Situated at the southern foothills of the Himalayas the sub-tropical ‘Terai’ grasslands of Assam contain some of the tallest grass species in the world. Elephant grass, Saccharum, is the dominant grass and can grow to heights of up to 8 metres every year. Other species include Phragmites karka, Narenga porphyrocoma and Imperata cylindrica. The grasslands are a unique ecosystem which provides a diverse habitat to a range of threatened species including the pygmy hog (Porcula salvania), hispid hare (Caprolagus hispidus), Bengal florican (Eupodotis bengalensis).
The survival of pygmy hogs is closely linked to the existence of the tall, wet grasslands of the region which, besides being a highly threatened habitat itself, is also crucial for survival of a number endangered species
