Tigers were relocated to Sariska
- In 2008, tigers were relocated from Ranthambore National Park. The tigers in Ranthambore are at a risk of becoming extinct.
- According to National Tiger Conservation Authority, Ranthambore is the only source of tigers in the Ranthambore – Mukundara – Kuno – Shivpuri – Madhav landscape.
Why are tigers becoming extinct in Ranthambore National Park?
- Because here the tigers are inbred. Inbreeding deteriorates the health of the tigers generation after generation.
- Also, the tigers are declining due to purging.
- The inbred population have harmful genes circulating among them. This reduces their fitness.
- The Forest Survey of India says that the forest cover in the Rathambore Tiger Reserve has decreased.
- The total area of the tiger reserve has decreased by 44.57 square kilometres. The forests are cleared for agriculture.
What is inbreeding depression?
- Inbreeding is breeding closely related animals for many generations. Here mating of individuals closely related through common ancestry occurs.

- It is located in Alwar district of Rajasthan. It was made a tiger reserve in 1978.
- The rainfall received by the forest is around 700 millimeter per year.
