*.it must contain at least 0.5% or 1,500 species ofvascular plants as endemics, and
*.it had lost at least 70% of its primary vegetation.
*.Around the world, 34 areas qualify under this definition, with nine other possible candidates.

Yet biodiversity hotspots are, by definition, in a conservation crisis. To be classified as a biodiversity hotspot, a region must have lost at least 70 percent of its original natural vegetation, usually due to human activity. There are over 30 recognized biodiversity hotspots in the world.
