Elephant is a endanger species. Human and elephant are co-existence for a long time. People of Nepal are believed in the elephant as god Ganesh. Then, growing human population destroy the most of the forest in the Nepal. Then, human elephant conflict is seen day by day. For that reason, human elephant conflict was seen easily in the terai of Nepal. In the study time, my research team was walking 30 km per day. It is difficult to know about the actual data of human elephant conflict because of human angriness to elephant. Every day, when we started our work then all day we thought we will been met elephant. In the field time, we never felt secure from elephant. It is very difficult to research elephant in the research time. But, when it was finished then we felt sad because our perception about elephant is bad. Because elephant did not do anything when they had not felt insecure from people. So that, elephant is most amazing species in the world. We need to preserve it. Love the elephant and love the nature.
