To qualify as a biodiversity hotspot, a region must meet two strict criteria: It must have at least 1,500 vascular plants as endemics — which is to say, it must have a high percentage of plant life found nowhere else on the planet. A hotspot, in other words, is irreplaceable.

- The number of total species (species richness).
- The number of unique species (endemism).
- The number of species at risk (threat of extinction).
