Protected Areas, Conventions and Organisations

Think of India's wild places as a ladder of protection. At the top are areas where almost nothing is allowed except nature itself, and lower down are areas where people and wildlife share the land under rules. This ladder is created by the Wild Life (Protection) Act, 1972, and every park, sanctuary or reserve you will meet in this chapter sits on one of its rungs.

The Act recognises four kinds of protected area: National Parks, Wildlife Sanctuaries, Conservation Reserves and Community Reserves. The last two were added by the 2002 amendment so that even government land linking two parks, or village land that people wish to protect themselves, could be brought under the law. A National Park is the strictest of the four: grazing, private rights and the collection of forest produce are not allowed, and its boundaries are fixed by notification. In a Sanctuary, killing animals is banned, but with the permission of the Chief Wildlife Warden some human activities such as limited grazing may continue.

Notice that Tiger Reserves, Biosphere Reserves and Elephant Reserves are not extra rungs on the legal ladder. They are management layers placed over the same land: a Tiger Reserve usually contains a National Park or Sanctuary, and a Biosphere Reserve may contain several of them. This is why Simlipal can be a National Park, a Tiger Reserve and a Biosphere Reserve at the same time. Around many parks the government also notifies an Eco-Sensitive Zone (ESZ), a buffer where industry and mining are regulated; the usual guideline distance is up to 10 km.

The Act also keeps a list of protected species in Schedules. After the 2022 amendment the Schedules were reduced from six to four: Schedule I (highest protection, for example Tiger, Lion, Elephant, Great Indian Bustard), Schedule II (lesser protection), Schedule III (protected plants, earlier Schedule VI) and Schedule IV (species listed under CITES). Separately, the IUCN Red List is a world-wide status list: a species can be Critically Endangered on the Red List and sit in Schedule I of the Indian Act at the same time, as the Great Indian Bustard does. Do not mix the two lists.

A National Park is easiest to remember as a pair: a name and a reason. Kaziranga means the one-horned rhino, Gir means the Asiatic lion, Keibul Lamjao means a park that floats. Examiners almost never ask for a park in isolation; they ask for its state, its star animal, or the one feature that makes it unique. So in this topic learn every park with its state first, and the star feature second.

The tiger is India's national animal, and the story of its protection is the story of Project Tiger, launched on 1 April 1973 from Jim Corbett National Park. It began with nine reserves (Corbett, Manas, Palamau, Simlipal, Ranthambore, Sundarbans, Kanha, Bandipur and Melghat) and has grown into a network of more than fifty tiger reserves. Since 2006 it is run by the statutory National Tiger Conservation Authority (NTCA). Each reserve is planned in two zones: a core (critical tiger habitat) kept free of human use, and a buffer where people and wildlife share the land.

The numbers show the result. India's tiger estimate for 2022 was about 3,167 tigers, and the country holds a large majority of the world's wild tigers. Among the states, Madhya Pradesh had the most, followed by Karnataka, Uttarakhand and Maharashtra. The census is repeated every four years. Remember that tigers live in many kinds of forest, from the mangroves of the Sundarbans to the grasslands of the Terai, so tiger reserves are spread across the country.

Wildlife Sanctuaries are far more numerous than National Parks, and examiners like to ask them in a match-the-following. Learn the sanctuary together with its river, lake or special animal, because that is usually the clue. For example, Gandhi Sagar sits on the Chambal and was chosen as the second home of the cheetah, while the National Chambal Sanctuary protects the gharial in a three-state stretch of the river.

A National Park protects a patch of forest. A Biosphere Reserve protects a whole landscape, together with the people who live in it. The idea comes from UNESCO's Man and the Biosphere (MAB) Programme, started in 1971, which asks countries to nominate large areas where conservation and local livelihoods can go hand in hand. In India the Ministry of Environment, Forest and Climate Change (MoEFCC) first declares an area a Biosphere Reserve, and only some of them are later accepted by UNESCO into the World Network of Biosphere Reserves.

India has 18 Biosphere Reserves. Of these, 13 are in the UNESCO World Network of Biosphere Reserves as of 2025, and the rest are national only. The first Biosphere Reserve of India is the Nilgiri (1986), spread over Tamil Nadu, Kerala and Karnataka. The largest is the Great Rann of Kachchh in Gujarat. Study the table below with three columns in mind: state, year declared, and whether UNESCO has recognised it.

A wetland is land that is wet for much or all of the year: lakes, marshes, mangroves, lagoons, river floodplains and even shallow coastal waters. They act like the earth's kidneys, filtering water, storing floods and feeding millions of birds and fish. The treaty that protects them is the Ramsar Convention, signed on 2 February 1971 at Ramsar in Iran, which is why World Wetlands Day falls on 2 February. India joined the Convention in 1982.

The most important number to remember is a moving one, so always read the date in the question. As of August 2026 India has 101 Ramsar sites, the largest number in South Asia, and Tamil Nadu has more of them than any other state. The count has grown quickly because every year the government nominates new wetlands. Treat any figure as 'as of' a date, and expect it to be higher in later exams.

In India wetlands are also protected at home. The Wetlands (Conservation and Management) Rules, 2017 replaced the earlier 2010 rules and hand most of the day-to-day management to the states through State Wetland Authorities. The National Plan for Conservation of Aquatic Ecosystems (NPCA) funds restoration of lakes and wetlands. These are domestic rules; a Ramsar tag alone does not create a legal park or sanctuary.

Indian environmental law grew in stages, and each big law is a response to a problem. The 1970s brought laws for wildlife and water because forests and rivers were visibly dying. The 1980s brought laws for forests and air, and then the Bhopal gas tragedy of December 1984 forced the country to write an umbrella law, the Environment (Protection) Act, 1986. Learn the laws as a story with years, and the years will stay with you.

The Constitution gives these laws a base. Article 48A (a Directive Principle) tells the State to protect and improve the environment, forests and wildlife; Article 51A(g) makes it a Fundamental Duty of every citizen to protect the natural environment; and the Supreme Court reads a healthy environment into the right to life under Article 21. Environmental treaties are turned into Indian law through Article 253, which lets Parliament legislate to implement international agreements.

Nature does not stop at a country's border: a migratory bird, a river, or the ozone layer belongs to everyone. So nations sign treaties, and each treaty has a year, a place, a purpose and a secretariat city. The exam asks exactly those four things, so build the habit of reading every convention as: what, when, where, why. Two big meetings are the roots of this whole topic, the Stockholm Conference of 1972 and the Rio Earth Summit of 1992.
