Wildlife trying to cross the road is vulnerable to road kills. This was a common sight in BTR. Roads become a biological barrier to wildlife. National Highway - 67 and 212 cake cut the tiger reserve into 3 parts, thus becoming an acute barrier in Nilgiri Biosphere Reserve of which BTR is a part. Night is the most vulnerable time for wildlife getting killed by speeding vehicles "road kills were higher than poaching". In the face of these threats, WCF with the help of Wildlife Trust of India (WTI) initiated a Rapid Action Program (RAP) to minimize road kills in BTR.
