TIGER STATUS IN SARISKA NOVEMBER - 2004 NEWS PAPERS REPORTED DISAPEARENCE OF TIGERS
TIGER STATUS IN SARISKA NOVEMBER - 2004 `TIGER TASK FORCE WAS CONSTITUTED BY RAJASTHAN GOVERNMENT. CBI investigated the cause of tiger disappearance. Poaching was the ultimate cause of tiger extinction in Sariska
Background ASSESSMENT OF STATUS OF TIGER (Panthera tigris) IN SARISKA TIGER RESERVE, RAJASTHAN The MoEF directed the WII to assess the status of tiger in Sariska (January 2005). The Institute confirmed that there were no tigers left in Sariska based on a field survey in February 2005 In the same report WII prepared a blue print for `tiger re-introduction in Sariska 2005
Background RECOVERY PLAN FOR TIGERS IN SARISKA TIGER RESERVE, RAJASTHAN Subsequently WII prepared a proposal for Tiger re-introduction in Sariska in 2006 in consultation with NTCA & Rajasthan Forest Department Based on the prey availability we assessed that an area of 274 km 2 in Sariska (notified National Park) can support 15 tigers During the first phase we proposed to re-introduce 3 tigress and 2 tigers in Sariska soft release April, 2008 Post Box 18, Chandrabani, Dehradun 248001, Uttarakhand
BACKGROUND We also proposed supplementation of three tigers (one male and two females) in every two years for a period of six years to establish self- sustaining population with high reproductive fitness in the wild environment and ample genetic diversity.
BACKGROUND The simulations (Vortex Software) showed that the probability of tiger survival as 93% (0.9380) (0.0108 SE) and probability of extinction as 0.06% (0.0620) (0.0108 SE).
JUSTIFICATION FOR RE-INTRODUCTION Sariska is the western most limit of Royal Bengal tigers in India The absence of tigers in Sariska may lead to the imbalance to the eco-system The sambar, nilgai and wild pig population went up 2 folds in Sariska (2005-2007) Sariska has an excellent prey base
JUSTIFICATION FOR RE-INTRODUCTION Continued.. Sariska and Ranthambore Tiger Reserves are located in the Aravalli hills and have identical vegetation types & temperature conditions Aravalli gene pool of tigers?
Tiger Reintroduction Operation June, 2008 Briefing of teams for the immobilization and radio-collaring operation on the 22 nd June, 2008, Ranthambore National Park
Search for suitable tiger, Ranthambore National Park
Immobilized tiger being fitted with radio-collar, Ranthambore National Park
0900 hrs, the immobilized and radio-collared tiger being transported to helipad in a well ventilated transport container
1105 hrs, tiger container being loaded in the helicopter
12.27 hrs, helicopter arrives in Sariska National Park
12.31 hrs, preparation for unloading the tiger container at the helipad located 300 meters close to tiger enclosure in Sariska National Park
12.42 hrs, container being shifted to small truck for transportation to release sites
12.41 hrs, ramps being attached to small truck for transport of tiger container to the release site
Tiger enclosure at the release site in Karnakawas beat of Sariska National Park
13.12 hrs, male tiger soon after release inside the enclosure. Animal calm, fully recovered and alert
Field operation So far 08 tigers (5 females & 3 males) were radiocollared and reintroduced in Sariska Tiger Reserve during June 2008 to January 2013.
Tiger Monitoring The radio-collared tigers were monitored regularly by a team of researchers and forest officials through ground tracking (VHF) & Satellite data till date.
WHAT WE ACHIEVED? FIRST TIME IN THE WORLD TIGER REINTRODUCTION IN A SCIENTIFIC WAY-Species recovery plan Successful immobilization, transport, and release of tigers in enclosure Successful monitoring of reintroduced tigers inside enclosure Successful release of tigers in to the wild Successful continuous monitoring of tigers in Sariska for 5 years! Panna Tiger Reserve, M.P., replicated the same protocol for tiger reintroduction. & Lot of learning

Path ahead. Initial stocking was done (05 tigers) in Sariska during 2008-12 to establish the initial population of 5 tigers. A supplementation of three tigers (one male and two females) in every two years for a period of six years is proposed. Supplementation of 2 tigress was done during January 2013 to maintain genetic and demographic viability of tiger population
ST-1 MALE ST-1 Male tiger died on 12 th November 2010. Cause of death due to poisoning (Organophosphate pesticide).
Tiger breeding status Tiger s breeding status is being ascertained through scat analysis from LaCONES, CCMB, Hyderabad (Hormone levels) Breeding success was achieved by ST-2 (female) in May-June 2012. Two female cubs are born.

Path ahead Bhagani, Umri and Rotkala villages are already relocated. Kankwari, Sukola & Dabli villages relocation which are underway will make at least 150 km 2 undisturbed area available to tigers. The relocation of remaining 8 villages from the Core-1 will make 274 km 2 undisturbed area available to tigers. This will also pave ways for inviolate atmosphere for tiger breeding in Sariska.
Path ahead Apart from 10 villages in Core Zone-1, there are 22 villages located inside the Tiger Reserve. Implementation of eco-development initiatives in all the villages will reduce the dependency of forest resources by the local people. Now we have 9 tigers in Sariska.
