Biodiversity hotspots are geographic areas that contain high levels of species diversity but are threatened with extinction. To qualify as a hotspot, a region must meet two strict criteria: It must contain at least 1,500 species of vascular plants (> 0.5 percent of the worlds total) as endemics. It has to have lost at least 70 percent of its original habitat. Three factors that usually determine hotspots:
The number of total species (species richness).
The number of unique species (endemism).
The number of species at risk (threat of extinction).
