Difference between National Parks and Wildlife Sanctuaries with features and objectives

National Parks and Wildlife Sanctuaries are Government-declared protected areas with the primary objective of protecting biodiversity, saving flora and fauna, and restoring natural ecological balance. Spectacular natural beauty in India's national parks and wildlife sanctuaries attracts millions of tourists every year. There are a few basic distinctions between national parks and sanctuaries.


What is a National Park?

The Government may designate an area of adequate ecological, geo-morphological and natural significance as a national park. There are no human activities permitted while tourism is allowed within the park in some areas. The harvesting of forest resources and the grazing of animals are strictly forbidden. These practices can be carried out by wildlife authorities in coordination with the National or State Wildlife Board.


The first Indian national park was established in 1936 as Hailey National Park, and later renamed Corbett National Park.


In 1972, the Government of India enacted the Wildlife Conservation Act with the intention of effectively protecting the country 's wildlife and regulating wildlife trafficking, smuggling and illegal trade.


Another initiative called 'Project Tiger' was initiated in 1973 to save Royal Bengal Tigers' declining population. India boasts a total of 104 national parks.


'Project Elephant' was introduced later in 1992, with the goal of preserving the vulnerable wild Asian elephants and their habitat.


Kanha National Park and Bandhavgarh National Park are among the best national parks in India to spot Royal Bengal Tigers situated in the state of Madhya Pradesh.


Parambikulam Tiger Reserve in Kerala in the southern part of India is very famous for its spectacular sightings of wildlife. The Maharashtra and Gujarat states boast incredibly rich wildlife in the west region.


Tadoba Andhari Tiger Reserve is a popular wildlife destination of Maharashtra located some 145 km from Nagpur. Gir National Park is renowned for its magnificent Asian lions while in Gujarat.


What is a Wildlife Sanctuary?

Wildlife Sanctuary is a demarcated area for the conservation of a particular flora and fauna species.


The State authorities can require restricted human activities for the people living within it. For example, Wildlife authorities can require the grazing of livestock for a particular group living there.


Any neglect of wildlife is criminal crime and destruction of forest resources requires a National or State Wildlife Board approval.


First wildlife sanctuary in India is Vedanthangal Lake Birds Wildlife Sanctuary. It was created in 1936. 

  • Arial Island WLS

  • Bamboo Island WLS

  • Wild Ass WLS

  • Kibber WLS

  • Narsinghgarh WLS

  • Tipeshwar WLS

These are some of the list of wildlife sanctuaries in India


In this article, let’s see the difference between wildlife sanctuary and national park.


Difference Between Wildlife Sanctuary and National Park

Wildlife Sanctuary

National Park

It is a natural protected habitat which provides safety and favourable living conditions to wildlife containing the rare or endangered species of plants, animals, insects etc.

It is an area of land  preserved by the national government to conserve its entire ecosystem like its natural beauty along with the wildlife.

It mainly provides safety to birds, animals, insects, reptiles and other organisms.

It shields the entire ecosystem of the land plants, animals, historic objects and landscapes, etc.

Here, limited human activities are allowed, since it is not a highly restricted area, nce

It is a highly controlled area; human activities are not allowed.

It has no boundaries which are visible or marked. .

It has visibly marked boundaries.

It can be owned by either the government or a private organization.

It is preserved by the government only.

It is under IUCN category IV protected area.

It is under IUCN category II protected area.

  • It preserves approximately 45 Bengal tigers

Periyar National Park:

  • It has core zone is 135 square miles and creates watershed of two major rivers

  • Periyar is well known for its thick, tropical evergreen forests.  

Gir National Park:

  • It is the only remaining natural habitat of the Asiatic lion. In fact, it is the only place in the world where you can see lions roaming wild outside of Africa.

  • Gir National Park is the Asiatic lion's only remaining natural habitat. In reality, Gir is the only place in the world where lions can be seen wildly roaming outside Africa.

  • However, through the involvement of the Junagadh Nawabs and the Forest Department, Currently 523 lions are there in Gir National Park.

Sundarbans National Park:

  • It has 513 square miles, Sundarbans National Park is situated within a larger UNESCO Biosphere Reserve and the Sunderbans Tiger Reserve.

  • Approximately 100 Bengal tigers live in the watery world of the Sundarbans, having adapted to an almost amphibious life.

