Q. Which of the following criteria must be fulfilled for a region to be designated as a ‘biodiversity hotspot’ on the world hotspots map?- The region must contain at least 0.5 percent or 1,500 species of vascular plants as endemic species.
- The region must have lost at least 70 percent of its primary vegetation.
Select the correct option from the codes given below:
Answer:
Both 1 and 2
Notes: A ‘biodiversity hotspot’ must meet both criteria: (1) at least 0.5% or 1,500 endemic species of vascular plants; (2) loss of at least 70% of its original or primary vegetation. This definition was given by Norman Myers in 2000 and is widely accepted for global hotspot identification, thus both statements are correct.
