Sightings of a Royal Bengal tiger in the Sanctuary has been reported through 2 images captured by camera traps laid by the forest Officials. The camera captured two images of the tiger on the night of December 6, 2018 - at 6.23 pm and at 7 pm, near Goru Jurey, at an altitude of 9,583 feet, according to the DFO of the region. The official also stated that there had been oral narratives of tigers freely roaming in the forests of Sikkim until the late 1980s.
And on January 2, 2019, at 4:22 PM, the camera recorded a snow leopard in the same spot. This very elusive and shy animal had earlier been captured on camera in the northern and western parts of Sikkim. However, this is the first photographic capture of a snow leopard in East Sikkim.
This image capture of both, the Bengal Tiger and the Snow Leopard, in exactly the same location confirms the overlap in the migratory routes used by the two big cats inside Pangolakha, having migrated from the neighbouring Neora Valley National Park of West Bengal, it's been further reported by the Divisional Forest Officer.
The State Forest Department has set up Eco-Development Committees around all wildlife protected areas. In this IBA an EDC has been set up in the villages of Mankhim, Dalepchand, Lingtam, Phadamchen, Zuluk and Gnathang.
