India has four biodiversity hotspots, out of the 36 biodiversity hotspots of the world. These regions are home to a wide variety of plants and animals, many of which cannot be found anywhere else on the planet.
From Bengal tigers in dense forests to rare birds in the Himalayas and unique island species in the Andamans, each hotspot offers a completely different kind of wildlife.
But while these regions are great for spotting wildlife, they are also under serious threat from habitat loss, making it critical to understand and protect them.
This guide breaks down where these hotspots are, what makes them so rich in life, and why they matter for your next wildlife vacation.

What are Biodiversity Hotspots?
A biodiversity hotspot is a region packed with plant and animal species that don’t exist anywhere else on Earth and is losing its natural habitat fast. The term was coined by biologist Norman Myers in 1988. Conservation International later built on his work to identify the specific regions that need urgent protection.
Simply put, a hotspot is a place where something is highly concentrated. In this case, that something is endemic species, plants and animals found only in that one region and nowhere else. When these species lose their habitat, they can’t just relocate to a different place. They risk going extinct altogether.
To officially qualify, a region must meet two biodiversity criteria set by Conservation International:
- Endemism: The area must have at least 1,500 native plant species found nowhere else on Earth.
- Habitat loss: The region must have already lost 70% or more of its original vegetation.

| Sundaland | Nicobar Islands (Andaman and Nicobar chain) | Nicobar Megapode, Saltwater Crocodile, Leatherback Turtle, Green Sea Turtle | Campbell Bay National Park, Galathea National Park |
1. Himalayas Biodiversity Hotspot
The Himalayas hotspot covers Jammu & Kashmir, Ladakh, Himachal Pradesh, Uttarakhand, Sikkim, Arunachal Pradesh, and northern West Bengal. It is one of the largest biodiversity hotspots in India. From forested foothills to towering peaks above 26,000 feet, the region is home to many different habitats.
In fact, this range is exactly why the region holds so much life. You’ll find alpine meadows, temperate forests, and glacier-fed valleys, each with their own set of species. Many of these are also endemic species of India. Of the 10,000+ plant species that grow here, roughly a third exist nowhere else.
You can find wildlife such as the snow leopard, red panda, Himalayan tahr, and blue sheep here, along with birds like the Western Tragopan and Himalayan monal. The Himalayas are also where the Ganga, Brahmaputra, and Indus rivers begin.
Parks like Great Himalayan National Park and Valley of Flowers National Park help protect this rich but fragile landscape.
2. Indo-Burma Biodiversity Hotspot
The Indo-Burma hotspot covers Northeast India and the Andaman Islands. It includes Assam, Meghalaya, Manipur, Mizoram, Nagaland, Tripura, and parts of Arunachal Pradesh. It is one of the most species-rich biodiversity hotspots in India, thanks to its mix of tropical forests, wetlands, and river systems.
This region is known for its huge variety of orchids and freshwater life. It is also home to thousands of plants, birds, reptiles, and amphibians that you can’t find anywhere else.
The Indo-Burma region supports a wide variety of wildlife, including Hoolock Gibbon, Clouded Leopard, Asian Elephant, Bengal Tiger, and Slow Loris, alongside hornbills and Gaur.
Most of the region is protected by parks like Kaziranga National Park, Manas National Park, and Namdapha National Park. The forests in this hotspot also support water conservation and carbon storage, and local communities depend on them for farming, fishing, and forestry.
3. Western Ghats & Sri Lanka Biodiversity Hotspot
The Western Ghats and Sri Lanka hotspot stretches along India’s western coast through Gujarat, Maharashtra, Goa, Karnataka, Kerala, and Tamil Nadu. Spanning about 1,000 miles parallel to the Arabian Sea, it supports an incredible range of habitats and wildlife. Its evergreen forests and high number of endemic species have earned it UNESCO World Heritage status.
The Western Ghats and Sri Lanka have very similar geology and climate, even though they are separated by about 250 miles of sea. Together, they form one of India’s richest biodiversity hotspots. The region is home to thousands of plant species and hundreds of birds, reptiles, and amphibians found nowhere else.
You can find wildlife such as the lion-tailed macaque, Nilgiri tahr, Malabar giant squirrel, great Indian hornbill, and purple frog here. The region is also an important habitat for Asian elephants and Bengal tigers.
Much of the terrain is protected by parks like Periyar National Park, Eravikulam National Park, and Bandipur National Park.
4. Sundaland Biodiversity Hotspot
The Sundaland hotspot is represented in India only by the Nicobar Islands, part of the Andaman and Nicobar chain. The region further extends to Indonesia, Malaysia, Brunei, Singapore, and southern Thailand. The Nicobars are the only region that falls within Indian territory.
Mangrove forests dominate the Nicobar Islands, and the United Nations declared them a world biosphere reserve back in 2013. The islands hold rich plant life, with hundreds of species found only here, along with a wide range of wild orchids.
Wildlife in this hotspot includes the Nicobar megapode, saltwater crocodile, and sea turtles like the leatherback and green sea turtle. The islands are also surrounded by beautiful coral reefs and seagrass beds.
Protected areas such as Campbell Bay National Park and Galathea National Park help preserve this fragile ecosystem.
Conservation Efforts for Biodiversity Hotspots in India
India’s biodiversity hotspots are protected through strong laws, protected areas, and support from local communities. National parks, wildlife sanctuaries, and biosphere reserves help safeguard important habitats from human activities and habitat loss.
There are two main laws for these efforts:
- Wildlife (Protection) Act, 1972: Conserves endangered species and regulates hunting and wildlife trade.
- Biological Diversity Act, 2002: Promotes the sustainable use of biological resources across the country.
These regulations have helped expand protected area networks in the Western Ghats, the Himalayas, Northeast India, and the Nicobar Islands. India also has species-specific programs, including:
- Project Tiger
- Project Elephant
- Project Snow Leopard
- Project Dolphin
These programs target the recovery of specific wildlife populations, backed by afforestation and habitat restoration work in degraded areas.
Local communities also play an important role in conserving these regions. Through Joint Forest Management, indigenous and local groups take part directly in protecting these lands. At the same time, eco-sensitive zones around parks help keep development pressures in check.
To Wrap Up
India’s four biodiversity hotspots, the Himalayas, Indo-Burma, Western Ghats & Sri Lanka, and Sundaland, hold some of the richest and most threatened wildlife on the planet.

