TROPICAL THORN FOREST




A Thorn Forest is a dense, scrub like vegetation characteristic of dry subtropical and warm temperate areas with a seasonal rainfall less 70 cm. This type of vegetation covers a large part of north-west in India including semi-arid areas of Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Uttar Pradesh and Haryana. In South America, Thorn Forest is sometimes called Caatinga, and consists primarily of small, thorny trees that shed their leaves seasonally. Trees typically do not exceed 10 meters(33 ft.) in height, usually averaging between 7 and 8 meters (23 and 26 ft.) tall.







CLIMATIC CONDITIONS



The climatic condition found is a dense,scrub like vegetation characteristic of dry subtropical and warm temperate areas with a seasonal rainfall averaging 250 to 500 mm (9.8 to 19.7 in.). Thorn forest grades into savanna woodland as the rainfall increases and into desert as the climate becomes drier.








VEGETATION



  • The vegetation in these forest are thorny trees and the bushes.
  • Common trees found in these areas are Acacias, Palms, Euphorbia and Cacti.
  • Trees are scattered and have long roots penetrating deep into the soil in order to get moisture.
  • The stems are succulent to conserve water.
  • Leaves are modified into spines (thorns) and are small to minimize transpiration.

  • Common animals found in these areas are Rats, Mice, Rabbits,Fox, Wolf, Tiger, Lion, Wild Ass, Horses and Camels.

In India, they are found in north western parts, semi- arid areas of Gujarat, Uttar Pradesh, Madhya Pradesh and Haryana.
