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).

Chimpanzees are extinct or nearly extinct in Ala Forest Reserve. During a 2006 survey, no chimpanzees, nor signs of chimpanzees, were encountered (Greengrass 2006).
+
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).

The northern half of the reserve is dominated by teak, oil palm, and cocoa plantations (Greengrass 2006). In the southern half of the reserve, even though the forest seems to be in a better condition, logging pressure is very high and large mammals are very scarce (Greengrass 2006).
+
Habitat encroachment and selective illegal logging represent the most severe threats to gibbons and other wildlife in Assam (Chetry et al. 2021).

As part of a study on the exposure of African great ape sites to climate change impacts, Kiribou et al. (2024) extracted climate data and data on projected extreme climate impact events for the site. Climatological characteristics were derived from observation-based climate data provided by the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP, www.isimip.org). Parameters were calculated as the average across each 30-year period. For 1981-2010, the EWEMBI dataset from ISIMIP2a was used. For the two future periods (2021-2050 and 2071-2099) ISIMIP2b climate data based on four CMIP5 global climate models were used. For future projections, two Representative Concentration Pathways (RCP) were used. RCP 2.6 is a scenario with strong mitigation measures in which global temperatures would likely rise below 2°C. RCP 6.0 is a scenario with medium emissions in which global temperatures would likely rise up to 3°C by 2100. For the number of days with heavy precipitation events, the 98th percentile of all precipitation days (>1mm/d) was calculated for the 1979-2013 reference period as a threshold for a heavy precipitation event. Then, for each year, the number of days above that threshold was derived. The figures on temperature and precipitation anomaly show the deviation from the mean temperature and mean precipitation for the 1979-2013 reference period.
 
  
−
The estimated exposure to future extreme climate impact events (crop failure, drought, river flood, wildfire, tropical cyclone, and heatwave) is based on a published dataset by Lange et al. 2020 derived from ISIMIP2b data. The same global climate models and RCPs as described above were used. Within each 30-year period, the number of years with an extreme event and the average proportion of the site affected were calculated (Kiribou et al. 2024).

Summary

Loading map...
  • 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).

Ape status

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).

Threats

Habitat encroachment and selective illegal logging represent the most severe threats to gibbons and other wildlife in Assam (Chetry et al. 2021).

Table 3. Threats to apes in Assam

Category Specific threats Threat level Description Year of threat
1 Residential & commercial development 1.1 Residential areas High Habitat encroachment due to development activities and expansion of human settlements (Chetry et al. 2021, Chetry pers. comm. 2023). Ongoing (2023)
2 Agriculture & aquaculture 2.1 Annual & perennial non-timber crops High Encroachment due to expansion of land for agriculture, including ginger and orange cultivation (Chetry et al. 2021, Chetry pers. comm. 2023).

Challenges

Lack of long-term funding for continuity of conservation activities and lack of a national gibbon action plan, which exists for other endangered species in the country, but not for gibbons (Chetry pers. comm. 2023).

Research activities

Multiple studies have been conducted in Assam to investigate the status of gibbons and other primates present in the area (Chetry et al. 2021, Kakati et al. 2009, Choudhury 2009, Sarma et al. 2021).
