1.Thorn forests occur in semi-arid regions with rainfall less than 70 cm, like Rajasthan and Gujarat.
2.Species such as acacias, palms, and euphorbias dominate, with adaptations like succulent stems.
3.These forests provide fodder for livestock and fuelwood but have limited timber value.
4.Scrubs are degraded forms of thorn forests due to overgrazing and deforestation.
5.Thorn forests support diverse wildlife, including large herbivores like elephants.
6.Climate change may expand thorn forest areas by increasing aridity in marginal regions.
