Forest officials said changes in the overall health of the

forests including vegetation, encroachment by villagers and the presence of other animals including elephants will be observed and recorded. "Once this exercise is over we plan to start a camera trapping exercise for tiger census with funds from the National Tiger Conservation Authority (NTCA)," Saini said. BTR also serves as international corridor for elephant migration between India and Bhutan, but wildlife conservation has been affected by poaching and timber smuggling, encroachment by villagers and uncontrolled grazing by cattle. Around 390 species of birds, 73 species of mammals, 76 species of snakes, 5 species of amphibians have been identified so far in Buxa. Besides tiger, it hosts Asian elephants, leopard cats, Bengal floricans, Regal pythons, Chinese pangolin, Hispid hare and Hog deer.
