area is one of the known World Bird Areas and a Key Biodiversity Area (Ofori-Amanfo, R. pers. comm. 2023).

The state of Assam is located in northeast India and comprises two global biodiversity hotspots: the Indo-Burma and the Himalayan hotspots (Mazumder 2014). The region is a stronghold for 12 primate species: Bengal slow loris ''Nycticebus bengalensis'', Rhesus macaque ''Macaca mulatta'', Assamese macaque ''Macaca assamensis'', pig-tailed macaque ''Macaca leonina'', stump-tailed macaque ''Macaca arctoides'', Tibetan macaque ''Macaca thibetana'', white-cheeked macaque ''Macaca luecogenys'', capped langur ''Trachypithecus pileatus'', golden langur ''Trachypithecus geei'', Phayre’s langur ''Trachypithecus phayrei'', western hoolock gibbon ''Hoolock hoolock'', and eastern hoolock gibbon ''Hoolock leuconedys'' (Chetry et al. 2021).

In 2009, Chetry et al. (2012) recorded 33 gibbons in 10 groups based on direct sightings in the reserve forests of Hal logaon, Kukurmara, and Kundil Kalia (Chetry et al. 2021). In 2019, 17 individuals in seven groups in these three reserve forests were recorded, indicating a 48.5% population decline. The number of groups was also reduced from 26 (direct observations and call-count) in 2009 to 11 in 2019 (Chetry et al. 2021). In this time frame there was also a 18.75% increase in the proportion of adults to immatures, indicating reduced recruitment and population decline (Chetry et al. 2021).

  • Western hoolock gibbons (Hoolock hoolock) are present in Assam.
  • The population size is unknown.
  • The gibbon population trend is decreasing.
  • The site has a total size of 78,438 km².
  • Key threats to gibbons are habitat encroachment and illegal logging.
  • Conservation activities include education and awareness raising, and supporting communities near forests with alternative income sources such as beekeeping and mushroom cultivation.


Site characteristics

The state of Assam is located in northeast India and comprises two global biodiversity hotspots: the Indo-Burma and the Himalayan hotspots (Mazumder 2014). The region is a stronghold for 12 primate species: Bengal slow loris Nycticebus bengalensis, Rhesus macaque Macaca mulatta, Assamese macaque Macaca assamensis, pig-tailed macaque Macaca leonina, stump-tailed macaque Macaca arctoides, Tibetan macaque Macaca thibetana, white-cheeked macaque Macaca luecogenys, capped langur Trachypithecus pileatus, golden langur Trachypithecus geei, Phayre’s langur Trachypithecus phayrei, western hoolock gibbon Hoolock hoolock, and eastern hoolock gibbon Hoolock leuconedys (Chetry et al. 2021).
