Endemic Species, Features, Endemic Species of India and World

Endemic Species are organisms that exist naturally in only one specific geographic region and nowhere else on Earth. Their restricted distribution usually develops due to long geographical isolation, specialised environmental adaptations and evolutionary processes. Such species often evolve unique traits suited to narrow habitats, which also makes them highly vulnerable to habitat loss, pollution, climate change and human disturbance.

Endemic Species Features

Endemic Species have limited geographic distribution and evolve specialised adaptations to survive in particular environmental conditions, increasing vulnerability significantly.

• Geographic Distribution: Endemic organisms occur naturally in only one defined region such as a mountain range, island, or forest ecosystem and cannot naturally survive outside that location.
• Specialised Environmental Adaptation: Many endemic organisms develop unique physical or behavioural traits that allow survival only within specific ecological conditions or micro habitats.
• High Extinction Vulnerability: Because their population exists only in one location, any habitat destruction, pollution, or ecological disturbance can rapidly push them towards extinction.
• Evolution: Some species became endemic when populations that were once widespread gradually disappeared from most regions due to climate shifts or environmental pressures.
• Pollution Effects: Contamination of water, soil and air significantly affects Endemic Species because they cannot easily migrate to safer habitats.
• Adaptation to Local Climate: Endemic Species are usually finely tuned to local temperature, rainfall patterns and food availability, making them sensitive to climatic shifts.
• Conservation Significance: Protecting Endemic Species is important because their extinction would permanently remove a unique genetic lineage from the planet.

List of Endemic Species in India

India hosts numerous Endemic Species concentrated mainly in biodiversity hotspots such as the Western Ghats, Himalayas, North-East India and island ecosystems. The list of Endemic Species found in India are:

• Asiatic Lion (Gir Forest): The Asiatic lion survives naturally only in Gir National Park of Gujarat. It is smaller than African lions and listed as endangered.
• Kashmir Stag (Hangul): The Hangul lives mainly in Dachigam National Park in Kashmir Valley and nearby regions. It represents the only surviving red deer lineage in India.
• Lion Tailed Macaque: This rare primate inhabits evergreen forests of the Western Ghats and is recognised for its distinctive silver mane surrounding the face.
• Purple Frog: Also called the Pignose frog, this amphibian remains underground for most of the year in Western Ghats rainforests and emerges briefly during breeding season.
• Sangai Deer: Known as the Brow Antlered Deer, this species survives only in Keibul Lamjao National Park of Manipur located in the floating wetlands of Loktak Lake.
• Nilgiri Tahr: A mountain goat species adapted to steep rocky slopes of the Nilgiri Hills in the Western Ghats and classified as endangered.
• Pygmy Hog: Found mainly in Assam’s Manas region, it is the world’s smallest wild pig species and depends on tall grassland ecosystems.
• Malabar Grey Hornbill: A fruit eating bird endemic to Western Ghats forests, recognised by its curved beak and casque structure.
• Rufous Babbler: This small forest bird with reddish plumage occurs mainly in dense vegetation of the Western Ghats.
• Black and Orange Flycatcher: A colourful bird inhabiting montane forests of the Western Ghats and known for its distinctive black and orange feathers.
• Nilgiri Wood Pigeon: This large forest pigeon lives in dense evergreen forests of the Nilgiri Hills region.

• White Cheeked Barbet: A green bird with characteristic white cheek patches found mainly in forest regions of the Western Ghats.
• Nilgiri Pipit: A grassland bird adapted to high altitude mountain ecosystems in the Nilgiri region.
• White Bellied Treepie: A long tailed tree dwelling bird found exclusively in forest ecosystems of the Western Ghats.
• Malabar Gliding Frog: A large tree frog capable of gliding between trees using webbed feet in humid Western Ghats forests.
• Great Nicobar Serpent Eagle: A bird of prey endemic to Great Nicobar Island feeding mainly on reptiles.
• Andaman Woodpecker: A black woodpecker species inhabiting dense forest ecosystems of the Andaman Islands.
• Narcondam Hornbill: A rare hornbill species restricted to Narcondam Island in the Andaman Sea.
• Green Avadavat: A bright green finch species found mainly in central India.
• Yellow Throated Bulbul: A bird species with a distinctive yellow throat inhabiting rocky hills and dry forests of peninsular India.
• Kokum Plant: A medicinal plant species native to evergreen forests of the Western Ghats region.
• Kurinji Plant: A flowering shrub famous for blooming once every twelve years across hills of the Western Ghats.
• Indian Pitcher Plant: A carnivorous plant species confined mainly to Khasi Hills of Meghalaya.
• Andhra Pradesh Cycas: A gymnosperm plant endemic to dry forest ecosystems of Andhra Pradesh.
