FAQ About Biodiversity Hotspots

A biodiversity hotspot is a geographic area that is characterized by an exceptionally high level of species richness and a significant degree of habitat loss. These areas are recognized for their remarkable biological diversity and the high number of species that are found nowhere else in the world (endemic species). Biodiversity hotspots are defined not only by the sheer number of species they contain but also by the threats they face, primarily habitat destruction and other anthropogenic activities.

The concept of biodiversity hotspots was first introduced by British ecologist Norman Myers in 1988. He proposed a set of criteria to identify these hotspots, which include having at least 1,500 endemic plant species and having lost at least 70% of its original habitat. As of my last knowledge update in September 2021, there were 36 recognized biodiversity hotspots around the world.

These hotspots play a critical role in global biodiversity conservation because they are home to a disproportionate share of Earth's species. Despite covering only a small percentage of the Earth's land area, biodiversity hotspots contain a substantial proportion of the world's plant and animal species. Protecting and conserving these areas is crucial for preventing further loss of biodiversity and ensuring the long-term survival of many unique species.
