Biodiversity hotspots host their diverse ecosystems on just 2.4% of the planet's surface. [2] Ten hotspots were originally identified by Myer; [1] the current 36 used to cover more than 15.7% of all the land but have lost around 85% of their area. [8]
What is a biodiversity hotspot? There are currently 36 recognized biodiversity hotspots. These are Earth’s most biologically rich—yet threatened—terrestrial regions. To qualify as a biodiversity hotspot, an area must meet two strict criteria:
What is a biodiversity hotspot? Around the world, 36 areas qualify as hotspots. Their intact habitats represent just 2.5% of Earth’s land surface, but they support more than half of the world’s plant species as endemics — i.e., species found no place else — and nearly 43% of bird, mammal, reptile and amphibian species as endemics.
5 Σεπ 2023 · Today, Conservation International defines a biodiversity hotspot as an area that contains at least 1,500 plants that are found nowhere else on Earth and that is under threat with less than a third of its natural vegetation remaining. The organization states that biodiversity underpins all life on Earth.
21 Ιουν 2024 · To be classified as a biodiversity hotspot, a region must have lost at least 70 percent of its original natural vegetation, usually due to human activity. There are over 30 recognized biodiversity hotspots in the world. The Andes Mountains Tropical Hotspot is the world’s most diverse hotspot.
Biodiversity hotspots are a method to identify those regions of the world where attention is needed to address biodiversity loss and to guide investments in conservation.
Biodiversity hotspots are regions that are exceptionally rich in species, ecologically unique and which may contain geographically restricted species. They are thus priority targets for nature conservation.
