• Himalayan Gray Langurs (Semnopithecus ajax) are also called the Chamban Langurs or Chamba Sacred Langurs.
  • The Gray Langur was once considered a sub-species of the Semnopithecus entellus, commonly known as the Bengal Sacred Langur or Hanuman Langur, but it was separated as a species in 2005.
  • They are colobine i.e they are leaf-eating animals. They also eats seeds, flowers, buds, bark and insects, including caterpillars. 
  • They are also called the Kashmir gray langur.
  • It is grey washed with buff or silvery shades. Their hands and feet are black and they have long tails for balancing on tree limbs.
  • Habitat:
    • It is found both in forests and near human habitations.
    • These species live at an elevation of 2200-4000 m above sea level. 
    • Their population is mostly concentrated in the subtropical, tropical moist, temperate, alpine, coniferous and broadleaf forests. 
    • he Himalayan Grey Langur is present in a particular area only during some parts of the year.
    • They change their locality during different seasons, depending upon the availability of food and environmental conditions.
  • Distribution:
    • It is distributed in a varied habitat including dry savannah and tropical rainforests.
    • In the Indian Subcontinent, their distribution is reported in the Chamba district of western Himachal Pradesh, south to the Tapti River and the Krishna River, Bhutanand Nepal.
  • Threat:
    • The Himalayan grey langur is facing threats from multiple factors such as: 
      • Fragmentation,
      • Deforestation,
      • Persecution and retaliatory killing due to crop destruction, and
      • Commercial horticulture expansion.
      • Mining and Pollution.
  • Protection Status:
    • Protected under Schedule II of the Wildlife Protection Act, 1972
    • IUCN Red List: Least Concern
    • CITES: Appendix-I
    • The two protected areas: Machiara National Park and the Dachigam National Park

Steps for Conservation

  • The Himalayan langur project was started by a Biological Anthropologist in 2014 Dr. Himani Nautiyal with the following objectives:
    • Provide local people with knowledge of the Chamba Sacred Langur and its habitat.
    • Develop positive attitudes towards the conservation of the species and nature.
    • Encourage people to enact environment-friendly behaviours. 

A recent study has concluded that altitude plays an important role in deciding the food habits of the Himalayan Gray Langur.
