Indian Bison (Gaur)

Recently, the population of the Indian Bison in Debrigarh Wildlife Sanctuary has recorded a remarkable increase of 189 individuals within a year, taking the total population to 848. This sharp rise reflects effective conservation management and habitat protection efforts in the sanctuary.

About Indian Bison (Gaur)

The Indian Bison, scientifically known as Bos gaurus, is the largest species of wild cattle in the world and belongs to the family Bovidae. Although commonly referred to as the Indian Bison, its correct name is Gaur.

It is indigenous to South and Southeast Asia and is known for its massive build, muscular body, and distinctive curved horns.

Habitat and Distribution

Gaurs are primarily found in:

• Evergreen and semi-evergreen forests

• Moist deciduous forests with open grasslands

They prefer hilly terrains below 1,500–1,800 meters altitude and thrive in large, undisturbed forest tracts with abundant water availability. Their presence indicates a healthy forest ecosystem.

Conservation Status

The Indian Bison enjoys high legal protection due to its conservation status:

• IUCN Red List: Vulnerable

• CITES: Appendix I

• Wild Life (Protection) Act, 1972: Schedule I

Important Highlight: Being listed under Schedule I of the Wildlife Protection Act, 1972 provides the highest degree of legal protection in India.

Ecological Significance

The Gaur plays a vital ecological role in forest ecosystems.

• It helps maintain vegetation balance through grazing.

• It contributes to seed dispersal, aiding forest regeneration.

• It serves as an important prey species for tigers, supporting predator populations.

Thus, it is considered a keystone species in many forest landscapes.

Major Threats

Despite legal protection, the species faces several challenges:

• Habitat loss and fragmentation due to deforestation and human expansion.

• Disease transmission from domestic cattle, including rinderpest and foot-and-mouth disease.

These threats make continued conservation efforts essential.
