Standard

The section elaborates on India's rich biodiversity, covering the major types of vegetation, including Tropical Evergreen, Tropical Deciduous, Thorn Forests, Montane, and Mangrove forests. It emphasizes the significance of each type in maintaining the ecosystem and outlines the flora and fauna unique to these regions.

Detailed

Types of Vegetation in India

India, one of the 12 mega-biodiversity countries, is home to numerous plant and animal species. With approximately 47,000 plant species, natural vegetation can be classified into major types:

  1. Tropical Evergreen Forests: Found in regions with heavy rainfall, these forests remain green year-round and include species like ebony and mahogany. The diverse fauna includes elephants and one-horned rhinoceroses.
  2. Tropical Deciduous Forests: Also known as monsoon forests, they are predominant in India and can be divided into moist and dry deciduous forests, shedding leaves in the dry season. Key species include teak and sal, hosting animals like tigers and deer.
  3. Thorn Forests and Scrubs: Found in arid regions with less rainfall, characterized by thorny trees like cacti and acacias. Common animals include foxes and camels.
  4. Montane Forests: Exhibit a succession of vegetation belts based on altitude, featuring coniferous and alpine trees. This type supports fauna such as yaks and snow leopards.
  5. Mangrove Forests: Located along coastal areas, these forests thrive in tidal regions and are known for species like the Royal Bengal Tiger and various reptiles.

The significance of conserving diverse flora and fauna is highlighted, noting that India is home to 90,000 animal species and a rich variety of ecological environments.

Key Concepts

  • Tropical Evergreen Forests: Found in areas with high rainfall, characterized by consistent greenness and diverse species.

  • Tropical Deciduous Forests: Shed leaves during dry periods to conserve water, found in regions with moderate rainfall.

  • Thorn Forests: Thrive in arid conditions with plants having adaptations to conserve moisture.

  • Montane Forests: Vegetation changes with altitude, supporting unique flora and fauna at different elevations.

  • Mangrove Forests: Located in tidal zones, crucial for coastal biodiversity.
