what is biodiversity hotsopt? Why is india considered as a mega biodiversity hotspot?
A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation. An area is known as a hotspot if it contains at least 0.5% endemic plant species.
India is rich in biodiversity from north to southand from east to west. India contains many species that world’s gone country have.
India is called a mega diversity center because of the large number and the variety of organisms are found in this country. There are over 40,000 species of plants and over 90,000 species of animals living across a diverse geographical landscape, comprising of sea-coast, mountain, desert, forest, grassland, and marshland ecosystems, thus India is called as a mega biodiversity hotspot.
India hosts 4 biodiversity hotspots: the Himalayas, the Western Ghats, the Indo-Burma region and Sundaland (including the Nicobar Islands).

A biodiversity hotspot is a biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction.
To qualify as a biodiversity hotspot, an area must meet two strict criteria:
- Contain at least 1,500 species of vascular plants found nowhere else on Earth (known as "endemic" species).
- Have lost at least 70 percent of its primary native vegetation.
India is known for its rich heritage of Biological diversity, having already documented over 91,000 species of animals and 45,500 species of plants in its 10 biogeographic regions. Nearly 6,500 native plants are still used prominently in indigenous healthcare systems.
India a mega diversity country with only 2.4% of the land area of the world, but accounts for 7.8% of the recorded species of the world.
It hosts four biodiversity hotspots: the Himalayas, the Western Ghats, the Indo-Burma region and Sundaland (including the Nicobar Islands). These hotspots have numerous endemic species.
