Wildlife Sanctuary in India — Legal Framework, Major Sanctuaries & UPSC Guide

India is one of the 17 mega-diverse countries in the world, home to roughly 7-8% of all recorded species despite occupying only 2.4% of the global land area. The wildlife sanctuary is one of the primary instruments through which this biodiversity is legally protected. Understanding how sanctuaries are constituted, governed, and differentiated from other protected areas is essential for UPSC aspirants across Prelims, Mains, and even the interview stage.

What Is a Wildlife Sanctuary?

A wildlife sanctuary is a protected area declared by a state government under Chapter IV of the Wildlife Protection Act, 1972 for the purpose of protecting, propagating, or developing wildlife and its environment. The Chief Wildlife Warden of the state is the administrative authority.

Key legal characteristics:

• Declared under Section 26A of the Wildlife Protection Act, 1972.
• Human activities are regulated but not entirely prohibited. Limited activities such as grazing, movement through the area, and collection of forest produce may be permitted with the approval of the Chief Wildlife Warden.
• Private ownership of land is allowed in certain cases, unlike national parks.
• The boundaries can be altered by the state government.
• Hunting is prohibited, except under special orders from the Chief Wildlife Warden for reasons such as scientific research, population management, or education.

Wildlife Sanctuary vs National Park vs Biosphere Reserve

This is one of the most frequently tested distinctions in UPSC Prelims. The table below summarises the key differences.

Key Prelims fact: A national park can exist within a biosphere reserve, and a wildlife sanctuary can be upgraded to a national park, but the reverse is not possible without a complex legal process.

IUCN Protected Area Categories

The International Union for Conservation of Nature (IUCN) classifies protected areas into six categories. Indian wildlife sanctuaries broadly correspond to Category IV: Habitat/Species Management Area, though some may overlap with other categories depending on management objectives.

Major Wildlife Sanctuaries in India — State-Wise

India has over 567 wildlife sanctuaries. Below is a selection of the most important ones frequently appearing in UPSC examinations.

Governance and Administration

The governance structure for wildlife sanctuaries involves multiple levels:

1. National Board for Wildlife (NBWL): Chaired by the Prime Minister, this is the apex advisory body on wildlife conservation. Any project involving diversion of land from a sanctuary requires NBWL clearance.
2. State Board for Wildlife: Chaired by the Chief Minister, this body advises the state government on wildlife matters.
3. Chief Wildlife Warden: The principal officer responsible for administering sanctuaries within a state.
4. Advisory Committee: Each sanctuary has an advisory committee constituted under Section 33B of the Wildlife Protection Act.

Recent developments: The 2022 amendment to the Wildlife Protection Act brought significant changes, including better regulation of trade in specimens, alignment with CITES, and stricter penalties. The amendment also introduced new schedules for species classification, replacing the earlier six-schedule system with four schedules.

Conservation Challenges

Wildlife sanctuaries in India face several persistent challenges:

• Human-wildlife conflict: Encroachment, crop raiding, and retaliatory killings remain widespread, especially around sanctuaries near agricultural land.
• Encroachment and land-use change: Unlike national parks, the provision for private land ownership within sanctuaries creates ongoing disputes.
• Poaching: Despite strict laws, illegal hunting and trade in wildlife products continue, particularly for tigers, rhinos, and pangolins.
• Infrastructure projects: Linear infrastructure such as highways and railways through or near sanctuaries fragments habitats. The NBWL clearance process is often criticised for being either too lenient or too slow.
• Invasive species: Lantana camara and Prosopis juliflora are among the invasive plants severely degrading habitats in many sanctuaries.

Important Constitutional and Legal Provisions

• Article 48A (DPSP): The State shall endeavour to protect and improve the environment and safeguard forests and wildlife.
• Article 51A(g) (Fundamental Duty): It is the duty of every citizen to protect and improve the natural environment including forests, lakes, rivers, and wildlife.
• Schedule VII: Forests and wildlife fall under the Concurrent List (Entry 17A and 17B, added by the 42nd Amendment, 1976).
• Environment Protection Act, 1986: Provides an umbrella framework for environmental governance.
• Forest Conservation Act, 1980 (amended 2023): Regulates diversion of forest land for non-forest purposes.
