Nilgiri Langur
Context:
The Nilgiri langur, often called the "mountain monarch" or guardian of the forests, is facing renewed conservation attention in the Western Ghats.
It is recognized as a flagship species whose survival is tied to the health of montane forests.
Key Characteristics:
It is a black-bodied primate with a distinctive golden-brown mane and amber eyes.
Its slender tail is often longer than its body, aiding balance as it leaps across the canopy
It belongs to the subset of Old World monkeys known as langurs, which are endemic to the Indian subcontinent.
It is sometimes also referred to as the hooded leaf monkey
Behaviour:
A shy, high-canopy dweller that prefers remote habitats with minimal human presence
It lives in small troops led by a dominant male and a few females with their young
The diet is primarily folivorous (leaf-eating), feeding on tender leaves, shoots, flowers, and fruits.
Like other leaf-eaters, it has a multi-chambered stomach to efficiently digest cellulose-rich food
It plays a key role in forest health and regeneration through seed dispersal and vegetation pruning
Habitat and Distribution:
It is endemic to the Western Ghats of southern India
In Kerala it is found in Silent Valley, Wayanad, Periyar, and Agasthyamalai ranges
In Tamil Nadu it is found in Mudumalai, Kalakkad-Mundanthurai, and Mukurthi National Parks, as well as the Nilgiri hills
In Karnataka smaller populations survive in the Brahmagiri and Pushpagiri ranges
Its preferred habitat is evergreen and semi-evergreen forests, as well as shola-grassland mosaics at higher altitudes
Conservation Status & Threats:
IUCN Status:
Classified as Vulnerable on the Red List
Legal Protection:
Listed under Schedule I of the Wildlife (Protection) Act, 1972 (prohibiting hunting with harsh penalties)
Appendix II of CITES
Threats:
Habitat Fragmentation:
Conversion of native forests into tea, coffee, and eucalyptus plantations has broken up their habitat, leaving troops isolated
Poaching:
Historically hunted for its pelt and meat, which was believed by some tribal healers to have medicinal properties (e.g., increasing strength).
While these practices have diminished, sporadic poaching persists
Cultural Significance:
Tribal communities such as the Kattunaikkan, Kurumba, and Muthuvan revere the langur as a forest spirit.
They interpret its loud, echoing calls as omens of rain or warnings of danger.
