Data Deficient in Bangladesh (IUCN Bangladesh 2000).

This species has been categorized as Critically Endangered in view of the number of mature individuals being less than 250 and population decline is continuing due to habitat destruction. Also its populations are heavily fragmented and there is very little or no genetic exchanges between two neighbouring populations. Severe human-elephant conflict and poaching are also contributing to this population decline.

This species has been categorized as Endangered in view of the decline in of 50% of its Extent of Occurrence and Area of Occupancy and habitat quality over three generations. Moreover, there exist less than 250 individuals in each subpopulation.

This species is listed as Critically Endangered as its population has declined more than 80% over the last three generations due to habitat destruction. Moreover, the mature individuals in each subpopulation are less than 50.

The population of this species is known to have been decreased. Although, Gittins and Akonda (1982) estimated only 100 individuals in Bangladesh. Khan 1987 considered the total population of Hanuman in Bangladesh to be between 250 and 300 individuals considering all ages. Khan and Ahsan (1986) reported 89 individuals in 8 groups in Jessore. Khatun (2012) reported 246 individuals at six villages of Keshabpur under Jessore District. Currently, approximately 204 individuals have been observed in at 11 groups distributed in Keshabpur and Monirampur Upazilas under the same district (Anon 2015, unpublished report), though the total population is not more than 250 individuals occurring in all districts. The number of mature individuals in total population could be slightly more than 140. The Extent of Occurrence of this species is more than 100 km2 but below 5,000 km2. Actual Area of Occupancy is above 10 km2. Since male migration has been occurring, all groups together can be considered as single population.

This species has a restricted distribution only in the mixed evergreen forests of northeast, east and southeast of the country. So, it is inferred that at least 50% of its population has been reduced due to the decline of its AOO, EOO, over the last two decades or so, unprecedented changes in habitat qualities and potential level of exploitation that are continuing unabated. It has been wiped out from its former range in the Sal forests (Khan 1987). Thus, it has been categorized as Endangered.

Though this species has a wide distribution in forested areas and also in some human settlements, its population is declining. Total number of mature individuals is less than 10000 and number of mature individuals in each subpopulation is less than 1000. So, it fulfills the criteria for threatened category Vulnerable.

This species is restricted to some fragmented patches of mixed evergreen forests and population size is below the threshhold level of Endangered category. Due to the adverse effects on Area of Occupancy and Extent of Occurrence, quality of habitat, restricted number of locations and an insignificant number of mature individuals, it qualifies for Endangered.

This species qualifies Critically Endangered criteria because of population reduction observed more than 90% over three generations and continuing (Khan 1981, 1987, Khan and Wahab1983, Feeroz 2001, Hasan and Feeroz 2010). Its EOO and AOO are less than the threshold level. Number of mature individuals is less than 20. Found only in two locations.

This species has been recorded only from three locations; one in the northeast and the remaining two in the southeast. Its Extent of Occurrence, Area of Occupancy and habitat quality have been declining and presently occupying Extent of Occurrence and Area of Occupancy are within the threshold of Endangered category (Khan 1981, 1985, 1987, 2015, Gittins and Akonda 1982, Feeroz et al. 1995, Feeroz 2001, Khan and Ahsan 1986).
