It is maintained as part of the Ramsar List.
    • Presently, Keoladeao NP (Rajasthan) & Loktak lake (Manipur) are part of Montreux Record Sites from India.

India: Forest Cover Snapshot

  • Total Area: 32,87,263 Sq. KM
  • Forest Cover: 21.34%  (7,01,673 Sq. Km)
  • Tree Cover: 2.82% (92,572 Sq. Km)
  • Hence, Forest Cover+ Tree Cover = 24.16 %
  • Note: All lands more than 1 hectare in area and with a Canopy density of more than 10% are called Forest Cover and if less than 1 hectare called as Tree cover.

Division of Forest Cover:

  • Terms:
    • The degraded forest, which have a Canopy density of less than 10% are called Scrubs.
    • The Lands with Canopy density of 10-40% are called Open Forests.
    • The Land with forest cover having a canopy density of 40-70% are called the Moderately Dense Forest (MDF)
    • The Lands with forest cover having a canopy density of 70% and more are called Very Dense Forests (VDF).
  • Forest Division

Division of Forest on basis of Administration:

BIODIVERSITY HOTSPOTS in INDIA:

  • What are Bio-diversity hotspots?
  • British biologist Norman Myers coined the term “biodiversity hotspot” in 1988.
  • Conservation International (CI) adopted it.
  • Hot spots are the richest and most threatened reservoirs of plant and animal life of the earth. They have maximum number of endemic species ( Original Species belonging to that ecosystem).
  • What are criteria for qualification to world biodiversity hotspot?
  • There are two Criteria’s:
    1. Species endemism: the region must contain at least 1,500 species of vascular plants (> 0.5% of the world’s total) as endemics, andBiodiversity hotspot
    2. Degree of threat: the region has to have lost at least 70% of its original habitat.
  • Bio-diversity hotspots in India:
  • India has part of 4 Major.
    • Himalaya
    • Indo-Burma
    • Western Ghats & Srilanka
    • Nicobar
