Protected areas & conservation Medium

Among the following Tiger Reserves, which one has the largest area under “Critical Tiger Habitat”?

Answer & explanation

Answer: (c) Nagarjunsagar-Srisailam

Nagarjunsagar-Srisailam has the largest Critical Tiger Habitat of the four, at 2,595.72 sq km. The other three are far smaller: Sunderban 1,699.62, Ranthambore 1,113.36 and Corbett 821.99 sq km.

  • ✓ (c) The National Tiger Conservation Authority lists a core area of 2,595.72 sq km for Nagarjunsagar-Srisailam; the core is the notified Critical Tiger Habitat. It is the largest core area among India's tiger reserves.
  • ✗ (d) Sunderban has a core of 1,699.62 sq km. Its total area (2,584.89 sq km) is close to the winner's core figure, which makes it a tempting choice, but the question asks about the critical habitat only.
  • ✗ (a) Corbett is the oldest tiger reserve in the group but its core is only 821.99 sq km.
  • ✗ (b) Ranthambore has a core of 1,113.36 sq km.

Remember · A tiger reserve = core or Critical Tiger Habitat (inviolate) + buffer. Nagarjunsagar-Srisailam has the largest core, 2,595.72 sq km.
