Biodiversity Overview

Biodiversity refers to the variation of plant and animal species within a specific habitat.
Major components include species richness (number of different species) and species evenness (distribution of species).
India boasts rich biodiversity, with forests and trees covering 23.39% of its geographical area.

Biodiversity Hotspots Definition

Coined by Norman Myers, "Biodiversity hotspots" are regions characterized by high species richness and endemism.
Regions must meet two criteria to qualify as a hotspot:
- Must contain at least 1,500 species of vascular plants.
- Must retain 70% of its original habitat.
