edit a biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation.[1][2] norman myers wrote about the concept in two articles in “the environmentalist” (1988),[3] and 1990[4] revised after thorough analysis by myers and others “hotspots: earth’s biologically richest and most endangered terrestrial ecoregions”[5] and a paper published in the journal nature.[6] to qualify as a biodiversity hotspot on myers 2000 edition of the hotspot-map, 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 75% of its primary vegetation.[6] around the world, 36 areas qualify under this definition.[7] 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.[7] biodiversity hotspots host their diverse ecosystems on just 2.4% of the planet's surface,[2] however, the area defined as hotspots covers a much larger proportion of the land. the original 25 hotspots covered 11.8% of the land surface area of the earth.[1] overall, the current hotspots cover more than 15.7% of the land surface area, but have lost around 85% of their habitat.[8] this loss of habitat explains why approximately 60% of the world's terrestrial life lives on only 2.4% of the land surface area.
