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).

The site is located in the southernmost part of Thailand, in the San Kara Kiri mountain range, bordering Belum Forest Reserve in Malaysia (BirdLife International 2021). The site is part of the Hala-Bala Wildlife Sanctuary, which comprises two non-adjacent sectors: the Bala sector in Narathiwat province, and the Hala sector in Yala province (BirdLife International 2021). Although both siamangs and agile gibbons occur in southern Thailand, the range of siamangs is very small and confined to the Bala Forest (Nongkaew et al. 2018). The Bala Forest is found in a mountain range with an altitudinal range of 100 to 953 m above sea level (Nongkaew et al. 2018). The forest resembles the Malayan mixed dipterocarp forests more than the more seasonal, semi-evergreen forests farther north (Nongkaew et al. 2018).

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).
+
In a 2005 survey, siamangs occurred mostly in the southwestern part of Bala Forest, close to the Malaysian border, while agile gibbons were more evenly distributed throughout the site (Nongkaew et al. 2018).

Habitat encroachment and selective illegal logging represent the most severe threats to gibbons and other wildlife in Assam (Chetry et al. 2021).
+
The expansion of agricultural areas along the border with Malaysia has resulted in loss of forest connectivity between Bala Forest and the forests in Kelantan, Malaysia. Although most of the forest appears to be old-growth, much of the forest was selectively logged before 1990 (Nongkaew et al. 2018). Local people were not found hunting gibbons during a survey of the area in 1995. However, local communities do collect non-timber products such as fruits of Baccaurea spp., Dialium spp., and Garcinia atroviridis species, which are also foods for the apes (Nongkaew et al. 2018). About 9% of people collect these fruits by cutting trees, thus reducing available food sources for the gibbons. It is therefore crucial to reduce the cutting of fruit trees to allow both species to survive in this small area (Nongkaew et al. 2018).

Summary

Loading map...
  • Siamangs (Symphalangus syndactylus) and agile gibbons (Hylobates agilis) are present in Bala Forest.
  • In 2005 it was estimated that 19 groups of siamangs and 136 groups of agile gibbons occur in the site.
  • The population trends are unknown.
  • The site has a total size of 168 km².
  • Key threats to apes are forest fragmentation as a result of agricultural expansion and collection of non-timber products.
  • Conservation activities are not documented.
  • The site is part of the Hala-Bala Wildlife Sanctuary.


Site characteristics

The site is located in the southernmost part of Thailand, in the San Kara Kiri mountain range, bordering Belum Forest Reserve in Malaysia (BirdLife International 2021). The site is part of the Hala-Bala Wildlife Sanctuary, which comprises two non-adjacent sectors: the Bala sector in Narathiwat province, and the Hala sector in Yala province (BirdLife International 2021). Although both siamangs and agile gibbons occur in southern Thailand, the range of siamangs is very small and confined to the Bala Forest (Nongkaew et al. 2018). The Bala Forest is found in a mountain range with an altitudinal range of 100 to 953 m above sea level (Nongkaew et al. 2018). The forest resembles the Malayan mixed dipterocarp forests more than the more seasonal, semi-evergreen forests farther north (Nongkaew et al. 2018).

Ape status

In a 2005 survey, siamangs occurred mostly in the southwestern part of Bala Forest, close to the Malaysian border, while agile gibbons were more evenly distributed throughout the site (Nongkaew et al. 2018).

Threats

The expansion of agricultural areas along the border with Malaysia has resulted in loss of forest connectivity between Bala Forest and the forests in Kelantan, Malaysia. Although most of the forest appears to be old-growth, much of the forest was selectively logged before 1990 (Nongkaew et al. 2018). Local people were not found hunting gibbons during a survey of the area in 1995. However, local communities do collect non-timber products such as fruits of Baccaurea spp., Dialium spp., and Garcinia atroviridis species, which are also foods for the apes (Nongkaew et al. 2018). About 9% of people collect these fruits by cutting trees, thus reducing available food sources for the gibbons. It is therefore crucial to reduce the cutting of fruit trees to allow both species to survive in this small area (Nongkaew et al. 2018).