Nanda Devi Biosphere and Valley of Flowers National Parks:

  • It is the India’s second highest peak, is acclaimed as a goddess by Hindus, governs the national park, and has helped preserve and protect the region

  • Both parks contain noteworthy populations of endangered species, including the snow leopard and Himalayan musk deer.

Jim Corbett National Park:

  • Corbett is home to more than 200 Bengal tigers and is considered as the highest number of any tiger reserve in India. Corbett is also a famous place for birding, with roughly 650 species of resident and migratory bird

Key Points:

National Parks and Wildlife Sanctuaries in India are created along with Biosphere Reserves solely to protect some of the rare and endangered species of both flora and fauna. The sanctuary of wildlife and national parks are protected areas and all host a large range of wild animals and birds. A sanctuary may be converted to a national park, but not the vice versa.

FAQs on National Parks and Wildlife Sanctuaries in Biodiversity Conservation

1. What is a National Park in biology and environmental science?

A National Park is a legally protected area established to conserve entire ecosystems, including wildlife, plants, and natural landscapes. It is created to protect biodiversity and natural habitats from human interference.

  • No human activities like hunting, grazing, or private ownership are allowed.
  • It protects whole ecosystems, not just specific species.
  • Examples include Jim Corbett National Park and Kaziranga National Park.

2. What is a Wildlife Sanctuary?

A Wildlife Sanctuary is a protected area where animals and their habitats are conserved, but limited human activities may be permitted. It mainly focuses on protecting specific wild animal species.

  • Grazing or regulated human activities may be allowed.
  • It provides safe breeding and living conditions for wildlife.
  • Example: Periyar Wildlife Sanctuary.

3. What is the difference between a National Park and a Wildlife Sanctuary?

The main difference between a National Park and a Wildlife Sanctuary is the level of protection and human interference allowed.

  • National Park: No human activities, strict protection of entire ecosystems.
  • Wildlife Sanctuary: Limited human activities allowed, mainly protects specific species.
  • National Parks have stricter legal regulations than Sanctuaries.

4. Why are National Parks and Sanctuaries important for biodiversity conservation?

National Parks and Wildlife Sanctuaries are important because they protect biodiversity and prevent species extinction. They help maintain ecological balance by conserving:

  • Endangered species
  • Natural habitats like forests, wetlands, and grasslands
  • Food chains and ecological interactions
They reduce habitat destruction and support long-term ecosystem stability.

5. How do National Parks help in ecosystem protection?

National Parks help in ecosystem protection by conserving complete ecosystems in their natural state. They protect:

  • Flora and fauna together
  • Natural resources like soil and water
  • Ecological processes such as pollination and nutrient cycling
This ensures the survival of multiple interconnected species.

6. Can humans live inside a National Park?

Humans are generally not allowed to live permanently inside a National Park. These areas are strictly protected to minimize human disturbance.

  • No private ownership of land is allowed.
  • Activities like hunting, farming, and grazing are prohibited.
  • Only regulated tourism and research are permitted.

7. What types of animals are protected in Wildlife Sanctuaries?

Wildlife Sanctuaries protect a wide range of animals, especially endangered and threatened species. These may include:

  • Birds such as migratory and native species
  • Reptiles and amphibians
The aim is to provide safe habitats for breeding and survival.

8. What is the role of National Parks in protecting endangered species?

National Parks play a major role in protecting endangered species by offering them secure and undisturbed habitats. They help by:

  • Preventing poaching and illegal hunting
  • Preserving natural breeding grounds
  • Maintaining genetic diversity within populations
This reduces the risk of extinction.

9. What is biodiversity and how is it conserved in protected areas?

Biodiversity is the variety of living organisms, including plants, animals, and microorganisms, in a particular area. In National Parks and Sanctuaries, biodiversity is conserved by:

  • Protecting natural habitats
  • Restricting human exploitation
  • Monitoring and managing wildlife populations
This supports ecological balance and sustainable ecosystems.

10. What are biosphere reserves and how are they different from National Parks?

A Biosphere Reserve is a large protected area that includes core zones, buffer zones, and transition areas for conservation and sustainable use. Unlike National Parks:

  • Human settlements may exist in buffer and transition zones.
  • They promote sustainable development along with conservation.
  • They often include one or more National Parks or Sanctuaries within them.
