“In UP especially, intervention is required. The Environment Minister wrote to the Railway Minister suggesting a change of the railway line alignment after the Dudhwa accident,” he says.

“UP has always had a good tiger population. This is an extremely vulnerable area as it is next to the Nepal border and vulnerable to poaching,” says Belinda Wright from the Wildlife Protection Society of India.

“Not notifying critical areas is against tiger conservation and extremely unfortunate. The plan to divide a tiger reserve into a core and buffer zone was drawn by the Centre, specifically to aid tiger conservation,” says Ashok Kumar from the Wildlife Trust of India. The tiger census this year had found that the tiger population has dipped to an all time low of 1,411.

Meanwhile, on Tuesday a tiger was found dead at the Dudhwa tiger reserve , which has not been notified.
