The Debrigarh Wildlife Sanctuary in Odisha is set to host the second edition of the “Indian Bison Fest”, a conservation and eco-tourism initiative aimed at highlighting the sanctuary’s biodiversity and raising awareness about the protection of the Indian bison (Gaur). The event also seeks to promote community participation and sustainable tourism in the region.

Debrigarh Wildlife Sanctuary

Location and Geographical Features

• Debrigarh Wildlife Sanctuary is located in Bargarh district of Odisha, near the famous Hirakud Dam on the Mahanadi River. Hirakud Dam is notable for being the longest earthen dam in the world and one of the longest dams in India.
• The sanctuary forms part of the Hirakud reservoir ecosystem, which supports diverse flora and fauna as well as seasonal migratory birds.

Historical Significance

• The sanctuary holds historical importance due to its association with Veer Surendra Sai, a prominent freedom fighter from Odisha who led resistance against British rule. During the rebellion, his operational base at Barapathara was located within the present sanctuary area.

Ecological Characteristics

• Vegetation: The sanctuary is dominated by mixed and dry deciduous forests. Major plant species include: Sal, Asana, Bija, Amla, Dhaura. These forests provide suitable habitats for several large mammals and birds.
• Faunal Diversity: Debrigarh Wildlife Sanctuary hosts a rich variety of wildlife, including: Indian leopard, Sloth bear, Chousingha (four-horned antelope), Sambar deer, Gaur (Indian bison), Wild boar, Dhole (Indian wild dog). The sanctuary is also an important wintering ground for migratory birds. Common bird species include: Crested serpent eagle, Flowerpeckers, Red-vented bulbul, Tree pie, Drongo, Oriental white-eye

Indian Bison (Gaur)

General Characteristics

Gaur, commonly known as the Indian bison, is the largest species among wild cattle belonging to the Bovidae family. It is characterized by:

• a massive and muscular body,
• a prominent grey ridge on the forehead between the horns,
• large horns that curve upward from the sides of the head.

Distribution: Gaurs are indigenous to South and Southeast Asia, with significant populations found in India’s forested regions.

Habitat

They typically inhabit:

• evergreen and semi-evergreen forests
• moist deciduous forests
• forest landscapes with open grasslands and abundant water sources

Gaurs generally prefer hilly terrains below 1,500–1,800 metres altitude with large undisturbed forest tracts.

Conservation Status

According to the International Union for Conservation of Nature (IUCN):

• Status: Vulnerable

Major threats include habitat fragmentation, disease transmission from livestock, and human-wildlife conflict.

Odisha’s Debrigarh Wildlife Sanctuary has recently been approved by the National Tiger Conservation Authority (NTCA) to become India’s newest tiger reserve. This marks a significant ecological achievement rooted in community participation, innovative eco-tourism, and conservation success.

Location and Geography

• Situated in western Odisha, near Sambalpur and Bargarh district, Debrigarh is bordered by the Hirakud Reservoir—a Ramsar-tagged wetland and part of the Mahanadi River system.
• The Hirakud Dam, the world’s longest earthen dam, lies adjacent to the sanctuary.
• Spread over 804 sq km, it includes around 347 sq km of core area, encompassing forests, grasslands, and wetlands, making it a unique amphi-terrestrial ecosystem.

Historical Significance

• The rugged terrain of Debrigarh was a strategic base for freedom fighter Veer Surendra Sai during his armed resistance against British colonial rule.
• Sites like Bara Bakra/Barapathara remain important heritage landmarks within the sanctuary.

Flora and Fauna

• Vegetation: Dominated by mixed and dry deciduous forests, with species such as Sal, Asana, Bija, Aanla, and Dhaura.
• Mammals: Indian bison (gaur), sambar deer, wild boar, chousingha (four-horned antelope), leopards, sloth bears, and wild dogs.
• Avifauna: Over 300 bird species, including 120 migratory species such as crested serpent eagle, drongo, tree pie, flower peckers, and white-eye oriental.

Eco-Tourism and Innovation

• Debrigarh is home to India’s first dark sky tourism hub, offering stargazing facilities.
• Adventure tourism includes safaris (53 vehicles), kayaking, cycling, and birding trails, designed with minimal ecological footprint.

Conservation and Community Model

• Declared a sanctuary in 1985 and upgraded to a tiger reserve in 2025.
• A community-led model: Over 400 families voluntarily relocated with rehabilitation packages; 155 villages actively participate in conservation and eco-tourism activities.
• Wildlife success: Expansion of prey base, increase in gaur population, and nearly 40% of herds comprising newborns, reflecting ecosystem recovery.

Significance

Debrigarh exemplifies a national model of integrated conservation, blending:

• Biodiversity protection (tiger reserve status, prey base recovery).
• Cultural heritage (legacy of Veer Surendra Sai).
• Sustainable eco-tourism (dark sky hub, water- and land-based safaris).
• Community participation (relocation and livelihood integration).

Its success offers a replicable blueprint for wildlife conservation across India, highlighting how ecological protection, heritage, and rural livelihoods can be balanced under one framework.
