Sloth bear, an insect- eating animal native to Nepal, is one of the most vulnerable animals living in grassland. It may need extra protection for itself. Sloth bears coexist with and have been killed by tree- climbing leopards; they are often confronted and chased by rhinoceroses and elephants, which can topple trees; Hawks can attack them even if they stay in trees. Therefore, sloth bears will not select tree- climbing as a defensive strategy in grassland.
