Biodiversity hot spots
Biodiversity hotspots are biogeographic regions that are both exceptionally rich in endemic species and under severe threat from human activities, primarily habitat destruction. To qualify as a hotspot, an area must meet two strict criteria: it must contain at least 1,500 species of vascular plants as endemics (meaning they are found nowhere else on Earth), and it must have lost at least 70% of its primary vegetation.
These hotspots, despite covering only about 2.5% of the Earth's land surface, harbor an incredibly disproportionate amount of the world's plant and vertebrate diversity. Examples include the Western Ghats of India, the Mediterranean Basin, and Madagascar. Identifying and focusing conservation efforts on these hotspots is a strategic approach to protect a vast number of unique species and ecosystems, providing a high return on investment for global biodiversity preservation. Their designation highlights urgent areas where conservation interventions are critically needed to prevent mass extinctions.
