Wildlife population

India is one of the most biodiverse regions and is home to a large variety of wildlife. It is one of the 17 megadiverse countries and includes three of the world's 36 biodiversity hotspots – the Western Ghats, the Eastern Himalayas, and the Indo-Burma hotspot.[1][2]

About 24.6% of the total land area is covered by forests. It has various ecosystems ranging from the high altitude Himalayas, tropical evergreen forests along the Western Ghats, desert in the north-west, coastal plains and mangroves along the peninsular region. India lies within the Indomalayan realm and is home to about 7.6% of mammal, 14.7% of amphibian, 6% of bird, 6.2% of reptilian, and 6.2% of flowering plant species.

Human encroachment, deforestation and poaching are significant challenges that threaten the existence of certain fauna and flora. Government of India established a system of national parks and protected areas in 1935, which have been subsequently expanded to nearly 1022 protected areas by 2023. India has enacted the Wildlife Protection Act of 1972 and special projects such as Project Tiger, Project Elephant and Project Dolphin for protection of critical species.

Fauna[edit]

India has an estimated 92,873 species of fauna, roughly about 7.5% of the species available worldwide.[3][4] Insects form the major category with 63423 recorded species. India is home to 423 mammals, 1233 birds, 526 reptiles, 342 amphibians, 3022 fish apart from other species which form 7.6% of mammal, 14.7% of amphibian, 6% of bird, 6.2% of reptilian species worldwide.[3][5]

Many Indian species are descendants of species originating in Gondwana, of which India originally was a part. Peninsular India's subsequent movement towards, and collision with, the Laurasian landmass set off a mass exchange of species. However, volcanism in the Deccan Traps and climatic change 20 million years ago caused the extinction of many endemic Indian forms.[6] Soon thereafter, mammals entered India from Asia through two zoogeographical passes on either side of the emerging Himalayas.[7] As a result, among Indian species, only 12.6% of mammals and 4.5% of birds are endemic, contrasting with 45.8% of reptiles and 55.8% of amphibians[5]

India is home to several well-known large animals, including the Indian elephant,[8] Indian rhinoceros,[9] and Gaur.[4] India is the only country where the big cats tiger and lion exist in the wild. Members of the cat family include Bengal tiger,[10] Asiatic lion,[11] Indian leopard,[12] snow leopard,[13] and clouded leopard.[14] Representative and endemic species include blackbuck, nilgai, [bharal]], barasingha, Nilgiri tahr and Nilgiri langur.[4]

There are about 31 species of aquatic mammals including dolphins, whales, porpoises and dugong.[15] Reptiles include the gharial, the only living members of Gavialis and saltwater crocodiles.[4] Birds include peafowl, pheasants, geese, ducks, mynas, parakeets, pigeons, cranes, hornbills and sunbirds.[4] Endemic bird species include great Indian hornbill, great Indian bustard, nicobar pigeon, ruddy shelduck, Himalayan monal and Himalayan quail.[16][17]

Flora[edit]

About 24.6% of the total land area is covered by forests.[18] It has various ecoregions ranging from the high altitude Himalayas, tropical evergreen forests along the Western Ghats, desert in the north-west, coastal plains and mangroves along the peninsular region.[19]

There are about 29,015 species of plants including 17,926 species of flowering plants. This is about 9.1% of the total plant species identified worldwide and 6,842 species are endemic to India. Other plant species include 7,244 algae, 2,504 bryophytes, 1,267 pteridophytes and 74 gymnosperms.[3] One-third of the fungal diversity of the world exists in India with over 27,000 recorded species, making it the largest biotic community after insects.[20][21]

Conservation[edit]

Main article: Conservation in India

India harbors 172 (2.9%) IUCN-designated threatened species.[22] These include 39 species of mammals, 72 species of birds, 17 species of reptiles, three species of amphibians, two species of fish, and a number of insects including butterflies, moths, and beetles.[4][23]

Human encroachment, deforestation and poaching are significant challenges that threaten the existence of certain fauna and flora. Government of India established a system of national parks and protected areas in 1935, which have been subsequently expanded to nearly 1022 protected areas by 2023. Various laws have been enacted such as Indian Forest Act, 1927 and Wildlife Protection Act of 1972 and special projects such as Project Tiger, Project Elephant and Project Dolphin have been initiated for the protection of forests, wildlife and critical species.[7][24]

As of 2023, there are 1022 protected areas including 106 national parks, 573 wildlife sanctuaries, 220 conservation reserves and 123 community reserves. In addition, there are 55 tiger reserves, 18 biosphere reserves and 32 elephant reserves.[18]
