To qualify as a biodiversity hotspot, an area must meet two strict criteria:

- It must contain at least 1,500 species of vascular plants found nowhere else on Earth (endemism).

- It must have lost at least 70 percent of its primary native vegetation.

India is a part of 3 such biodiversity hotspots:
- Himalayas
- Indo-Burma region
- Western Ghats and Sri Lanka
