Wildlife sanctuaries

1. Meaning, purpose and ecological importance

A wildlife sanctuary protects an area of ecological, faunal, floral, geomorphological, natural or zoological significance for conserving wildlife and its environment. It is an area-based legal instrument, not simply a place where hunting is prohibited. Forests, grasslands, wetlands, deserts, rivers and coastal or marine habitats can all receive sanctuary protection. The presence of a charismatic mammal is therefore not a prerequisite.

Sanctuaries conserve breeding grounds, feeding areas, nesting sites and seasonal refuges. They can also connect larger protected landscapes, allowing dispersal and maintaining genetic exchange between wildlife populations. Their ecosystem services include water regulation, soil protection, carbon storage and support for pollination. However, a sanctuary boundary does not necessarily encompass the full range of a migratory or wide-ranging species; conservation also depends on surrounding land use.

Indian examples illustrate this diversity: the National Chambal Sanctuary protects riverine habitat important for gharials and Gangetic dolphins; Gahirmatha Marine Wildlife Sanctuary protects coastal waters associated with olive ridley turtles; and the Indian Wild Ass Sanctuary in Gujarat protects the saline desert landscape of the Little Rann of Kutch. A 'bird sanctuary' is generally a sanctuary named for its conservation focus, not a separate statutory category.

• Study sanctuaries through a location–habitat–species linkage rather than memorising names alone.
• Legal protection does not automatically guarantee effective conservation: staffing, ecological connectivity and control of external pressures remain essential.

2. Declaration, rights and boundaries

Under Section 18, a State Government may notify its intention to constitute an eligible area as a sanctuary. The notification describes the area's situation and limits. The Collector then investigates the existence, nature and extent of rights over land within the proposed sanctuary. The Act provides a separate declaration route under Section 26A for reserve forests and territorial waters, so the ordinary rights-settlement sequence should not be mechanically applied to every sanctuary.

Where rights are established, the statutory options include excluding the relevant land, acquiring the land or rights through the applicable legal process, or allowing specified rights to continue in consultation with the Chief Wild Life Warden. Once the required proceedings are completed, a final notification under Section 26A specifies the sanctuary and its boundaries. Important protective provisions apply from the initial notification stage under Section 18A; protection does not necessarily wait until final declaration.

Inclusion of territorial waters requires the prior concurrence of the Central Government. The Act also protects the occupational interests of local fishermen and recognises innocent passage of vessels in accordance with its provisions. Alteration of sanctuary boundaries requires a recommendation of the National Board for Wild Life. A local administrative decision or a change in a management plan is not sufficient.

The Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006 is also relevant wherever applicable. Recognition of forest rights and the safeguards governing relocation must be respected. Sanctuary declaration should not be equated with automatic eviction. Critical wildlife habitat under the Forest Rights Act is a distinct legal concept, not another name for every sanctuary or for a tiger reserve's critical tiger habitat.

• Prelims distinction: initial intention notification, rights settlement and final declaration are separate legal stages.
• Do not confuse the National Board for Wild Life with the State Board for Wild Life when studying boundary alteration.

3. Management and permissible activities

The Chief Wild Life Warden is the principal statutory authority for controlling, managing and maintaining sanctuaries. Management includes habitat improvement, protection against fire and poaching, maintenance of ecological conditions and regulation of activities. Sanctuary management must follow the applicable statutory requirements and management plan; the designation is not a blanket permission for commercial use.

Entry is regulated, but sanctuaries are not closed to everyone. The Act recognises specified categories, including public servants on duty, persons permitted to reside within a sanctuary and persons holding rights over immovable property there. Permits may be granted for purposes such as wildlife study, photography, scientific research, tourism and lawful business with residents. Entry permission does not authorise hunting, collection of specimens or habitat damage.

Section 29 restricts destruction, exploitation or removal of wildlife, including forest produce, habitat damage and changes to water flows into or out of a sanctuary. Any legally permissible exception must meet the Act's substantive conditions and approval process. Hunting is generally prohibited, subject to narrowly defined statutory exceptions; calling an activity 'traditional' or 'touristic' does not automatically legalise it.

Grazing and livestock movement may be regulated, controlled or prohibited in the interests of wildlife. Thus, 'grazing is always allowed in sanctuaries' is incorrect. Fire-setting that endangers a sanctuary, unauthorised entry with weapons and use of injurious chemicals are also restricted. Livestock disease prevention is important because disease transmission can occur where domestic animals and wildlife share habitat.

• Tourism is a regulated activity, not an unrestricted right.
• Local rights may continue, but their existence does not remove wildlife-protection obligations.
• Infrastructure proposals must satisfy all applicable wildlife, forest and environmental requirements; one clearance does not automatically replace another.

4. Distinguishing related conservation designations

National parks and wildlife sanctuaries both provide strong statutory protection under the 1972 Act. National parks have stricter rules on continuation of land rights and grazing. However, describing sanctuaries as areas where all human activities are allowed is misleading. Both categories restrict hunting and habitat destruction, and both require the National Board for Wild Life's recommendation for boundary alteration.

Conservation reserves generally protect government-owned land, particularly areas adjoining protected areas or linking them, after consultation with local communities. Community reserves protect eligible private or community land where an individual or community volunteers for conservation. Despite the similar terminology, neither category is legally interchangeable with a wildlife sanctuary.

A biosphere reserve is a broader conservation and sustainable-development designation that can contain sanctuaries and national parks. Ramsar designation identifies internationally important wetlands but does not itself create a sanctuary under the wildlife law. Eco-sensitive zones are notified under the Environment (Protection) Act, 1986 framework around protected areas to regulate specified activities. Their applicable extent and restrictions must be checked against relevant notifications and judicial directions rather than assumed to be identical everywhere.

• A tiger reserve may overlap a sanctuary or national park, but tiger reserve status is a distinct legal designation.
• A protected area's current category matters: historical names may survive after an upgrade or renotification.

5. Conservation challenges and examination approach

Major threats include encroachment, illegal hunting, invasive alien species, mining, pollution, altered river flows and fragmentation by roads or other infrastructure. Wetland sanctuaries may be damaged by activities far upstream, while marine sanctuaries depend on fisheries management beyond their boundaries. Climate change can alter water availability, vegetation and species distribution, making landscape-level planning increasingly important.

Effective management combines scientific monitoring, habitat restoration, anti-poaching measures and cooperation with neighbouring communities. Timely compensation for wildlife damage, equitable livelihood opportunities and participation in planning can reduce conflict. Relocation, where legally justified and necessary, requires applicable rights-based safeguards; it should not be treated as the default solution.

For Prelims, revise the State or Union Territory, physiographic setting, river or coast, representative species and legal category of major sanctuaries. Read absolute statements carefully: words such as 'only', 'all', 'automatically' and 'completely prohibited' often obscure the distinction between a general prohibition, a regulated activity and a statutory exception.

• Prioritise official notifications and current State Forest Department information when a site's name or status changes.
• Use time-stamped official figures for sanctuary counts and area because new notifications and boundary changes affect totals.
