How many biological hotspots are located in India?

India is part of four of the world's biodiversity hotspots recognised for exceptional yet threatened richness.

A single hotspot understates the country's coverage across several distinct biogeographic zones.

Two hotspots reflects an older count before further regions were added to the global list.

Three still omits one of the zones that touch Indian territory.

The four are the Himalaya, the Western Ghats and Sri Lanka, Indo-Burma, and Sundaland covering the Nicobar Islands.

A biodiversity hotspot must have high endemism and have lost most of its original habitat.
