What is Biodiversity Hotspot?
Historical Background
Key Points
9 points- 1.
High endemism: Presence of a large number of species found nowhere else.
- 2.
Significant habitat loss: At least 70% of the original habitat has been lost.
- 3.
Focus on vascular plants as indicators of biodiversity.
- 4.
Globally, 36 areas qualify as hotspots, representing just 2.5% of Earth's land surface.
- 5.
These hotspots support more than half of the world’s plant species as endemics and nearly 43% of bird, mammal, reptile and amphibian species as endemics.
- 6.
Examples include the Western Ghats and Sri Lanka, Indo-Burma, and Sundaland in India and Southeast Asia.
- 7.
Conservation efforts in hotspots are crucial for preventing mass extinctions.
- 8.
Threats include deforestation, habitat fragmentation, invasive species, and climate change.
- 9.
Conservation International plays a key role in identifying and protecting biodiversity hotspots.
Visual Insights
India's Four Biodiversity Hotspots
This map illustrates the geographical locations of the four major biodiversity hotspots in India, crucial for understanding their distribution and conservation importance. The Western Ghats, highlighted in the news, is one of these critical regions.
- 📍Western Ghats — High Endemism, Threatened by Tourism
- 📍Himalaya — Rich Alpine & Sub-alpine Biodiversity
- 📍Indo-Burma — Diverse Flora & Fauna, Riverine Ecosystems
- 📍Sundaland — Island Ecosystems (Nicobar Islands)
