The natural habitat of wildlife was earlier spread over huge areas. But construction of roads, rail lines, gas pipeline, canals, electricitv transmission lines, farms, etc. has fragmented the habitats. It has badly affected the life of wild animals and they are always at risk of some accident. Many wild animals often get hit by vehicles and trains. Sometimes, an animal may stray into human settlement and may get killed by people. About half a dozen tigers and many small animals become victims to accidents on the railway line which passes through Dudhwa National Park.