FAQs
What are biodiversity hotspots?
Biodiversity hotspots are places with an unusually high number of plant and animal species found only in that region. In other words, these species don’t exist anywhere else on Earth. However, these areas are also highly threatened by habitat loss and human activities.
How many biodiversity hotspots are there in India?
India is home to four biodiversity hotspots: the Himalayas, Indo-Burma, Western Ghats & Sri Lanka, and Sundaland. Each of these regions supports a unique mix of endemic wildlife and plant species. Together, they make India one of the most ecologically diverse countries in the world.
Why are these hotspots important?
These hotspots are important because they protect plants and animals that cannot be found anywhere else on Earth. They also help regulate water, store carbon, and keep the climate stable. In addition, they support the livelihoods of millions of people through farming, forestry, and ecotourism.
What are the criteria for a region to be a biodiversity hotspot?
A region must have at least 1,500 native vascular plant species found nowhere else. It must have also lost 70% or more of its original vegetation due to human activity or environmental change. Both criteria have to be met for a region to earn hotspot status.
Which biodiversity hotspot covers the Western Ghats?
The Western Ghats are part of the Western Ghats and Sri Lanka biodiversity hotspot. This region stretches along India’s western coast and is a UNESCO World Heritage Site. Even though Sri Lanka is separated by the sea, the two regions share very similar geology and climate.
