Three of the following criteria have contributed to the recognition of...
Biodiversity hotspot:
(i) 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. A hotspot, in other words, is irreplaceable. Hence, statements 1 and 3 are correct.
- It must have 30% or less of its original natural vegetation. In other words, it must be threatened. Hence statement 5 is correct.
(ii) Around the world, 36 areas qualify as hotspots. They represent just 2.4% 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.
(iii) Conservation International was a pioneer in defining and promoting the concept of hotspots.
(iv) In 1989, just one year after scientist Norman Myers wrote the paper that introduced the hotspots concept, Conservation International adopted the idea of protecting these incredible places as the guiding principle of our investments.

Three of the following criteria have contributed to the recognition of...
Recognition of Western Ghats-Sri Lanka and Indo-Burma regions as hotspots of biodiversity
The Western Ghats-Sri Lanka and Indo-Burma regions have been recognized as hotspots of biodiversity due to several criteria. Among the given options, the correct criteria in this context are:
1) Species richness
2) Vegetation density
3) Endemism
4) Ethno-botanical importance
5) Threat perception
6) Adaptation of flora and fauna to warm and humid conditions
Species richness:
The Western Ghats-Sri Lanka and Indo-Burma regions are known for their extraordinary species richness. These areas are home to a wide variety of plant and animal species, including many endemic and threatened species. The high diversity of species present in these regions is one of the key factors contributing to their recognition as biodiversity hotspots.
Endemism:
Endemism refers to the occurrence of species exclusively in a particular geographic region. Both the Western Ghats-Sri Lanka and Indo-Burma regions are characterized by a high degree of endemism. Many plant and animal species found in these regions are unique and found nowhere else in the world. This unique biodiversity is a significant factor in their recognition as hotspots.
Adaptation of flora and fauna to warm and humid conditions:
The Western Ghats-Sri Lanka and Indo-Burma regions have warm and humid climates, which have led to the evolution of diverse flora and fauna adapted to these conditions. The plant and animal species in these regions have developed specialized adaptations to survive and thrive in the warm and humid environments. This adaptation to specific climatic conditions further adds to the biodiversity and ecological significance of these areas.
Vegetation density, Ethno-botanical importance, and Threat perception:
While vegetation density, ethno-botanical importance, and threat perception are important factors in understanding the biodiversity and conservation status of an area, they are not specifically mentioned as criteria for the recognition of the Western Ghats-Sri Lanka and Indo-Burma regions as hotspots of biodiversity.
In conclusion, the criteria that have contributed to the recognition of the Western Ghats-Sri Lanka and Indo-Burma regions as hotspots of biodiversity are species richness, endemism, and the adaptation of flora and fauna to warm and humid conditions. These factors highlight the uniqueness and ecological importance of these regions and emphasize the need for their conservation.
