Our data base has recorded over 600 individual tigers in past seven years. The total tiger population in Karnataka is about 250 to 300.Tiger population in India is not dwindling, at least in key reserves in south India where it is actually reaching saturation levels.In Nagarahole and Bandipur National Parks in Karnataka and bordering areas in Tamil Nadu, tiger populations have reached saturation levels with surplus young tigers spilling out into forests and dispersing through forest corridors. In newer tiger reserves including Bhadra and Kudremukh, numbers have increased by as much as 50 percent.This has emerged in new global data released by Wildlife Conservation Society (WCS), which is engaged in scientific monitoring and conservation programme in collaboration with government agencies including the National Tiger Conservation Agency."The picture is not at all dismal as often projected", said Dr Ullas Karanth, Bangalore-based conservationist who heads Asia operations of WCS. "Scientific monitoring of tiger and prey populations using techniques like Camera Trap, enhanced antipoaching patrols by government agencies and voluntary relocation of people with help from NGOs have helped in boosting tiger numbers significantly".The Camera Trap project of WCS in Karnaraka, said to be the largest such globally, has helped in scientific monitoring. "Our data base has recorded over 600 individual tigers in the past seven years, and at any given point in time the total tiger population in Karnataka is about 250 to 300", Karanth said.The overall tiger population densities in Nagarahole-Bandipur have remained high, ranging between 8 tigers per 100 square kilometer to 13 tigers per 100 square kilometres. The prey densities have also been high. "The dispersal and conflict patterns indicate that this population is producing a large surplus every year", he said. Elephants and leopards are among the wild species that share the same landscape.The monitoring and conservation aspects of the Karnataka model can be emulated in reserves elsewhere though involvement of voluntary groups could vary keeping in view local situation, the veteran conservationist said.In both states, wildlife staff vacancies have been filled up, patrolling systems have been improved with increased investments and local communities involved in conservation efforts.used to capture images of wild animals without direct human interference. Ordinary cameras are fixed at key points in a reserve, along with infrared sensors that let the camera clock whenever they sense movement in the forest. The locations are changed occasionally because their flash lights alert animals and they start avoiding the area. To distinguish one tiger from another, WCS has developed image processing software which allows speedy and reliable identification of tigers from trap photographs.
