Thorn Forests and Scrubs are characteristic vegetation of regions receiving less than 70 cm of annual rainfall. These forests are adapted to arid and semi-arid conditions, featuring thorny trees and bushes with long roots and small leaves to minimize moisture loss through transpiration.
Option Analysis
- Northeastern states and West Bengal.: Incorrect. The Northeastern states and West Bengal receive heavy rainfall and are characterized by Tropical Evergreen and Tropical Moist Deciduous forests.
- Western Ghats and Lakshadweep.: Incorrect. The Western Ghats and Lakshadweep are regions of high rainfall and humidity, primarily supporting Tropical Evergreen and Semi-Evergreen forests.
- Semi-arid areas of Gujarat, Rajasthan, Madhya Pradesh, and Haryana.: Correct. Thorn Forests are primarily found in the north-western part of India, covering semi-arid areas of Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Uttar Pradesh, and Haryana. The vegetation here includes species like Acacia, Palm, Euphorbia, and Cacti.
- Coastal areas of Odisha and Andhra Pradesh.: Incorrect. The coastal areas of Odisha and Andhra Pradesh are prone to cyclones and have higher moisture levels, typically supporting Littoral and Swamp forests (Mangroves) or Tropical Moist/Dry Deciduous forests.
Key Takeaway: Thorn Forests and Scrubs are strictly confined to arid and semi-arid regions with annual rainfall below 70 cm, predominantly located in North-West India and the rain-shadow regions of the Deccan Plateau.
