The primary function of biodiversity hotspots in conservation efforts is to prioritize areas with significant species richness that are also under threat from human activities. These regions are critical for biodiversity conservation because they support numerous endemic species and provide essential ecosystem services. By focusing conservation resources on hotspots, efforts can maximize impact and protect vital habitats. Identifying and safeguarding these areas is crucial for mitigating biodiversity loss and fostering more resilient ecosystems in a rapidly changing world.
