A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation.

To qualify as a biodiversity hotspot a region must meet two strict criteria: it must contain at least 0.5% or 1,500 species of vascular plants as endemics, and it has to have lost at least 70% of its primary vegetation.

Around the world, 36 areas qualify under this definition. These sites support nearly 60% of the world’s plant, bird, mammal, reptile, and amphibian species, with a very high share of those species as endemics. Some of these hotspots support up to 15,000 endemic plant species and some have lost up to 95% of their natural habitat.
