The two criteria for designation as a biodiversity hotspot are:

1. It must possess at least 1500 vascular plant species as endemics : It means the region must have a high percentage of plant species which are found no where else in the world.

2. It must have 30% or less native vegetation : It means that the plant species population is endangered and threatened to extinction.
