Cenchrus purpureus, synonym Pennisetum purpureum, [1] also known as Napier grass, elephant grass or Uganda grass, is a species of perennial tropical grass native to African grasslands. [2] It has low water and nutrient requirements, and therefore can make use of otherwise uncultivated lands.
The term Elephant grass may refer to the following grass species: The Asian Miscanthus giganteus, also known as giant miscanthus, commonly used as a biomass crop; The African Cenchrus purpureus, also known as Napier grass, Uganda grass or giant king grass; The Asian Arundo donax, also known as giant cane, giant reed
Miscanthus × giganteus (Miscanthus giganteus, giant miscanthus) [A 1] is a highly productive, rhizomatous C4 perennial grass, originating from Asia. [ A 2 ] It is a sterile (noninvasive) hybrid of M. sinensis and M. sacchariflorus, and grows to heights of more than 4 m (13 ft) in one growing season (from the third season onwards).

One study of a captive female Asian elephant suggested the animal was capable of learning and distinguishing between several visual and some acoustic discrimination pairs. This individual was even able to score a high accuracy rating when re-tested with the same visual pairs a year later. [142] Elephants are among the species known to use tools.
The combined Kaziranga–Karbi Anglong Elephant Reserve has as many as 1,940 elephants. [10] The 2001 park census counted 1666 wild Asian water buffalo, [11] up 146% from 677 in 1984. The eastern swamp deer had 468 individuals in 2002, [12] down 38% from 756 in 1984. [4] This may be a reflection of the increasing tiger population.
