A 'Biodiversity Hotspot' is defined as a region that must contain at least 1,500 species of vascular plants as endemics and has lost at least what percentage of its original habitat?
Show answer and explanation
Correct answer: 70%
To qualify as a biodiversity hotspot, a region must meet two strict criteria: it must contain at least 0.5% or 1,500 species of vascular plants as endemics, and it must have lost at least 70% of its primary vegetation. These areas are high priorities for global conservation efforts.
