Botany - Biodiversity and its Conservation Question with Solution | TestHub

Biodiversity hotspots: These are the regions that are characterized with:

(i) Very high levels of species richness.

(ii) High degree of endemism (species found in only a specific region and nowhere else).

- Number of Biodiversity hotspots' worldwide : Initially 25, now 34.

- These hotspots are also the regions of accelerated habitat loss. If strict protection of these hotspots is done, it may reduce the ongoing mass extinctions by almost 30%.

- In India, 3 hotspots are present: 1. Western Ghats. 2. Indo-Burma. 3. Himalaya.

- All the biodiversity hotspots cover less than 2 % of the earth's land area but the species diversity is very high.
