In Nepal's Bardia National Park, elephants consume large amounts of the floodplain grass, particularly during the monsoon season. They browse more in the dry season with bark constituting a major part of their diet in the cool part of that season. During a study in a tropical moist mixed deciduous forested area of in Assam, elephants were observed to feed on about 20 species of grasses, plants and trees. Grasses such as "Imperata cylindrica" and "Leersia hexandra" constituted by far the most predominant component of their diet.
