A biodiversity hotspot is an area with unusual concentration of species, many of which are endemic. It is marked by serious threat to its biodiversity. To qualify as a hotspot, a region must meet two strict criteria:
Endemism: it must contain at least 1,500 species of vascular plants (> 0.5 percent of vascular plants (> 0.5 percent of the world’s total) as endemics, and;
Loss of Habitat: it has to have lost at least 70 percent of its original habitat.
Accordingly, 34 biodiversity hotspots have been so far identified. Collectively, the Biodiversity hotspots support 60% of world’s plant and animal species with a high share of endemics and cover around 2.5% of Earth’s land surface.
India shares its territories into three biodiversity hotspots viz. Eastern Himalaya, Western Ghats and Indo-Burma. Out of them, Eastern Himalaya and Western Ghats and Indo-Burma. Out of them, Eastern Himalaya and Western Ghats are mostly located within India’s territory. In the Indo-Burma Biodiversity, India shares only a small part in north East India.
So the correct option is 'both assertion and reason are incorrect'.
