Manas Wildlife Sanctuary, Assam

Historical Context & Location

Manas Wildlife Sanctuary is situated in the foothills of the Eastern Himalayas in Assam, along the India-Bhutan border. Named after the Manas River and the serpent goddess Manasa, the sanctuary spans over 500 sq km and forms part of the core zone of the Manas Tiger Reserve.

Declared a UNESCO World Heritage Site in 1985, Manas is notable for its rich biodiversity and ecological significance. It is also a Biosphere Reserve, an Elephant Reserve, and a Project Tiger Reserve — making it one of the most protected conservation zones in India.

Key Habitats and Fauna

Unique Ecosystems
Manas comprises alluvial grasslands, moist deciduous forests, and semi-evergreen forests. These support a rich variety of flora and fauna, including endemic and endangered species.
Endangered Wildlife
The sanctuary is home to iconic species such as the Bengal tiger, Indian one-horned rhinoceros, Asian elephant, golden langur, hispid hare, and pygmy hog. It shelters over 60 mammal species, 450 bird species, and several reptiles and amphibians.
Riverine Landscape
The Manas River and its tributaries shape the park's terrain and serve as lifelines for its ecosystems. The river creates fertile floodplains and provides vital water for flora and fauna.

Cultural and Transboundary Significance

Manas shares its northern boundary with Bhutan’s Royal Manas National Park, forming a transboundary conservation area that allows genetic flow and wildlife migration. This partnership enhances species survival and habitat connectivity.

The sanctuary holds spiritual and cultural importance for local communities such as the Bodo tribe, who regard the forest as sacred. These communities are now engaged in conservation activities, blending traditional knowledge with modern science.

UNESCO inscribed Manas under criteria (vii), (ix), and (x) for its natural beauty, ecological processes, and biodiversity richness.

It exemplifies the Himalayan foothill ecosystem with high species diversity.
It serves as a genetic corridor linking Indian and Bhutanese protected areas.
Manas is a symbol of successful restoration following past political conflict and poaching.

Conservation

The sanctuary faced threats during civil unrest in the 1980s–90s, leading to wildlife decline. Since then, concerted efforts by the government, NGOs, and local communities have led to remarkable recovery. Current initiatives include anti-poaching patrols, eco-tourism, habitat restoration, and species reintroduction. Continuous monitoring and education programs aim to secure the sanctuary’s future for both wildlife and people.
