Fragmentation of habitat depicts the negative impact on any habitat and directly or indirectly affects the habit. Whenever ecological requirement of tiger will disturb than other vital need will also suppressed by various means. Ecologically disturbed animal may lead towards human-dominated landscape & chances of conflict become more frequent .On the other hand remarkable anthropogenic stress on Kosi corridor i.e. construction of Resort and hotels depleted the connectivity of two vital forest( CTR& RFD) along with Kosi river. RFD (Ramnagar Forest Division) is vital for tiger, it have good density while CTR, the Corbett Tiger Reserve itself the place of roar. Kosi corridor is near about vanishing for wildlife movement in both the forest area. Vital connectivity is cut off in this forest. This study depicts the movement pattern of big cat. Food habit denotes the carrying capacity of area. On the other hand livestock predation may lead the digestive infection in animal etc. Tiger readily kill the domestic ungulates. Division like Tarai West Forest Division is very crucial. Gujjars are regular facing the livestock predation.
