How tiger’s movement was monitored?
Movement of tigers in Greater Tadoba Landscape (non PA areas outside TATR) was identified by DNA identification through scat collection. In the process, the 2000 square kilometer area outside protected area was divided into six blocks in accordance to occupancy of tigers and other large carnivores.
The team used Phase-IV camera trap (capture-recapture) technique to ascertain the exact number of tigers and leopards in these blocks. As per the guidelines for Phase-IV tiger estimation, the entire area was covered by a network of 600 camera traps for 25 days.
