Key Points

• Biodiversity of Rajasthan:
  • Though a large percentage of the total area is desert and even though there is little forest cover, Rajasthan has rich and varied flora and fauna.
  • The natural vegetation is classed as Northern Desert Thorn Forest (Champion 1936).
  • These occur in small clumps scattered in more or less open forms.
  • The density and size of patches increase from west to east following the increase in rainfall.
  • The Northwestern thorn scrub forests lie in a band around the Thar Desert, between the desert and the Aravallis.
  • The Aravalli and the south-eastern region is home to the dry deciduous forests, with tropical dry broadleaf forests that include teak, Acacia, and other trees. Hence Sirohi is the correct answer.
  • The hilly ‘Vagad’ region lies in southernmost Rajasthan.
  • Vagad is the wettest region in Rajasthan, and the most heavily forested.
  • North of ‘Vagad’ lies the Mewar region, home to the cities of Udaipur and Chittaurgarh.
  • All these regions have varied flora and fauna distinct to the region.
