Elephant grass is a robust, rhizomatous, tufted perennial grass. It has a vigourous root system, developing from the nodes of its creeping stolons. The culms are coarse, perennial, and may be up to 4-7 m in height, branched above. Elephant grass forms dense thick clumps, up to 1 m across.
1 Generally, elephants are megaherbivores and they eat up to 150 kg (330 lb) of plant matter in one day. 2  They are termed as browsers and regular grazers and are found consuming more than 100 different kinds of plants including sedge, legume, true grass, and palms.lephants seldom browse through forests that are covered with mixed tall grass but the emergence of new grass, once the rain finishes, is generally greeted by these animals. In this season, elephants consume almost 70 â 75% tall grass.
