What are 2 criteria for a biodiversity hotspot?
To qualify as a biodiversity hotspot, a region must meet two strict criteria:
- It must have at least 1,500 vascular plants as endemics — which is to say, it must have a high percentage of plant life found nowhere else on the planet. …
- It must have 30% or less of its original natural vegetation.
What are hotspots name the criteria for determining a hotspot?
Two criteria for determining biodiversity hotspots are:
- Regions with high levels of species richness, i.e., the number of different species represented in a region.
- Regions with high degree of endemism, i.e., species that are confined to one particular region only but not found anywhere else.
What are the characteristics of a biodiversity hot spot?
To qualify a hot spot area must contain at least 0.5% or 1,500 species of vascular plants as endemics, and should have lost at least 70% of its primary vegetation. The number of hot spots in the world has now increased to 36.

Hotspots are areas of high endemism and high species richness. All over the world, some 34 such spots have been identified, including 3 in India (Western Ghats, Indo- Burma and Himalayas). The environmental conditions in polar regions do not favour large number of species or species richness.

A hotspot is an area which faces serious threat from human activities and supports a unique biodiversity (endemic, threatened, rare species) with representatives of evolutionary of speciation and extinction. The concept of biodiversity was given by Norman Myers (1988).
