Regarding the special corridors for the tigers, Suman said that it helps in protecting the big cats as they get disturbed due to human movement on their track.
In the Katarniaghat reserved sanctuary, a special track for tigers was created in 2006 and it has shown encouraging results. Due to the tiger track which was barred for the human as well as vehicular movement, the number of big cat has remained stable in this area. As per the tiger census of 2005, there were 77 tigers in Dudhwa followed by 58 in Katarniaghat and 29 in Kishanpur.
