This species is widely but thinly distributed in the Sal and mixed evergreen forests of the country (Khan 1987, 2015). Its EOO and AOO are much larger than the threshold level. As it is a forest dwelling species, its habitat is continuously shrinking and being degraded due to faulty forestry policies, practices and lumber poaching. On these bases, it has been assessed as Near Threatened.

This species is rare and occurs in and around mixed evergreen forests of Greater Sylhet in the northeast. Both EOO and AOO of this species are relatively small and restricted to a few forest patches. Continuing decline of the quality of its known and potential habitats has been observed. Therefore, it qualifies for Endangered category.

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have been observed in at 11 groups distributed in Keshabpur and Monirampur Upazilas under the same district (Anon 2015, unpublished report), though the total population is not more than 250 individuals occurring in all districts.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.

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.
