What are the Four Features of ‘Thorn’ Forests?

Features of Tropical Thorn Forests are:

(i) Areas with an annual rainfall of less than 70 cm have open stunted forests and thorny bushes.

(ii) Rajasthan, Punjab, Haryana, parts of Gujarat and Madhya Pradesh and the dry parts of the Deccan plateau are their regions as their rainfall does not exceed 75 cm annually.

(iii) Babul, Kikar, Khair, Plums, Cactus, and Dates are important species of trees.

(iv) These forests have long roots and sharp thorns. They help them get moisture from depths. Sharp thorns protect them from animals.

Their heights vary from 6 metres to 10 metres. From east of west rainfall decreases and trees turn into small thorny bushes and shrubs. In the Thar Desert they too fade away into sand.
