Yet, there is little joy in finding rare wildlife in the dense, lush forests of Melghat, only a sense of impending disaster. With a proposal to widen the 176-km Akola-to-Khandawa railway from metre gauge to broad gauge, 39 km of which passes through the reserve, both traffic and speed of trains are expected to increase, threatening more accidents, wildlife mortality and fragmentation of habitat, thereby isolating wildlife populations on either side of the tracks. Isolating populations can lead to genetic decay over generations in the long term. The logical end of such splintering of habitat is the local extinction of tigers, and other large, wide-ranging animals.
