Overview of Vegetation Types

Natural vegetation refers to a plant community which has grown naturally without human aid and has been left undisturbed by humans for a long time. In India, the major vegetation types include Tropical Evergreen Forests, Tropical Deciduous Forests, Tropical Thorn Forests and Scrubs, Montane Forests, and Mangrove Forests. This quiz focused on the first two types.

1. Tropical Evergreen Forests

  • Rainfall: These forests are restricted to heavy rainfall areas receiving more than 200 cm of rainfall annually with a short dry season.
  • Height: The trees reach great heights, up to 60 meters or even above.
  • Characteristics: Since the region is warm and wet throughout the year, it has luxuriant vegetation of all kinds. There is no definite time for trees to shed their leaves, so these forests appear green all year round.
  • Common Trees: Ebony, mahogany, rosewood, rubber, and cinchona.
  • Regions: Western slopes of the Western Ghats, Lakshadweep, Andaman and Nicobar Islands, and parts of Assam and Tamil Nadu coast.

2. Tropical Deciduous Forests

These are the most widespread forests of India. They are also called the monsoon forests and spread over the region receiving rainfall between 200 cm and 70 cm.

  • Shedding: Trees of this forest-type shed their leaves for about six to eight weeks in dry summer to conserve water.
  • Classification: Based on water availability, they are divided into moist and dry deciduous.
    • Moist Deciduous: Rainfall 100-200 cm. Found in eastern India, foothills of Himalayas, Jharkhand, West Odisha, Chhattisgarh. Important tree: Teak.
    • Dry Deciduous: Rainfall 70-100 cm. Found in rainier parts of the Peninsular plateau and plains of Bihar and Uttar Pradesh. Important trees: Teak, Sal, Peepal, Neem.
  • Species: Teak is the most dominant species. Other commercially important species include Bamboos, Sal, Shisham, Sandalwood, Khair, Kusum, Arjun, and Mulberry.

Extra Practice Questions

  • Q: Which forest is found in the deltas of rivers?
    A: Mangrove Forests (not covered in this specific quiz but relevant).
  • Q: What is the main characteristic of Dry Deciduous forests?
    A: They are found in areas with 70-100 cm rainfall and often transition into thorn forests in drier margins.
  • Q: Why are Evergreen forests difficult to exploit commercially?
    A: Because they are very dense and have a mix of species that do not grow in pure stands.
  • Q: In which states are dry deciduous forests prominent?
    A: Bihar and Uttar Pradesh plains.
  • Q: What animals are common in these forests?
    A: Elephants, monkeys, lemurs, and deer are common in both types.
