[3] In Nepal, the Assam macaque occurs east of the Kali Gandaki river at elevations of 200–1,800 m (660–5,910 ft).

[6] During a survey in Nepal's Langtang National Park in 2007, a total of 213 Assamese macaques were encountered in 9 groups in the study area of 113 km2 (44 sq mi).

They preferred maize kernals, followed by potato tubers, but also raided fields with wheat, buckwheat, and millet.

[7] The threats to this species' habitat include selective logging and various forms of anthropogenic development and activities, alien invasives, hunting and trapping for sport, medicine, food, and the pet trade.

For the populations in India, the species is listed under Schedule II, part I of the Indian Wildlife Act.
