Study Notes

Hot Spots of Biodiversity

Biodiversity hotspots are biogeographic regions with significant biodiversity under threat.
India has four major biodiversity hotspots:
- The Western Ghats
- The Eastern Himalayas
- Indo-Burma
- Sundaland (Nicobar Islands)

Endangered Species

Endangered species face imminent extinction threats.
Notable endangered animals in India include:
- Red panda
- Gir lion
- Gharial
- Great Indian bustard

Vulnerable Species

Vulnerable species are likely to become endangered without improved survival conditions.
Examples in India include:
- Sarus crane
- Nilgiri Langur
- Barasingha

Rare Species

Rare species are uncommon and often found in isolated locations.
The term "rare" designates species that are not endangered but considered at risk.

Red Data Book

Compiled by the International Union for Conservation of Nature (IUCN).
Documents rare and endangered species of plants, animals, fungi, and local species within specific regions.

Black Buck

Known as kala hiran in India.
Previously widespread across India, now limited to certain states like Punjab, Gujarat, and Haryana.
Open plains need conservation efforts for black buck survival.

Values of Biodiversity

Survival relies on biodiversity for food, fuel, and medicines.
Ethical and aesthetic values stem from appreciation of existence and beauty in nature, fostering eco-tourism.

Endemic Species

Species endemic to a region are confined there or have originated there.
Examples include:
- True Cardamom
- Peepal tree
- One-horned rhino

EDGE Species

Evolutionarily Distinct and Globally Endangered (EDGE) species have unique evolutionary history.
Examples include:
- Asian elephants
- Chinese pangolin
- Malayan tapir

Conservation of Biodiversity

Wildlife conservation focuses on protecting species and their habitats through two approaches:
- In situ Conservation: Protection within natural habitats.
- Ex situ Conservation: Protection away from natural habitats.

In-situ Conservation

National Parks: Areas dedicated to conserving wildlife and natural scenery; no human inhabitation allowed.
Wildlife Sanctuaries: Protected areas where interference with natural life is prohibited; hunting and capturing are restricted.

Phyto-geographical Regions of India

India is classified into several phytogeographical regions based on flora:
- Western Himalayas
- Eastern Himalayas
- Western Deserts
- Gangetic Plains
- Central India
- Western Coast
- Deccan Plateau
- North-East India
- Andaman and Nicobar Islands

Zoo-geographical Regions of India

India's faunal diversity is categorized into:
- Himalayan Region
- Malabar Region
- Nilgiri Region
- Northern Plains
- Desert Lands
- Deccan Plateau Region

India: A Mega-diversity Nation

India is recognized as one of the 18 mega-diverse countries identified by Conservation International in 1998.
Areas of diversity include geographical, climatic, biodiversity, habitat, and cultural diversity.
