A "Biodiversity Hotspot" is a region that is rich in unique plant and animal species but is also threatened by human activities. To qualify as a hotspot, an area must have at least 1,500 species of vascular plants that are endemic, meaning they are not found anywhere else in the world. Additionally, it must have lost at least 70% of its original habitat. These regions are crucial for conservation efforts because they support a high level of biodiversity, which contributes to ecosystem stability and resilience. Protecting biodiversity hotspots helps preserve not only the unique species but also the ecological processes that sustain life on Earth.
