A report prepared by the Hyderabad Centre for Cellular and Molecular Biology (CCMB) has ascertained the exact number of tigers in the Palamau Tiger Reserve, Jharkhand, to be six. The report was based on DNA analysis of scat samples collected from inside the reserve area of 1026 sq km, between June 2008 and July 2009. The samples were from Mahuadhand, Brawagarha, Baresand and Betla areas of the reserve, which are considered a Naxal stronghold. In fact, the wildlife department had approached CCMB to conduct the DNA analysis after the Wildlife Institute of India did not find any sign of tigers in the survey carried out in 2008. Also there had been no tiger sighting in the reserve since 2007. In this backdrop, the findings of the CCMB have generated hope among the environmentalists that the big cat is not extinct here.
