    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.
